Operation Methods
Setting Ranges and Wiring Connections
Connections
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.
Power Supply
Connect the power supply to terminals A1 and A2.
Outputs
For a relay output, the SPDT contacts are output on terminals 11, 12, and 14. For a transistor output,
the NPN output is on terminals 11 and 14.
Do not use the transistor output for control applications. It is designed only to output a signal when
an error is detected.
DIP Switch Settings
The power ON lock time, resetting method and operating mode are set using the DIP switch located on the front of the Unit.
Note: Open the DIP switch cover to set the DIP switch.
Keep the DIP switch cover closed while the power supply to the Relay is ON.
