RST LOCK 5 6 RESET 7 LOCK 8 LC4H • Changing the set value 1. It is possible to change the set value with the up and down keys (4digit type only) even during counting. However, be aware of the following points. 1) If the set value is changed to less than the count value with counting set to the addition direction, counting will continue until it reaches full scale (9999 with the 4-digit type and 999999 with the 6-digit type), returns to zero, and then reaches the new set value. If the set value is changed to a value above the count value, counting will continue until the count value reaches the new set value. 120 2) Suppose that the counter is preset to count down. Whether a preset countdown value is smaller or larger than the count value, the counter counts down to “0(Zero)”. 2. If the set value is changed to “0,” the unit will not complete count-up. It starts counting up when the counting value comes to “0 (Zero)” again. 1) Up-count (addition) input when counting is set to the addition direction, counting will continue until full scale is reached (9999 with the 4-digit type and 999999 with the 6-digit type), return to zero, and then complete count-up. U DOWN keys Changes the corresponding digit of the set value in the subtraction direction (downwards). I RESET switch Resets the counting value and the output. O LOCK switch Locks the operation of all keys on the counter. Y UP keys Changes the corresponding digit of the set value in the addition direction (upwards). U RESET switch Resets the counting value and the output. I LOCK switch Locks the operation of all keys on the counter. 2) Down-count (subtraction) input when counting is set to the subtraction direction, counting will continue until full scale is reached (-999 with the 4-digit type and -99999 with the 6-digit type), and then the display will change to with the 4-digit type and with the 6-digit type. The counting value does not become “0” and so the counter does not count up. 3) For directive, independent, and phase input, when the counting value increases or decreases from the value "0" and then returns back to the value "0," count-up is completed. LC4H/-L Operation modes 1. Input mode For the input mode, you can choose one of the following five modes • Addition • Subtraction UP DOWN • Directive DIR • Independent IND • Phase Input mode PHASE Operation IN1 or IN2 works as an input block (gate) for the other input. *Minimum input signal width 30 Hz: 16.7 ms; 5 kHz: 0.1 ms • Example where IN1 is the count counting and IN2 is the input block (gate).

Setting procedure 3) Setting the input mode The input mode is set using the key switch in the [Display] section on the front of the counter. • Decimal point position setting mode Q Holding down the [SET/LOCK] key, press the key for the second digit to access the decimal point position setting mode. Example) 6-digit type Decimal point position setting mode display (Example shows default value displayed) W When the setting mode has been accessed, release the [SET/LOCK] key. 127 LC4H-S E The decimal point is set using the [UP] and [DOWN] keys to specify the 2nd, 3rd, and 4th digits (this applies only to 4-digit models).(The 1st digit is set using the [UP] key or [DOWN] key in settings where there is no decimal point (this applies only to 4-digit models).) Example) 6-digit type Example shows 2nd digit displayed using [UP] key R Press the [RESET] key to set the displayed decimal point position and return to normal operation. • Setting the pre-scaling value Q Holding down the [SET/LOCK] key, press the key for the first digit to access the pre-scaling value setting mode. Example) 4-digit type Example) 6-digit type Pre-scaling value setting mode displayed (Example shows default values displayed) W When the setting mode has been accessed, release the [SET/LOCK] key. E Use the [UP] or [DOWN] key to set the pre-scaling value (this applies only to 4-digit models). Select either: 0.001 to 9.999 (4-digit) or 0.001 to 99.999 (6-digit) R Press the [RESET] key to set the displayed pre-scaling value and return to normal operation. • Setting the one-shot output time Q Holding down the [SET/LOCK] key, press the key for the third digit to access the one-shot output time setting mode. Example) 6-digit type One-shot output time setting mode displayed (Example shows default value displayed) W When the setting mode has been accessed, release the [SET/LOCK] key. E Each time the 1st-digit [UP] key is pressed, the one-shot output time changes in the following sequence, moving to the right: → 1 s → 0.5 s → 0.2 s → 0.1 s → 0.05 s → 0.01 s (With a 4-digit type, the [DOWN] key can also be used to move to the left.) R Press the [RESET] key to set the displayed one-shot output time and return to normal operation. Changing the set value 1. It is possible to change the set value with the up and down keys (4digit type only) even during counting. However, be aware of the following points. 1) If the set value is changed to less than the count value with counting set to the addition direction, counting will continue until it reaches full scale (9999 with the 4-digit type and 999999 with the 6-digit type), returns to zero, and then reaches the new set value. If the set value is changed to a value above the count value, counting will continue until the count value reaches the new set value. 2) Suppose that thew counter is preset to count down. Whether a preset countdown value is smaller or larger than the count value, the counter counts down to “0 (zero)”. 2. If the set value is changed to “0,” the unit will not complete count-up. It starts counting up when the counting value comes to “0 (zero)” again. 1) Up-count (addition) input When counting is set to the addition direction, counting will continue until full scale is reached (9999 with the 4-digit type and 999999 with the 6-digit type), return to zero, and then complete countup. 2) Down-count (subtraction) input When counting is set to the subtraction direction, counting will continue until full scale is reached (-999 with the 4-digit type and -99999 with the 6-digit type), and then the display will change to with the 4-digit type and with the 6-digit type. The counting value does not become “0 (zero)” and so the counter does not count up. 3) Directive, independent, and phase inputs The counting value is counted up or down to any number other than “0” once. When it comes to “0 (zero)” again, the counter starts counting up.

Procedure 3) Setting the input mode Set the input mode using the key and switch in the front display section on the counter front. (1) Hold down the SET/LOCK key and press the UP key for the first digit. The setting mode is accessed. (2) Now release the SET/LOCK key. (3) Press the UP key for the first digit and the input position changes counterclockwise. Addition subtraction Directive Independent Example) Input mode displayed (UP: addition mode) Phase difference (4) Press the RESET key and the input mode being displayed is set. The display then goes back to normal. • Checking the input mode • Changing the setting Hold down the SET/LOCK key and press the UP key for the second digit. The input mode is displayed for about 2 seconds and then the display goes back to normal. (During these 2 seconds, all operations other than the display are being performed.) 1. While the counter is working, the UP key can be used to change the setting. Keep the following points in mind, however. 1) Suppose that a preset count-up value is smaller than the displayed count value. The counter counts up to the full scale mark (999999), goes back to "0", and counts up again to the preset number. When the preset count-up value is larger than the displayed count value, the counter counts up to the preset value. 2) Suppose that the counter is preset to count down. Whether a preset count-down value is smaller or larger than the count value, the counter counts down to "0". • Locking the keys Hold down the SET/LOCK key and press the UP key for the sixth digit. The keys will lock. This means that the UP and RESET keys do not respond to touch. To unlock the keys,hold down the SET/LOCK key and press the UP key for the sixth digit again. * The input mode, maximum counting speed and minimum reset signal width cannot be preset independently for Setting 1 and Setting 2. • Selecting the Setting 1 or Setting 2 display 2. When the preset value is "0", the counter does not start in the count-up mode. It starts counting up when the count value comes to "0" again. 1) Up-count input The counter counts up to the full scale mark (999999), goes back to "0" and starts counting up again. 2) Down-count input The counter counts down to the full scale mark (–99999) and the display reads . The count value does not become "0" and so the counter does not count up. 3) Direction input, individual input, and phase input The preset value is counted up or down to any number other than "0" once. When it comes to "0" again, the counter starts counting up. Press the SET/LOCK key and the display changes between Setting 1 and Setting 2. (This operation does not affect overall operation.) 135 LC4H-W Operation modes 1. Input mode Q For the input mode, you can choose one of the following five modes. • Addition • Subtraction UP DOWN • Directive DIR • Independent IND • Phase PHASE W After the counter has been reset, setting 2 is displayed in the count-down mode.

Count-up (1) In control output 1, when the count value is equal to the preset value 1, it is counted. (However, if the output mode of the preset value 1 is HOLD-D, it is counted when the count value is greater than or equal to the preset value 1, regardless of the input mode.) (2) In control output 2, when the count value is equal to 0 in the count-down input mode, it is counted. In the other modes, when the count value is equal to the preset value 2, it is counted. (However, if the output mode of the preset value 2 is HOLD-D, it is counted when the count value is greater than or equal to the preset value 2, regardless of the input mode.) (3) It is not counted even when the counting conditions are satisfied right after resetting. It can be counted from when the count value changes. 139 PRECAUTIONS IN USING THE LC4H SERIES Precautions during usage 1. Terminal wiring 1) When wiring the terminals, refer to the terminal layout and wiring diagrams and be sure to perform the wiring properly without errors. 2) When using the instrument with an flush mounting, the screw-down terminal type is recommended. For the pin type, use either the rear terminal block (AT78041) or the 8P cap (AD8-RC) for the 8-pin type, and the rear terminal block (AT78051) or the 11P cap (AT8DP11) for the 11-pin type. Avoid soldering directly to the round pins on the unit. When using the instrument with a front panel installation, use the DIN rail terminal block (AT8-DF8K) for the 8-pin type and the DIN rail terminal block (AT8DF11K) for the 11-pin type. 3) After turning the counter off, make sure that any resulting induced voltage or residual voltage is not applied to power supply terminals W through U (8pin type), W through P (11-pin type) or 1 and 2 (screw terminal type). (If the power supply wire is wired parallel to the high voltage wire or power wire, an induced voltage may be generated between the power supply terminals.) 4) Have the power supply voltage pass through a switch or relay so that it is applied at one time. If the power supply is applied gradually, the counting may malfunction regardless of the settings, the power supply reset may not function, or other such unpredictable occurrence may result. 2. Input connections (except LC4HS/AC type) The power circuit has no transformer without a transformer (power and input terminals are not insulated). When an input signal is fed to two or more counters at once, do not arrange the power circuit in an independent way. If the counter is powered on and off independently as shown in Fig. A, the counter's internal circuitry may get damaged.Be careful never to allow such circuitry. (Figs. A, B and C show the circuitry for the 11-pin type.) (Fig. A) Input contact or transistor 2 Input terminal 3 2 140 10 10 Power supply Also, use transistors with a residual voltage of less than 2 V when the transistor is on. Reset input (Fig. B) Input 1 Input contact or transistor Input 2 Lock input Input terminal 3 10 2 Power supply Input contact or transistor Input terminal 3 10 2 When power circuitry is not independent, one input signal can be fed to two or more counters at once, as shown in Fig. C.

Input and output 1) Signal input type (1) Contact point input Use highly reliable metal plated contacts. Since the contact point’s bounce time leads directly to error in the count value, use contacts with as short a bounce time as possible. In general, select Input 1 and Input 2 to have a maximum counting speed of 30 Hz and to be reset with a minimum input signal width of 20 ms. * The short-circuit impedance should be less than 1 kΩ. [When the impedance is 0 Ω, the current coming from the input 1 and input 2 terminals is approximately 12 mA, and from the reset input and lock input terminals is approximately 1.5 mA.] Also, the open-circuit impedance should be more than 100 kΩ. * As shown in the diagram below, from a non-contact point circuit (proximity switches, photoelectric switches, etc.) with a power supply voltage of between 12 and 40 V, the signal can be input without using an open collector transistor. In the case of the diagram below, when the non-contact point transistor Q switches from off to on (when the signal voltage goes from high to low), the signal is input. 12 to 40V DC Reset input Q Reset input Input 1 Input 2 Lock input 8-pin type 1 — 5 4 11-pin type 3 4 5 6 7 Screw terminal type 6 7 8 9 10 3 (The above example is for reset input) 8-pin type 1 — 5 4 11-pin type 3 4 5 6 7 Screw terminal type 6 7 8 9 10 3 Note: The LC4H-W does not have the lock input R, 7 . Input terminal 3 If independent power circuitry must be used, keep the input contacts or transistors separate from each other, as shown in Fig. B. (2) Non-contact point input Connect with an open collector. Use transistors whose characteristics satisfy the criteria given below. VCEO = 20 V min. IC = 20 mA min. ICBO = 6µA max. 2) The input mode and output mode change depending on the DIP switch settings. Therefore, before making any connections, be sure to confirm the operation mode and operation conditions currently set. PRECAUTIONS IN USING THE LC4H SERIES • Surge wave form [± (1.2 × 50) ms uni-polar full wave voltage] LC4H counter As NPN output { O Load Load’s power supply { O Load Load’s power supply Note: With the LC4H 8-pin type and the LC4H-W, there is no diode between points I and O. (2) Use the diode connected to the output transistor’s collector for absorbing the reverse voltage from induced loads. (LC4H only) LC4H counter VR (reverse voltage): 600 V (+) Input device (e.g., sensor) (–) Load’s power supply 6) When wiring, use shielded wires or metallic wire tubes, and keep the wire lengths as short as possible. (–) Counter (Fig. B) Bad example AC power supply Insulation transformer (+) Input device (e.g., sensor) (–) (–) Counter AC power supply Single coil transformer (+) Input device (e.g., sensor) (–) (–) Counter Alternative current flow 4) The input signal is applied by the shorting of each input terminal with the common terminal (terminal Q for 8-pin type, terminal E for 11-pin type and terminal 6 for screw terminal types). Never connect other terminals or voltages higher than 40 V DC , because it may destroy the internal circuitry. 5) Transistor output (1) Since the transistor output is insulated from the internal circuitry by a photocoupler, it can be used as an NPN output or PNP (equal value) output. (The above example is 11-pin type) 0 1.2 4. Output mode setting The output mode can be set with the DIP switches on the side of the counter. Make the DIP switch settings before installing the counter on the panel. 5. Conditions of usage 1) Avoid locations subject to flammable or corrosive gases, excessive dust, oil, vibrations, or excessive shocks. 2) Since the cover of the unit is made of polycarbonate resin, avoid contact with or use in environments containing methyl alcohol, benzene, thinners, and other organic solvents; and ammonia, caustic sodas, and other alkaline substances. 3) If power supply surges exceed the values given below, the internal circuits may become damaged. Be sure to use surge absorbing element to prevent this from happening. 4) Regarding external noise, the values Operating voltage Surge voltage (peak value) AC type 6,000V DC type 1,000V 24V AC type 50 Time (µs) I IF (forward current): 1 A Insulation transformer 30 0 Diode rating: AC power supply Peak value 50 LC4H counter As PNP output Inductive load (Fig. A) Good example 100 90 I Surge voltage (%) 3) The LC4H series use power supply without a transformer (power and input terminals are not insulated). In connecting various kinds of input signals, therefore, use a power transformer in which the primary side is separated from the ungrounded secondary side as shown in Fig. A, for the power supply for a sensor and other input devices so that short-circuiting can be prevented. Once the wiring to be used is completely installed and prior to installing this counter, confirm that there is complete insulation between the wires connected to the power terminals (2 each) and the wires connected to each input terminal. If the power and input lines are not insulated, a short-circuit may occur inside the counter and result in internal damage. In addition, when moving your equipment to a new installation location, confirm that there is no difference in environmental conditions as compared to the previous location. (except LC4H-S/AC type) below are considered the noise-resistant voltages. If voltages rise above these values, malfunctions or damage to the internal circuitry may result, so take the necessary precautions. Noise wave form (noise simulator) Power supply terminals Input DC type terminals AC type 24V AC type Noise voltage 1,500V 1,000V 600V Rise time: 1 ns Pulse width: 1 µs, 50 ns Polarity: ± Cycle: 100 cycles/second 5) When connecting the operation power supply, make sure that no leakage current enters the counter. For example, when performing contact protection, if set up like that of diagram A, leaking current will pass through C and R, enter the unit, and cause incorrect operation. Diagram B shows the correct setup.

Compliance with the CE marking When using in applications to which EN61812-1 applies, abide by the following conditions. • Overvoltage category II, pollution level 2 (for sensor type model with power supply) 1. Connections between the power supply and input/output have basic insulation. Use a device with basic insulation to connect to the I/O terminals. (for sensor type model without power supply) 1) This counter employs a power supply without a transformer, so the power and input signal terminals are not insulated. 142 (1) When a sensor is connected to the input circuit, install double insulation on the sensor side. (2) In the case of contact input, use dualinsulated relays, etc. • The load connected to the output contact should have basic insulation. This counter is protected with basic insulation and can be double-insulated to meet EN/IEC requirements by using basic insulation on the load. • Applied voltage should be protected with an overcurrent protection device (example: 250 V 1A fuse, etc.) that conforms to the EN/IEC standards. 2) You must use a terminal block or socket for installing the pin-type counter. Do not touch the terminal section or other parts of the timer unit while an electric current is applied. Before installation or removal, confirm that there is no voltage being applied to any of the terminals. 3) Do not use this timer with a safety circuit. For example, when using a timer in a heater circuit, etc., provide a protection circuit on the machine side. COUNTERS SELECTOR CHART Classification Name of product Type LC2H Counter Total counter LC2H Counter Preset counter UP type UP, DOWN type Input mode/Input method Contact output (1 Form C) Open collector output Contact output (1 Form A) Electronic counters LC4H/-L Counter Preset counter LC4H-S Counter Preset counter UP, DOWN, and DIR (multi-mode)/DIP switch UP, DOWN, and DIR (multi-mode)/DIP switch LC4H-W Counter Preset counter UP, DOWN, and DIR (multi-mode) 2 modes selectable/DIP switch Flush mounting type Appearance PC board mounting type 4-digit display 6-digit display AEL3 8.7 mm tall 8-digit display Preset function equipped in half size Display has backlight for instant recognition Flush mounting type: Unnecessary (Built-in battery) PC board mounting type: 3 V DC (Battery in externally installed) 24 V DC 100 to 240 V AC 24 V AC, 12 to 24 V DC 8-digit 8-digit 4-digit 6-digit Features Rated operating voltage 4-digit display AEL3 8.7 mm tall 8-digit display Bright 2-color back light 6-digit display Bright and easy-to-read display Simple operation Pre-scale function Built-in power supply for highcapacity sensor (100 to 240 V AC type) Conforms to IP66’s weather resistant standards 100 to 240 V AC Bright and easy-to-read display Simple operation Short body Conforms to IP66’s weather resistant standards 4-digit 6-digit Bright and easy-to-read display Simple operation Upper and lower limit settings are available.

Electro Preset Counter The counter is equipped with semiconductor counting circuitry. When the counter counts up to a preset number, its output circuit sends a signal. 2. Electro Magnetic Counter A magnet is magnetized and demagnetized to drive the dial and count up numbers. RATING 1. Rated Operating Voltage The voltage is applied to start the counter. COUNTINGS 1. Pulse This is a voltage or current signal sent at intermittent time intervals. 2. Count Pulses are used to count up and down. 3. Miss-count This happens if the number of pulses does not correspond to the number of counts. 8. Recount When counting is up, the counter display resets to zero and counting restarts. 9. Down Count Numbers are counted down one by one from a preset number. 10. Up Count Numbers are counted up one by one from zero. 11. Up/Down Count Numbers are counted up or down depending on input conditions. 12. Rejection (gate) Input This signal is used to keep the counter from counting. OUTPUTS 1. Count Up When a preset number is reached, the output circuit sends a signal. 2. Retained Output The output is held until a reset signal is sent. 4. Hertz This unit of counting speed is used to give the number of counts per one second. 3. One Shot Output This output has a specified width of time. 5. Make Ratio This is the ratio of ON time (Ta) to OFF time (Tb). 1. Reset The counting process, display and output sections are all brought back to the initial status. Ta Tb Time 6. Maximum Counting Speed Suppose that the counter is operated with an input pulse of a make ratio of 1. The highest counting speed is the peak of a range in which the output circuit can send signals without mis-counting. The speed is expressed in units of Hz (cps: counts per a second). 5. Automatic Reset When counting is up, internal circuitry is activated to automatically reset the counter. 6. Reset Signal Width This is the time during which the power is off so as to reset the counter or during which an external (manual) reset signal is sent. 7. Reset time This is the time from the moment a reset signal is sent to the instant the counter is ready to start counting again. OTHERS 1. Function of Memorizing Condition Counting data up until the operating voltage is turned off can be stored in memory. When the power is reactivated, the data can be reproduced. 2. Anti-surge The strength against power voltage surge is determined by applying a singlepole full-wave voltage (several hundred to several thousand volt wave for ±(1.2 × 50) µs) acrosss the control power terminals. Surge waveform [Single-pole full-wave voltage for ±(1.2 × 50) µs] RESETTINGS 2. Power off Reset The operating voltage is turned off to reset the counter. 3. Manual Reset The counter is manually reset. Surge voltage (%) TYPES OF COUNTERS 100 90 Peak value 50 30 0 0 1.2 50 Time (µs) 3. Noise Immunity This is the strength against external noise. Relay noise tests, noise simulator tests, etc. are conducted. 4. Remote Reset A signal is sent from a remote point to the reset terminal so as to reset the counter. 7. Over Count Counting continues beyond a preset number. 95 PRECAUTIONS IN USING THE COUNTER Cautions for circuits 1. Protective circuit for counter contact In the circuit that switches an inductive load, a contact failure may occur at a contact point due to surge or inrush current resulting from that switching. Therefore, it is recommended that the following protective circuit be used to protect the contact point. Application AC DC (see note.) Available r c Diode Available Available If the load is a relay or solenoid, the release time lengthens. Effective when connected to both contacts if the power supply voltage is 24 or 48 V and the voltage across the load is 100 to 200 V. Features/Others Device Selection If the load is a timer, leakage current flows through the CR circuit causing faulty operation. — Note: If used with AC voltage, be sure the impedance of the load is sufficiently smaller than that of the CR circuit. As a guide in selecting r and c, c: 0.5 to 1 µF per 1 A contact current r: 0.5 to 1 Ω per 1 V contact voltage Values vary depending on the properties of the load and variations in counter characteristics. Capacitor c acts to suppress the discharge the moment the contacts open. Resistor r acts to limit the current when the power is turned on the next time. Test to confirm. Use a capacitor with a breakdown voltage of 200 to 300 V. Use AC type capacitors (non-polarized) for AC circuits. 2. Type of Load and Inrush Current The type of load and its inrush current characteristics, together with the switching frequency, are important factors which cause contact welding. Particularly for loads with inrush currents, measure the steady state current and inrush current and use a relay or magnet switch which provides an ample margin of safety. The table below shows the relationship between typical loads and their inrush currents. ZNRvaristor Not available Available The diode connected in parallel causes the energy stored in the coil to flow to the coil in the form of current and dissipates it as joule heat at the resistance component of the inductive load. This circuit further delays the release time compared to the CR circuit. (2 to 5 times the release time listed in the catalog) Use a diode with a reverse breakdown voltage at least 10 times the circuit voltage and a forward current at least as large as the load current. In electronic circuits where the circuit voltages reverse breakdown voltage of about 2 to 3 times the power supply voltage. various kinds of input signals, therefore, use a power transformer in which the primary side is separated from the ungrounded secondary side as shown in Fig. A, for the power supply for a sensor and other input devices so that short-circuiting can be prevented. (Fig. A) Good Inductive load c Varistor circuit Counter contact Inductive load r Diode circuit Counter contact Inductive load Circuit Inductive load CR circuit (r: resistor c: capacitor) Counter contact Counter contact Available Available Using the rated voltage characteristics of the varistor, this circuit prevents excessively high voltages from being applied across the contacts. This circuit also slightly delays the release time. — 4. Long Continuous Current Flow Avoid keeping the counter on for a long period of time (over one month). Otherwise heat is generated and accumulated inside the counter, which may deteriorate its electronic parts. If the counter must be kept on for a long period of time, a relay is added. See the circuit diagram below. Insurating transformer (+) Input equipment (sensor, etc.) (–) C R R R (–) Type of load Resistive load Solenoid load Motor load Incandescent lamp load Mercury lamp load Sodium vapor lamp load Capacitive load Transformer load Inrush current Steady state current 10 to 20 times the steady state current 5 to 10 times the steady state current 10 to 15 times the steady state current 1 to 3 times the steady state current 1 to 3 times the steady state current 20 to 40 times the steady state current 5 to 15 times the steady state current When you want large load and long life of the counter, do not control the load direct with a counter. When the counter is designed to use a relay or a magnet switch, you can acquire the longer life of the counter. 3. Connection of input (Except for LC4H-S/AC type) The LC4H series use power supply without a transformer (power and input terminals are not insulated). In connecting 96 Counter R (Fig. B) No good AC power supply Insurating transformer (+) Input equipment (sensor, etc.) (–) (–) Counter AC power supply Single coil transformer (+) Input equipment (sensor, etc.) (–) (–) Counter AC power routing Do not use a single coil transformer (e.g., Sly-Duck). Otherwise, the internal circuit of the counter will be short-circuited as shown in Fig. B resulting in breakdown. Relay C Counter Receive output from contact at relay R PRECAUTIONS IN USING THE COUNTER Cautions for use (common for all models) 1. Terminal connections Correctly connect the pins while seeing the terminal layout/wiring diagram. In particular, the DC type, which has polarities, does not operate with the polarities connected reverse. Any incorrect connection can cause abnormal heating or ignition. 2. Connection to operating voltage 1)Apply the entire supply voltage through a switch, relay or other contact. 2) The operating voltage for the DC type must be at the specified ripple percentage or less. The average voltage must fall within the allowable operating voltage range. (Fig. A) Leakage current R R Operating voltage C C Counter 5. Superimposed surge of power supply For the superimposed surge of power supply, the standard waveform (±1.2 × 50µs or ±1 × 40µs) is taken as the standard value for surge-proof voltage. (The positive and negative voltages are applied each three or five times between the power pins.) For the standard values for the LC4H type counters, see the respective items in "Cautions for use." • Single-pole, full-wave voltage for surge waveform [±(1.2 × 50) µs] 100 90 C C Ripple percentage Approx. 48% Approx. 4% Approx. 17% 3) Make sure that no induced voltage and residual voltage are applied between the power terminals on the counter after the power switch is turned OFF. (If the power line is wired in parallel with the high-voltage and motor lines, induced voltage may be produced between the power pins.) 3. Control output 1) Keep the load capacity below the counter's rated control capacity. If used above the rating, the counter's service life may shorten. With the transistor output type counters, transistors may be damaged. 4. Installing the counter 1) To install the counter, use the dedicated pin bracket or socket (cap). Avoid connecting the pins on the counter by directly soldering them. 2) In order to maintain the characteristics, do not remove the counter cover (case). Counter 3) The counter cover (case), the knobs, and the dials are made of polycarbonated resin. Therefore, prevent the counter from being exposed to organic solvents such as methyl alcohol, benzine, and thinner, strong acid substances such as caustic soda, and ammonia and avoid using the counter in atmosphere containing any of those substances. 4) If the counter is used where noises are emitted frequently, separate the input signal elements (such as a sensor), the wiring for the input signal line, and the counter as far as possible from the noise source and the high power line containing noises. Input line Peak value Sensor, etc. 50 30 Counter Rectification type Single-phase, full-wave Three-phase, full-wave Three-phase, half-wave 2) If the counter is directly switched with a non-contact element, leak current may flow into the counter and cause it to malfunction. (Fig. B) Operating voltage Surge voltage (%) 5. Leakage current 1) For connecting operating voltage to the counter, a circuit should be used, which will prevent the flow of leakage current. For example, a circuit for contact protection as shown in Fig A. will permit leakage current flow through R and C, causing erroneous operation of the counter. Instead, the circuit shown in Fig. B should be used. 0 0 1.2 As remote as possible 50 Time (µs) If external surge occurs exceeding the specified value, the internal circuit may break down. In this case, use a surge absorption element. The typical surge absorption elements include a varistor, a capacitor, and a diode. If a surge absorption element is used, use an oscilloscope to see whether or not the foreign surge exceeding the specified value appears. 6. Signal input The counter's signal input comes in two ways. One is by opening and closing the input terminal. The other is by applying a specified H-level or L-level voltage to the input terminal. For an input sensor's residual voltage, input impedance, input voltage level and other signal input conditions, see the ratings for each type of product. 7. Operating environment 1) For the ambient operating temperature and humidity, see the ratings for each type of product. 2) Avoid using the counter in a location where inflammable or corrosive gas is generated, the counter is exposed to much dust and other foreign matter; water or oil is splashed on the counter; or vibrations or shocks are given to the counter. Power line, etc. 8. Checking the actual load In order to increase the reliability in the actual use, check the quality of the counter in the actual usage. 9. Others 1) If the counter is used exceeding the ratings (operating voltage and control capacity), the contact life, or any other specified limit, abnormal heat, smoke, or ignition may occur. 2) The LC2H series counter, incorporates a lithium battery. Never disassemble the lithium battery or throw it into fire because this may affect humans and facilities. The lithium battery must be disposed of as an incombustible like other used batteries. 3) If any malfunction of the counter is likely to affect human life and properties, give allowance to the rated values and performance values. In addition, take appropriate safety measures such as a duplex circuit from the viewpoint of product liabilities. 97 DIN SIZE COUNTERS COMMON OPTIONS Terminal sockets (Unit: mm inch, Tolerance: ±1 ±.039) Type Appearance Terminal wiring (Top view) Dimensions Mounting hole dimensions • DIN rail socket (8-pin) 24 .945 19 .748 50 1.969 M3.5 M.138 40 1.575 6 LC4H LC4H-L (8-pin type) 6 24 .945 4 70 2.756 35.3 1.390 7 8 1 4 50 1.969 3 2– φ 4.5 2– φ .177 3 70 2.756 70 2.756 50 1.969 5 5 70 2.756 7 8 1 40±0.2 1.575±.008 13 .512 Note: Terminal No. on the main body are identifical to those on the terminal socket. 2 4 .157 ATC180031 2-M4 2-M.157 screw holes (or 4.2 ±0.1 .165±0.1 dia. holes) 2 The minimum distance between the holes which areparallel drilled. • DIN rail socket (11-pin) 30.5 1.201 29.5 1.161 50 1.969 M3.5 M.138 40 1.575 8 LC4H LC4H-L LC4H-S LC4H-W (11-pin type) 7 6 30.5 1.201 4 70 2.756 4 70 2.756 70 2.756 50 1.969 50 1.969 8 7 6 5 2- φ 4.5 2- φ .177 5 35.3 1.390 9 10 9 2-M4 2-M.157 screw holes (or 4.2 ±0.1 .165±0.1 dia. holes) 3 10 11 1 2 3 11 1 Note: Terminal No. on the main body are identifical to those on the terminal socket. 2 4 .157 ATC180041 40±0.2 1.575±.008 13 .512 The minimum distance between the holes which areparallel drilled.

Surface mount 1) For the counters of LC4H series, use the pin type counter. 2) How to mount the counter From the panel front, pass the counter through the square hole. Fit the mounting frame from the rear, and then push it in so that the clearance between the mounting frame and the panel surface is minimized. In addition, lock the mounting frame with a screw. 2) Put the terminal socket on the board directly or put it on the DIN rail (Fig. 1). 3) Insert the counter into the terminal socket and fix it with clip (Fig. 2) 4) On DIN rail mounting, mount the counter on the DIN rail tightly to get the proper dimension (Fig. 3). • LC4H series (Fig. 1) Panel cover Mounting flame +0.6 0 +.024 0 PUSH +0.6 0 +.024 0 (Fig. 2) Screw +0.6 0 +.024 0 Rubber gasket Terminal socket (Fig. 3) DIN rail 5) 8-pin type should be connected with terminal socket AT8-DF8K. 11-pin type should be connected with terminal socket AT8-DF11K. 6) DIN rail (AT8-DLA1) is also available (1 m). 2. Flush mount 1) For the counters of LC4H series, it is recommended to use the built-in screw terminal type for flush mount. (Mounting frame and rubber gasket are provided when counter is shipped.) 5) Correctly connect the terminals while seeing the terminal layout and wiring diagram. 6) If the pin type is used, the rear pinbracket (AT8-RR) or the 8P cap (AD8RC) is necessary to connect the pins. For the 11-pin type, use the 11P cap (AT8-DP11) and avoid directly soldering the round pins on the counter. 7) Panel cutout dimensions The standard panel cutout dimensions are 45 shown in the left fig1.772 ure. (Panel thickness: 45 1 to 5 mm .039 to .197 1.772 inch) 8) Although the Min. 80 3.150 counters can be 45 1.772 mounted adja45 cent to each 1.772 other in this 80 case, it is rec- Min. 3.150 ommended to arrange the mounting holes as shown in the figure to facilitate attaching 45 1.772 and detaching the mounting A frame. 9) Adjacent mounting Although the counters can be mounted adjacent to each other, remember that the panel surface of LC4H series counter will lose its water-resistant effect. (Panel thickness: 1 to 5 mm .039 to .197 inch) A = (48 × n – 2.5) +0.6 +0 When lining up the counters horizontally, set the frames in such a position so the formed spring areas are at the top and bottom. When lining up the counters vertically, set the frames in such a position Formed spring as the formed spring areas are at the right and left. 3) Caution in mounting the counter • LC4H series
a If the LC4H series are used as the waterproof types (IEC IP66), tighten the reinforcing screws on the mounting frames so that the counters, the rubber gaskets, and the panel surfaces are tightly contacted with each other. (Tighten the two screws with uniform force and make sure that there is no rattling. If the screws are tightened too excessively, the mounting frame may come off.)
b If the counter is installed with the panel cover and the rubber gasket removed, the waterproofing characteristic is lost. 4) Removal Loosen the screws on the mounting frame, spread the edge of frame and remove it.

Europe IEC standard EN standard International Electrotechnical Commission By promoting international cooperation toward all problems and related issues regarding standardization in the electrical and electronic technology fields, the IEC, a non-governmental organization, was started in October, 1908, for the purpose of realizing mutual understanding on an international level. To this end, the IEC standard was enacted for the purpose of promoting international standardization. 2. North America LISTING MARK Fig. 1 RECOGNITION MARK Fig. 2 Certification Fig. 3 Component Acceptance Fig. 4 Fig. 5 UL (Underwiters Laboratories Inc.) This is a non-profit testing organization formed in 1894 by a coalition of U.S. fire insurance firms, which tests and approves industrial products (finished products). When electrical products are marketed in the U.S., UL approval is mandated in many states, by state law and city ordinances. In order to obtain UL approval, the principal parts contained in industrial products must also be ULapproved parts. UL approval is divided into two general types. One is called “listing” (Fig. 1), and applies to industrial products (finished products). Under this type of approval, products must be approved unconditionally. The other type is called “recognition” (Fig. 2), and is a conditional approval which applies to parts and materials. CSA (Canadian Standards Association) This was established in 1919 as a non-profit, nongovernmental organization aimed at promoting standards. It sets standards for industrial products, parts, and materials, and has the authority to judge electrical products to determine whether they conform to those standards. The CSA is the ultimate authority in the eyes of both the government and the people in terms of credibility and respect. Almost all states and provinces in Canada require CSA approval by law, in order to sell electrical products. As a result, electrical products exported from Japan to Canada are not approved under Canadian laws unless they have received CSA approval and display the CSA mark. Approval is called “certification”, and products and parts which have been approved are called “certified equipment”, and display the mark shown in Fig. 3. The mark shown in Fig. 4 is called the “Component Acceptance” mark, and indicates conditional approval which is applicable to parts. The C-UL mark shown in Fig. 5 (finished products) and Fig. 6 (parts) indicates that the product has been tested and approved in UL laboratories, based on UL and CSA standards, through mutual approval activities. European Standards/Norme Europeennee (France)/Europaishe Norm (Germany) Abbreviation for European Standards. A unified standard enacted by CEN/CENELEC (European Standards Committee/European Electrical Standards Committee). EU and EFTA member nations employ the content of the EN standards into their own national standards and are obligated to abolish those national standards that do not agree with the EN standards. (1) Germany VDE TÜV Rheinland VDE (Verband Deutscher Elektrotechniker) The VDE laboratory was established mainly by the German Electric Technology Alliance, which was formed in 1893. It carries out safety experiments and passes approval for electrical devices and parts. Although VDE certification is not enforced under German law, punishment is severe should electrical shock or fire occur; therefore, it is, in fact, like an enforcement. TÜV (Technischer Überwachungs-Verein) TÜV is a civilian, non-profit, independent organization that has its roots in the German Boiler Surveillance Association, which was started in 1875 for the purpose of preventing boiler accidents. A major characteristic of TÜV is that it exists as a combination of 14 independent organizations (TÜV Rheinland, TÜV Bayern, etc.) throughout Germany. TÜV carries out inspection on a wide variety of industrial devices and equipment, and has been entrusted to handle electrical products, as well, by the government. TÜV inspection and certification is based mainly on the VDE standard. TÜV certification can be obtained from any of the 14 TÜVs throughout Germany and has the same effectiveness as obtaining VDE certification. 4. Shipping Standards (1) Lloyd’s Register of Shipping Standards from the Lloyd’s Register shipping association based in England. These standards are safety standards for environmental testing of the temperature and vibration tolerances of electrical components used for UMS (unmanned machine rooms in marine vessels) applications. These standards have become international standards for control equipment in all marine vessel applications. No particular action is taken to display the conformation to these standards on the products. Fig. 6 183 5. Pilot Duty One of the specifications in the “UL508 Industrial Control Equipment” regulations at UL (Underwriters Laboratories Inc.), has to do with the grade of contact control capacity by NEMA (National Electrical Manufacturers Association) standards.

The world’s largest single market, the European Community (EC) was born on 1 January 1993 (changing its name to EU in November 1993. It is now always expressed as EU, apart from EC directives.) EU member country products have always had their quality and safety guaranteed according to the individual standards of each member country. However, the standards of each country being different prevented the free flow of goods within the EU. For this reason, in order to eliminate non-tariff barriers due to these standards, and to maximize the merits of EU unification, the EC directives were issued concomitant to the birth of the EU. The EN standards were established as universal EU standards in order to facilitate EU directives. These standards were merged with the international IEC standards and henceforth reflect the standards in all countries. Also, the CE markings show that products conform to EC directives, and guarantee the free flow of products within the EC.

An abbreviation of Norme Europeenne (in French), and called European Standards in English. Approval is by vote among the CEN/CENELEC member countries, and is a unified standards limited to EU member countries, but the contents conform to the international ISO/IEC standards. If the relevant EN standard does not exist, it is necessary to obtain approval based on the relevant IEC standard or, if the relevant IEC standard does not exist, the relevant standard from each country, such as VDE, BS, SEMKO, and so forth. Appropriate EC directives for control equipment products The main EC directives that are to do with machinery and electrical equipment are the machinery directive, the EMC directive, the low voltage directive, and the telecom directive. Although these directives have already been issued, the date of their enactment is different for each one. The machinery directive was 1 January 1995. The EMC directive was 1 January 1996, and the low voltage directive was enacted from 1 January 1997. The telecom directive was established by the separate CTR (Common Technology References.) 187
