Controller Power; Standby Mode; Sleep Mode; Generator Set Operation - Kohler 17RES Operation Manual

2.4 Controller Power

The ADC-RES is powered by the generator set engine
starting battery.
Note: The generator sets are equipped with factory-
installed battery chargers to prevent battery
discharge. The battery charger must be
connected to 120 VAC.
2.4.1

Standby Mode

When the generator set master switch is in the AUTO
position, the controller is in standby mode. Engine
runtime hours are shown on the display. A remote start
signal (contact closure) will start and run the generator
set.
If there is no start signal for 48 hours, the controller goes
into sleep mode.
2.4.2

Sleep Mode

When the generator set master switch is in the AUTO
position, the controller powers down automatically if
there is no start signal for 48 hours after shutdown. The
controller display is dark and battery draw is minimized.
A remote start signal (from a transfer switch or a remote
start/stop switch connected to controller leads 3 and 4)
reactivates the controller. Moving the generator set
master switch to the RUN position also activates the
controller.

2.5 Generator Set Operation

2.5.1

Starting Generator Set

Local Starting
Move the generator set master switch to the RUN
position to immediately start the generator set.
Auto (Automatic) Starting
Move the generator set master switch to the AUTO
position to allow startup by an automatic transfer switch
(ATS) or remote start/stop switch, if equipped. Close a
contact across engine start leads 3 and 4 to signal the
controller to start the generator set.
TP-6515 10/07
Crank Cycle
The controller attempts to start the generator set three
times (three crank cycles, 15 seconds crank and
15 seconds off). See Figure 2-3 for display information
during the crank cycle. If the generator set does not start
in three attempts, the system shuts down on an
overcrank fault. See Section 2.6.
2.5.2

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 ADC-RES 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.
