• The TRIP/WARN LED flashes a yellow 3-long / 13-short blink pattern
• Bit 12 in Control Warning Status (Parameter 13) sets to 1
• Bit 1 in Device Status 0 (Parameter 20) sets to 1
• Any relay outputs configured as a Warning Alarm close

Hardware Fault
The E300 relay continuously monitors the status of the Control, Sensing, and
Communication Modules. The E300 relay issues a hardware fault trip if there is
an issue with the Control, Sensing, and Communication Modules or if one of the
modules is missing or incompatible. The Hardware Fault Trip is always enabled.
