The new generation of PowerCommand Controls will use a new easier to understand naming system. The new controls are modular and therefore it can be confusing to know what feature are being used it the genset control system is only referred to by the control board model. There are several combinations of control boards and HMIs

PCC 1302 PCC 1.1 (HMI 211) PCC 1.2 (HMI 220) PCC 2300 Phase 1 (2.2) (FAE) - HMI 220, HMI 112 or 114, HMI 113 Phase 2 (2.3) (HM) - HMI 220 or 320, HMI 112 or 114, HMI 113, AUX 101/102, AUX 104 PCC 3300 Phase 1 (3.X) - HMI 220 or 320, ?????????????? Phase 2 (3.X) - HMI 220 or 320, ??????????????Naming Chart - PCC 1.X, 2.X, 3.X Naming System
The above naming chart shows the naming system for the new series of controls, PowerCommand Control 1.X, 2.X, and 3.X. The X represents the HMI Operator Panel you have with the series of control board.
Here is a list showing how they are structured:
1.X
= PCC 1302 control board2.X
= PCC 2300 control board3.X
= PCC 3300 control boardX.3
= HMI 320The PCC 2.X and 3.X will be released in a couple of different phases. These phases will support certain devices as depicted in the visual above and in more detail throughout this training course. The 2.X, & 3.X series designation will identify the high level of control ability however, there will be several subcategories of different control board features. The first category of 2.X, & 3.X controls will only work on FAE controlled engines. The next category will be used with hydra mechanical engine applications. As new features and categories develop, additional training courses will also develop.
Series 2.X with FAE control training and 3.X with FAE control training will be the most comprehensive training programs about the PCC 2300 and PCC 3300 controls. The training programs that follow will concentrate on the specific feature enhancements, HMI, or accessory developments relative to the specific Series. The Series 2.X & 3.X FAE training will be a prerequisite to any future training program
Welcome!
Welcome to the Instructor’s Guide for the PowerCommand Control 1302 module! This guide was written by the Cummins Power Generation Sales and Technical Training department for your use and reference.
We suggest you read through the entire Introduction to become familiar with the guide’s structure. Then, just follow the step-by-step instructions for each lesson.
Module Purpose
The purpose of the PowerCommand Control 1302 module is to help you, the Cummins Power Generation distributor service technician, understand the PowerCommand Control 1302 which is going to replace the specialized Onan gen set control modules (e.g., DN, GN). It is also expected that the PowerCommand Control 1302 will be used on many of the Cummins−powered gensets with Full Authority Engines (FAE) and the hydro−mechanical fuel systems up to 1500 kW. With this information, our technical force will be better prepared to meet our customers’ varying needs.
Module Audience
The primary audience for this module is Cummins Power Generation distributor power
generation technicians. We assume participants have previous experience with or knowledge of Integrated generator set AC and DC control operation, troubleshooting, and repair procedures.
Module Structure
This module contains lessons on related topics. Each lesson follows a carefully designed training format, including a warm up, presentation, and activity (or exercise).
Lesson Format
Warm ups help participants focus and begin thinking about the lesson topic. The presentation
portion of the lesson is where participants receive new information. The activity follows the presentation; it gives participants the chance to practice new skills or work with new ideas.
Module Assessment
After completing all the lessons in the module, participants will complete a module assessment. The module assessment lets us evaluate the level of knowledge participants have on the topic after completing the module.
Module Comment Form
Participants will also complete a module comment form. This form gives participants the chance to comment on the usefulness and effectiveness of the training module and make suggestions for improvements.
We will use the results from the module assessments and module comment forms to help us determine if there is a need to modify the module.
Please mail the module assessments and comment forms to Cummins Power Generation’s Sales and Technical Training department as soon as possible after the training session. The address is: Cummins Power Generation
Sales and Technical Training OUJ3 1400 73rd Avenue NE
Minneapolis, MN 55432
Preparing for the Training Session
To simplify your preparations for the training session, we’ve broken out your major tasks. Coordinate the session
• Arrange for a location, date, and time convenient for the session participants. Plan the session as far in advance as possible.
• Try to arrange for a quiet, seminar-type meeting place, away from the participants’ regular work area.
• Do as much as possible to help make participants comfortable. • Arrange for refreshments and meals, if appropriate.
Preview the lessons−−Review the lesson objectives and read through the trainer’s instructions. Use the Notes column to write any comments or additional information you want to include.
Organize and prepare the module training materials−−Make copies of the module assessment and the module comment forms (found at the back of this trainer’s guide) for each participant to complete at the end of the module.
• Review the Materials Needed section at the beginning of each lesson and order the
appropriate number of participant’s guides, sales literature, and materials in advance from Onan’s Literature department using a copy of the form found at the end of this section. • Note: We recommend you order materials two to three weeks in advance of your session. • Note: You will also have to order kits of InPower service software, a manual, and a hardware
or software lock for the training participants.
Arrange for training equipment−−For most Service Training lessons, you will need an overhead or slide projector and screen (with remote control, if available), a flipchart stand with paper and markers (or a whiteboard or blackboard and chalk), and specific hardware to use as a demonstrator unit for the lesson.
Since each technician attending the course will be bringing a laptop PC and using the PC during the course of instruction, you may want to alert your IS department in case the technicians’ PCs need tweaking to operate properly.
Confirm attendance−−A few days before the session, verify who will be attending. We recommend conducting the session with three to ten participants.
Set up the room−−Plan to arrive at least 30 minutes before the session begins. Check the lighting, acoustics, and temperature of the room. Find out how to adjust the lighting and temperature.
• Make sure all equipment (such as slide and overhead projectors, extra bulbs, flipchart stands) is in place and in working order before the session begins.
• If possible, have tables large enough for three participants to have their guides and a demonstrator on the table at the same time.
Introductions
At the beginning of the session, have each person introduce himself or herself and say a few words about his or her experience with the subject to be covered.
As an alternative, you might want to let participants interview each other and introduce the person they interviewed to the group. If participants do not know each other, make name tags and table top name tents and ask participants to use them throughout the session. Expectations
After introductions, label a flipchart page with the word Expectations. Ask the participants what expectations they have for the session, then explain which of their expectations you will be able to address. If you will not be able to address all of the participants’ expectations, arrange to follow up on their concerns at a later date.
Lessons
The first time you conduct the training for this module, follow the step-by-step lesson instructions. Feel free to add comments from your own experience, but follow the structure of the module. Once you are familiar with the module you can modify the session for the specific needs of the group.
Use this check list to help you prepare for the training session.

Operation Sequence
Visual 3-4 PCC 1.X Sequence of Operation Participant’s Text
Manual Operation
1. Operator presses switch to START / PREHEAT side to preheat engine. If engine temperature is low enough, the control heats the glow plugs if so equipped. After the preheat TD completes, the control cranks the engine.
2. If the engine rotates, the control keeps cranking. If the engine does not rotate, the control stops cranking for 2
second, then cranks again. If the engine still does not rotate, the control faults out on Fail to Crank.
will deliver fuel to the cylinders and the engine will start running. 4. Once the engine reaches a high
enough speed, the Battery Charge Alternator will deliver a 7 Volt DC voltage to the board and will disconnect the starter.
5. The engine will accelerate to rated speed, and regulate there.
6. As the engine approaches rated speed the Voltage Regulator will start exciting the exciter stator and the output voltage will start to build up to rated value.
7. When the main Alternator output nears the rated value, the regulator will start to reduce the excitation to the exciter stator and the output voltage will even out at rated value. 8. The operator will apply a load to the generator set that does not exceed the ratings of the engine and alternator. 9. When the generator is no longer
needed, the operator will remove the load and allow the engine/generator to cool down at rated speed with no load for approximately five minutes. 10. At the end of the cooldown period the
operator will move the switch to the STOP position and the genset will stop.

There are two ways to reset faults on the PCC1302.
Fault Handling & Acknowledgement
Local Fault Reset:
Faults are reset at the HMI by pressing the button
Or by placing the Auto/Manual/Off switch into the off position.
Remote Fault Reset:
Must be enabled by a software trim.
Uses one of the configurable inputs.
In auto mode:
-The remote start signal must be removed.
-And the remote fault reset input must be activated.
The remote fault reset input has no effect if the Auto/Manual/Off switch is not in the Auto Position.
Visual 3-5 PCC 1302 Sequence of Operation Participant’s Text
Fault Acknowledgement
IF the control is equipped with an operator panel, press the button.
If the control is not equipped with an operator panel, place the Auto/Off/Manual Run switch in the Off position
Refer to page 4-6 of 900-0661
Operator/Installation Manual for more information about Reset and
Acknowledgement.
Fault Acknowledgement can be activated remotely and can also be activated via a ModBus command.

Bi-directional System Wakeup.
The PCC1302 has implemented a wakeup scheme using the Bi-directional wakeup pin (J25-5 and TB15-5).
If one PCCNet device awakens, it will wake up the other PCCNet devices by driving the Bi-directional system wakeup pin.
When all devices are satisfied, the PCCNet will go to sleep as one system.Visual 3-6 PCC 1302 Wakeup Sequence
Participant’s Text
The PCC1302 will wake up with a command from other PCCNET devices on the network. Depending on the type of PCCNET device, it will have the ability to go to sleep if it is inactive for a prescribed period. Once awaked, it will send out a wakeup command to the rest of the PCCNET devices on the network.
The PCCNET devices will also go to sleep if there are no other devices sending a wakeup signal. At this time, only the HMI and the PCC 1302 control board are the only 2 devices employing the bi-directional wake up.
The PCC 1302 power consumption changes depending which of mode of sleep or wake it is in.
Running - .750 amp ( 750 mAmp) Parade Rest Mode (awake but not
running) .15 amp ( 150 mAmp) Sleep Mode- .06 amp ( 60 mAmp) Parade Rest Mode (previously called Idle
Mode) describes a state of operation when the
control is awake but the genset is not running. The control can be in this power consumption mode if it is in manual or Awake in Auto. Awake in Auto will be discussed a few pages ahead.

PGI CAN is a form of SAE J1939 CAN communications between the Cummins ECM and the PowerCommand Control. SAE J1939 CAN communications list
thousands of fault code for many engine functions and faults. Most of the fault codes are not important to the average generator operator or
technician and most would confuse operators. PGI CAN is only concern about certain faults so any serious faults or warnings not listed above are communicated as Fault Code #1246, which is referred to as a General Engine Fault.

Data Messages the PCC1302 Supports:
Intake Manifold Temperature
Engine Oil Temperature
Engine Oil Pressure
Fuel Rate.
Engine Coolant Temp
Engine Speed.
Engine Running Time.
Water In Fuel Indicator
*** IMT, Engine Oil Temperature, and Fuel Rate are not viewable from the HMI211.
Visual 3-11 PCC 1302 PGICAN Participant’s Text
In addition to the ability of the ECM to communicate engine faults to the PCC 1302, the PCC 1302 also recognizes the engine operating information list above.
The ECM processes information from the various engine sensors and then sends digital messages to the PCC 1302. These messages are processed for display by the HMI or InPower, or be retransmitted as a ModBus or
PCCNET message.
Intake Manifold Temperature, Engine Oil Temperature and Fuel Rate are not available for display on the HMI211, but they are available for viewing on InPower or over the ModBus network.

PMG and Self Excitation
The PCC1302 switches the positive side of the incoming excitation source and sends a portion (measured in percent duty cycle) of it back to the field winding.
Zero Cross
% Duty Cycle From AVR Excitation Source Input Field Output
By adjusting how much we send to the field winding we can control the output voltage.
Visual 3-12 PCC 1302 Excitation Participant’s Text
The PCC 1302 provides a excitation DC output that varies in amplitude and on time. This is NOT a pwm signal and this is different from some other PCC controls, but it is very similar to some of the other
Cummins Generator Technologies automatic voltage regulators.
As can be noticed in the above image, if the on time increases, the voltage will increase. This relationship is called the “% Duty Cycle” and is found in the Monitor
>>Alternator >> Regulator section of
InPower and is labeled AVR%
13
As on time increases, excitation voltage increases.
Over Excitation is handled using reference to excitation on time – Duty Cycle.
Excitation Duty Cycle of 46% or 70vrms or more for 8 seconds will activate the over excitation fault.Over Excitation Protection
Voltage increase with increased Duty Cycle
Visual 3-13 PCC 1302 Over Excitation Participant’s Text
Over Excitation Protection
The PCC 1302 has built in algorithms that constantly calculates and monitors the output voltage, excitation voltage, excitation current, and Duty Cycle. If the control determines the excitation system is operating beyond safe limits, it will shut down the regulator output and engage the Over Excitation Fault.
This protection system is an improvement over using fuses or field breakers. With analog AVRs, these protection devices often contribute to AVR failures because when they open, it instantly removes the load from the AVR and internal voltages can spike high enough to damage the internal AVR components.
the thyristor (SCR) thereby extinguishing the field output. Therefore, the PCC 1302 does not experience internal voltage spikes.
