Connection

Caution

1. Do not feed a voltage signal into the Contact Input and Remote Reset terminals. This may cause damage to the internal circuit of the unit.
2. Contact and Non-contact input cannot be used simultaneously. Please choose only one method of input.
3. During a power failure, the LED display will go off. At this time, the counter cannot detect input or reset signals even if signals are received.
4. Make sure to short terminals 7 and 8 to enable the memory function. When the counter will be shut down for a long period of time, disconnect terminals 7 & 8 to prevent the discharge of the internal battery. The internal battery is charged when power is supplied to the counter.
5. Simultaneous input of signals for the Add input and Subtract input is not possible. Use a multiplexer (ex. PS-41S) if such function is desired.
6. Use shielded lead wires for the Input terminal and Reset terminal. Also, make the lines from the power source as far as possible from the lines of the Input and Reset lines.
