Battery Connections 3-V battery Keep the wiring between the H7E@-N@P and R2 or C as short as possible (within 50 mm). H7E@-N@P Backup Circuit for Protection Against Power Failure When designing a circuit, keep the power wiring connections shorter than 50 mm. Refer to the connection diagram above for the proper wiring polarity. H7E@-N@P The life expectancy of a battery power supply can be calculated by the following formula: 3-V battery t = A/lc Where, t: Life expectancy of battery (h) A: Battery capacity (mAh) lc: H7E@-N@P current consumption (mA) Backup circuit Use a diode (D) having a forward voltage as small as possible (0.1 V max. at IF of 20 µA). Example: Battery life when using a 3-V lithium battery with a capacity of 1,200 mAh for the H7E@-N@P. t = 1,200 [mAh]/20 × 10-3 [mA] = 60,000 hours (approx. 6.8 years) The battery capacity varies depending on the type of battery used; oxidized silver, mercury, or lithium battery. Determine the ratio of R1 to R2 in accordance with the forward voltage of the diode to be used. Be aware that when the power supplied to the H7E@-N@P has dropped to less than the voltage of the backup circuit, the battery will discharge. To protect the circuit against a momentary power failure, an aluminum electrolyte capacitor can be used in place of a battery, as shown below: Voltage Division of Power Supply Circuit H7E@-N@P When necessary, the voltage from the battery may be divided by resistances: Backup circuit H7E@-N@P When a capacitor is used, its backup time can be calculated by the following formula: t = C (V1 - V2) / Ic When doing so, however, ensure that the following equation balances: E (V) × R2 / (R1 + R2) = 3 V R E Where, t: Backup time (s) C: Capacitance (µF) V1: Supply voltage before power failure (V) V2: Minimum operating voltage of H7E@-N@P (V) Ic: H7E@-N@P current consumption (µA) R1 2 kΩ 9.1 kΩ 33 kΩ Example: Backup time by an aluminum electrolytic capacitor of 100 µF. (Minimum operating voltage of H7E@-N@P is 2.6 V.)

Do not use the Counter in the following places: • Locations subject to direct sunlight. • Locations subject to corrosive gases. • Locations subject to dust. Do not use any battery other than the specified one (Y92S-36). Using another battery may cause liquid leakage or breakage, resulting in malfunction or injury. Before Use Reset Input and Count/Timer Input • An insulation sheet has been inserted to maintain the quality of the Totalizer in the event of a long period without use. Be sure to remove this sheet before attempting to use the product. Remove the insulation sheet and press the Reset Key on the front panel of the Counter. (With the H7ER-N,-NV(-H),-NV1(-H), models, “0” or “0.0” will be displayed after 1 s.) • The H7E operates using its built-in Battery. If the H7E is connected to a device that has +V and OUT terminals that are connected with a diode as shown in the circuit diagram, the circuit indicated by the arrow 1 or 2 will be formed when the device is turned OFF. As a result, the H7E may be reset or count by one. It is recommended that such devices not be connected to the H7E. Devices Insulation Sheet Internal circuit H7E@-N Count/Timer input or reset input Reset Key • Switch settings on the Counter must be performed before mounting it to a control panel. • Do not use the Counter in the following locations: • Locations subject to severe changes in temperature. • If an excessive voltage is applied to the count/timer input or reset input terminals, the internal elements may be damaged. Ensure that the following voltages are not exceeded: • PNP/NPN universal voltage input model: 30 VDC • Locations subject to condensation as the result of high humidity. • AC/DC voltage input model: At count/timer input: 240 VAC (peak voltage: 338V) 240 VDC At reset input: No voltage can be applied. (No-voltage input) • No-voltage input model: No voltage can be applied. Mounting Precautions for Flush Mounting Although the operating section is watertight (conforming to NEMA4, IP66), rubber packing is provided to avoid water leakage through the gap between the Counter and panel cutout. Unless this rubber packing is tightly squeezed on, water may permeate inside the panel. Therefore, be sure to tighten the screws for fixing the Y92F-34 Flush Mounting Bracket. (Excessive tightening may also deform the rubber packing.) Screw for the Flush Mounting Bracket The wider side must face the panel. • Avoid wiring close to high-tension or large-current lines. • Do not remove the outer case when voltage is being applied to the power supply terminals or the input terminals. • The input for the H7E@-NFV-@ is a high-impedance circuit and so influence from an induced voltage may result in malfunction. Therefore, when the input signal wiring is longer than 10 m (line capacitance of 120 pF/m, at room temperature), it is recommended that a CR filter or a bleeder resistor is connected. Y92F-34 Adapter Panel Self-powered Totalizer New H7E (Common) C-37 Counters !WARNING This product has a built-in lithium battery. Do not short-circuit the + and − terminals, charge, disassemble, deform, or expose the battery to fire. The battery may explode (break), catch fire, or cause liquid leakage. Count Input, Timer Input or Reset Input to More than One H7E Counter at a Time AC/DC Multi-voltage Input Models • When connecting count/timer input from an SSR to the Counter that operates with AC/DC voltage input, use OMRON’s G3TA-IA/ID SSR (for DC) whose leakage current is 0.1 mA max. or connect a bleeder resistor in parallel to the input circuit of the Counter. • PNP/NPN Universal DC Voltage Input or Leakage current: 0.1 mA max. or or or *Bleeder resistor The voltage between terminals 1 and 2 must be 1.5 V maximum when the SSR is OFF. Backlight Power Supply • To reduce variation in the brightness of the backlight when using more than one H7E with a backlight, use the same power supply for all the backlights. or Note: H (Reset ON) level must be 4.5 V minimum. 4.7 (kΩ)/N + V 4.7 (kΩ)/N + R • No-voltage Input H= • When connecting the DC power supply for the backlights, be sure to connect the polarities correctly. or Note: 1. The leakage current of the transistor used for input must be less than 1 µA. 2. The forward voltage of the diode must be as low as possible (i.e., 0.1 V maximum with an IF of 20 µA) so that the voltage between terminals 3 and 4 will be 0.5 V when the reset input is ON. Input and Power Supply No-voltage Input Models • Do not impose voltage on the Counter if the Counter is a model that operates with no-voltage input, otherwise the internal circuit of the Counter may be damaged. Do not connect any single input signal in parallel to Counter models operating with no-voltage input and those operating with voltage input, otherwise the Counters may malfunction. • When connecting a sensor to the Counter that operates with novoltage input, make sure that the sensor has open collector output. Input Verification with the H7ET Time Counter (When the time range is not set to 0s to 999h59min59s) The decimal point of the LCD blinks every other second while an input signal is being applied. If the decimal point is not blinking, the input signal is not being received correctly. Check the input signal connections. Unit Label for Time Counter and Tachometer A unit label has been packed with the Counter. Use in accordance with the application. Sensor Battery Replacement Remove the wiring when replacing the Battery. Do not come in contact with any item to which high voltage is being applied. Doing so may result in electric shock. • When connecting an open collector input from a transistor to the Counter that operates with no-voltage input, make sure that the leakage current of the transistor is 1 µA maximum. Before changing the Battery, the person should ensure that they are not carrying any static electric charge. No-voltage Input and PNP/NPN Universal DC Voltage Input Models 1. Using the tool, pry open the lift-tab on the case. (1) 2. Pull the body out of its outer case. (2) 3. Lift the Battery up by the edge and remove it. (3) When removing the Battery, do not come in contact with the display area or any internal parts. 4. Wipe the back of the new Battery before inserting it. 5. Ensure that the + and - terminals are correctly oriented. 6. After replacing the Battery, re-insert the body into its case. (4) Check that the case is securely held in by the lift-tab. • The operation of the Counter may be affected if the capacitance of input lines exceeds 500 pF (about 10 m, with parallel wires of 2 x 2 mm). Keep all wires as short as possible. When using shielded wire, line capacitance may occur. C-38 Self-powered Totalizer New Procedure for replacing the Battery (refer to the diagrams below): H7E (Common) 7. Press the Reset Key before use (not necessary for H7ER-N,-NV,NV1). (5) The count or timer input, reset input, and backlight power supply terminals of the no-voltage input or PNP/NPN universal DC voltage input models (H7E@-N,-N1, H7E@-NV(-H),-NV1(-H)) are not isolated. (2) A SELV power supply conforming to Appendix H of IEC61010-1 should be used for the count or timer input, reset input and backlight power supply terminals. A SELV power supply is a power supply for which the input and output have double or reinforced insulation, and for which the output voltage is 30 Vrms with 42.4 V peak or 60 VDC max. (Only the H7E@-NV@-H has a backlight.) Recommended 24VDC power supply; eg. OMRON S8VS. (1) Battery (3) The terminals for count or timer input and reset input for AC/DC multi-voltage input models have basic insulation. Connect the reset input terminals to a device that does not have exposed current-carrying parts and has basic insulation for 240 VAC. (4) Others If the indicator keeps flickering or is OFF, the internal battery may be close to the end of its service life. In such a case, it is suggested that the battery be replaced. (5) ■ PCB-mounting Counter Power Supply Battery Replacement • Use the power supply within the applicable range indicated by the following waveform, while considering the ripple and voltage fluctuations of the circuit power source. To prevent unwanted reset when replacing the battery, connect the new battery before disconnecting the old one. Otherwise, the voltage supplied to the counter circuit drops, causing the present count value to reset. 3.6 V Voltage When designing the circuit board, providing two extra terminals for battery connection will make the switch must simpler.

Battery life guideline 0 Self-powered Totalizer New H7E (Common) C-39 Counters Tool (1) EN/IEC Standards Inputs PC Board (Bad Example) Do not route the wiring of the count, timer, or reset inputs in the vicinity of, or in parallel to the wiring of high-voltage or inductive load circuits (such as motors and relays). Also, keep the wiring as short as possible. PC Board (Good Example) H7E@-N@P Large-currentconsuming components Placed far away from the power supply. Large-currentconsuming components Wired in parallel with large-currentcarrying components. H7E@-N@P Bypass capacitor H7E@-N@P Power supply Be careful not to apply voltages exceeding the following values to the count, timer, or reset terminals, otherwise the internal circuit may be damaged. Bypass capacitor Power supply When using the Counter in an environment where the Counter is subject to frequent occurrences of vibration or shock, or when mounting the Counter facing downwards or sideways, it is suggested that the Counter be directly soldered to a PCB instead of using sockets. To Conform to EN/IEC Standards No-voltage input: 3 VDC Since the Counter is not flux-tight, do not use flux when soldering. Input terminals have no insulation from power supply terminals. The power supply terminals must be supplied from a SELV source in accordance with IEC61010-1 Annex H. SELV (separated extra-low voltage) source is a power supply having double or reinforced insulation between the primary and the secondary circuit and having output voltage of 30 V rms max. and 42.4 V peak max. or 60 VDC max. Avoid automatic and dip soldering. Manually solder the Counter onto a PC board, and avoid cleaning as much as possible. Cleaning When mounting the Counter on a PC board with components which consume higher current than the H7E@-N@P, observe the following precautions.
