2.3 LED Status indication
Flashing
All PXR trip units have a
Status
LED for indicating the device status.
During normal operation, this indicator will flash green (approximately once
per second) to indicate that the trip unit is operating normally.
The
Status
LED will flash red if the trip unit has detected an internal fault.
This could be a problem with the trip actuator or trip unit, as well as firmware
error or a calibration error. In this case, immediate action must be taken to
remedy the fault and/or replace the unit.
LED does not light up
If the status indicator does not light up, either no auxiliary power is available,
or the trip unit’s primary supply is insufficient. This therefore does not
constitute a malfunction. The
Status
LED will flash again if the auxiliary
power supply is activated, or if the load on the circuit breaker rises to a level
greater than 15 %.
