TROUBLESHOOTINGTHEECMMODULEWITHANETA-ECS6RM
Note: All troubleshooting should be done by a certified electrician.
Issue1:IncomingACLEDontheECM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-20SH is plugged into for 120V AC voltage. If no voltage is present, check to
see if the AC outlet is on a GFI and 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 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:ACFaultLEDisFlashing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 can be
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
ETA-ECM20 Module inspected for proper operation.
Note:TheunitwillstilloperatebutnoACSpikeorSuppressionprotectionwillbeavailable.
Issue3:Unitissetto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,IncomingLEDisilluminatedbuttheAbnormalLEDontheETA-ECS6RMdisplayis
flashing“OL”andtheETA-ECS6RMChannelthatisactivatingtheECMmoduleStatusLEDisFlashing.
PossibleCause The AC Mains Voltage exceeded 127VAC or the voltage dropped below 107VAC activating the “EVS”
shutdown.
ActionNeeded The ETA-ECS6RM must be re-sequenced to turn off the reset circuit, measure the AC mains before restarting
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ETA-ECM20Modulebeinspectedfor
proper operation. If the problem persists, contact your local power company for the cause of unstable AC line
conditions.
Issue5:ETA-ECS6RMChannelActivationStatusLEDisflashingandACpowerattheECMmoduleisactive.
PossibleCause The AC Mains Voltage at the ECM Module reached between 127-132VAC or the voltage dropped between
107-101VAC.
ActionNeeded The ETA-ECS6RM must be re-sequenced to turn off the LED, measure the AC mains before restarting 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themoduleinspectedforproperoperation.If
the problem persists, contact your local power company for the cause of unstable AC line conditions.
