LOCKOUT RELAY

SPECIFICATIONS

Input

•Voltage: 18-30 VAC

•Frequency: 50-60 Hz

Output

• Relay: SPDT

• RelayContacts: 2 amps maximum

@ 30 VAC resistive

• PowerConsumption:

2 watts maximum during lockout

MODE OF OPERATION

Upon application of power with the safety

switches closed, the load will energize. If any of

the safety switches open for longer than

600 ms, the fault light will come on and the load

will stay de-energized regardless of the state

of the safety switches. Power must then be

removed for 100 ms and safety switches must

be closed in order to reenergize the load, upon

which the fault light will be off.

INSTALLATION

1. Disconnect power.

2. Connect terminals as shown in the wiring diagram below.

3. Reapply power, check operation.
