SECTION 3  FUNCTIONAL DESCRIPTION INTRODUCTION This section describes how the DGC-2020 functions. A detailed description of each function block is provided in the paragraphs under the heading of DGC-2020 Function Blocks. DGC-2020 operating and metering features are described in Section 4, BESTCOMSPlus Software. DGC-2020 FUNCTION BLOCKS To ease understanding, DGC-2020 functions are illustrated in the block diagram of Figure 3-1. The following paragraphs describe each function in detail.
PAGE 50
Zero Crossing Detection The zero crossing of A-phase to B-phase or A-phase to C-phase (user-selectable) line voltage is detected and used to calculate the generator frequency. The zero crossing of A-phase to B-phase bus voltage is used to calculate the bus frequency. Analog-to-Digital Converter 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 analog-to-digital converter.
PAGE 51
Coolant temperature sender connections are made at terminals 10 and 11 (sender common). Fuel Level A current is provided to the fuel level sender. The developed voltage is measured and scaled for use by the internal circuitry. An open circuit or short circuit across the fuel level sender terminals will cause the DGC-2020 to indicate a failed sender. Fuel level senders that are compatible with the DGC-2020 include Isspro model R8925. Other senders may be used.
PAGE 52
Connections for the programmable inputs are provided at terminals 15 (Input 16) through 30 (Input 1). The negative side of the battery voltage (terminal 2) serves as the return connection for the programmable inputs. Front Panel HMI The front panel HMI provides a convenient interface for viewing system parameters and for controlling the DGC-2020/generator set. Front panel HMI components include an LCD (liquid crystal display), LED (light emitting diodes) indicators, and pushbuttons.
PAGE 53
USB The rear-panel, mini-B USB socket enables local communication with a PC running BESTCOMSPlus software. The DGC-2020 is connected to a PC using a standard USB cable. BESTCOMSPlus is a Windows® based communication software package that is supplied with the DGC-2020. A detailed description of BESTCOMSPlus is provided in Section 4, BESTCOMSPlus Software.

input is open (emergency stop condition), the Pre-Start, Crank, and Fuel outputs open. When the Emergency Stop input is closed, all output contacts operate normally. DGC-2020 output contacts include Pre-Start, Crank, Fuel, and up to 12 standard programmable outputs. Additional output contacts can be accommodated with a CEM-2020 (Contact Expansion Module). Pre-Start 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.
PAGE 58
Generator Exerciser The unit will start at the designated time and will run for the specified duration. The breaker will be closed if “Run with Load” is checked in the generator exerciser settings. This mode is independent of the other self-starting modes. 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.
PAGE 59
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. OFF or AUTO Mode (Not Running) If operating in the OFF mode or AUTO and not running, the generator breaker cannot be closed because the generator will not be stable.
PAGE 60
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.  The DGC-2020 itself when started from the Exercise Timer and the Run with Load box is checked in the Generator Exerciser Settings.

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).
PAGE 278
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. An error response will substitute an Exception Response Code for the Data Block. The length of this field varies with each query.
PAGE 279
 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. The data block contains the starting register address and the quantity of registers to be read. A register address of N will read Holding Register N+1.
PAGE 280
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 281
 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”.  A query to write an unallowed value (out of range) to a register results in an error response with Exception Code of “Illegal Data Value”.
PAGE 282
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 283
The second register contains the low-order 16 bits of double precision data, and is the actual data value modulus 10,000. Triple Precision Data Format (TP) The Modbus Triple Precision data format (TP) uses 3 consecutive registers to represent a data value. The first register contains the high-order 16 bits of triple precision data, and is the actual data value / 100,000,000.

APPENDIX C  TUNING PID SETTINGS INTRODUCTION The LSM-2020 (Load Share Module) and DGC-2020 utilize three controllers to accomplish synchronization, load sharing, and speed trim functions. The controllers are a speed controller, a voltage controller, and a kW load controller. The voltage and speed controller are in effect when the DGC-2020 is synchronizing the generator to a bus. When synchronizing, these controllers adjust the speed and voltage output of the generator to match that of the bus.
PAGE 332
TUNING PROCEDURES Voltage Controller Tuning Procedure The voltage controller is tuned prior to the speed controller. Set all gains in voltage controller, speed controller, and KW load controller to 0. Start the generator and close the breaker onto some load. The voltage controller is only active during synchronization when the DGC-2020 is trying to close the generator breaker. In order to tune it, a variable AC voltage source must be connected across the bus input of the DGC-2020.
PAGE 333
Var/PF Controller Tuning Procedure Once desired voltage controller performance is obtained, the Var/PF controller can be tuned. Set all gains in the Var/PF controller to 0, enable the Var /PF controller, and set the control mode to Var control. The generator must be paralleled to the utility (as indicated by the Parallel to Mains element in logic) in any of the tuning steps where the system is being tested for stable operation. KP - Proportional Gain Set an initial value of KP = 1 in the Var/PF Controller.
PAGE 334
and the speed it is trying to reach. The important thing is that the generator’s output behaves in a stable manner. If the system is unstable, lower KP and repeat. Repeat this procedure, raising KP until the system is unstable, and then lower it to half the value where instability is first attained. If it is not possible to obtain stable speed operation, it may be necessary to reduce the control gains in the governor that has its analog bias input driven by the LSM-2020.
PAGE 335
KD - Derivative Gain If the performance with KP and KI alone is satisfactory, you may stop here. Otherwise, KD, the derivative controller gain, can be used in conjunction with TD, the noise filter constant, to reduce overshoot obtained with the PI control. Setting KD and TD is an iterative process. Start with small values of KD such as 0.1 or half the KI value, whichever is less.
