Panel design can be changed from standard (ash gray) to black (sold separately)
Set the input and output modes with the DIP switches on the side of the counter.

Set the set value with the UP and DOWN keys on the front of the counter.

For the input mode, you can choose one of the following five modes
Input mode | Operation | *Minimum input signal width 30 Hz: 16.7 ms; 5 kHz: 0.1 ms |
---|---|---|
Addition [UP] |
IN1 or IN2 works as an input block (gate) for the other input. | Example where IN1 is the count counting and IN2 is the input block (gate).![]() Example where IN2 is the counting input and IN1 is the input block (gate). ![]() *"A" must be more than the minimum input signal width. |
Subtraction [DOWN] |
||
Directive [DIR] |
IIN1 is the counting input and IN2 is the addition or subtraction directive input. IN2 adds at L level and subtracts at H level. | ![]() * "A" must be more than the minimum input signal width. |
Independent [IND] |
IN1 is addition input and IN2 is subtraction input. | ![]() IN1 and IN2 are completely independent, so there is no restriction on signal timing. |
Phase [PHASE] |
Addition when the IN1 phase advances beyond IN2, and subtraction when the IN2 phase advances beyond IN1. | ![]() * "B" must be more than the minimum input signal width. |
For the output mode, you can choose one of the following seven modes
Output mode | Operation | (Example when input mode is either addition or subtraction) |
---|---|---|
Maintain output Hold count [HOLD-A] |
Output control is maintained after count-up completion and until resetting. During that time, the count display does not change from that at count-up completion. | ![]() *n:Set value |
Maintain output Over count I [HOLD-B] |
Output control is maintained after count-up completion and until resetting. However, counting is possible despite completion of count-up. | ![]() *n:Set value |
Maintain output Over count II [HOLD-C] |
Output control is maintained after count-up completion and until the next signal enters. However, counting is possible despite completion of countup. | ![]() *n:Set value |
One shot Over count [SHOT-A] |
Output control is maintained after count-up completion for a fixed time (approx. 1 sec). Counting is possible despite completion of count-up. | ![]() *n:Set value |
One shot Recount I [SHOT-B] |
Output control is maintained after count-up completion for a fixed time (approx. 1 sec). Counting is possible despite completion of count-up. However, reset occurs simultaneous with completion of count-up. While output is being maintained, restarting of the count is not possible | ![]() *n:Set value |
One shot Recount II [SHOT-C] |
Output control is maintained after count-up completion for a fixed time (approx. 1 sec). Counting is possible despite completion of count-up. However, reset occurs simultaneous with output OFF. | ![]() *n:Set value |
One shot Hold count [SHOT-D] |
Output control is maintained after count-up completion for a fixed time (approx. 1 sec). During that time, the count display does not change from that at count-up completion. Reset occurs simultaneous with output OFF. | ![]() *n:Set value |
