Message Description
TD S2 TO S1 Timer for the delay between transfer of transfer switch from S1 to S1
TD IN NEUTRAL When the automatic transfer switch is in the neutral position when both Source 1 and Source 2 are open, timer for delay
to transfer from neutral to Source 1 or Source 2 when they become available
TD ENGINE START Timer from delay in starting the engine when an engine start signal is received
TD S2 FAIL (TDS2F) Call to start the start of generator is received, timer starts for the controller to detect a healthy voltage on the source 2
TD ENGINE COOLDOWN A call to go back to normal source is received, timer starts for the delay to transfer back to normal to allow the engine cooldown
ENGINE TEST RUN Appears when a call for an engine test run is initiated, controller is operating from Source 2, and at least 20% of the
programmed motor full load amps is detected
ENGINE TEST FAIL Appears when the controller is operating from Source 2, a call to start the engine is initiated, the test run timer expires
and less than 20% of the programmed engine full load amps is detected
MOTOR TEST RUN Appears when a call for a motor test run is initiated, and at least 20% of the programmed motor full load amps is detected
MOTOR TEST ABORT Appears when the test run timer expires and less than 20% of the programmed motor full load amps is detected
ATS TRANSFER FAILURE When a signal is received of transfer and the transfer switch cannot initiate a transfer
SOURCE 2 DISCONNECTED Source two disconnect is switched off and there is not voltage present in source 2
S1 AVAILABLE Controller has detected voltage in source 1
S2 AVAILABLE Controller has detected voltage in source 2
S1 PHASE FAILURE A phase failure is detected in source 1
S2 PHASE FAILURE A phase failure is detected in source 2
S1 UNDER VOLTAGE The voltage measured by the controller is lower than the programmed under voltage alarm set point for the normal source
S2 UNDER VOLTAGE The voltage measured by the controller is lower than the programmed under voltage alarm set point for the emergency source
S1 OVER VOLTAGE The voltage measured by the controller has exceeded the programmed over voltage alarm set point for the normal source
S2 OVER VOLTAGE The voltage measured by the controller has exceeded the programmed over voltage alarm set point for the emergency source
S1 UNDER FREQUENCY The frequency measured by the controller is lower than the programmed under frequency alarm set point for the normal source
S2 UNDER FREQUENCY The frequency measured by the controller is lower than the programmed under frequency alarm set point for the
emergency source
S1 OVER FREQUENCY The frequency measured by the controller has exceeded the programmed over frequency alarm set point for the normal source
S2 OVER FREQUENCY The frequency measured by the controller has exceeded the programmed over frequency alarm set point for the
emergency source
S1 PHASE REVERSAL The controller has detected a phase reversal on the system voltage of the normal source
S2 PHASE REVERSAL The controller has detected a phase reversal on the system voltage of the emergency source
LOW SUCTION SHUTDOWN TIMER When a signal for low suction is initiated, the timer starts, the timer starts and if the input does not clean before the
timer is elapsed it shuts down the motor
LOW FOAM SHUTDOWN TIMER When a signal for low foam is initiated, the timer starts and if the input does not clear before the timer is elapsed it shuts
down the motor
LOW SUCTION SHUTDOWN The controller has shut down because of low suction
LOW FOAM SHUTDOWN The controller has shut down because of low levels of foam
REMOTE START/STOP A remote start/stop input signal is received
PROOF PRESSURE SWITCH A proof pressure switch input signal is received
ENABLE SEQUENTIAL START The sequential start is programmed to be enabled in the controller
GO TO SOURCE 1 A go to source 1 input signal has been received
GO TO SOURCE 2 A go to source 2 input signal has been received
MOTOR TEST ABORTED A call to abort the motor test is received by the controller and less than 20% of full load motor amps is detected by the controller
WAITING FOR S1 When the controller is in source 2, this indication shows as the controller is waiting for healthy voltage to appear in
source 1 to initiate a transfer from source 2 to source 1
WAITING FOR S2 When a to start the engine is initiated, the controller is waiting for source 2 to have healthy voltage to initiate a transfer
from source 1 to source 2
