What do the relays do when my ERP, ERP-FT, Sensor IQ, or EchoDIN loses power?
If my Echo Relay Panel (ERP), Echo Relay Panel Feedthrough (ERP-FT), Sensor IQ, or EchoDIN panel loses power, what do the relays do?
In all cases the relays are mechanically held in whatever position they existed when the rack lost power. If the relays need to be turned on or off while the rack still has no control power you can manually flip the relay state by following the instructions for each rack below:
- ERP - Flip the small black switch on the relay.
- ERP-FT - Flip the yellow switch on the relay. You may need a flat blade screw driver to help.
- SensorIQ - Turn the breaker off, and back on.
- EchoDIN - Flip the switch on the front to ON or OFF.
