Electrical Control Sequencer
ETA-ECM20 20A AC Control Module (No Current Monitoring)
The ETA-ECM20 does not support the same Current monitoring or EMI/RFI Filter feature as the ETA-ECM20M, ETA-20SH and the ETA-15SH models have. However, it does support AC Spike and Surge Suppression, AC Mains Voltage monitoring, EVS circuitry and Remote Activation.
In certain applications ETA Systems suggests using an ETA-ECM20 Module vs. an ETA-ECM20M in places where some of the features would be redundant because of the electrical location of the ECM module. This would be a cost savings to use a less expensive ECM module where redundant circuitry is not needed.
Example: One 20A Incoming AC line, Two sequenced AC outlets are required, use one ETA-ECM20M and one ETA-ECM20 module
wired in parallel. Explanation: If the AC Mains system required a sequenced outlet and did not require more than 20A of service for a portion of the AC power system, an ETA-ECM20M module can be placed in parallel with an ETA-ECM20M module. It is not necessary to have Amperage readings from both ECM Modules because you can read the current from the ETA-ECM20M Module which could be in parallel with an ETA-ECM20 Module which is on the same incoming AC line as the ETA-ECM20M module. They would have the same current reading because they are in parallel. Also, the EMI and RF filtering are across the same AC line leg, so both ECM Modules connected to that line are filtered, no need to have redundant filtering. Note: In this wiring configuration you still get the Voltage monitoring to see if the module is active and have extra surge protection. See ECM Module wiring configurations.
ECS-KSW6
The ETA‑ECS6 can be remotely activated with each channel being monitored by using the Atlas Power ECS-KSW6 control panel available through ETA Systems. This panel can be placed several hundred feet away from the ETA‑ECS6 controller. A Keyed On
/Off switch is provided for security. There are six Bi-Color LEDs on the ECS-KSW6 panel. One LED for each of the six sequenced channels of the ETA‑ECS6. These LEDs mimic the Channel Activation LEDs that are on the front of the ETA‑ECS6 panel. Please refer to that section for complete details. Wiring the ECS-KSW6 panel requires a RJ45 connector and 8 conductors. Note: This is not an IP Ethernet port and is only used for connectivity between ETA‑ECS6 and the ECS-KSW6 units. Wiring of this connector is the same as an Ethernet cable. Do not mis wire the connector or damage may occur.
