ETA-ECM20 & ETA-ECM20M MODULE PANEL FEATURES

Trigger / Status Port Pin Identification – all signals are of low voltage and current. DO NOT MISWIRE 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 ETA-ECS6RM 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 ETA-ECS6RM the Incoming AC Mains Voltage to the ECM

module.

D. A = AC Current Status Signal, this signal reports back to the ETA-ECS6RM the AC Mains Current draw at the ECM module.

Note: Not available on ETA-ECM20 type module.

E. D = Fault Status Signal, reports to the ETA-ECS6RM fault conditions of a ECM module.

External Trigger / Manual On Switch – The ETA-20SH and ETA-ECM20 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.

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.

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 ETA-ECS6RM and the EVS circuit is activated this LED will not be on. The Channel Status LED on

the ETA-ECS6RM will flash indicating a problem and will not turn the ECM module ON until the AC Mains voltage is stable.

AC Fault LED – If damage to the Spike Suppression circuit occurred this LED will illuminate RED. This LED will not turn OFF until

repaired. Have the ECM module inspected by a qualified technician. Note: Not available on ETA-ECM20 type module.

6. AC Mains Outlet – Two 120V AC 15A outlets.
