DESCRIPTION

SECTION 1 • GENERAL INFORMATION
ar
tM
an
ua
ls
.c
The DGC-500 Digital Genset Controller provides integrated engine-generator set control, protection, and
metering in a single package. Microprocessor based technology allows for exact measurement, setpoint
adjustment, and timing functions. Front panel controls and indicators enable quick and simple DGC-500
operation. Basler Electric communication software (BESTCOMS-DGC500-32) allows units to be easily
customized for each application. Because of the low sensing burden in the DGC-500, neither dedicated
potential transformers (PTs) nor current transformers (CTs) are required. A wide temperature-range liquid
crystal display (LCD) with backlighting can be viewed under a wide range of ambient light and
temperature conditions.
An event log retains a history of system events in nonvolatile memory. Up to 30 event types are retained
and each record contains a time stamp and the number of occurrences for each event.
Optional, multifunction generator protection guards against generator overvoltage, undervoltage, underfrequency, overfrequency, overcurrent, and phase imbalance. Each generator protection function has an
adjustable pickup and time delay setting. Sixteen inverse time curves enable the DGC-500 to offer
overcurrent protection in a variety of applications.
An optional, SAE J1939 interface provides high-speed communication between the DGC-500 and the
engine control unit (ECU) on an electronically controlled engine. This interface provides access to oil
pressure, coolant temperature, and engine speed data by reading these parameters directly from the
ECU. When available, engine diagnostic data can also be accessed.
FEATURES
DGC-500 Digital Genset Controllers have the following features.
lP
Resistant to high moisture, salt fog, humidity, dust, dirt, and chemical contaminants
Resistant to the entrance of insects and rodents
Suitable for mounting in any top mount enclosure
Suitable for controlling isolated generating systems or paralleled generating systems
Serial link communications and BESTCOMS software eases access to setup parameters
Compliant with National Fire Prevention Association (NFPA) Standard 110
Optional SAE J1939 interface provides high-speed communication with the ECU on electronically
controlled engines

SECTION 3 • FUNCTIONAL DESCRIPTION
.c
This section describes how the DGC-500 functions and explains its operating features. A detailed
description of each function block is provided in the paragraphs under the heading of DGC-500 Function
Blocks.

lP
To ease understanding, DGC-500 functions are illustrated in the block diagram of Figure 3-1. The
following paragraphs describe each function in detail.
Figure 3-1. Function Block Diagram
.E
lec
Power Supply
The internal, switch-mode power supply uses the applied battery voltage to generate operating power for
the internal circuitry of the DGC-500. The power supply accepts a nominal battery voltage of 12 or 24 Vdc
and has an operating range of 8 to 32 Vdc. Battery voltage is applied to terminals P20 (+) and P21 (–).
Battery Voltage Sensing
Voltage applied to the power supply is filtered and reduced to a suitable level for sensing by the
microprocessor.
Microprocessor
ww
w
The microprocessor controls the overall functionality of the DGC-500 and makes decisions based on
programming and system inputs.
Circuits relating to the microprocessor inputs are described in the following paragraphs.
Zero Crossing Detection
The zero crossing of A-phase to B-phase line voltage is detected and used to calculate the generator
frequency.

om
Analog-to-Digital Converter
.c
Scaled and conditioned signals representing the sensing voltage, sensing current, coolant temperature,
fuel level, oil pressure, and battery voltage are digitized by the microprocessor’s 10-bit analog-to-digital
converter. The digitized information is stored in random access memory (RAM) and used by the
microprocessor for all metering and protection functions.
Watchdog Timer
ar
tM
an
ua
ls
The watchdog timer monitors the firmware executed by the microprocessor. If the firmware ceases normal
operation, the watchdog timer will reset the microprocessor. After reset, the microprocessor will resume
normal operation if the condition that caused the watchdog reset is no longer present. If the condition is
still present, the unit will reset repeatedly until normal operation is resumed or until the watchdog count
reaches five. If the count reaches five, the unit will go to watchdog lockout mode. If a half-hour elapses
after the most recent reset and the watchdog count has not reached five, the watchdog count is cleared.
Once the unit enters the watchdog lockout mode, a power cycle is required to clear the lockout.
Voltage Sensing Inputs
Generator voltages applied to the voltage sensing inputs are scaled to levels suitable for use by the
internal circuitry. Voltage sensing configuration is menu-selectable.
The voltage sensing inputs accept a maximum voltage of 576 Vrms, line-to-line. Sensing voltage is
applied to terminals P23 (A-phase), P26 (B-phase), P29 (C-phase), and P30 (Neutral).
Current Sensing Inputs
Generator currents are sensed and scaled to values suitable for use by the internal circuitry. Isolation is
provided by internal current transformers (CTs).
DGC-500–X1 units accept a maximum current value of 1 Aac. DGC-500–X5 units accept a maximum
current value of 5 Aac. Sensing current is applied to terminals P10 and P11 (A-phase), P12 and P14 (Bphase), and P15 and P17 (C-phase).
Transducer Inputs
lP
Programmable transducer inputs give the DGC-500 user the flexibility to select the transducer to be used
in an application. Information about programming the transducer inputs is provided in Section 4,
BESTCOMS Software.
ca
Oil Pressure
tri
A current of less than 30 milliamperes is provided to the oil pressure transducer. The developed voltage is
measured and scaled for use by the internal circuitry. Oil pressure transducers that are compatible with
the DGC-500 include Isspro model R8919, Stewart-Warner models 279BF, 279C, 411K, and 411M, and
VDO models 360025 and 360811. Other senders may be used. BESTCOMS software allows for the
programming of sender characteristics. See Section 4, BESTCOMS Software for more information.
Oil pressure transducer connections are provided at terminals P13 and P19 (sender common).
.E
lec
Coolant Temperature
A current of less than 1.2 milliamperes is provided to the coolant temperature transducer. The developed
voltage is measured and scaled for use by the internal circuitry. Coolant temperature transducers that are
compatible with the DGC-500 include Isspro model R8959 and Stewart-Warner 334-P. Other senders
may be used. BESTCOMS software allows for the programming of sender characteristics. See Section 4,
BESTCOMS Software for more information.
Coolant temperature transducer connections are provided at terminals P18 and P19 (sender common).
Fuel Level
ww
w
A current of less than 5 milliamperes is provided to the fuel level transducer. The developed voltage is
measured and scaled for use by the internal circuitry. An open circuit or short circuit across the fuel level
transducer terminals will cause the DGC-500 to indicate a failed fuel level transducer. Fuel level
transducers that are compatible with the DGC-500 include Isspro model R8925. Other senders may be
used. BESTCOMS software allows for the programming of sender characteristics. See Section 4,
BESTCOMS Software for more information.
Fuel level transducer connections are provided at terminals P16 and P19 (sender common).

Speed Signal Inputs
The DGC-500 uses signals from the voltage sensing inputs and magnetic pickup input to detect machine
speed.
Voltage Sensing Inputs
.c
Generator voltage applied to the DGC-500 voltage sensing inputs is used to measure frequency and can
be used to measure machine speed.
Sensing voltage is applied to terminals P23 (A-phase), P26 (B-phase), P29 (C-phase), and P30 (Neutral).
Magnetic Pickup Input
ar
tM
an
ua
ls
The voltage received from the magnetic pickup is scaled and conditioned for use by the internal circuitry
as a speed signal source.
Magnetic pickup connections are provided at terminals P39 (+) and P40 (–).
Contact Input Circuitry
The DGC-500 has four contact sensing inputs: Emergency Stop and three programmable inputs.
Emergency Stop Input
This input accepts Form A, dry contacts. An open circuit at this continuously monitored input initiates an
emergency stop. An emergency stop removes operating power from all DGC-500 output relays.
Emergency stop contact connections are provided at terminals P35 and P37.
Programmable Inputs
Each programmable input (PROG INPUT1, PROG INPUT2, and PROG INPUT3) can be independently
configured as an auto transfer switch input, single-phase override input, low coolant level input, fuel leak
detection input, battery charger failure input, or an auxiliary input. By default, each programmable input is
disabled.
ca
lP
The programmable inputs accept normally open, Form A contacts. A contact is connected between a
programmable input and the negative side of the battery voltage. Through BESTCOMS software, each
programmable contact input can be assigned a name (eight characters, maximum) and configured as an
alarm input, a pre-alarm input, or neither. The default names for the inputs are AUX IN 1, AUX IN 2, and
AUX IN 3. When a programmable contact input is closed, the front panel display shows the name of the
closed input if it was programmed as an alarm or pre-alarm input. Alarm inputs are annunciated through
the Normal display mode screens of the front panel. Pre-alarm inputs are annunciated through the
Alternate display mode screens of the front panel. If neither is programmed, no indication is given.
Programming an input as neither is useful when a programmable input is used to close one of the DGC500's programmable outputs.
tri
Connections for the programmable inputs are provided at terminals P2 (PROG INPUT1), P3 (PROG
INPUT2), and P4 (PROG INPUT3). The negative side of the battery voltage (terminal P21) serves as the
return connection for the programmable inputs.

connector. The RS-232 connector serves as a communication interface for enhanced DGC-500 setup.
Communication requires a standard 9-pin serial communication cable connected between the RS-232
communication port and a PC operating with BESTCOMS-DGC500-32. BESTCOMS is a Windows®
based communication software package that is supplied with the DGC-500. A detailed description of
BESTCOMS is provided in Section 4, BESTCOMS Software.
SAE J1939 Interface (Optional)
ca
A Controller Area Network (CAN) is a standard interface that allows communication between multiple
controllers on a common network using a standard message protocol. DGC-500 controllers with a style
number of XXJX have a CAN interface that supports the SAE J1939 message protocol.
tri
Applications using an engine-driven generator set controlled by a DGC-500 may also have an Engine
Control Unit (ECU). The CAN interface allows the ECU and DGC-500 to communicate. The ECU reports
operating information to the DGC-500 through the CAN interface. Operating parameters and diagnostic
information, if supported by the ECU, are decoded and displayed for monitoring.
ww
w
.E
lec
The primary use of the CAN interface is to obtain engine operating parameters for monitoring speed,
coolant temperature, oil pressure, coolant level, and engine hours without the need for direct connection
to individual senders. Table 3-1 lists the ECU parameters and Table 3-2 lists the engine configuration
parameters supported by the DGC-500 CAN interface. These parameters are transmitted via the CAN
interface at preset intervals. The columns labeled Update Rate show the parameter transmission rates.
This information can also be transmitted upon user request.

Table 3-3. Diagnostic Information Obtained Over the CAN Interface
DTCs are reported in coded diagnostic information that includes the Suspect Parameter Number (SPN),
Failure Mode Identifier (FMI), and Occurrence Count (OC). All parameters have an SPN and are used to
display or identify the items for which diagnostics are being reported. The FMI defines the type of failure
detected in the subsystem identified by an SPN. The reported problem may not be an electrical failure but
a subsystem condition needing to be reported to an operator or technician. The OC contains the number
of times that a fault has gone from active to previously active.
Horn Output
This output connects to a user-supplied audible signal device. A change in operating status or an alarm
condition energizes the horn output continuously and a pre-alarm condition pulses the horn output on and
off. The annunciation continues until the condition subsides or until the front-panel Alarm Silence
pushbutton is pressed.
The horn output supplies 15 mAdc maximum at the lesser of 24 Vdc or the battery voltage level. A horn
compatible with the DGC-500 is available from Basler Electric as part number 29760. Horn output
connections are located at terminals P24 (+) and P25 (–).
Output Contacts
ca
lP
All output contacts are electrically isolated from each other and from the DGC-500 internal circuitry.
Output contact operation is controlled by the operating mode of the DGC-500 and the system. The output
contacts are also affected by the status of the Emergency Stop contact input. When the Emergency Stop
contact input is open (emergency stop condition), all output contacts open. When the Emergency Stop
contact input is closed, all output contacts operate normally.
Five output contacts are available: Pre-Start, Engine Crank, Fuel Solenoid, and two Programmable output
contacts.
tri
Pre-Start
.E
lec
This output closes to energize the engine glow plugs. The Pre-Start output can be programmed to close
up to 30 seconds prior to engine cranking. The Pre-Start output can also be programmed to open upon
engine startup or remain closed as long as the engine is operating.
Crank
This output closes when engine cranking is initiated by the DGC-500. The length of time that the contacts
remain closed is determined by the cranking style selected (either continuous or cycle). Cranking
continues until the magnetic pickup or generator frequency indicates that the engine has started.
Fuel

Power-Up Sequence
ca
Embedded software controls all aspects of DGC-500 operation. DGC-500 software controls power-up
initiation, HMI configuration, engine cranking, contact input monitoring, fault detection and annunciation,
system parameter monitoring, output contact control, and communication.
.E
lec
tri
When battery power is applied, the DGC-500 initiates a power-up sequence. During power-up, DGC-500
memory is checked and the LCD displays the embedded software version followed by a prompt to set the
real-time clock. Then, all configuration data stored in nonvolatile EEPROM (electronically erasable
programmable read-only memory) is brought into main memory and the DGC-500 begins operating in
Normal mode. When operating in Normal mode, all enabled functions are active and all inputs are
monitored.
NOTE
w
The run-time counter and maintenance timer values are updated in volatile
memory once per minute. Updated values are saved to nonvolatile memory when
the Auto/Off/Run mode of operation is changed. Additionally, while the engine is
running, the run-time counter value is saved to nonvolatile memory every 15
minutes. If the battery power source fails during DGC-500 operation, these
values are not updated and the changes made after the last save operation to
nonvolatile memory are irretrievably lost.
ww
Cranking
The DGC-500 can be programmed for either continuous engine cranking or cycle engine cranking.
3-8
DGC-500 Functional Description

Continuous Cranking
.c
If desired, engine cranking can be delayed from zero to 30 seconds after initiating engine startup. When
continuous engine cranking is initiated, cranking is sustained for a user-adjustable period of one to 60
seconds. A crank disconnect limit setting (10 to 100% of nominal engine speed) selects the desired
engine speed above which cranking is terminated.
Cycle Cranking
ar
tM
an
ua
ls
If desired, engine cranking can be delayed from zero to 30 seconds after initiating engine startup. When
cycle engine cranking is initiated, five to 15 seconds of cranking is followed by an equal number of
seconds of rest. A maximum of seven cranking cycles (five cycles for NFPA compliant units) are allowed
by the DGC-500. A crank disconnect limit setting (10 to 100% of nominal engine speed) selects the
desired engine speed above which cranking is terminated.
Pre-Alarms
A pre-alarm is annunciated when a condition programmed to trigger a pre-alarm is met. When a pre-alarm
condition exists, the front panel Alarm indicator flashes on and off and the Horn output (if enabled through
BESTCOMS) alternates between an energized and de-energized state. The audible alarm is reset by
pressing the front panel Alarm Silence pushbutton.
Active pre-alarms for oil pressure, fuel level, coolant temperature, and battery voltage are displayed on
the main display of the LCD. The LCD annunciates an active pre-alarm by alternating between the current
parameter value and a blacked-out field for that value. All other pre-alarms are displayed in sequence
through the alternate mode display.
Each DGC-500 pre-alarm is described in the following paragraphs.
Low Oil Pressure
A low oil pressure pre-alarm occurs when the engine oil pressure decreases below the setpoint
programmed in BESTCOMS. The low oil pressure pre-alarm has a setting range of 3 to 150 psi or 20 to
1,035 kPa. A 10-second activation time delay prevents low oil pressure annunciation during engine
startup.
Low Fuel
ca
High Coolant Temperature
lP
A low fuel pre-alarm occurs when the fuel level decreases below the setpoint programmed in
BESTCOMS. The low fuel pre-alarm has a setting range of 10 to 100 percent.
tri
A high coolant temperature pre-alarm occurs when the engine coolant temperature exceeds the setpoint
programmed in BESTCOMS. The high coolant temperature pre-alarm has a setting range of 100 to 280°F
or 38 to 138°C. A 60-second activation time delay prevents high coolant temperature annunciation during
system startup.
Low Coolant Temperature
.E
lec
A low coolant temperature pre-alarm occurs when the engine coolant temperature decreases below the
setpoint programmed in BESTCOMS. The low coolant temperature pre-alarm has a setting range of 50 to
100°F or 10 to 38°C.
Battery Overvoltage
A battery overvoltage pre-alarm occurs when the battery overvoltage pre-alarm function is enabled in
BESTCOMS and the battery voltage level exceeds 30 Vdc for 24 Vdc systems or 15 Vdc for 12 Vdc
systems.
Low Battery Voltage
ww
w
A low battery voltage pre-alarm occurs when the battery voltage decreases below the low battery voltage
setpoint for the duration of the low battery voltage time delay setting. Both settings are made in
BESTCOMS. The low battery voltage setpoint has a setting range of 12 to 24 Vdc for 24 Vdc systems
and 6 to 12 Vdc for 12 Vdc systems. The low battery voltage time delay has a setting range of 1 to 10
seconds.
Weak Battery Voltage
A weak battery voltage pre-alarm occurs when the battery voltage decreases below the weak battery
voltage setpoint for the duration of the weak battery voltage time delay setting. Both settings are made in
BESTCOMS. The weak battery voltage setpoint has a setting range of 8 to 16 Vdc for 24 Vdc systems

Maintenance Interval
.c
A maintenance interval pre-alarm occurs when the DGC-500 maintenance timer counts down to zero from
the maintenance interval setting programmed in BESTCOMS. The maintenance interval duration has a
setting range of zero to 5,000 hours.
Battery Charger Failure
ar
tM
an
ua
ls
A battery charger failure pre-alarm occurs when one of the three DGC-500 programmable contact inputs
detects a contact closure due to a battery charger failure. In order for a battery charger failure pre-alarm
to occur, the battery charger failure pre-alarm function must be enabled in BESTCOMS and one of the
three programmable inputs must be programmed as a battery charger failure pre-alarm input. Refer to
Section 4, BESTCOMS Software for information about configuring the programmable contact inputs.
Fuel Level Sender Failure
A fuel level sender failure pre-alarm occurs when an open circuit or short circuit is detected across the
DGC-500 fuel level transducer terminals and a fuel level sender failure is programmed in BESTCOMS to
cause a pre-alarm.
MPU Failure
An MPU (magnetic pickup) failure pre-alarm occurs when MPU-GEN is selected as the generator speed
signal source, the MPU signal is lost, and the Global Sender Failure Alarm time delay expires.
Active DTC
When CAN and DTC support are both enabled, an “active DTC” pre-alarm may be enabled (through
BESTCOMS) to announce the presence of a condition that is causing a DTC to be sent from the ECU to
the DGC-500.
CAN Failure
lP
A CAN failure annunciation may be enabled only when the CAN interface is enabled. The CAN interface
is enabled through BESTCOMS. When configured to alarm, annunciation occurs when CAN
communication stops due to a lost connection between the DGC-500 and ECU, or an ECU malfunction. If
CAN communication is lost and the annunciation is a pre-alarm, a screen stating the pre-alarm will
appear in the Alternate Display menu. This screen will be viewable only when the pre-alarm is active.
ca
Audible Alarm
Alarms
tri
A pre-alarm is annunciated through the DGC-500 Horn output when the audible alarm feature is enabled
in BESTCOMS. When the audible alarm is enabled, a pre-alarm condition causes the horn output to
alternate between an energized and de-energized state.
.E
lec
An alarm is annunciated when a condition programmed to trigger an alarm is detected. When an alarm
condition exists, the front panel Alarm indicator lights, the Horn output energizes, and the cause of the
alarm is displayed on the LCD.
An alarm condition stops the engine by opening the Fuel output contact.
Each DGC-500 alarm is described in the following paragraphs.
Low Oil Pressure
A low oil pressure alarm occurs when the engine oil pressure decreases below the low oil pressure alarm
setpoint for the duration of the low oil pressure time delay setting. Both settings are made in BESTCOMS.
When a low oil pressure alarm occurs, the LCD indicates LOW OIL PRESSURE and the current low oil
pressure alarm setting. A 10-second activation time delay prevents low oil pressure annunciation during
engine startup.
w
The low oil pressure setpoint has a setting range of 3 to 150 psi or 20 to 1,035 kPa and the low oil
pressure time delay has a setting range of 5 to 15 seconds.
Low Fuel Level
ww
A low fuel level alarm occurs when the fuel level decreases below the setpoint programmed in
BESTCOMS. When a low fuel level alarm occurs, the LCD indicates LOW FUEL LEVEL and the current
low fuel level alarm setting.
3-10
DGC-500 Functional Description
9355400990 Rev G
om
The low fuel level setpoint has a setting range of zero to 100 percent.
High Coolant Temperature
.c
A high coolant temperature alarm occurs when the coolant temperature exceeds the setpoint
programmed in BESTCOMS. When a high coolant temperature alarm occurs, the LCD indicates HIGH
COOLANT TEMP and the current high coolant temperature setting. A 60-second activation time delay
prevents high coolant temperature annunciation during system startup.
The high coolant temperature setpoint has a setting range of 100 to 280°F or 38 to 138°C.
Overspeed
Loss of Generator Voltage
ar
tM
an
ua
ls
An overspeed alarm occurs when the engine speed exceeds the overspeed setpoint for the duration of
the overspeed time delay. Both settings are made in BESTCOMS. When an overspeed alarm occurs, the
LCD indicates OVERSPEED and the current overspeed setting.
The overspeed setpoint has a setting range of 105 to 140 percent and the overspeed time delay has a
setting range of zero to 500 milliseconds.
A loss of generator voltage alarm can occur only when the loss of generator voltage alarm is enabled in
BESTCOMS. When the sensed generator voltage decreases below 1.5 Vac for the duration of the global
sender failure alarm time delay, a loss of generator voltage alarm occurs. The global sender failure alarm
time delay is adjustable from 1 to 10 seconds.
Oil Pressure Sender Failure
An oil pressure sender failure alarm occurs when the DGC-500 oil pressure transducer input senses a
sender failure for the duration of the global sender failure alarm time delay. The oil pressure sender
failure alarm is enabled and the global sender failure alarm time delay is set in BESTCOMS.
Coolant Temperature Sender Failure
lP
A coolant temperature sender failure alarm occurs when the DGC-500 coolant temperature transducer
input senses a sender failure for the duration of the coolant temperature alarm delay time. The coolant
temperature sender failure alarm is enabled and the coolant temperature alarm delay is set in
BESTCOMS. The coolant temperature alarm delay is adjustable from 5 to 30 minutes in 5 minute
increments.
Speed Source Failure
ca
A speed source failure can occur for either of two conditions. If MPU (magnetic pickup) is selected as the
generator speed signal source and the MPU signal is lost, a speed source failure alarm will occur. If GEN
FREQ (generator frequency) is selected as the generator speed signal source and a loss of generator
frequency is detected, a speed source failure alarm will occur.
tri
CAN Failure (If Equipped)
.E
lec
A CAN failure annunciation may be enabled only when the CAN interface is enabled. The CAN interface
is enabled through BESTCOMS. When configured to pre-alarm, annunciation occurs when CAN
communication stops due to a lost connection between the DGC-500 and ECU, or an ECU malfunction. If
CAN communication is lost and the annunciation is configured as an alarm, then a normal alarm
sequence will occur, including a CANBUS FAILURE message that appears on the HMI display.
Real-Time Clock
The real-time clock supplies time and date information to the event log for the time stamping of events.
Clock data is held in volatile memory; clock settings are lost when DGC-500 operating power is removed.
When DGC-500 operating power is restored, the DGC-500 prompts the user to set the real-time clock.
ww
w
The DGC-500 keeps time in 24-hour mode and uses the HH:MM:SS format. The date format is
MM/DD/YYYY. Adjustment for daylight saving time can be enabled or disabled. Clock settings may be
viewed and entered in BESTCOMS or at the front panel HMI.
Generator Run Statistics
The DGC-500 compiles statistics for both individual generator run sessions and the cumulative total of all
generator run sessions. Generator run statistics are stored in DGC-500 nonvolatile memory and
displayed on the Run Statistics screen of BESTCOMS. When the DGC-500 and/or genset are
commissioned, a date is entered for the DGC-500 to use as a starting point for tracking generator run
9355400990 Rev G
DGC-500 Functional Description

om
statistics. The logs for session run and cumulative run statistics track loaded run hours, unloaded run
hours, and total run hours. Additionally, the cumulative run statistics log tracks the number of engine
starts and the number of hours remaining until scheduled maintenance.
Event Log
.c
The event log maintains a history of system events in DGC-500 nonvolatile memory and displays the
event record on the Event Log screen in BESTCOMS. System events are categorized by the event log
into event types. The event log capacity is 30 event types.
ar
tM
an
ua
ls
Each event type in the log contains an event identifier label, the number of occurrences for the event, and
the time stamp of the most recent event occurrence. The time stamp displayed is user-selectable and can
be real-time clock data or the elapsed engine hours.
When an event type is logged, it occupies one entry (or row) in the log. If the same event type is logged
again, it still only occupies one entry in the log. However, the log entry is updated with the number of
occurrences and the Last Date/Time column is updated with the time stamp of the last occurrence.
If the event log contains the maximum of 30 event types and a new event type is logged, the oldest event
type in the log is overwritten with the new event type.
The event types monitored by the event log are listed below.

An undervoltage annunciation can be user-selected to trigger a pre-alarm (warning) or alarm (shutdown).
An undervoltage annunciation can also be user-configured to close one or both of the programmable
outputs.
When a Single-Phase Override contact input is received, the DGC-500 automatically switches from the
three-phase undervoltage settings to the single-phase undervoltage settings.
Frequency (81)
Two sets of frequency settings are provided: one for underfrequency (81U) protection and one for
overfrequency (81O) protection.
When the generator frequency decreases below the 81U pickup setting for the duration of the 81U time
delay, an underfrequency condition is annunciated. When the generator frequency increases above the
81O pickup setting for the duration of the 81O time delay, an overfrequency condition is annunciated. For
50/60 hertz sensing, the 81U and 81O functions have a setting range of 45 to 65 hertz. For 400 hertz
sensing, the 81U and 81O functions have a setting range of 360 to 440 hertz. The time delay for the 81U
and 81O functions has a setting range of 0 to 30 seconds.
A voltage-based inhibit setting prevents an 81U trip from occurring during an undervoltage condition
associated with system startup. The voltage-based inhibit function has a setting range of 70 to 576 Vac.
lP
Underfrequency and overfrequency conditions can be user-selected to trigger a pre-alarm (warning) or
alarm (shutdown). An underfrequency and/or overfrequency condition can also be user-configured to
close one or both of the programmable outputs.
Overcurrent (51)
ca
Two sets of overcurrent settings are provided: one for three-phase generator connections and one for
single-phase generator connections.
.E
lec
tri
When any of the phase currents increase above the 51 pickup setting for the duration of the 51 time
delay, an overcurrent condition is annunciated. Controllers with 1 A current sensing (style X1XX) have an
overcurrent pickup range of 0.18 to 1.18 Aac. Controllers with 5 A current sensing (style X5XX) have an
overcurrent pickup range of 0.9 to 7.75 Aac. The overcurrent time delay is controlled by a curve setting
and time dial setting. The curve setting can be set at F, Fixed, or one of 16 inverse timing characteristic
curves can be selected. When the F, Fixed curve setting is selected, the time dial setting (adjustable from
0 to 30 seconds) determines the overcurrent time delay with no regard to the generator current level.
When one of the 16 inverse timing characteristics curves selected, the time dial setting (adjustable from a
multiplier of 0 to 9.9) along with the level of measured generator current determines the overcurrent time
delay.
The available characteristic curves is listed below and illustrated in Appendix A, Time Overcurrent
Characteristic Curves.

ENGINE CONTROL UNIT (ECU) SUPPORT
The following paragraphs describe the support provided by the DGC-500 for operation with an engine
control unit (ECU).
Enabling ECU Support
ca
lP
To enable ECU support, the user must access the SYST menu in BESTCOMS and select Enable ECU
Support under the box entitled CANBus/J1939 Interface. After resending the settings, the DGC-500 will
ignore the analog inputs for coolant temperature, oil pressure and engine speed, and it will no longer
calculate engine run-time. Once the DGC-500 establishes communication with an ECU, the engine runtime, coolant level, coolant temperature, oil pressure, and engine speed will be updated with the ECU
values.
NOTE
tri
With Enable ECU Support selected, there is a non-programmable Coolant Level
Sender Fail alarm that can annunciate when the engine is either off or running.
.E
lec
Coolant level is metered and displayed only when Enable ECU Support is
selected in BESTCOMS.
ECU Constraints
An external source cannot always turn the engine off without removing power from the ECU. Removing
power from the ECU is the only way to remove fuel from the engine and shut it down. Different ECU
manufacturers have their own rpm setpoints for reapplying fuel to an engine. For example, if the ECU is
powered up and the engine is still spinning above 60 rpm, the ECU may automatically turn the fuel on.
ww
w
Not being able to stop the engine without removing power from the ECU causes two problems. The first
problem is that the only way to stop the engine is to turn the ECU off and wait for the engine speed to
decrease below 60 rpm before reapplying ECU operating power. Otherwise, the engine will resume
running. The second problem is that while the ECU is off, you can no longer meter and update coolant
level, coolant temperature, oil pressure, and engine speed values, effectively disabling features like low
coolant temperature alarm/pre-alarm and crank control.

The DGC-500 Solution
The DGC-500 resolves ECU constraints by using four user-programmable timers that are accessed
through BESTCOMS. Each timer setting is described in the following paragraphs.
.c
Pulse Cycle Time. This timer setting establishes the time, in minutes, that the DGC-500 waits before
pulsing the ECU again.
Response Timeout. This timer setting defines the length of time, in seconds, that the DGC-500 attempts
communication with the ECU when the DGC-500 is in the Pulsing state or Connecting state.
ar
tM
an
ua
ls
Settling Time. This timer setting controls the length of time, in tenths of seconds, that the DGC-500
gathers data after connecting to the ECU during the Pulsing state. This allows all metered values to be
sent and ramped up to their steady state values. Metered values are sent out by the ECU at different
rates as designated by the J1939 protocol. ECU values initially sent are low and the ECU takes time to
average out its own data values.
Engine Shut Down. This timer setting determines the length of time, in seconds, that the DGC-500
remains disconnected from the ECU when going from Running to Shutdown before starting the first pulse.
This timer should allow enough time for the engine to slow down so that when the DGC-500 pulses, the
ECU will not restart the engine.
Alarms and Pre-Alarms
If ECU communication is not established during the Connecting state or is lost during the Pre-Start,
Cranking, Resting, Running, or Cooling states, then a non-programmable ECU Communications Fail
alarm is annunciated. If the last pulse was unsuccessful (ECU communication was not established), then
the ECU Communications Fail pre-alarm will annunciate. The pre-alarm is checked only after the Pulsing
state and is annunciated only during the Ready state.
To clear Coolant Level alarms when ECU power support is needed, the user must first correct the
condition causing the alarm and then pulse the ECU to update the data. The user may pulse the ECU
remotely through BESTCOMS or locally by pressing the front panel pushbuttons in the ordered sequence
of Auto, Off.

ca
Because there is no external fuel solenoid to connect to, the fuel solenoid relay has been designated to
control ECU operating power. For example, Detroit Diesel's ECU applies fuel to the engine only after
engine speed rises above 60 rpm. The following timers control the fuel solenoid relay when the engine is
not running.
NOTE
When ECU support is enabled during Pre-start and Resting, the fuel solenoid is
closed.
Display Values (ECU Support Enabled)
The ECU is able to give the DGC-500 in-depth information about the values it sends. This makes it
possible for the DGC-500 to display accurate information when metering these values from the ECU.
After successfully pulsing the unit, the last values gathered when powering-off the ECU are displayed
until the next pulse. The following is a list of display values:
•
•
•
•
ww
w
Value - the actual value is displayed if the last pulse was successful or the engine is running.
No Communications (abbreviated as NC) - displayed if the last pulse was unsuccessful.
Not Applicable (abbreviated as NA) - the ECU does not monitor this data value.
ECU Data Not Sent (abbreviated as NS) - data was not sent in the time designated by the J1939
protocol.
• Sender Failure (abbreviated as SF) - the ECU has determined a sender failure for that metered value.

ECUs with an External Fuel Solenoid
.c
The DGC-500 supports ECUs that are able to cut-off fuel from the engine without powering the ECU off.
The DGC-500 requests engine run-time every minute to keep the ECU from going into a sleep mode.
After the Pulse Cycle Timer expires, the DGC-500 checks whether ECU communication exists. If so, the
DGC-500 will not pulse the ECU. The same goes for Connecting, except that the DGC-500 remembers if
it skipped the Connecting state. If it did, then the DGC-500 will also skip the Engine Shutting Down state
when it stops the engine.
ar
tM
an
ua
ls
For ECUs that have an external fuel solenoid, it is recommended that the Engine Shut Down timer be set
to its minimum value. This ensures that, if the DGC-500 temporarily loses power while running, the unit
will go straight into the Run state and go to the Shutting Down state when the unit goes to Off. It is also
recommended that the Response Timeout Timer be set to its minimum value in order to set the ECU
Communications Fail pre-alarm as soon as possible.
The HMI screens shown in Figure 3-15 are displayed if the last attempt to pulse the ECU for an
information update was unsuccessful.
Figure 3-15. Screens Shown Following Unsuccessful Information Update from ECU
STATE MACHINES
lP
A state machine is any device that stores the status of something at a given time. An input change can
change the status and/or cause an action or output to occur for any given change. A finite state machine
can be used to solve problems and describe the solution for system maintainers. State machine
illustration methods range from simple tables to graphically animated illustrations.

through BESTCOMS. However, for clarity, the term AUTO will not be used in this section. Auto-Run
and Auto-Off will be used instead. Auto-Run means the unit is in Auto while the automatic transfer
switch (ATS) is closed, or the user started the engine remotely through BESTCOMS. Auto-Off means
the unit is in Auto while the ATS is open, or the user stopped the engine remotely through
BESTCOMS. The system configuration settings for the DGC-500 are Run, Off, Auto-Run and AutoOff.
• If BESTCOMS remotely started the engine before a reset occurred or the system configuration goes
to Off, then the Remote Start setting in BESTCOMS is set to Stop.
• If ECU support is enabled when the engine is running and the system configuration goes to Off, then
the unit will go to the Shut Down state. Otherwise, it will transition to the Ready state and pulse the
ECU.
• If ECU support is disabled and system configuration goes to Off, then the unit will always transition to
the Ready state.
Operating States
The DGC-500 supports 11 operating states. Each operating state is illustrated by a flowchart later in this
section.

• Restart/Power-Up. The initial state.
• Ready. The DGC-500 is in the Off or Auto-Off mode.
• Pulsing. ECU Only—pulses (momentarily powers up) the ECU for updated information.
• Connecting. ECU Only—the system configuration just changed to Run or Auto-Run.
• Pre-Start. Closes the pre-start relay or pauses the DGC-500 while it is not safe to crank.
• Cranking. Cranks the engine until it is above the crank disconnect speed.

Resting. Occurs between crank cycles and does not crank the engine.
Running. The unit is now running and no longer cranking.
Cooling. Cool down running engine if a load is or was applied when going to Auto-Off mode.
Shutting Down. ECU Only—wait for engine to stop rotating before "pulsing".
Alarm. Alarm was triggered, wait for the alarm to clear.

State Transitions
Criteria used for deciding state transitions are based on the following input events.
System Configuration (Run, Off, in Auto with ATS closed, in Auto with ATS open)
Analog/ECU sender data (example: Engine Speed)
Programmable auxiliary inputs
Switch data (Coolant Level Switch, ATS, Emergency Stop Button)
ECU-specific data (example clearing/requesting diagnostics)
Various programmable timers (run-time, cycles, delays, time-out length)
Programmable I/O settings
Alarm settings (thresholds, enabling and timers)
Other settings selectable through BESTCOMS.

Input events are used in deciding the following output events.
• Output relays on the DGC-500 control the generator and other devices connected to the DGC-500.
• LED output is controlled by the system configuration setting, active alarm/pre-alarms, and by the
supplying load criteria.
• The LCD is controlled by the value of data being displayed, the state of the DGC-500, and by the
viewing mode (Normal, Alternate Display, ECU Parameters, or Menu).
• The horn (or buzzer) is controlled by the Alarm Silence, Run, or Off pushbuttons, and by the Alarm
and Pre-Alarm conditions.
Normal Program Control
.E

lP
If an engine does not have an ECU, then ECU Support should be disabled so that the DGC-500 uses
analog sender data. An engine with ECU support disabled or ECU support enabled with a constant power
supply and accessible fuel solenoid will follow the normal program control flowchart of Figure 3-16.
Figure 3-16. Normal Program Control Diagram
ECU Power Support Program Control
ww
w
If an engine has an ECU, then ECU support should be enabled so that the DGC-500 uses sender data
transmitted from the ECU over the J1939 interface. If the engine can be shut down only by powering off
the ECU, then the genset will need ECU power support enabled. An engine with ECU support enabled
and a need for ECU power support through the fuel solenoid will follow the ECU power support diagram
of Figure 3-17.

NOTE
ECU power support is not a selectable option. The DGC-500 will decide between
using the fuel solenoid output relay or controlling the fuel to provide ECU power
support. This is derived through the following method.
ar
tM
an
ua
ls
After the Pulse Cycle timer expires, the DGC-500 checks to see if ECU
communication is active. If so, then the DGC-500 will not pulse the ECU. The
same goes for Connecting, except the DGC-500 remembers if it skipped the
Connecting state. If it did, then it will also skip the Engine Shutting Down state
when the DGC-500 stops the engine.

Initial State - Power Up/Reset
tri
ca
This state begins after cycling power to the DGC-500, or after a software reset (i.e. a watchdog timeout)
has occurred. The unit will stay in reset for a short time. During this time, the firmware version number
appears on the front panel LCD and the DGC-500 averages out enough data counts to calculate accurate
analog data. During the Power Up/Reset state, if the previous system configuration was Run or Auto-Run
with the ATS closed and ECU support enabled, the fuel solenoid will close. This works to keep the engine
running if the unit temporarily losses power, and to gather engine speed data from the ECU to determine
if it should go to Off or stay in Run.
.E
lec
After a short time, the old system configuration from the last time the unit was not in reset is checked. If
the old system configuration was set to Run or Auto-Run with the ATS closed, then the engine speed is
checked against Crank-Disconnect (the rpm value used in deciding when to disengage the starter).
If engine speed is above Crank-Disconnect, then the Power Up/Reset state goes to the Running state.
If the speed is below Crank-Disconnect, the DGC-500 goes to the Ready state and immediately pulses
the ECU (if ECU support is enabled). If the previous system configuration was set to RUN, the System
configuration will be set to OFF. If the previous system configuration was set to Auto-Run (with the ATS
closed), the unit will still go to the Ready state. But then, the Ready state will transition into the Pre-Start
state and the Pre-Start state will eventually transition into the Cranking state, and so forth.

Ready State
The DGC-500 will be in Ready state when system configuration is Off/Auto-Off. If the system
configuration changes to Run/Auto-Run, then it will check to see if it needs to go to the Connecting, PreStart or Running state. If ECU support is selected and there is no ECU communication and the Pulse
Cycle Timer has expired, the Ready state will transition into Pulsing. The Pulse Cycle Timer can be set to
expire and force a Pulsing state. There are three ways to force a pulse.
• When a user logs on to a unit through BESTCOMS, if the unit is in Ready state, a pulse is forced to
update the internal variables used to meter ECU data.
• User attempts to clear DTCs from the ECU while the DGC-500 is in Ready (therefore, the ECU is
probably powered off).
• Manually force a pulse and update the internal variables. The user can do so in BESTCOMS or
locally pulse the ECU by pressing the front panel pushbuttons in the ordered sequence: Auto, Off.
Going to Off or Auto-Off
lP
If the DGC-500 is in the Connecting, Pre-Start, Resting or Cooling state when the unit goes to Off or
Auto-Off mode, then the state will transition to the Ready state. If ECU support is enabled, then the unit
will go to the Pulsing state immediately after transitioning to the Ready state.

The Pulsing State follows the sequence of events shown in Figure 3-20. The Pulsing state will
momentarily power up the ECU to update the DGC-500 internal variables. Once a connection is
established with the ECU, GATHERING DATA will appear on the LCD for the duration of the settling time.
During settling time, the unit processes any previous request for clearing DTCs from the ECU. The
Pulsing state always transitions to the Ready state unless the System configuration changes to Run/AutoRun. Then, it will transition to the Connecting state as a result of pulsing and will follow the ECU Power
Support diagram.

Connecting State
.E

lP
The Connecting State follows the sequence of events shown in Figure 3-21. If ECU communication is not
established by the time the Response Timeout expires, then the ECU Communications Failure Flag is set
to trigger the Alarm state. The Connecting state will power up the ECU. Once it reads the engine speed, it
checks if it is above Crank-Disconnect. If it is, then it will go to the Running state. Otherwise, it will go to
the Pre-Start state.
Figure 3-21. Connecting State Diagram
Pre-Start State
ww
w
This state will transition immediately to the Running state if the engine speed is above Crank-Disconnect.
Otherwise, it will wait here and close the Pre-heat relay for the pre-start time delay duration. If engine
speed is below Safe-To-Restart (the rpm value used in deciding when to engage the starter) and the Prestart time delay is expired or set to zero, then it will transition to the Cranking state. If engine speed falls in
the range between Crank-Disconnect and Safe-To-Restart, the state will pause and display NOT SAFE
TO CRANK along with the rpm value until the engine speed moves out of this range. If it is not safe to
crank and there is a pre-start time delay, then the Pre-heat relay will stay closed because it was closed
when it was waiting for the pre-start time delay to expire. If Pre-start time delay was set to zero, then the
Pre-heat relay was never closed. Therefore, it would remain open while it is not safe to crank. Figure 3-22
illustrates the Pre-Start state flowchart.

This state will engage the starter and transition to the Running state once engine speed is above crankdisconnect. During the Cranking state, the crank-type is checked. If the crank-type is Cycle Crank, then
the unit will transition to the Resting state when the crank time expires. If the crank-type is Continuous
Crank or is on the last crank cycle when the crank timer expires, then the Over-Crank flag is set to trigger
the Alarm state. If system configuration goes to Off/Auto-Off, the unit transitions to the Cooling state. In
the Cooling state, if ECU power support is needed, it will go to the Shutting Down state. The Cranking
state flowchart is illustrated in Figure 3-23.
Figure 3-23. Cranking State Diagram
Resting State
ww
w
If the rest period has ended, the unit will transition back to the Cranking state. If the State Machine is
following the ECU Power Support diagram, the Fuel Solenoid relay will be closed during the Resting
state. Thus, there is a possibility for the engine to start running during this state. Therefore, when the
ECU Power Support diagram is being followed, engine speed is checked to see if it is above crankdisconnect. If it is, the unit will transition into the Running state. Figure 3-24 illustrates the Resting State
flowchart.

If the System configuration changes to Off/Auto-Off, then the unit transitions to the Cooling state. If

is applied and removed from the engine. If Pre-Start Contact After Disconnect was enabled in
BESTCOMS, then during the course of this state, the Pre-Start relay will remain closed, otherwise it will
be opened. Figure 3-25 illustrates the Running State flowchart.

Cooling State
ww

This state is available only if the unit is in Auto/Off with an unexpired Cool-Down time or if the unit was in
the Cranking state when the unit went to Off. If system configuration changes back to Auto-Run, this state
will transition straight into the Running state since the engine should already be running while it is in the
Cooling state. If System configuration is Off, then the unit was either in the Cranking or Running state and
the unit will verify if it should go to the Ready or Shutting Down state. If there is a load applied to the
engine or one was applied and then removed, but the engine was not running long enough after it was
removed to expire the Cool-Down Time, the unit will stay in this state until the Cool-Down timer expires.
After the Cool-Down timer expires, if the unit is following the ECU Power Support diagram, the state will
transition to the Shutting Down state. Otherwise, it will go to the Ready state. Figure 3-26 illustrates the
Cooling state flowchart.

The Shutting Down State follows the sequence of events shown in Figure 3-27. If the Engine Shut Down
timer expires, the unit transitions to the Ready state. If system configuration changes back to Run/AutoRun, then this state will transition to the Connecting state, because if the unit is in a Shutting Down state,
it will continue to follow the ECU Power Support diagram.
Alarm State
tri
Figure 3-27. Shutting Down State Diagram
ww

.E
lec
All states except Reset can transition to the Alarm state. The State Machine frequently checks for alarms
and pre-alarms before running through each state. If an alarm is flagged in the initial alarm check, then
the unit goes into an Alarm state and waits there for the alarm to clear. If it is in Run/Auto-Run, then the
alarm can be cleared only by going to Off. When the alarm clears, the Alarm state will transition to the
Shutting Down state and then go to the Ready state. If ECU Support is enabled, the unit will go to the
Pulsing state immediately after transitioning to the Ready state. If in Off/Auto-Off, the alarm can be
cleared only if the alarm condition ceases or the user disables the alarm through BESTCOMS. Figure 328 illustrates the Alarm State flowchart.
NOTE
With ECU Support enabled, if an alarm was tripped by an ECU value, then it will
not clear. This is because in the Alarm state, the fuel solenoid is open, causing
the ECU to not have power to update the internal variables. To clear an alarm in
this event, the user must remotely place the unit in Off mode through
BESTCOMS or go from Auto-Off to Off via the front panel HMI to force a pulse of
the ECU.

For J1939 applications, the interface between the DGC-500 and ECU is configurable. First, the output
contact used to power up the ECU (for non-continuously powered ECU applications) is selectable.
Second, periodic communication with the ECU (also referred to as pulsing the ECU) may be disabled if
the application requires it. Third, the timers associated with pulsing the ECU are programmable. The
settings used to configure the ECU interface are adjusted through the ECU Control dialog box. This
dialog box is accessed by clicking Configure on the menu bar and clicking ECU Control. The ECU
interface settings of the ECU Control dialog box are shown in Figure 4-27 and described below.
.E

where the ECU is not continuously powered. If
the pre-start contact is selected, the fuel contact
will still close during cranking and running of the
genset to provide a separate indication that the
genset is running.
ECU Contact Control – Pulsing. In J1939
applications where the ECU is not continuously
powered, the DGC-500 will normally pulse the
ECU periodically to update its engine monitoring
data. For applications where this periodic
pulsing is not desired, this setting allows the
pulsing feature to be disabled.

is attempted with the ECU while the DGC-500 is in the Pulsing or Connecting state. The Response
Timeout setting range is 1 to 60 seconds.
PASSWORD PROTECTION
Password protection guards against unauthorized changing of DGC-500 settings. DGC-500 passwords
are case-sensitive. Three levels of password protection are available. Each level is described in the
following paragraphs.
•
•
•
Limited Access. This password level allows all DGC-500 settings to be read, but prevents any
changes to settings. The default, limited-access password is DGC.
Full Access. This password level allows all DGC-500 settings to be read and allows all settings
except Engine Runtime to be changed. The default, full-access password is DGC500.
OEM Access. This password allows all DGC-500 settings to be read and allows all settings to be
changed. It also allows the DGC-500 embedded firmware to be upgraded. The default, OEM-access
password is OEMLVL.
Changing Passwords
Passwords can be changed only after communication between
the PC and DGC-500 is established. Changes to passwords are
made through the Change Password dialog box. To access the
Change Password dialog box, click Communications on the
menu bar and click Change Password.
ca
lP
The content of the Change Password dialog box depends on the
password level used when accessing the dialog box. For
example, someone logged-in with a full-access password will be
able to change only the limited-access and full-access
passwords—not the OEM-access password. Figure 4-28 shows
the Change Password dialog box with all three access levels
shown.
tri
A password is changed by selecting the access level, entering
the new password, and then re-entering the new password to
confirm the entry.

AWG copper wire attached to the chassis ground terminal (P22) on the rear of
the controller.

Operating power from the battery must be of the correct polarity. Although
reverse polarity will not cause damage, the DGC-500 will not operate.
All DGC-500 terminals are located on the rear panel of the controller. There are three types of interface
terminals.
J1, a DB9 connector, is used as a temporary communication interface with IBM compatible PCs.
J2, a five-terminal header, is an SAE J1939 interface used for high-speed communication with a CANenabled engine control unit (ECU). J2 is enabled only on DGC-500 controllers with style numbers of F1J
or F5J.
All other connections consist of quarter-inch, quick-connect terminals. Amp part numbers 154718-3
(positive-lock receptacle) and 154719-1 (nylon housing) are the recommended components for making
connections at the quick-connect terminals. Wires performing common functions, such as voltage sensing
leads, should be grouped together.
All connections (except chassis ground and communication) should be made with wire no smaller than 14
AWG.

The RS-232 port on the rear panel uses a DB9 female connector. Figure 5-3 illustrates the pin
assignments of the communication port and Table 5-1 identifies the RS-232 connector pin functions. A
standard communication cable terminated with a DB9 male connector is used for PC interface with the
DGC-500 as shown in Figure 5-4.

Volvo Penta EDC III Applications
.c
Engines equipped with Volvo Penta EDC III controllers can receive engine control commands (such as
start and stop) from the DGC-500 through the SAE J1939 communication interface. To invoke this
feature, the EDC III must receive a J1939 message containing engine control information within one
second of waking (exiting sleep mode). If the EDC III does not receive an engine control message within
the prescribed time, it will enter the stand-alone mode and ignore any J1939 control messages. If this
occurs, the EDC III must be forced back into sleep mode by pressing the auxiliary stop pushbutton on the
engine or by momentarily disconnecting EDC power.
ar
tM
an
ua
ls
The interconnection diagrams of Figures 5-11 through 5-14 illustrate the DGC-500 and EDC III
connections that allow the DGC-500 to awaken the EDC III and start the engine, or simply acquire engine
status information. Wake-up of the EDC III is initiated by using the DGC-500 Fuel output contacts to apply
battery power to the EDC. To stop the engine, the DGC-500 issues a sleep command through the J1939
interface to the EDC III and opens the Fuel output contacts. This causes the EDC to stop the engine and
enter the sleep mode.
In order for the DGC-500 to communicate with the EDC III, two DGC-500 settings must be changed from
their default values.
• The J1939 address of the DGC-500 must be set at 17
• The engine start/stop configuration setting must be set for Volvo Penta

DGC-500 controllers, with version M or earlier hardware, may require additional protection for the contact
sensing inputs when used in environments with high levels of electrical noise. Additional protection can
be implemented by connecting external noise suppression diodes across the DGC-500 contact sensing
inputs. Schottky diodes, rated at 1 A, 1,000 Vdc or greater, are recommended. Figure 5-15 illustrates how
the noise suppression diodes are connected in a typical DGC-500 contact input application.

ls
The only preventative maintenance required on the DGC-500 is to periodically check that the connections
between the DGC-500 and the system are clean and tight. DGC-500 units are manufactured using stateof-the-art, surface-mount technology. As such, Basler Electric recommends that no repair procedures be
attempted by anyone other than Basler Electric personnel.
TROUBLESHOOTING
If you do not get the results that you expect from the DGC-500, first check the programmable settings for
the appropriate function. Use the following troubleshooting procedures when difficulties are encountered
in the operation of your genset control system.
Incorrect Display of Battery Voltage, Coolant Temperature, Oil Pressure, or Fuel Level
Step 1.
Verify that all wiring is properly connected. Refer to Figures 5-7 through 5-14.
Step 2.
Confirm that the SENDER COMM terminal (P19) is connected to the negative battery terminal
and the engine-block side of the senders. Current from other devices sharing this connection
can cause erroneous readings.
Step 3.
If the displayed battery voltage is incorrect, ensure that the proper voltage is present between
the BATT+ terminal (P20) and the SENDER COMM terminal (P19).
Step 4.
Verify that the correct senders are being used.
Step 5.
Verify that the correct sender curves are being used.
Step 6.
Ensure that the senders are operating properly.

The inverse time overcurrent characteristic curves provided by the DGC-500 (style xxx1 only) closely
emulate most of the common electromechanical, induction-disk, overcurrent relays sold in North America.
Within ±500 milliseconds of indicated operating
point.
Sixteen inverse time functions and one fixed time
function can be selected. Characteristic curves for
the inverse and definite time functions are defined
by the following equation:
TT =
TT
TR
MN − C
+B •D + K
Equation A-1
= Time to trip when M ≥ 1
= Time to reset if relay is set for integrating
reset when M < 1. Otherwise, reset is 50
milliseconds or less
= TIME DIAL setting (0.0 to 9.9)
= Multiple of PICKUP setting (0 to 40)
= Constants for the particular curve
This equation complies with IEEE Standard
C37.112-1996.
Table A-1 lists time characteristic curve
constants. See Figures A-1 through A-16 for
graphs of the characteristics.

Time Dial Setting Cross-Reference
N/A
Using Table A-3
ca
lP
Although the time characteristic curve shapes have been optimized for the DGC-500, the DGC-500 time
dial settings are not identical to the settings of electromechanical induction disk overcurrent relays. Table
A-3 helps you convert the time dial settings of induction disk relays to the equivalent setting for the DGC500.
tri
Cross-reference table values were obtained by inspection of published electromechanical time current
characteristic curves. The time delay for a current of five times tap was entered into the time dial
calculator function for each time dial setting. The equivalent DGC-500 time dial setting was then entered
into the cross-reference table.
.E
lec
If your electromechanical relay time dial setting is between the values provided in the table, it will be
necessary to interpolate (estimate the correct intermediate value) between the electromechanical setting
and the Basler Electric setting.
The DGC-500 has a maximum time dial setting of 9.9. The Basler Electric equivalent time dial setting for
the electromechanical maximum setting is provided in the cross-reference table even if it exceeds 9.9.
This allows interpolation as noted above.
Basler Electric time current characteristics are determined by a linear mathematical equation. The
induction disk of an electromechanical relay has a certain degree of non linearity due to inertial and
friction effects. For this reason, even though every effort has been made to provide characteristic curves
with minimum deviation from the published electromechanical curves, slight deviations can exist between
them.
ww
w
In applications where the time coordination between curves is extremely close, we recommend that you
choose the optimal time dial setting by inspection of the coordination study. In applications where
coordination is tight, it is recommended that you retrofit your circuits with Basler Electric electronic relays
to ensure high timing accuracy.
