IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS − This manual contains
important instructions that should be followed during
installation and maintenance of the generator set andbatteries.
Before operating the generator set (genset), read theOperator’s Manual and become familiar with it and theequipment. Safe and efficient operation can be
achieved only if the equipment is properly operatedand maintained. Many accidents are caused by failure
to follow fundamental rules and precautions.
The following symbols, found throughout this manual,alert you to potentially dangerous conditions to the oper-ator, service personnel, or the equipment.
This symbol warns of immediatehazards which will result in severe personal in-jury or death.
WARNING
This symbol refers to a hazard or un-safe practice which can result in severe person-al injury or death.
CAUTION
This symbol refers to a hazard or un-safe practice which can result in personal injuryor product or property damage.
FUEL AND FUMES ARE FLAMMABLE
Fire, explosion, and personal injury or death can resultfrom improper practices.
DO NOT fill fuel tanks while engine is running, un-
less tanks are outside the engine compartment.Fuel contact with hot engine or exhaust is a potentialfire hazard.
DO NOT permit any flame, cigarette, pilot light,
spark, arcing equipment, or other ignition sourcenear the generator set or fuel tank.
Fuel lines must be adequately secured and free of
leaks. Fuel connection at the engine should bemade with an approved flexible line. Donot use zinccoated or copper fuel lines with diesel fuel.
Be sure all fuel supplies have a positive shutoff
valve.
Be sure battery area has been well-ventilated prior
to servicing near it. Lead-acid batteries emit a highly
explosive hydrogen gas that can be ignited by arcing, sparking, smoking, etc.
EXHAUST GASES ARE DEADLY
Provide an adequate exhaust system to properlyexpel discharged gases away from enclosed orsheltered areas and areas where individuals arelikelyto congregate. Visually and audibly inspectthe exhaust daily for leaks per the maintenanceschedule.Make sure that exhaust manifolds are se-cured and not warped. Do not use exhaust gases toheat a compartment.
Be sure the unit is well ventilated.Engine exhaust and some of its constituents are
known to the state of California to cause cancer,birth defects, and other reproductive harm.
MOVING PARTS CAN CAUSE SEVEREPERSONAL INJURY OR DEATH
Keep your hands, clothing, and jewelry away from
moving parts.
Before starting work on the generator set, discon-
nect battery charger from its AC source, then dis-connect starting batteries, negative (−) cable first.This will prevent accidental starting.
Make sure that fasteners on the generator set are
secure. Tighten supports and clamps, keep guardsin position over fans, drive belts, etc.
Do not wear loose clothing or jewelry in the vicinity of
moving parts, or while working on electrical equip-ment. Loose clothing and jewelry can becomecaught in moving parts.
If adjustment must be made while the unit is run-
ning, use extreme caution around hot manifolds,moving parts, etc.
DO NOT OPERATE IN FLAMMABLE ANDEXPLOSIVE ENVIRONMENTS
Flammable vapor can cause an engine to overspeed andbecome difficult to stop, resulting in possible fire, explo-sion, severe personal injury and death. Do not operate agenset where a flammable vapor environment can becreated by fuel spill, leak, etc., unless the genset isequipped with an automatic safety device to block the airintake and stop the engine. The owners and operators of
the genset are solely responsible for operating the genset safely. Contact your authorized Cummins Power
Generation distributor for more information.
v
ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH
Remove electric power before removing protective
shields or touching electrical equipment. Use rubber insulative mats placed on dry wood platforms
over floors that are metal or concrete when around
electrical equipment. Do not wear damp clothing(particularly wet shoes) or allow skin surface to bedamp when handling electrical equipment. Do notwear jewelry. Jewelry can short out electrical con-tacts and cause shock or burning.
Use extreme caution when working on electrical
components. High voltages can cause injury ordeath. DO NOT tamper with interlocks.
Follow all applicable state and local electrical
codes. Have all electrical installations performed bya qualified licensed electrician. Tag and lock openswitches to avoid accidental closure.
DO NOT CONNECT GENERATOR SET DIRECT-
LYTO ANY BUILDING ELECTRICAL SYSTEM.Hazardousvoltages can flow from the generator setinto the utility line. This creates a potential for elec-trocution or property damage. Connect onlythrough an approved isolation switch or an ap-proved paralleling device.
GENERAL SAFETY PRECAUTIONS
Coolantsunder pressure have a higher boiling point
than water. DO NOT open a radiator or heat ex-changer pressure cap while the engine is running.To prevent severe scalding, let engine cool downbefore removing coolant pressure cap. Turn capslowly, and do not open it fully until the pressure hasbeen relieved.
Used engine oils have been identified by some state
or federal agencies as causing cancer or reproduc-tive toxicity.When checking or changing engine oil,take care not to ingest, breathe the fumes, or con-tact used oil.
Keep multi-class ABC fire extinguishers handy.
Class A fires involve ordinary combustible materials
such as wood and cloth; Class B fires, combustible
and flammable liquid fuels and gaseous fuels; Class
C fires, live electrical equipment. (ref. NFPA No. 10).
Make sure that rags or combustible material are not
left on or near the generator set.
Make sure generator set is mounted in a manner to
prevent combustible materials from accumulatingunder or near the unit.
Remove all unnecessary grease and oil from the
unit. Accumulated grease and oil can cause over-heating and engine damage which present a poten-tial fire hazard.
Keep the generator set and the surrounding area
clean and free from obstructions. Remove any de-bris from the set and keep the floor clean and dry.
Do not work on this equipment when mentally or
physically fatigued, or after consuming any alcoholor drug that makes the operation of equipment un-safe.
Substances in exhaust gases have been identified
by some state or federal agencies as causing can-cer or reproductive toxicity. Take care not to breathor ingest or come into contact with exhaust gases.
Do not store any flammable liquids, such as fuel,
cleaners, oil, etc., near the generator set. A fire orexplosion could result.
Wear hearing protection when near an operating
generator set.
To prevent serious burns, avoid contact with hot
metal parts such as radiator system, turbo chargersystem and exhaust system.

2. Control Operation
GENERAL
The following describes the function and operationof the PowerCommanddicators, control switches/buttons and graphicaldisplay are located on the face of the control panelas illustrated in Figure 2-1.
Normally, generator set configuration options areset at the factory. When a new control is installed ona generator set or when parts are replaced, the con-trol must be configured for that generator set. Setupand calibration procedures are described in Sec-tion 3.
Control 3200 (PCC). All in-
SEQUENCE OF OPERATION
When the PowerCommand control is in the AUTOmode, it will cause the generator set to start on re-ceiving a signal from a remote device. The controlwill initiate a starter cranking signal and verify thatthe engine is rotating. The control will provide suffi-cient fuel to the engine to accelerate to start discon-nect speed. On reaching that speed, the control willramp the generator set to idle (warm-up) or ratedspeed and voltage.
On reaching rated speed and voltage, the controlchecks the system bus voltage. If no bus voltage is
present, it will wait for a pulse from a remote Master
First Start Sensor. On receiving that pulse, the control will signal the paralleling breaker to close.
If bus voltage is present, the control will check forproper phase rotation, adjust the generator set tothe bus voltage and frequency level, and then syn-chronize the generator set to the system bus. Whena synchronous condition is achieved, the control willsend a signal to close the paralleling breaker.
Whenthe paralleling breaker is closed, the genera-tor set will assume it’s proportional share of the totalload on the system bus.
CONTROLPANEL POWER ON/OFF
MODES
The power on/off modes of the control panel and op-erating software are Power On, Screen Saver andSleep/Awake.
Power On Mode: In this mode, power is continu-ously supplied to the control panel. The control’soperating software and control panel LEDs/graphi-cal display will remain active until the Screen Savermode is activated.
2-1
Screen Saver Mode: Power to the graphical dis-
play will be removed after 10 minutes (generator set
not running or running). The 10 minute timer resets
and begins after each control panel action (any button or switch selection) or signal received by the operating software. The bottom LEDs of the Analog
AC Metering Panel (bar graphs) may remain on dur-ing Screen Saver mode, indicating that the operat-ing software is active (Awake mode).
If these conditions are not met, Sleep mode is disabled in Auto mode.
The graphical display can enter Screen Saver mode
even if Sleep mode is disabled.
If Sleep mode is enabled in Auto mode, Sleep modeis activated when there are no unacknowledgedfaults and Screen Saver mode is active.
When a “Warning” signal is sensed by the PCC (forexample,low coolant temp), the control will displaythe warning message. The control will remain activeuntil the Fault Acknowledge button is pressed toclear the warning message and start the 10 minutetimer.
Sleep/Awake Mode: In the Sleep mode, the con-trol’s operating software is inactive and the LEDsand the graphical display on the control panel are alloff. Sleep mode is a feature that is used to reducebattery power consumption when the control is notbeing used.
In Off mode, Sleep mode is activated when thereare no unacknowledged faults and Screen Savermode is active.
In Auto mode, Sleep mode can be enabled or dis-abled. When shipped from the factory, it is disabled.You can enable Sleep mode by making thesechanges:
Use InPower service tool toset Auto Sleep En-
able to Sleep in Auto.
Set switch S1 on the Genset/Paralleling Card
to Sleep/Off. This switch is located next to con-nector J8 and relay K9.
The operating software is initialized and the controlpanel LEDs and graphical display are turned on inresponse to one of the following:
Moving/pressing any control panel switch/but-
ton. (If Sleep mode is enabled in Auto mode,the control will remain asleep if Sleep modewas previously active in Off mode.)
Receiving a remote start input signal (genera-
tor set in Auto mode)
Receiving anactive DCD signal on the RS-232
port.
Modem RI latch becoming active.
Digital display waking up.
Lonworks (backplane) wakeup becoming ac-
tive.
Customer fault 2 or 3 only (shutdown or warn-
ing indicator is on).
Dial Out process becoming active.
To activate the control and view the menu displaywithoutstarting the generator set, press any buttonon the control panel.

CONTROL PANEL ASSEMBLY
The control panel assembly (Figure 2-1) consist of
two panels, the Operator Panel and the Switch Pan-el.
Dependent on site requirements, the Operator Pan-el is either mounted on the control panel assembly(full-featured) as shown in Figure 2-1 or containedin a separate enclosure and mounted remotely ofthe control panel assembly.
The function of several buttons on the control panelwill vary dependent on the location of the controlpanel (remote or local of the control panel assem-bly). If the function differs, it is noted as either “re-mote” or “local operator panel” in the button de-scription.
Operator Panel
The operator panel contains the following compo-nents:
Analog AC Metering Panel: This panel simulta-neously displays 3-phase line to line AC volts andcurrent, kW, power factor and frequency.
The meter panel is composed of a series of LEDs,that are configured in bar graphs for each function.The LEDs are color coded, with green indicatingnormalrange values, amber for warning levels andred for shutdown conditions.
Scales for each function are in % of nominal values.
Resolution is 1% for values close to nominal, and increases at values further from nominal.
Graphical Display: The graphical display is capable of displaying up to 9-lines of data with approximately 27characters per line. The display is used toview the menus of the menu-driven operating sys-tem.
The top three lines of the graphical display containthe following control information in the order de-scribed:
State Line−modes of operation, such as
Stopped, Time Delay To Start, Warm Up AtIdle, etc. (see Figure 2-2), and paralleling op-erations, such as Standby, Dead BUS Close,Synchronize, Load Share and Load Govern.
Action Line− system actions, such as Warning,
Derate, Shutdown Cool-down and Shutdown,and fault codes.
Description Line− Fault code messages.
DisplayMenu Selection Buttons: Six momentarybuttons—three on each side of the graphical dis-play window—are used to navigate through the sys-tem control menus and to adjust generator set pa-rameters. The button is active when the messageadjacent tothe button is highlighted (displayed in in-verse video).
2-4
Switch Panel
The switch panel contains the following components:
Emergency Stop Button: Push the button in for
emergency shutdown of the engine. If the engine is
not running, pushing the button in will prevent thestarting of the engine, regardless of the start signalsource (local or remote).
Fault Acknowledge: Press this button to acknowledge warning and shutdown messages after the
fault has been corrected.
To acknowledge a Warning message, the 0/Manual/Auto switch can be in any position. (It is not nec-
essary to stop the generator set to acknowledge an
inactive Warning condition.) To acknowledge ashutdown message with this button, the 0/Manual/Auto switch must be in the 0 (Off) position.
To reset:
1.Pull the button out.
2.Move the 0/Manual/Auto switch to 0.
3.Press the front panel Fault Acknowledgebutton.
4.Select Manual or Auto, as required.
Remote Start Indicator: This green lamp is litwhenever the control is receiving a remote run sig-nal. When flashing, it indicates a load demand stopmode.
Not in Auto Indicator: This red lamp flashes con-tinuously when the 0/Manual/Auto switch is not inthe Auto position. (If in Auto position and lamp isflashing, service is required.)
Shutdown Status Indicator: This red lamp is litwhenever the control detects a shutdown condition.The generator set can not be started when this lampis on. After the condition is corrected, shutdown in-dicators can be reset by turning the 0/Manual/Autoswitch to the 0 position, and pressing the Fault Ac-knowledge button.
Dependent upon the specific fault that occurs, theengine may or may not shut down immediately. Afault that could cause engine damage, causes animmediate engine shutdown (bypasses enginecool-down sequence). All other faults would allowthe engine to run during the cool-down sequencebefore engine shutdown. In this case, the ShutdownStatus Indicator blinks during the cooldown period.
This button is also used to blink a fault code if theShutdown or Warning Status Indicator is lit. (Thisfunction isused when the control does not contain agraphicaldisplay.)Refer to Reading Fault Codes inthis section, which describes how to use this buttonfor interpreting fault codes.
PanelLamp/Lamp Test Button: Press this buttonto turn on or off the panel lamp. Press and holddown this button for three seconds or more to turnall control panel LEDs on to make sure all lamps illu-minate. The illumination will shut off after releasingthe button.
Exercise Button: Press this button to initiate a pre-programmedexercise sequence. To start the exer-cise sequence, press and hold down the Exercisebutton and move the O/Manual/Auto switch fromAuto toManual and back to Auto or from Manual toAuto.
Manual Run/Stop Button: This button starts andstops the set locally and will bypass Time Delay toStart and Stop sequences. The 0/Manual/Autoswitch must be in the Manual position to enable thisbutton.
0/Manual/Auto Switch: Manual position enablesthe use of the switch panel Manual Run/Stop but-ton.
Auto position enables start/stop control of the en-gine from a remote location. (Disables the use of theswitch panel Manual Run/Stop button.)
Warning Status Indicator: This yellow lamp is litwhenever the control detects a warning condition.After the condition is corrected, warning indicatorscan be reset by pressing the Fault Acknowledgebutton. (It is not necessary to stop the generator setif the fault becomes inactive during genset opera-
tion.)
0(Off) position prevents the starting of the set (localor remote). If moved to 0 during set operation, willcause an immediate engine shutdown (bypassescool-down timers). This hot shutdown should beavoided, if possible, to help prolong the life of theengine. Hot shutdowns are logged by the system
software.
2-5
READING FAULT CODES
If the genset contains the optional graphical display
and a fault occurs, the fault code/message will be
displayed in the display Description Line (Figure
2-2). If the control does not contain the graphical
display, the fault code is read from the Warning and
Shutdown status indicators.
A three digit fault code is indicated by three sets of
blinks separated by a two second pause. The first
set corresponds to the hundreds position, the second to the tens position and the third to the ones digit. Example for Code No. 213:
Shutdown LED:
blink-blink-pause-blink-pause-blink-blink-blink
Reading Fault codes Using Warning/ShutdownIndicators:If the Warning or Shutdown status indi-
cator is lit, press and hold the Fault Acknowledgebutton and release after one second or more. Afterone second, the Shutdown lamp will begin to blinkthe active fault code(s) as follows.
The Warning lamp is used to indicate the start of anew code. The Warning lamp will remain on for 2seconds, followed by the Shutdown lamp blinkingthe fault code. This sequence occurs three times foreach code. The fourth flash of the Warning lamp in-dicates the beginning of the second fault code.
Thereare distinct pauses between repetitions of thecode blink transmissions of the Shutdown lamp.
Warning LED:
blink (2 seconds)
The light will display the fault codes (active or inac-tive) insuccession, starting with the most recent. Upto 32 (unacknowledged) fault codes can be storedin control panel memory.
To return the control to the most recent fault code,press and release the Fault Acknowledge button(less than one second) and repeat procedure.
When the fault code is acknowledged and cor-rected, the recorded fault will be deleted from theLED fault log, but will remain in a data log that main-tains afault code history. (The InPower service toolis required to view this data log.)
