The electrical system comprises:
-Isolation control unit inhibition switch
-Stow switches — two per door, signal feedback to the FADEC
-Deploy switch — one per door, signal feedback to the FADEC
-Maintenance test switch — allows thrust reverser operation without engine operating

18-01-20 THRUST REVERSER SYSTEM (Cont) REVERSE THRUST OPERATION

When reverse thrust is desired, the thrust levers are drawn aft to the IDLE position, where the thrust reverser levers may be lifted, thus allowing the main thrust levers to be pulled further rearward to the REV soft detent. This rearward movement signals the FADEC (via the RVDTs) and the thrust reversers (via the microswitches in the TQA) that thrust reverser de-ployment has been commanded. Once in the REV detent, it is unnecessary to hold the thrust reverse levers up, as they stay in place until the pilot selects forward operation. Interlock balks will prevent movement of the levers rearward beyond REV until the thrust reverser deploy switches provide feedback that the thrust reverser doors are fully deployed. During the de-ployment sequence, a white REV icon is displayed on the EICAS, and N1 target and bug are removed from the display. Once the doors are fully deployed, the REV icon changes to a green color, and the interlock baulk is released. This will allow for thrust lever modulation between the REV and MAX REV positions. N1 target and bug are set to the maximum reverser N1 setting.
To stow the thrust reversers, the main thrust levers are moved forward to the IDLE position. As the lever move between the REV and IDLE positions, the thrust reverser levers will return to their forward thrust position. Interlock balks will pre-vent movement of the main thrust levers forward beyond IDLE until the thrust reverser stow switches provide feedback that the doors have completely closed. During the stow phase, the REV icon will go from green to white, and the N1 target and bug are removed from the display. Once the doors are fully stowed, the REV icon will disappear, and the N1 target and bug will reset to the takeoff setting. Also, the forward interlock baulk will be removed, allowing for forward thrust modulation above idle thrust.
