Wow FUSED 5A SB 250VAC Status LEDs relay states and override switches There are eight status LEDs one for each output point A status LED represents the state of the point s relay and not necessarily the state of the device wired to that point If the LED is ON the relay is energized With the LED ON then a device wired through normally closed NC contacts is OFF because the normally closed contacts are open Refrigeration compressors for example are wired through normally closed NC contacts so that if power to the control system fails and all the relays are de energized the control circuits for the compressors will be closed and the compressors will run Override switches have logic in line with that of the status LEDs When an override switch is put in the ON position the corresponding relay is continuously energized the LED will come ON and any device wired through the normally closed NC contacts is forced OFF If the same point were to have a device wired through it s normally open NO contacts instead the LED would be ON and the device forced ON When an override switch is put in the OFF position the corresponding relay is continuously de energized the LED will be OFF and any device wired through the normally closed NC contacts is forced ON If the same point were to have a device wired through it s normally open NO contacts isntead the LED would be OFF and the device forced OFF AK2 Input Outp
