When using contact input, since current flow is small from 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. 2.

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 300C 572F perform soldering within 3 seconds (for 30 to 60 W soldering iron). 2.

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. Note) Count becomes "1" when the reset input is turned OFF while the count signal is being input. 0 Notes) 1. Do not reverse the polarities when connecting the DC voltage for the backlight. 2. 2 and 4. (The input and reset circuits are functionally insulated.) 3. When using transistor (Tr) input, use the right as a guide. (Collector withstand voltage Q 50 V, leakage current < 1 A) 4. 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). 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 A 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 07/2004 LC2H 3 4 D 3 4 D 3 4 Tr or 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 A 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 3 4 R Tr +V or 3 4 +V Notes) 1. Use the following as a guide for choosing transistors used for input (Tr). Leakage current < 1 A 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 A, forward voltage 0.1 and higher.) 3 4 Voltage input type 3 4 Note) Make sure that H (reset ON) level is at least 4.5 V. 2 5 2 5 2 6 Red 2 6 24V DC 5.

Insulation sheet Before using a panel mounting type, please pull and remove the insulation sheet from the side of the product in the direction of the arrow. In consideration that the product might be stored for long periods without being used, an insulation sheet is inserted before shipping. Remove the insulation sheet and press the front reset button. 78 07/2004
