■ Operation and Setting Methods

Setting Ranges and Wiring Connections

Connections

1. Input

Connect the input between terminals V1-COM, V2-COM, or V3-COM, depending on the input

voltage.

Malfunctions may occur if the input is connected to unused terminals and the Unit will not operate

correctly

2. Power Supply

Connect the power supply to terminals A1 and A2.

3. Outputs

SPDT relays are output to terminals 11, 12, and 14.

Note: Use the recommended ferrules if using twisted wires.

DIP Switch Settings

The power ON lock time, resetting method, relay drive method, and operating mode are set using the DIP switch located on the bottom of the Unit.
