Fault codes
fault code consists of a red number 1 (one), and
a green, one to three digit code number. When
a fault is detected the fault code should be
recorded for further use when the relay module
is to be repaired.
Some of the fault codes that may appear on the
display of the sensitive earth-fault relay module
SPCJ 1C7 are shown in the following list:
Shortly after the self-supervision system has
detected a permanent internal fault in the relay
module the red IRF (Internal Relay Fault) indi-
cator is lit. Simultaneously the relay module
generates a control signal to the IRF output
relay.
In most fault situations an autodiagnostic fault
code appears on the display of the module. The
