Hardware Fault
The E300 Electronic Overload Relay continuously monitors the status of the
Control, Sensing, and Communication Modules. The E300 Electronic Overload
Relay issues a hardware fault trip if there is an issue with the Control, Sensing,
and Communications Modules or if one of the modules is missing or
incompatible. The Hardware Fault Trip is always enabled.
The E300 Electronic Overload Relay trips with a hardware fault trip indication
if:
•
No trip currently exists
•
Hardware Fault Trip is enabled
•
An issue exists between the Control Module, Sensing Module, and/or
Communication Module
If the E300 Electronic Overload Relay trips on a hardware fault trip, the
following occurs:
•
The TRIP/WARN LED flashes a red 3-long / 7-short blink pattern
•
Bit 6 in Control Trip Status (Parameter 7) sets to 1
•
Bit 0 in Device Status 0 (Parameter 20) sets to 1
•
Any relay outputs configured as a Trip Relay open
•
Any relay outputs configured as a Control Relay open
•
Any relay outputs configured as a Trip Alarm close
•
Any relay outputs configured as a Normal Relay are placed in their
Protection Fault state (if so programmed)
