TP-6734 5/10 24 Section 2 Operation
before the generator set engine stops. The
generator set goes into Auto mode.
Immediate Shutdown During a Loaded Test
Press the OFF button to shut the generator set down
immediately, if necessary. The cooldown time delay is
ignored, and the controller goes to OFF mode. The
controller signals the RRT transfer switch to transfer the
load back to utility power.
Note: Running the generator set with no load for at least
2 minutes is recommended to ensure adequate
engine cooldown. Use the OFF button to stop a
loaded test only if necessary.
2.8.3 Power Failure During Test Cycle
If the utility power is lost during an unloaded test, the
ATS transfers to the emergency source and the test is
ended. The control goes into the AUTO mode.
If the utility power is lost during a loaded test, the test is
ended and the ATS remains in the emergency position.
The control goes into the AUTO mode.
When Utility power is restored, the ATS re-transfers to
the utility source through normal timing sequences.
2.9 Faults
Fault conditions are shown in Figure 2-7. Fault
conditions are classified as warnings or shutdowns.
2.9.1 Warnings
The controller displays a fault code but the generator set
does not shut down on a warning. The controller resets
automatically after a warning condition is corrected.
2.9.2 Shutdowns
Under a fault shutdown condition, the generator set
shuts down automatically and the controller displays a
fault code. In some cases, the engine cooldown cycle
runs before the engine shuts down. See Figure 2-7.
Shutdown switches (such as the low oil pressure switch
or high engine temperature switch) on the generator set
will automatically reset when the problem is corrected.
However, the fault condition at the controller does not
clear until the controller is reset.
The generator set cannot be restarted until the fault
condition is corrected and the controller is reset. See
Section 2.9.4 to reset the controller after a fault
shutdown.
2.9.3 ATS Communication Errors
An ATS fault can be caused by two conditions.
D
When a model RRT transfer switch is used, an ATS
fault indicates that communication with the interface
board on the transfer switch has been lost.
The
generator set shuts down. Check the connection to
the ATS interface board.
D
When a model RDT or RSB transfer switch is used,
an ATS fault indicates that connection to the ATS
interface board is detected when it is not expected. A
warning is displayed but the generator set does not
shut down.
2.9.4 Resetting the Controller after a
Fault Shutdown
Always identify and correct the cause of a fault
shutdown before resetting the controller. Check the
fault code displayed on the controller and refer to
Figure 2-7 to identify and correct the fault condition
before
proceeding. Contact an authorized
distributor/dealer for service, if necessary.
Procedure to Reset the Controller after a Fault
Shutdown
1. Press OFF to turn off the generator set.
2. Disconnect the generator set from the load using
the line circuit breaker or ATS. See the safety
precautions at the beginning of this manual before
proceeding.
3. Identify and correct the cause of the fault
shutdown. See the safety precautions at the
beginning of this manual before proceeding. Refer
to Section 4, Troubleshooting.
4. Start the generator set by pressing RUN. Check
the generator set operation to verify that the cause
of the shutdown has been corrected.
5. Press the OFF button to stop the generator set.
6. Reconnect the generator set to the load using the
line circuit breaker or ATS.
7. Press AUTO to put the generator set into automatic
mode.
