Check for Welded Contacts in Overload Relay
Disconnect power from device and control wiring from the
terminals of the relay. Connect the bell set or resistance-
measuring instrument across the relay terminals. Depress
and release the reset arm to ensure the relay is reset. In this
condition there should be continuity between the terminals.
In the tripped condition, the circuit between the terminals
should be open indicating the contacts are operating
normally. Remove the bell set or resistance measuring
apparatus, rewire the relay terminals and reset the relay for
normal operation.
For further technical details on overload relays, refer to
installation instructions GEH-6237A.
