TP-6200 10/1234 Section 2 Operation
Auto Starting
Move the generator set master switch to the AUTO
position to allow startup by the automatic transfer switch
or remote start/stop switch (connected to controller
terminals 3 and 4).
Terminals 3 and 4 connect to a circuit that automatically
starts the generator set crank cycle when an external
source closes the circuit.
Note: The controller provides up to 30 seconds of
programmable cyclic cranking and up to
60 seconds rest with up to 6 cycles. The default
setting is 15 seconds cranking and 15 seconds
rest for 3 cycles. Make cyclic cranking
adjustments using the keypad. See Section 2.8.14,
Menu 14—Programming Mode, and Section 2.8.8,
Menu 8—Time Delays.
Idle (Speed) Mode Warmup and Cooldown
Function
The idle (speed) mode function provides the ability to
start and run the engine at reduced speed for a
selectable time period (0--10 minutes) during warmup.
See Section 6.1.5, Idle (Speed) Mode Feature, for
installation information.
The controller will override the idle speed mode when
the engine reaches the preprogrammed engine
warm-up temperature before the idle mode times out.
The idle function also provides engine cooldown at idle
speed. The controller overrides the idle speed mode
when the engine reaches the preprogrammed engine
cooldown temperature before the idle mode times out.
During the idle (speed) mode the controller continues to
monitor critical engine parameters such as oil pressure,
coolant temperature, and engine speed. The voltage
regulator, thermal protection feature, and AC metering
are disabled in the idle speed mode.
The controller overrides the idle speed function when
the generator set is signaled to start while in the AUTO
position. This override provides emergency generator
set power in the event of a utility power failure. When the
utility power returns and the generator set is signalled to
stop, the generator set continues to run for the duration
of the idle mode period when the idle mode is active.
When the idle mode is not active, the generator set will
shut down in the normal stopping mode including time
delays.
See Menu 9—Input Setup to activate the idle speed
function as a user-defined digital input. The idle speed
feature requires an ECM-equipped engine with the idle
speed function.
Run Time Feature
The run time feature allows the user to set up the
generator set to run unassisted and automatically return
to the standby mode. The user does not need to wait for
the exercise period (run time) to conclude in order to
place the unit back in the standby mode. See
Menu 4—Operational Records for setup of this feature.
With the run time enabled, the generator set will begin to
crank and run based on the run time period and all
previously established time delays from Menu 8—Time
Delays.
Generator Set Connected to an Automatic Transfer
Switch. Should a utility power failure occur while the
unit is in the run time mode, the controller will bypass the
run time mode and function in the standby (backup)
mode. When the utility power returns, the generator set
continues to run for the duration of the run time period
when not timed out.
Note: Press the STOP PROG RUN key, when
necessary, to stop the generator set when it is in
the run time mode.
Prime Power Switch
The digital controller has an optional prime power mode
of operation. The prime power mode requires
installation of an optional prime power switch kit. See
Section 6, Accessories, for instructions on how to install
the optional prime power switch kit. The prime power
switch kit prevents engine starting battery drain when
the generator set is shut down and no external battery
charging is available.
Move the prime power switch located on the back of the
controller to the CONTROLLER ON position and set the
controller time and date before attempting to start the
generator set. When the prime power mode is off, all
controller functions including the digital display, LEDs,
and alarm horn are operative.
Note: After energizing the controller using the prime
power switch, set the controller time and date.
See Section 2.8.6, Menu 6—TIme and Date.
Stop the generator set using the stopping procedures in
Section 2.3.2 before placing the generator set in the
prime power mode. Move the prime power switch
located on the back of the controller to the
CONTROLLER OFF position. When the generator set
is is the prime power mode, all controller functions
including the digital display, LEDs, alarm horn, and
communications are inoperative.
