Not in Auto

Controller · Warning

Warning, not a fault in the hardware sense. TP-7092: the generator is not in Automatic, so remote start and stop from a transfer switch or remote switch are ignored. The check is to press AUTO when it is appropriate for the set to be in standby.

Seen on: 14RCA, 14RCAL, 20RCA, 20RCAL, 26RCA, and 26RCAL sets with the RDC2 controller (TP-7092).

Likely causes

  • The controller was left in OFF or RUN after maintenance or a fault reset.
  • Someone stopped it locally and did not return it to Auto.

Checks an owner can do

  1. If you intend the set to cover the next outage, press AUTO.
  2. Leave it in OFF if you are still working on a shutdown fault.

When to call a pro

No dealer visit is required for the warning itself. If it will not stay in Auto, then call.
