PANEL FEATURES

T rigger / Status Port Pin Identification - All signals are of low voltage and current.

Note: All data signals are low voltage under 5V. DO NOT MISWIRE or damage may occur.

(+) 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.

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

AC Voltage Status Signal, this signal reports back to the ETA-ECS6RM the Incoming AC Mains Voltage to the ECM module.

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

Fault Status Signal, reports to the ETA-ECS6RM fault conditions of an ECM module.

E xternal Trigger / Manual On Switch – The ETA-20SH has a manual override switch allowing it 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.

I ncoming 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 illuminating check the following: 1) The unit is plugged in, 2) The AC Mains Breaker

feeding the AC leg to the ECM module is On, 3) The internal fuse has been damaged, this should only be inspected by an

authorized technician.

A ctive LED – This LED will illuminate Green when the ECM module Manual Switch is in the ON position or the trigger circuit has

sensed the proper DCV to 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.

A C Fault LED – If damage to the Spike Suppression circuit occurred this LED will illuminate Red. This LED will not turn Off until

repaired.

AC Mains Outlet – Two 120V AC 20A outlets.

AC Mains Power Cord – 9' (3m), 12-gauge
