2800

Auxiliary shutdown

Controller · Alarm

Alarm 2800 means the external shutdown circuit is open. The Evolution table does not add a part number beyond that external circuit.

Seen on: Air-cooled home standby generators with an Evolution 1.0 or 2.0 controller.

Likely causes

  • An emergency stop or other customer-connected shutdown switch is open.
  • A broken wire in that external shutdown loop, which the controller also sees as open.

Checks an owner can do

  1. If you know an emergency stop was installed, check whether it is pressed. Reset it only when it is safe to run.
  2. Do not jumper the shutdown circuit out.

When to call a pro

If there is no e-stop, or resetting it does not clear 2800, the wiring needs a technician.
