(ON/OFF time ≥ 5 msec.)

This unit is designed to be able to accept a frequency up to

100 Hz, however,‘chattering’ contact must be avoided for

accurate measuring of such high frequency. Use mercury

relays or similar ones that do not cause any chattering.

Totalized pulse range: 0 - 9999999

Count at overflow: Reset and restart at ‘0.’(Max. pulse

range selectable from 10000 to 2147483647 using the

R3CON PC Configurator Software. ‘0’ or ‘1’ from which

restart counting at overflow is pre-settable. Refer to the

R3CON Users Manual for detailed information.)

COUNT RESET

There are three different ways to reset count value.

■ COUNT RESET WITH DIP SW

1) Remove Network Module or its cables and interrupt

communication with other devices.

2) Turn ON the Count Reset SW (DIP SW3-1) on R3S-PA8

module.

3) Return the module to the base and turn the power supply

on.

4) ERR LED turns on and the module starts resetting its

counter. When the resetting is complete, the LED turns to

green. DO NOT remove the power while the red LED is on.

5) After confirming that ERR LED is green, turn the power

supply off.

6) Turn OFF the Count Reset SW (DIP SW3-1).

7) Return the Network module onto the base and turn the

power supply on.

Note: Count Reset SW must be turned OFF after this

procedure because the module does not start counting with

ON state. Even when the count overflow set value is 1, the

counter is reset to 0.

■ COUNT RESET WITH RESET SIGNAL

With the Count Reset Input SW (DIP SW3-3) turned ON, the

count reset signal value becomes effective.

SW3-3 = OFF: invalid

SW3-3 = ON: valid

One pulse supplied at the Count reset input terminal will be

recognized as a reset signal.

1) ERR LED turns on (red color) when the reset signal is

received.

2) In 1 second, the module starts resetting its counter.

When the resetting is complete, the LED turns to green.

3) After 1 second, ERR LED turns back to the state before

the reset signal has been received.

Note: Reset signals received while the module is processing

(1) through (3) are ignored. Even when the count overflow

set value is 1, the counter is reset to 0.

■ COUNT RESET FROM HOST PC/PLC

Refer to “COUNTER SETTING FROM HOST PC/PLC” section

hereafter.
