ETA-20SH
AC Power Conditioning & Suppression Module
Issue2:ACFaultLEDisFlashingontheECM.
PossibleCause 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.
ActionNeeded 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.
Issue3:UnitissettoExternalTrigger,theincomingACLEDisilluminatedbuttheActiveLEDisnotilluminated.
PossibleCause#1 External DCV from the ETA-ECS6RM is not connected across the “+” and “G” terminals of the ECM module.
PossibleCause#2 External DCV voltage polarity is not correct across the “+” and “G” terminals.
PossibleCause#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.
Issue4:ECMActiveLEDisnotilluminated,IncomingLEDisilluminatedbuttheAbnormalLEDontheETA-ECS6RMdisplayis
flashing“OL”andtheETA-ECS6RMChannelthatisactivatingtheECMmoduleStatusLEDisFlashing.
PossibleCause The AC Mains Voltage exceeded 127VAC or the voltage dropped below 107VAC activating the “EVS”
shutdown.
ActionNeeded 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.
Issue5:ETA-ECS6RMChannelActivationStatusLEDisflashingandACpowerattheECMmoduleisactive.
PossibleCause The AC Mains Voltage at the ECM Module reached between 127-132VAC or the voltage dropped between
107-101VAC.
ActionNeeded 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.
Issue6:NoVoltageReadingattheETA-ECS6RM.
PossibleCause#1 Check Issues 1 - 4 first.
PossibleCause#2 Proper Channel is not selected for viewing.
PossibleCause#3 Channel Activation LED is Illuminated Green but the Voltage display is not on. Check the wiring between the
ETA-ECS6RM Channel and the ECM module. “V”, “A” and “D” must be in the correct polarity.
Issue7:NoCurrentReadingattheETA-ECS6RM,meterreads‘nA’.
PossibleCause#1 An ETA-ECM20 Module is connected. This module does not support current read out.
PossibleCause#2 Check Issues 1 - 4 first.
PossibleCause#3 Current Draw of ECM Module must exceed 500mA to register.
PossibleCause#4 Proper Channel is not selected for viewing.
PossibleCause#5 Channel Activation LED is Illuminated Green but the Current display reads “nA”. Check the wiring between
the ETA-ECS6RM Channel and the ECM module. “V”, “A” and “D” must be in the correct polarity.
