FUNCTIONS

Genset Protection:

Generator (All Levels): Undervoltage (27) Overvoltage (59) ANSI Codes Reverse Power (32) Overfrequency (81O)

Loss of Excitation (40Q) Underfrequency (81U)

Generator (Level 2 / 3 only): Phase Imbalance (47) Generator Overcurrent (51) ANSI Codes

All Generator Protection features are programmable as alarms, pre-alarms, status or not used.

All alarms and pre-alarms can be enabled or disabled via the BESTCOMSPlus PC software or the front panel. Additional custom alarms and pre-alarms are available upon request.

Genset Metering:

♦ Generator parameters consist of 8 standard parameters including, but not limited to voltage, current, Hz, realpower (watts), apparent power (VA), and power factor. The view can be programmed to display up to 20parameters using the scrolling and time delay feature.

♦ Engine parameters include oil pressure, coolant temperature, RPM, battery voltage, fuel level, engine runtime,and various J1939 supported parameters.

Engine Control:

♦ Cranking Control: Cycle or Continuous (Quantity and Duration Fully Programmable)♦ Engine Cooldown: Smart Cooldown function saves fuel and engine life.♦ Successful Start Counter: Counts and records successful engine starts♦ Timers including, but not limited to:

• Engine Cooldown Timer• Engine Maintenance Timer• Pre-Alarm Time Delays for Weak/Low Battery Voltage• Alarm Time Delay for Overspeed• Alarm Time Delay for Sender Failure• Arming Time Delays after Crank Disconnect:

- Low Oil Pressure - High Coolant Temperature

Pre-Alarms (Warnings) Low Oil Pressure High Coolant Temperature Low Coolant Temperature Battery Overvoltage Weak Battery Battery Charger Failure Engine Sender Unit Failure Engine kW Overload (3 levels) Maintenance Interval Timer Low Coolant Level Low Fuel Level Fuel Leak Detect High Fuel Level

Engine: Alarms (Shutdowns) Low Oil Pressure High Coolant Temperature Low Coolant Level Low Fuel Level Overspeed Overcrank Engine Sender Unit Failure Fuel Leak/Fuel Sender Failure Emergency Stop Battery Charger Failure Critical Low Fuel Shutdown


FUNCTIONS Event Recording The DGC-2020 has an event recorder that provides a record of alarms, pre-alarms, engine starts, engine runtime loaded, engine runtime unloaded, last run date, and many other events that are all date and time stamped to help the user determine the cause and effect of issues related to the generator set. Contains 30 event records each retaining up to 99 occurrences in memory. Time, date and engine hour detail is available for the most current 30 occurrences within each event record.

Transfer Switch Control (Mains Failure) - Level 3 only The DGC-2020 monitors utility (mains) and determines if it is providing voltage that is suitable for the loads. If the utility (mains) goes beyond predetermined levels, the generator is started and the utility (mains) is disconnected from the load and the generator is connected. When the utility (mains) returns to acceptable levels for a sufficient time, the generator is disconnected and the utility (mains) is reconnected to the load. It also includes appropriate adjustable timers or time delays for establishing stable utility (mains) operation. Utility breakers must be electronically operated.

RS-485 Communications When utilized, the user can send and receive information from the DGC-2020 via the RS-485 communications port and Modbus-RTU protocol. This feature allows the DGC-2020 controlled genset to be fully integrated into the building management system. Please see the Instruction Manual for the Modbus register list.

Programmable Logic The DGC-2020 offers a very powerful, yet easy to use, programmable logic scheme for custom programming of the various inputs, outputs, alarms, and pre-alarms. It allows these elements to be integrated into a complete logic scheme so that the user can meet even the most complex specification. The Programmable Logic control includes the selection of logic gates and timers with drag-and-drop technology to make it fast and simple.

Remote Display Panel Annunciation The DGC-2020 can communicate to a remote display panel, Model RDP-110. This requires only two wires to annunciate all of the alarms and pre-alarms required by NFPA-110 Level I and II. External power is required.

Modem - Level 2 and 3 only A 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.

J1939 Communications J1939 CANBUS communications allows the DGC-2020 to communicate to the engine's ECU (Engine Control Unit) to gather critical engine information like oil pressure, engine coolant temperature, RPM, battery voltage, and many more. By utilizing the ECU, adding analog engine senders is no longer required. This can save substantial money for the installer. It also eliminates any errors or discrepancies between the ECU data and the data displayed on the DGC-2020 that may be present due to analog sender inaccuracies or incompatibility. A total of 47 engine parameters can be obtained via the ECU. You also can derive the added benefit of having access to the ECU's diagnostic troubleshooting codes, or DTCs. The DTCs provide information about the engine's operating conditions and communicates these via J1939, to the DGC, thus eliminating the need for hand-held service tools to diagnose simple engine issues. With the optional modem, the DTCs can be accessed remotely, and valuable service time can be saved by remote diagnostics and taking the right parts to fix the problem the first time.

ADDITIONAL SPECIFICATIONS

The DGC-2020 has been designed to provide maximum functionality at a minimum price. You only buy what you need. Below are options selected to help maximize the value provided by the DGC-2020.

Battery Backup for Real Time Clock - All Levels A ten-year (typical life) lithium battery is used to provide long-term maintenance of the real time clock setting. This battery is serviceable by removing the rear cover. The settings, programming, and event records are saved in nonvolatile memory and do not require battery backup.

Internal Dial-In / Dial-Out Modem - Levels 2 and 3 The DGC-2020 can provide long distance communications by including an internal modem. There are two modems available, one for U.S. and one for European telephone systems. When a modem is selected, the user can access the DGC-2020 from virtually anywhere via a telephone line. The user can control and monitor the genset as if standing right next to it. The DGC-2020 can also dial out for pre-programmed circumstances to alert the user of selected conditions.

Additional Generator Protection - Levels 2 and 3 In addition to the standard generator protection (27, 32, 40Q, 59, 81O, 81U), the DGC-2020 also can be equipped with a more sophisticated generator protection system. This option provides an overcurrent element (51) with 17 selectable time current characteristic curves and a voltage phase balance protection function (47).

Breaker Management - Level 3 only The DGC-2020 is capable of controlling the generator breaker and the mains breaker. The status of the breakers is determined by using BESTLogicPlus Programmable Logic to setup the GENBRK and MAINSBRK logic blocks. These logic blocks have outputs that can be configured to energize an output contact and control a breaker as well as inputs for breaker control and status. The DGC-2020 will attempt to close a breaker only after verifying that it can be closed. If the breaker cannot be closed, the close request will be ignored. Only one breaker can be closed at a time. Synchronization is required before closing the breaker to a live bus. Closure to a dead bus can be performed after meeting dead bus threshold and timing requirements set by the user.

Auto-Synchronizer - Level 3 only When the DGC-2020 is configured with this option, the user can select between 2 types of autosynchronizers, phase lock or anticipatory style. In both methods, the DGC-2020 adjusts generator frequency and voltage to match that of the bus (mains) via contact outputs, then connects the generator to the bus by closing the connecting breaker. When the control mode is set to Power Factor (PF) or kVar, the setpoint can be derived either from a user setting or from an analog input.

Multigen Management - Level 3 only Enabling sequencing on a networked group of load share units allows these units to manage load by starting and stopping appropriate units based on a factor of load demand and available capacity. The mode of operation is used to determine the order in which each generator in a group will contribute to the systems power production upon a demand start/stop request.

Modes of operation include: Staggered service time Balanced service time Largest size first Smallest size first Smallest unit ID

Communications via CANbus: The CEM-2020 communicates to the DGC-2020 via SAE J1939 CANbuscommunications and allows the user to program the functionality of these inputs and outputs in the BESTCOMSPlus software.

The user can add labels for the inputs and outputs that appear in BESTCOMSPlus, show up on the front panel, and in programmable logic. All the functionality can be assigned to these inputs and outputs as if they were an integrated part of the DGC-2020. The CEM-2020 module has all of the environmental ratings, like the DGC-2020, including a model for UL Class1 Div2 applications. The CEM-2020 terminals accept a maximum wire size of 12 AWG while the chassis ground requires 12 AWG wire. Flexibility is one of the benefits of the DGC-2020, and this add-on module enhances that benefit even further. The CEM-2020 is available for all levels, but is only functional for paralleling with Level 3.
