Open Red Open
Warning Undervoltage with a CLOSE Command Present Yellow – Flashing Open/Closed  Off / Yellow  Open/Closed 
 Warnings will be cleared when a change of input state occurs, and the condition has been resolved.
 Faults require control power to be removed until the unit resets
 Flash 1 = 1 Flash Red LED followed by a pause
 Flash 2 = 2 Consecutive Red LED flashes followed by a pause
 Flash 3 = 3 Consecutive Red LED flashes followed by a pause
 Yellow – R1 = Yellow with 1 Red flash followed by a pause
 Yellow – R2 = Yellow with 2 consecutive Red flashes followed by a pause
 Yellow – R3 = Yellow with 3 consecutive Red flashes followed by a pause
 Invalid Command Types:
1. Close, Jog or Trip commands present during power up sequence
2. Close or Jog command re-applied too quickly (before contactor opening sequence is verified).
Allow at least 60 msec, plus drop out delay time, before re-applying these signals.
NOTE: Contactor will only respond to a close command re-applications after the re-start delay timer has expired.
3. Close and Trip commands present simultaneously (valid with Mechanical Latch contactors only).
 Open during undervoltage, Closed if voltage restored
 Will reflect actual status of the contactor
