Chapter 11 Troubleshooting
section of this chapter for tips associated with troubleshooting trip and warning
conditions. A listing of these codes can be found on the side of the EC4 Current
Monitoring Relay in addition to the table below.
Network Status LED
This LED provides information on the state of the EC4 Current Monitoring
Relay’s DeviceNet network connection. Refer to the DeviceNet Troubleshooting
Procedure
section for descriptions of the various states this LED can take and the
associated recommended corrective action.
OUT A & OUT B LEDs
The amber OUT A or OUT B LED illuminates when the output is commanded
on. However, an illuminated LED does not guarantee that the output is actually
on.

IMPORTANT
The Trip conditions identified as “Protection Faults” are the basis for
the OUTA Pr FltState, OUTA Pr FltValue, OUTB Pr FltState, and OUTB Pr
FltValue parameters.
IMPORTANT
Cycling power to the EC4 Current Monitoring Relay will not clear a
“Non-Volatile Fault”. A “Non-Volatile Fault” must be manually reset.
An Overload or PTC Fault can also be automatically reset.
