TP-6905 9/21 20 Section 2 Generator Set Operation
Pressure is monitored at both low and full speeds. If
the oil pressure is low, low oil pressure is displayed
and the generator set shuts down.
2.5.2 Unloaded Full-Speed Exercise
The unloaded full speed exercise runs the generator set
at full speed for 20 minutes without transferring the load.
To set an unloaded full speed exercise, follow the
procedure in Figure 2-3 and select Exercise Mode:
Unloaded Full.
2.5.3 Loaded Full-Speed Exercise (with
RXT only)
A loaded exercise starts the generator set, ramps up to
full speed, and then transfers the electrical load from the
utility source to the generator set. The load is transferred
back to the utility source before the generator set shuts
down.
Note: With a loaded exercise, power to the building is
lost for up to 10 seconds during load transfer.
For a loaded exercise controlled by the RDC2 controller,
a Model RXT transfer switch must be connected to the
generator set. To set a loaded exercise, follow the
procedure in Section 2.5.8 and select Exercise Type:
Loaded.
For a loaded exercise with a transfer switch other than a
Kohler
r
Model RXT, program the exercise at the
transfer switch controller. Refer to the transfer switch
operation manual for instructions.
2.5.4 Shutdown During Exercise
The following advanced diagnostic operation applies to
RDC2 controllers with firmware versions 5.04 and
higher.
If the generator set shuts down on a fault during an
exercise, the controller will try to restart the engine. If the
engine starts, the generator set will run at full speed for
two minutes and then stop. The event history will show
Advanced Diagnostic Active. The exercise schedule is
maintained.
If the engine does not start, the shutdown message will
be displayed. Correct the fault condition and reset the
fault as described in Section 2.6.
2.5.5 Power Failure During Exercise
If the utility power is lost during an unloaded exercise,
the ATS transfers to the emergency source, the exercise
is ended and the control remains in the AUTO mode.
If the utility power is lost during a loaded exercise, the
exercise is ended. The ATS remains in the emergency
position and the control goes into the AUTO mode.
The generator set continues to run and supply power to
the load for the duration of the utility power outage.
When Utility power is restored, the ATS will re-transfer to
the utility source through normal timing sequences.
2.5.6 Exerciser Reset
To reset the exerciser to run at a different day and/or
time or to change the exercise mode, follow the
procedure in Section 2.5.7 to change the exerciser
settings.
