TP-6109 6/03 13Section 2 Operation
2.6.6 Prime Power Mode Operation
The Decision-Makert 3+ controller operates in either
the normal mode or the prime power mode. In prime
power mode, the controller draws less current,
minimizing the battery drain. Consider using the prime
power mode for installations that do not have a battery
charger.
Moving the generator set master switch to the
OFF/RESET position disables all controller functions.
Moving the generator set master switch to the AUTO
position restores controller functions.
Enabling and Disabling the Prime Power Mode.
Enable the prime power mode by connecting jumpers
across the following terminals on terminal strip TB2 on
the controller circuit board:
D TB2-1P and TB2-2P
D TB2-3P and TB2-4P
D TB2-3 and TB2-4
See Figure 2-3. Remove the jumpers listed above to
disable the prime power mode.
Prime Power Starting. The prime power mode
provides local starting only at the controller. When the
generator set master switch is in the OFF/RESET
position, the controller functions are inoperative. Move
the generator set master switch to the AUTO position to
start the generator set. Do not start the generator set
with the master switch in the RUN position because the
alarm horn will sound.
Note: Move the generator set master switch to the
AUTO position to return controller functions to
normal.
Prime Power Stopping. Move the generator set
master switch to the OFF/RESET position to stop the
generator set and power down the controller.
Note: The controller functions are inoperative when the
generator set master switch is in the OFF/RESET
position.
2.6.7 Fault Shutdowns
The generator set shuts down automatically under the
following fault conditions and cannot be restarted until
the fault condition is corrected. The system
automatically resets when the problem is corrected or
the generator set cools (if high engine temperature was
the fault).
Name Description
High engine
temperature
Shutdown occurs 5 seconds after
the fault. The high engine
temperature shutdown does not
function during the first 5 seconds
after startup.
NOTE: The high temperature
shutdown functions only when the
coolant level is in the operating
range.
High exhaust
temperature
Shutdown occurs 5 seconds after
the fault. The high exhaust
temperature shutdown does not
function during the first 5 seconds
after startup.
Low coolant level
(water-cooled
engines only)
Shutdown occurs 5 seconds after
fault. The low coolant level
shutdown does not function during
the first 5 seconds after startup.
Low oil pressure Shutdown occurs 5 seconds after
the fault. The low oil pressure
shutdown does not function during
the first 5 seconds after startup.
NOTE: The low oil pressure
shutdown does not protect against
low oil level. Check the engine oil
level.
Overcrank Shutdown occurs after 45 seconds
of continuous cranking or
75 seconds of cyclic cranking
(crank 15 seconds, rest
15 seconds, crank 15 seconds,
etc.).
Overspeed Shutdown occurs immediately
when the governed frequency on
50 and 60 Hz models exceeds
70 Hz.
Overvoltage
(optional)
The generator set shuts down and
the auxiliary lamp lights when
voltage is 15% or more over the
nominal voltage for 2 seconds or
longer.
NOTE: Overvoltage can damage
sensitive equipment in less than
one second. Install separate
overvoltage protection on on-line
equipment requiring faster
shutdown.
