(Set detecting level 50 % when the saturation voltage is not

greater than 0.8 V, set 70 % when the saturation voltage is

between 0.8 to 1.5 V.)

130 mA (15 mA at each excitation)

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 1500 V AC @ 1 minute (input 1 to input

2 to input 3 to input 4 to internal bus or internal power)

2000 V AC @ 1 minute (power input to FG; isolated on the

power supply module)

FUNCTIONS

■ MANUAL COUNT RESET

1) Remove Network Module or its cables and interrupt

communication with other devices.

2) Turn ON the Count Reset SW.

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.

The RUN LED starts blinking at the same time.

5) After the green LED is confirmed, turn the power supply

off.

6) Turn OFF the Count Reset SW.

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.
