Be aware that the application of voltage that exceeds the voltage range of the H level to the count input terminal, and the application of voltage to the reset input terminal, can cause damage to the internal elements. Explanation of operation 1. Counting takes place when the count input signal is ON. 2. Counting resumes again when the count value reaches 99999999 (full scale value) and then returns to “0” with a new count input. 3. No measurement takes place when a reset is input. 1) When reset is ON, resetting takes place and the count becomes “0”. 2) Press the front reset button when you want to reset manually (only panel installation type). Count input ❇ Reset input Count value 0 1 99999999 0 1 0 1 Note) ❇Count becomes “1” when the reset input is turned OFF while the count signal is being input. Note) Be aware that battery life will decrease if the count input or reset input are left ON. Cautions for use 1. Non-voltage input type For both panel mounting and PC board mounting types 1) Never apply voltage to the non-voltage input type. This will damage the internal elements. Also, since there is a possibility of erroneous operation, do not connect in parallel the inputs of a non-voltage input type and another counter from a single input signal. 2) Since the current flow is very small from the count input and reset input terminals (1 and 3 on the panel mounting type and terminals e to t and S to F on the PC board mounting type) please use relays and switches with high contact reliability. 3) When inputting with an open collector of a transistor, use a transistor for small signals in which ICBO is 1 µA or less and always input with no voltage. 4) When wiring, try to keep all the input lines to the count and reset inputs as short as possible and avoid running them together with high voltage and power transmission lines or in a power conduit. Also, malfunctions might occur if the floating capacitance of these wires exceeds 500 pF (10 m 32.808 ft. for parallel wires of 2 mm2). When using 2 kHz mode, use with a wiring floating capacitance of 120 pF (3 m 9.843 ft. for parallel wires of 2 mm2). In particular, when using shielded wiring, be careful of the capacitance between wires. PC board mounting type 1) For external power supply use manganese dioxide or lithium batteries (CR type: 3V). 2) Always reset after external power is applied and confirm that the display reads “0”. 3) Make the wiring from the battery to the counter unit as short as absolutely possible. Also, be careful of polarity. 4) Calculate battery life with the following formula. t = A/I t: battery life [h] I: LC2H current consumption [mA] A: battery capacity until minimum operation voltage is reached [mAh] 5) Hand solder to the lead terminal. Do not dip solder. With the tip of the soldering iron at 300°C 572°F perform soldering within 3 seconds (for 30 to 60 W soldering iron). 2. Voltage input type 1) Be aware that applying more than 30 V DC to count input terminals 1 and 2, and reset input terminals 3 and 4 will cause damage to the internal elements. 2) For external resetting use H level (application of 4.5 to 30 V DC) between reset terminals 3 and 4 of the rear terminals. In this case, connect + to terminal 3 and – to terminal 4. This is the valid polarity; therefore, the counter will not work if reversed. 3) When wiring, try to keep all the input lines to the count and reset inputs as short as possible and avoid running them together with high voltage and power transmission lines or in a power conduit. Also, malfunctions might occur if the floating capacitance of these wires exceeds 500 pF (10 m 32.808 ft. for parallel wires of 2 mm2). 3. Free voltage input type 1) Use count input terminals 1 and 2 for free voltage input and reset terminals 3 and 4 for non-voltage input. 2) Be aware that the application of voltage that exceeds the voltage range of the H level to the count input terminal, and the application of voltage to the reset input terminal, can cause damage to the internal elements. 73 02/2003 LC2H.fm Seite 74 Samstag, 23. März 2002 4:15 16 LC2H 3) Since the current flow is very small from reset input terminal 3, please use relays and switches with high contact reliability. 4) When inputting a reset with an open collector of a transistor, use a transistor for small signals in which ICBO is 1 µA or less and always input with no voltage. 5) To reset externally, short reset input terminals 3 and 4 on the rear. 6) Input uses a high impedance circuit; therefore, erroneous operation may occur if the influence of induction voltage is present. If you plan to use wiring for the input signal that is 10 m or longer (wire capacitance 120 pF/m at normal temperature), we recommend the use of a CR filter or the connection of a bleeder resistor. 4. How to reset multiple panel mounting type counters all at once (input is the same for count) Non-voltage input type D D 3 4 D 3 4 Tr or 3 4 Notes) 1. Use the following as a guide for choosing transistors used for input (Tr). Leakage current < 1 µA 2. Use as small a diode (D) as possible in the forward voltage so that the voltage between terminals 3 and 4 during reset input meets the standard value (0.5 V). ( At IF = 20 µA, forward voltage 0.1 and higher.)

Waterproof construction (Installation frame type) The operation part of the panel installation type (Installation frame type) is constructed to prevent water from entering the unit and a rubber gasket is provided to prevent water from entering the gap between the unit and the panel cutout. There must be sufficient pressure applied to the rubber gasket to prevent water from entering. Be sure to use the installation reinforcement screws when installing the frame (ATH3803). Note) Make sure that H (reset ON) level is at least 4.5 V. Tool 1 Note) The one-touch installation type is not waterproof. 8. Do not use in the following environments 3 4 ganic solvents such as methyl alcohol, benzene and thinner, or strong alkali substances such as ammonia and caustic soda. 10. Cautions regarding battery replacement 1) Remove wiring before replacing the battery. You may be electrocuted if you come into contact to a part where high voltage is applied. 2) Make sure you are not carrying a static electric charge when replacing the battery. 3) Battery replacement procedure 1 One-touch installation type 1. Using a tool remove the up/down hook of the case. 2. Pull the unit away from the case. 3. Remove the battery from the side of the unit. Do not touch the display or other parts. 4. Before inserting wipe clean the surface of the battery. 5. Insert the battery with the + and – sides in the proper position. 6. After replacing the battery return the unit to the case. Verify that the hook of the case has properly engaged. 7. Before using press the reset button on the front. 2 Frame (ATH3803) 5.
