Contactor Feedback Warning
The E300 relay provides a Contactor Feedback warning indication if:
• No trip currently exists
• The Operating Mode program does not receive a contactor feedback
signa
l before the Feedback Timeout (Parameter 213)
If the E300 relay warns on a Contactor Feedback, the following occurs:
• The TRIP/WARN LED flashes a yellow 3-long / 10-short blink pattern
• Bit 9 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 closes
