ETA-ECS6RM

Electrical Control Sequencer

TROUBLESHOOTING

Note: All troubleshooting should be done by a certified electrician.

Issue 1 – ECM Module Incoming AC LED is not illuminated.

Possible Cause #1	Incoming AC mains circuit breaker has tripped due to excessive load.
Action Needed	Check the AC outlet that the ETA-ECS6RM is plugged into for proper voltage. If no voltage is present check
	to see if the AC outlet is on a GFI, check to see if it was tripped. If it has not been tripped trace the AC
	Mains outlet back to the electrical panel and check the AC Mains breaker to see if it is tripped.
Possible Cause #2	AC mains power is OK (120V), internal 15A (ETA-15SH) and 20A (ETA-ECM20, ETA-ECM20M, ETA- 20SH)
	Slow Blow fuse is blown.
Action Needed	Open ECM unit and replace the fuse with a Slow Blow type.
Issue 2 – ECM module AC Fault LED is Illuminated on the ECM
Possible Cause	Although the Clamping Suppression circuit virtually assures protection from most transient voltage spikes
	and surges, nature has a way of occasionally creating electrical forces that are beyond the capabilities of
	any device to absorb without some degree of damage. In the rare instance that this occurs, the clamping
	circuit has been damaged during the suppression.
Action Needed	The unit will need to be repaired or replaced. It is important to have all equipment that was connected to
	that AC Mains Line be inspected for proper operation.
	Note: The unit will still operate but no AC Spike or Suppression protection will be available.

Issue 3 – ECM module is set External Trigger, the Incoming AC LED is Illuminated but the Active LED is not Illuminated.

Possible Cause #1 External DCV from the ETA-ECS6RM is not connected across the “+” and “G” terminals of the ECM module.

Possible Cause #2 External DCV voltage polarity is not correct across the “+” and “G” terminals.

Possible Cause #3 External DCV voltage is too low to activate the trigger circuit. Must be a minimum of 5VDC to activate the ECM module. Possible short in the wiring system.

Issue 4 – ECM Active LED is not illuminated but the Incoming LED is. The Abnormal LED on the ETA-ECS6RM voltage display is flashing “OL” and the ETA-ECS6RM Channel that is activating the ECM module Green Status LED is Flashing.

Possible Cause	The AC Mains Voltage was between 101VAC and 107VAC or 127VAC and 132VAC activating the “EVS”
	shutdown.
Action Needed	The ETA-ECS6RM must be re-sequenced to reset the circuit. Measure the AC mains before the ECM
	module. If the voltage is between 117VAC and 123VAC you may proceed to reset the ETA-ECS6RM by
	restarting the start up sequence.
	Note: It is important to have all equipment that was connected to that AC Mains Line inspected for proper
	operation. If the problem persists, contact your local power company for the cause of unstable AC line
	conditions.
