Stopping Generator Set
Local Stopping
1. Run the generator set with no load for at least
2 minutes to ensure adequate engine cooldown.
2. Move the generator set master switch to the OFF/
RESET position. The engine stops.
Automatic Stopping
With the generator set master switch in the AUTO
position, open the contact across engine start leads 3
and 4 to signal the generator set to stop.
An automatic transfer switch (ATS) connected to
controller leads 3 and 4 operates as follows:
1. The ATS disconnects the load from the generator
set.
2. If the ATS is equipped with an engine cooldown
time delay, the generator set continues to run for a
preset engine cooldown time.
Note: There is no engine cooldown time delay on
the DC-RET controller.
3. The ATS opens the connection between controller
leads 3 and 4. The generator set shuts down. The
controller enters standby mode and displays
engine runtime hours.
2.5 Exercising Generator Set
Operate the generator set without load once each week
for 20 minutes. If the generator set is not connected to
an automatic transfer switch (ATS) with an exercise
option, exercise the unit in the presence of an operator.
The operator should perform all of the prestart checks
before starting the exercise procedure.
generator set according to the starting procedure in the
controller section of this manual. While the generator
set is operating, listen for a smooth-running engine and
visually inspect the generator set for fluid or exhaust
leaks. Check the air inlets and outlets and remove any
items restricting the air flow.

2.6 Faults
2.6.1
Under the fault shutdown conditions listed in Figure 2-3,
the generator set shuts down automatically and the
controller displays a fault code. The generator set
cannot be restarted until the fault condition is corrected
and the controller is reset. See Section 2.6.3 to reset the
controller after a fault shutdown.
The switches on the generator set will automatically
reset when the problem is corrected. For example, the
high engine temperature switch resets automatically
when the generator set cools. However, the controller
fault does not clear until the controller is reset.
2.6.2
The controller displays a fault code but the generator set
does not shut down on a low battery voltage warning.
The controller resets automatically after a battery
voltage fault condition is corrected.
2.6.3
Always identify and correct the cause of a fault
shutdown before resetting the controller. Check the
fault code displayed on the DC-RET and refer to
Figure 2-3 to identify and correct the fault condition
before proceeding.
Use the following procedure to reset the generator set
controller after a fault shutdown.
1. Move the generator set master switch to OFF/
RESET.
2. Disconnect the generator set from the load using
the line circuit breaker or ATS. See the safety

3. Identify and correct the cause of the fault
shutdown.
beginning of this manual before proceeding. Refer
to Section 5, Troubleshooting.
4. Start the generator set by moving the generator set
master switch to RUN. Test operate the generator
set to verify that the cause of the shutdown has
been corrected.
