Countdown cool-off timing before the generator contacts are opened.
Countdown timing before the generator contacts are closed.
Countdown timing before Source 1 is disconnected before transferring to Source 2. Timing begins when Source
2 is available.
Countdown timing with both sources disconnected from the load.
Countdown timing before Source 2 is disconnected before transferring to Source 1. Timing begins when Source
1 becomes available.
Waiting for the switch to make the transfer from the neutral position to the intended source.
Control input for monitor mode is closed.
A trip condition has been detected by either breaker, and the system is locked-out from further transfers.
The engine run test timer is counting down before the test is completed. Pressing the Engine Test pushbutton
will abort this timer and the test.

Indicates that the Source 2 device (i.e. circuit breaker, contactor) failed to open or close.
Countdown timing before declaring Source 2 unavailable (accounts for momentary generator fluctuations).
Countdown timer before declaring a source unavailable due to a voltage unbalance condition.
Indicates that an engine test or plant exercise was aborted after three unsuccessful attempts. Source 2 did not
remain available while TDNE was timing.
Indicates that the load is connected to Source 2 because the Go To Source 2 control input is in the "uncon-
nected" state.
Indicates that the load was connected to Source 2 but Source 2 became unavailable so the load transferred back
to Source 1.
