1.Trigger/Status Port Pin Identification

All signals are of low voltage and current. DO NOT MISS WIRE or damage may occur.

A.(+) Requires a minimum of 5 - 24V DC to activate the module with 5mA of current. Note: The DCV can be supplied from any source. The EVS protection requires the ECS-6RM for operation.

B.G = Circuit Ground, Must be of the same circuit as the DCV source.

C.V = AC Voltage Status Signal, This signal reports back to the ECS-6RM the Incoming AC Mains Voltage to the ECM module.

D.A = AC Current Status Signal, This signal reports back to the ECS-6RM the AC Mains Current draw at the ECM module. Note: Not available on ECM-20 type module.

E.D = Fault Status Signal, reports to the ECS-6RM fault conditions of a ECM module.

2.External Trigger/Manual On Switch

The ECM-20SH and ECM-20 have a manual override switch allowing them to be used as a local Power Conditioner and Surge Suppressor. For it to be remotely monitored and activated the switch must be in the “External Trigger” position.

3.Incoming AC LED

This LED will illuminate Red when the ECM has incoming AC power present at the module. This LED must be On to operate. Note: If this LED is not illuminated check the following: 1) The unit is plugged in, 2) The AC Mains Breaker feeding the AC leg to the ECM module is Off, 3) The internal fuse has been damaged. This should only be inspected by an authorized technician.

4.Active LED

This LED will illuminate Green when the ECM module has sensed the proper DCV to trigger activate the power On circuit. Note: If connected to the ECS-6RM and the EVS circuit is activated this LED will not be on. The Channel Status LED on the ECS-6RM will flash, indicating a problem, and will not turn the ECM module On until the AC Mains voltage is stable.

5.AC Fault LED

This LED will illuminate Red if damage to the Spike Suppression circuit occurs. This LED will not turn Off until repaired. Have the ECM module inspected by a qualified technician. Note: Not available on ECM-20 module.

6.AC Mains Outlet

Two 120V AC 15A outlets.
