SECTION 1 • GENERAL INFORMATION Description The DGC-2020 Digital Genset Controller provides integrated engine-genset 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-2020 operation. Basler Electric communication software (BESTCOMSPlus®) allows units to be easily customized for each application.
PAGE 22
Auto-Synchronizer An optional automatic synchronizer monitors the bus and generator voltages and supplies discrete raise/lower correction signals to synchronize the generator voltage, frequency, and slip angle with that of the bus. Contact Inputs and Output Contacts DGC-2020 controllers have one, dedicated emergency stop contact input and 16 programmable contact inputs. All contact inputs recognize dry contacts. The programmable inputs can be configured to initiate a pre-alarm or alarm.
PAGE 23
Dial-Out Modem The optional dial-out modem enables remote control, monitoring, and setting of the DGC-2020. When an alarm or pre-alarm condition occurs, the DGC-2020 can dial up to four telephone numbers, in sequence, until an answer is received and the condition is annunciated. RS-485 Port An optional RS-485 communication port uses the Modbus™ communication protocol and enables remote control and monitoring of the DGC-2020 over a polled network.

Mains Fail Transfer Functionality If mains fail transfer is enabled, the unit will run when the utility is determined to be bad, and will not stop until the utility has been determined to be good and the load has been transitioned to the utility. This mode is independent of the other self-starting modes. Run with Load Logic Element When the run with load logic element start input is energized, the unit will start, close its breaker, and take on load at the programmed load rate.
PAGE 80
• • Com Request - generated through a communication port using BESTCOMSPlus® or the front panel HMI. Logic Request - generated from BESTlogicPlus. The type of response given for a local request depends on the operating mode of the DGC-2020. RUN Mode When in RUN mode, the generator and mains breakers can be closed manually using contact inputs or the breaker buttons on the BESTCOMSPlus® Control screen.
PAGE 81
• The DGC-2020 must be in the process of initiating a breaker close Breaker close sources are: • • • • • The DGC-2020 itself when the automatic transfer (ATS) feature is enabled. The DGC-2020 itself when the Run with Load logic element receives a Start pulse in the programmable logic. The DGC-2020 itself when started from a Demand Start as part of demand start/stop and sequencing.
PAGE 82
Similar verification should be performed from the BUS VA and BUS VB terminals on the DGC-2020 to the Phase A and Phase B connections on the bus side of the breaker. It is also required that phase rotation is the same on both sides of the breaker for synchronization to be possible. NOTES When using the DGC-2020 synchronizer, it is recommended that local DGC2020 relay outputs be used for breaker closing commands to minimize the possibility of closures outside of desired breaker closing angles.

PAGE 115
Communications DGC-2020 communication settings include setup parameters for CANbus, ECU, modem, and RS-485 communication. CANbus Setup The DGC-2020 CANbus interface provides high-speed communication between the DGC-2020 and the A engine control unit (ECU) on an electronically controlled engine. When ECU support is enabled , the DGC-2020 will ignore the analog coolant temperature, oil pressure, and engine speed inputs and rely upon the ECU for these parameters.
PAGE 116
Not being able to stop the engine without removing ECU power 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 powering the ECU back on. Otherwise, the engine will take off running. The second problem is that while the ECU is off, you can no longer meter and update coolant level, coolant temperature alarm/pre-alarm, and crank control.

Programmable Curves for Overcurrent Protection Inverse overcurrent characteristics for trip and reset programmable curves are defined by Equation 4-1 and 4-2 respectively. These equations comply with IEEE Std C37.112-1996 - IEEE Standard InverseTime Characteristic Equations for Overcurrent Relays. The curve-specific coefficients are defined for the standard curves as listed in Appendix A, Time Overcurrent Characteristic Curves.

Loss of mains protection is only active when the generator is paralleled to the mains as indicated when the Parallel To Mains logic element is true in BESTlogicPlus. The protection is inhibited for five seconds after Parallel To Mains first becomes true so that transients from closing onto the mains will not cause false trips. To minimize false trips, loss of mains protection is disabled if any configured breakers are not closed.

open output. Likewise, if an external source closes the breaker, the DGC-2020 issues a breaker close output. N The dead bus close enable setting enables a machine to close its breaker onto a dead bus. This can be used to make sure only one machine can close onto a dead bus at a time, if desired, preventing multiple machines closing to the dead bus at the same time, potentially out of phase with each other. When this setting is disabled, a machine can only close onto a stable bus.

Closed transition override can be enabled through BESTlogicPlus Programmable Logic. When the Closed Transition Override element is set true, it forces a closed transition due to mains failure, overriding an open Mains Fail Transfer Type setting. Two logic elements are present in BESTlogicPlus Programmable Logic that can be used on a machine configured for mains fail operation to transition the load from the mains to the generator. These two logic elements are Mains Fail Test and Load Take Over.

A Mains Fail Transfer: Enable or Disable. This setting does not apply when generator frequency is 400Hz. Mains Fail Transfer Delay: Adjustable from 0 to 300 s in 1 s increments. This specifies the delay between detection of failed mains to initiation of the transfer to the generator. C Mains Fail Return Delay: Adjustable from 0 to 1,800 s in 1 s increments. This specifies the delay between detection of restored (stable) mains and initiation of the return from the generator back to the mains.

logic element in BESTlogicPlus Programmable Logic. When the Alternate Frequency Override is true, the scale factor setting serves as a multiplier for the pickup settings. For example, if a scale factor contact input is received by the DGC-2020 and the scale factor setting is 2.000, the pickup setting will be doubled (2.000 x PU). K Settings which are related to machine ratings can be set in either actual units voltage or in per unit values.

SECTION 7 • SETUP Introduction The following paragraphs provide information for DGC-2020 initial setup, setting up DGC-2020 programmable inputs and outputs, generator and bus breaker control, synchronizer, setting up a DGC2020 and LSM-2020 for a load sharing and kW control application, and mains fail transfer. DGC-2020 Initial Setup The DGC-2020 must be set up with parameters specific to the controlled machine in order to provide the desired machine control and protection.
PAGE 266
Communications If the engine has an ECU (electronic control unit) and the DGC-2020 is to communicate with it, the communications must be set up. CANbus Setup (Figure 7-2) 1. Enable ECU Support - Set to Enabled for the DGC-2020 to communicate with the ECU. 2. Enable DTC (Diagnostic Trouble Code) Support - If the ECU is a J1939 ECU, enable DTC support. If the engine ECU does not support it, no diagnostic trouble codes will be logged by the DGC-2020. 3.
PAGE 267
ECU Setup (Figure 7-3) 1. ECU Type - For most engines, select Standard. However, there are exceptions. If your engine is a Volvo, select Volvo-Penta. If you have an MTU MDEC, ADEC, ECU-7/ECU8, GM/Doosan, Cummins, or MTU Smart Connect, make the appropriate selection. Depending on the ECU type selected, some parameters may become enabled, allowing you to configure them for the specific engine. No modification of these parameters is required for the initial setup.

announced. If MPU-GEN is selected as rpm source, if the MPU input does not provide valid speed information, the DGC-2020 will switch to generator frequency as the rpm source, annunciate an MPU FAIL pre-alarm, and continue running. 7. NFPA Level - Set this if NFPA level 1 or 2 compliance is required for the machine. Figure 7-4.

accordingly. Refer to the appropriate paragraphs in Section 4, BESTCOMSPlus® Software, for additional information. 5. Oil Pressure Crank Disconnect - This setting provides an alternate method of determining conditions under which crank disconnect should occur. If the machine has no magnetic pick up (MPU) for rpm detection or a failed, MPU, and the DGC-2020 cannot read generator frequency to obtain rpm information, it will use oil pressure as criterion for crank disconnect.
PAGE 271
2. Generator PT Secondary Volts - This setting defines the voltage of the potential transformer (PT) secondary. The parameter must be less than 576 Vac because that is the maximum voltage that can be metered by the DGC-2020 voltage inputs. If no PT is used, leave this parameter at its default value. 3. Bus PT Primary Volts - This parameter defines the voltage of the potential transformer (PT) primary. If no PT is used, leave this parameter at its default value. 4.

Configuring Remote Contact Inputs on the CEM-2020 (See Figure 7-25) The settings of this screen are disabled unless the CEM-2020 (Contact Expansion Module) has been enabled as previously explained. Figure 7-25. Settings Explorer, Programmable Inputs, Remote Contact Inputs Screen For each contact input, configure the following parameters: 1. Alarm Configuration - Select an alarm configuration of None, Alarm, or Pre-Alarm.
PAGE 289
2. Activation Delay - This parameter defines how long the input remains on before any annunciation occurs. 3. Label Text - Enter descriptive text that signifies the use of the input. This text appears next to the input in BESTlogicPlus Programmable Logic and in the event log if the input is configured as an Alarm or Pre-Alarm. 4. Contact Recognition - Select whether the contact input should be recognized always, or only while the engine is running.
PAGE 290
2. Hysteresis (%) - Enter a value for the desired hysteresis for threshold detection. This helps prevent intermittent detection of thresholds. 3. Input Type - Select Voltage for 0-10 Vdc inputs or Current for 4-20 mA current inputs. 4. Arming Delay - The Arming Delay is the wait time after engine startup, before input monitoring begins. Set the arming delay to zero if constant monitoring is desired, including while the engine is not running.
PAGE 291
g. Under Threshold Alarm Configuration - Select None to disable, Status Only to make the threshold status available to BESTlogicPlus Programmable Logic, Pre-Alarm to annunciate a pre-alarm, or Alarm to annunciate an alarm. h. Over Threshold - This parameter defines when Status, Alarm, or Pre-Alarm annunciation is desired. i.
PAGE 292
5. Out-of-Range Alarm Type - An out-of-range condition occurs when the DGC-2020 detects that the input is outside of the normal range of what is detected for the RTD type. Primarily this provides indication of an open or shorted RTD circuit. If Alarm or Pre-Alarm is selected, annunciation will occur. If Status Only is selected, the status is available to BESTlogicPlus Programmable Logic but annunciation will not occur. 6.

line voltages contributed by each unit. This average voltage is proportional to the average percentage load of the machines. The goal of a load sharing system is for all machines to share equally on a percentage of capacity basis. To accomplish this, each machine contains a load controller or kW controller, which provides regulation of the machine’s kW output. The setting for each kW controller is derived from the system load share line voltage.
PAGE 316
In short, when the generator breaker is open, the kW controller is disabled. When the generator breaker is closed and the unit is not paralleled to the utility, the kW controller’s set point is derived from the load share line. When the generator breaker is closed and the machine is paralleled to the utility, the kW controller uses the Base Load Level (%) setting as its set point.
PAGE 317
Step by Step Setup Procedures 1. Wire the DGC-2020, LSM-2020, and any external devices that interact with the DGC-2020 or the LSM-2020. Descriptions of DGC-2020 connections and diagrams showing typical wiring schemes for a DGC-2020 on a generator in various connection schemes (single-phase AB, single-phase AC, Wye, Delta, etc.) are found under Connections.
PAGE 318
b. Configure the load share line voltage range. If load sharing to equipment not produced by Basler Electric, the range of load share voltage utilized by the equipment must be determined. If the voltage range set up in the DGC-2020 does not match that of the devices, correct load sharing will not occur. If all devices are Basler Electric devices, a range of 0 to 10 V is a convenient range.

Figure 7-61. Settings Explorer, Multigen Management, Demand Start/Stop Screen There are two demand start levels and timeouts. This allows the user to set up a lower system power level with a long timeout for normal generator starts, but if the system power level exceeds a higher level for a shorter time (e.g. a machine has an alarm shut down or some other abnormal system power phenomenon occurs) machines can be brought on quickly.

When Disabled, the unit does not participate in sequencing.
PAGE 328
Figure 7-63. Settings Explorer, Multigen Management, Network Configuration These settings are the non-zero sequence IDs of all units that are on the inter-genset communications network. This allows the DGC-2020s to annunciate a pre-alarm if a machine is missing (ID Missing pre-alarm) or if an ID is repeated (ID Repeat prealarm) on the network. These pre-alarms help in diagnosing problems with the intergenset communications network. If these pre-alarms are not desired, set all expected sequence IDs to zero.
PAGE 329
Mains Fail Transfer The DGC-2020 has an internal ATS feature which allows it to monitor the utility, and when the utility fails, opens the mains breaker, starts the generator, then closes the generator breaker to drive the load. When the utility returns and is deemed stable, it will return the load to the utility power. When using the mains fail transfer feature, the DGC-2020 will control the breakers to open and close them to achieve the transition from the utility to the generator.
PAGE 330
iii. Enter the max transfer time. This is the maximum duration allowed for the transfer to be accomplished. If this time is exceeded, a mains fail transfer pre-alarm is annunciated. iv. Configure the Mains Fail Transfer Type setting for open or closed transitions. In open transitions, the generator is not connected directly to the utility at any time.
PAGE 331
ii. Connect the breaker element open and close outputs to the contact outputs that will drive the breaker. iii. Connect the physical input or remote input that has the breaker status (closed if breaker is closed, open when breaker is open) to the Status input of the breaker element. This is the only way to indicate breaker status to the DGC-2020. iv.

close commands simultaneously. The breaker will not change state if it is being commanded to open and close at the same time. Step 7: Verify the breaker is receiving a close command. Breaker close command sources are: • • • • • Step 8: The DGC-2020 itself when the automatic transfer (ATS) feature is enabled. The DGC-2020 itself when the RUN WITH LOAD logic element receives a Start pulse in the programmable logic.
PAGE 341
Step 8: Verify the wiring to the breaker from the DGC-2020. If it seems OK, you can do a manual close and open by modifying the programmable logic. Map some unused outputs to the OPEN and CLOSE outputs from the Gen Breaker Block in the programmable logic. Map a virtual switch to the logic output that would normally be the breaker close output. Map another virtual switch to the logic output that would normally be the breaker close output.
PAGE 342
CLOSE outputs from the Gen Breaker Block in the programmable logic. Map a virtual switch to the logic output that would normally be the breaker close output. Map another virtual switch to the logic output that would normally be the breaker close output. Connect with BESTCOMSPlus®, and exercise the virtual switches using the Control panel located in the Metering Explorer. Never turn open and close on at the same time. This could damage the breaker and/or motor operator.

Synchronizer Active for a Short Time, Then Stops Step 1: Check if a Sync Fail pre-alarm or a Breaker Close Fail pre-alarm is occurring or has occurred. The synchronizer stops acting when such a pre-alarm occurs. Press the Off button or the Reset button on the DGC-2020 front panel to clear these pre-alarms. Step 2: Verify that the Sync Fail Activation delay is sufficiently long to allow the synchronizer to complete the synchronization process.

If the voltage still does not change when varying the bias: • • • Verify that the AVR is equipped and configured to accept bias inputs. Check connections to verify the wiring to the AVR bias is correct. If you have digital voltage regulator, verify it set up and programmed to accept a voltage bias input. Generator Voltage Decreases When AVR Speed Bias is Increased Step 1: Navigate to the SETTINGSMULTIGEN MANAGEMENTAVR OUTPUT screen and set VOLT RESPONSE to DECREASING.

Step 2: Re-attach load share lines to all LSM-2020s that are part of the load sharing system. Run the SINGLE machine with load, and verify that it loads and unloads correctly, and runs at the correct speed. If the machine slows down when the generator breaker is closed, check the load share line voltage. It should be equal, on a normalized basis, to the normalized kW produced by the generator.

bias output range. If the generator breaker is open, voltage trim and kvar control are disabled, so the output from the LSM-2020 will be the midpoint of the range, indicating the voltage regulator should operate at rated voltage. Any relay contacts that are used to switch load share lines, governor analog speed bias signal, or voltage regulator analog voltage bias signals must use a relays intended for low voltage, low current applications to preserve signal integrity.

• WATT DEMAND: This is the normalized requested kW demand on the generator. It is normalized such that 1.0 indicates the full kW capacity of the generator, 0.5 indicates 50% of the generator’s capacity, etc. When the generator breaker is closed, and the kW controller is enabled, the WATT DEMAND indicates what level of power should be generated. In an island load share system, this will correspond to the normalized value read on the load share lines.

• var DEMAND: This is the normalized requested kvar demand on the generator. It is normalized such that 1.0 indicates the full kvar capacity of the generator, 0.5 indicates 50% of the generator’s capacity, etc. When the generator breaker is closed, and the var/PF controller is enabled, the var DEMAND indicates what level of reactive power should be generated. In an island load share system, this will be determined by the droop characteristics set by the Droop Percentage and Voltage Droop Gain parameters.

Mounting LSM-2020’s are contained in a potted plastic case and may be mounted in any convenient position. The construction of a LSM-2020 is durable enough to mount directly on a genset using ¼-inch hardware. Hardware selection should be based on any expected shipping/transportation and operating conditions. The torque applied to the mounting hardware should not exceed 65 in-lb (7.34 N•m). See Figure 9-3 for LSM-2020 overall dimensions. All dimensions are shown in inches with millimeters in parenthesis.
PAGE 359
The RJ-45 socket mates with a standard Ethernet cable and provides local communication between the LSM-2020 and a PC running BESTCOMSPlus® software. This allows for setting of the LSM-2020 and for the DGC-2020 that the module is connected to. LSM-2020 connections are made with an 18-position connector with screw-down compression terminals. This connector plugs into a header on the LSM-2020. The connector and header have a dovetailed edge that ensures proper connector orientation.

APPENDIX B • MODBUS™ COMMUNICATION Introduction General Overview An optional feature of the DGC-2020 performs Modbus™ communications by emulating a subset of the Modicon 984 Programmable Controller. This document describes the Modbus communications protocol employed by the DGC-2020 and how to exchange information with the DGC-2020 over a Modbus network. The DGC-2020 maps all parameters into the Modicon 984 Holding Register address space (4XXXX).

Function Code Field The Function Code field in the Query message defines the action to be taken by the addressed slave. This field is echoed in the Response message, and will be altered by setting the MSB of the field to "1" if the response is an error response. This field is 1 byte. Data Block Field The query Data block contains additional information needed by the slave to perform the requested function. The response Data block contains data collected by the slave for the queried function.
PAGE 415
• • • • Function 03 - Read Holding Registers Function 6 - Preset Single Register, Non-Broadcast & Broadcast Function 08, Subfunction 00 - Diagnostics: Return Query Data Function 16 - Preset Multiple Registers, Non-Broadcast & Broadcast The only Broadcast query supported by the DGC-2020 is the Preset Multiple Registers query. Read Holding Registers Read Holding Registers - General QUERY: This query message requests a register or block of registers to be read.
PAGE 416
Preset Multiple Registers, Non-Broadcast & Broadcast Preset Multiple Registers - General QUERY: This query message requests a register or block of registers to be written. The data block contains the starting address and the quantity of registers to be written, followed by the Data Block byte count and data. A device address is 0 for a broadcast query. A register address of N will write Holding Register N+1.
PAGE 417
• • • Queries writing to Read Only or unsupported registers result in an error response with Exception Code of “Illegal Data Address”. There are several instances of registers that are grouped together (signified as DP or TP) to collectively represent a single numerical (vs. ASCII string) DGC-2020 parameter value. A query to write a subset of such a register group will result in an error response with Exception Code “Illegal Data Address”.
PAGE 418
Long Integer Data Format (INT32) The Modbus long integer data format uses two consecutive holding registers to represent a 32-bit data value. The first register contains the low-order 16 bits and the second register contains the high-order 16 bits. Example: The value 95,800 represented in long integer format is hexadecimal 0x00017638.
PAGE 419
The value of the floating-point number is obtained by multiplying the binary mantissa times two raised to the power of the unbiased exponent. The assumed bit of the binary mantissa has the value of 1.0, with the remaining 23 bits providing a fractional value. Table B-2 shows the floating-point format. Table B-2. Floating Point Format Sign Exponent + 127 Mantissa 1 bit 8 bits 23 bits -37 38 The floating-point format allows for values ranging from approximately 8.43X10 to 3.38X10 .
PAGE 420
Interdependence of Preset Multiple Register Data Preset Multiple Register data is collectively written only after the query has been determined to be legal, which includes a range-check of the entire data block. Therefore, data which must be written prior to other data must use a separate query.

APPENDIX C • TUNING PID SETTINGS Introduction The LSM-2020 (Load Share Module) and DGC-2020 utilize four controllers to accomplish synchronization, load sharing, and speed trim functions. The controllers are a voltage controller, a var/PF controller, a speed controller, and a kW load controller. The voltage and speed controllers are in effect when the DGC-2020 is synchronizing the generator to a bus.
PAGE 524
Table C-1 shows the effects of increasing parameters. Table C-1. Effects of Increasing Parameters Parameter Rise Time Overshoot Setting Time Steady State Error Kp Decrease Increase Small Change Decrease Ki Decrease Increase Increase Eliminate Kd Small Change Decrease Decrease None Tuning Procedures Voltage Controller Tuning Procedure The voltage controller is tuned prior to the speed controller.
PAGE 525
Tuning of KD can be achieved through the following steps. First set TD=0 to eliminate filtering. Raise speed KD and check for stability. Each time KD is raised, disturb the system by changing the voltage on the bus input of the DGC-2020 so that the DGC-2020 will try to follow it. Verify that the DGC-2020 controls the voltage to go to the new value in a stable manner. Raise KD until the system is unstable, and then lower it to half the value where instability if first attained.
PAGE 526
Speed Controller Tuning Procedure The speed controller is tuned prior to the kW load controller. Set Load Control to enabled, and speed trim to enabled. Set all Kp, Ki, and Kd gains in both speed controller and kW load controller to 0. Set the Kg values to 0.1. Start the generator and close the breaker onto some load. KP - Proportional Gain Set an initial value of 1 for KP. Each time KP is set, manually displace the governor lever if possible and see that control is regained in a stable manner.
PAGE 527
If it is not possible to obtain stable kW operation, it may be necessary to reduce the control gains in the governor that has its analog bias input driven by the LSM-2020. KI - Integral Gain Set the initial value of KI to be a tenth of the value set for KP. Each time KI is set, parallel a second generator with the unit being tuned, and check for stable load sharing then open the generator breaker on the second generator and check that the unit being tuned is still stable.

APPENDIX E • EXHAUST TREATMENT Diesel Particulate Filter (DPF) In order to meet Tier 4 emission requirements, some engine manufacturers are applying Diesel Particulate Filters (DPF) to the exhaust system of the engine. A Diesel Particulate Filter traps particulate matter contained in diesel exhaust and prevents it from distributing into the air. The particulate matter is later burned off during a regeneration process.
PAGE 540
DPF Status and Pre-Alarms The DGC-2020 receives DPF status information which is broadcast from the engine ECU in various Parameter Group Numbers (PGN) and Suspect Parameter Numbers (SPN). The DGC-2020 displays this information on the front panel, and in BESTCOMSPlus, via DPF related pre-alarms. The J1939 parameters and the resulting DGC-2020 pre-alarms are summarized in the following paragraphs.
PAGE 541
Exhaust After Treatment Systems (EATS) In order to meet Tier 4 emission requirements, some engine manufacturers are adding Exhaust After Treatment Systems (EATS) which treat the engine exhaust within the exhaust system to reduce particulate matter and harmful contaminants prior to releasing the exhaust into the atmosphere. One such system uses urea-based Diesel Exhaust Fluid (DEF) catalyst which is combined with the exhaust gasses in the EATS to bring the emissions to acceptable levels.
