Appendix A: Status Display Messages
All possible Status Display Messages are shown below. For additional information, refer to paragraph 3.4.1.
Status Display Message Display Message Meaning
TDEC Countdown cool off timing before generator contacts are opened.
TDES Countdown timing before generator contacts are closed.
TDNE Countdown timing before normal breaker is opened for transfer to the emergency source.
TDN Countdown timing with both sources disconnected from the load.
TXFR Waiting for the switch to make the transfer from neutral position to the intended source.
TDEN Countdown timing before the emergency breaker is opened for transfer to the
normal source.
NEUTRAL Both breakers (or contactors in the case of a contactor type ATS) are opened and the load is dis-
connected.
MANUAL Waiting for an input signal to complete the manual re-transfer.
LOCK-OUT A trip condition has been detected by either breaker (or contactor in the case of a contactor type
ATS) and the system is locked-out from further transfers, or Option 9B, Maintenance Selector
Switch, is in the “OFF” position.
TER 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.
START To initiate an engine test sequence press Engine Test pushbutton again or press Increase and
Decrease simultaneously to clear.
WAIT Waiting for the generator source voltage and frequency to become available.
TDNV Waiting for load voltage to decay before completing the transfer.
TDP Countdown timing while waiting for a pre-transfer acknowledge input.
TSEQ Countdown timing between sequenced loads.
NO R xx No communications response on the sub-network was received from Addressable Relay II, set for
address xx.
WAIT NEU Waiting for the neutral position to be reached by the switch.
WAIT S1 Waiting for Source 1 breaker (or contactor in the case of a contactor type ATS) to open/close dur-
ing a closed transition.
WAIT S2 Waiting for Source 2 breaker (or contactor in the case of a contactor type ATS) to open/close dur-
ing a closed transition.
TSIP Countdown timing while waiting for sources to synchronize for an in-phase transition.
TSCT Countdown timing while waiting for source to synchronize for a closed transition.
ABORT Indicates that an engine test or plant exercise was aborted after three unsuccessful attempts. The
Emergency Source did not remain available while TDNE was timing.
INHIBIT Indicates that a transfer to the Emergency Source is inhibited because the Emergency Inhibit input
is activated.
S1 BRKR Indicates that the Source 1 circuit breaker failed to open or close. (only for CAT#8160A00G42)
S2 BRKR Indicates that the Source 2 circuit breaker failed to open or close. (only for CAT#8160A00G42)
S1 CONT Indicates that the Source 1 contactor failed to open or close (only for CAT#8160A00G43)
S2 CONT Indicates that the Source 2 contactor failed to open or close.(only for CAT#8160A00G43)
1-2 FAIL Source 1 Breaker or Contactor did not open during a close transition within 100 milliseconds
Source 2 Breaker or Contactor did not close during a close transition within 100 milliseconds
2-1 FAIL Source 2 Breaker or Contactor did not open during a close transition within 100 milliseconds
Source 1 Breaker or Contactor did not close during a close transition within 100 milliseconds
