ECM-15SH
AC
Power Conditioner & Suppression Module
1601 Jack McKay Blvd. • Ennis, Texas 75119 U.S.A.
Telephone: [phone] • Fax: [phone]
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 ECS-3 is not connected across the “+” and “G” terminals.
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 ECS-3 is flashing.
Possible Cause: The AC Mains Voltage exceeded 127VAC or the voltage dropped below 107VAC activating the “EVS” shutdown.
Action Needed: The ECS-3 must be re-sequenced to turn off the LED, measure the AC mains before restarting the ECS-3. If the
voltage is between 117VAC and 123VAC you may proceed to reset the ECS-3 by restarting the start up sequence.

Troubleshooting the ECM Module with an ECS-6RM
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 ECM-15SH 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 15A (ECM-15SH) 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 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 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 AC
Mains Line inspected for proper operation.
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 ECS-6RM 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 ECS-6RM display is
flashing “OL” and the ECS-6RM 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 ECS-6RM must be resequenced to turn off the reset the circuit, measure the AC mains before restarting the
ECM module. If the voltage is between 117VAC and 123VAC you may proceed to reset the ECS-6RM by
