gac’s Generators Set Controller Series (GNS2000 Series) is a family of highly-fl exible generator set controllers for standalone applications. The GNS2000 Series, designed for both electronically and mechanically controlled engines, is ruggedly constructed with simple-to-use microprocessor technology. gac’s new controller series provides superior generator set control, protection, and metering all at a reasonable cost.

Programming the GNS2000 Series is easily accomplished by utilizing either the front panel navigation keys and the large LCD display or with gac’s enhanced smartVu™ confi guration software. The controller senses engine parameters directly via 4 analog inputs and it can communicate with the engine’s electronic control unit via J1939 CANbus protocol. The programmable inputs and outputs are engineered to allow the user to easily customize the operation as desired.

The GNS2000 Series has been designed to provide maximum functionality at a minimum price. Standard features include: 9 programmable inputs and 9 programmable outputs; 4 analog inputs that support a wide range of senders; 2 Form A and 2 Form C relays; robust electronic protection; fi xed, variable and binary voltage detection schemes; remote control and monitoring; one built in RS-232/485 port and one RS232 (GNS2004B GNS2004BE) with expansion for fi eld service laptop support; Modbus and J1939 CANbus interface; multiple, memory-resident languages: and an industrial temperature range operation of -40° to +85°C. To reduce costs, gac offers within the GNS2000 Series a no display, black-box version and an optional operating temperature range (-20° to +85°C) version.

Added features are easily incorporated in the unit without adding on high additional costs. Optional features include: internal and external modem; analog user interface; remote displays, relays and control modules; and expandable I/O capabilities via J1939 CANbus.

As with all gac products, the GNS2000 Series can be easily and cost effectively adapted to provide customized solutions for OEMs.

Operating MOdesThe GNS2000 Series can be operated in Manual, Auto or Off modes, and has a full suite of engine and generator protections. When in Manual mode, the GNS will start and stop the engine based on user inputs. In Auto mode, the GNS will start and stop the engine when the remote start/stop input is received. Voltage detection is possible via one of three methods, auto-detection, fixed voltage operation, or assign binary inputs to indicate the desired voltage.

alarMs, Warnings, and prOtectiOnsThe GNS alarms and warnings alert the user while protecting the generator and engine. Virtually all protections can be individually enabled or disabled. Shutdown conditions include low oil pressure, low fuel level, high coolant temperature, under/over speed, under/over voltage, over current, over frequency, sensor failures, over crank, and generator voltage unbalanced.

EnginE COntrOl

• Cranking control provides pre-lube, up to 4 pre-start stages, adjustable number of crank attempts, duration, pause delay and crank disconnect. Also provided is an engine start counter.

• Enginetimersincludeservice,pre-start,crank,idle,cool down, and after cool.

• Adjustable protection thresholds and delays forspeed, oil pressure, coolant temperature, and fuel level.

• Integrationw/J1939ECUs.

MEtEring

• Meteredgeneratorparametersincludelinevoltage,line to line voltage, current, frequency, reactive power, power factor and actual power.

• Metered engine parameters include RPM, oilpressure, coolant temperature, battery voltage, fuel level, service hours, run hours, and number of starts. RPM, oil pressure, and coolant temperature can be acquired via J1939.

inputsThe GNS is equipped with dedicated inputs for generator voltage, generator current, and a speed sensor. The unit is also equipped with 4 configurable analog inputs and 9 configurable binary inputs. The analog inputs allow a wide range of sensors including voltage, current, and resistive senders. Though easily reconfigured, three of the analog inputs are configured for Fuel level, Engine temperature, and Oil Pressure. The GNS2000 Series can use J1939 messages for oil pressure, engine speed, and coolant temperature in combination with the analog inputs for control and protection operations, thereby, freeing up analog inputs for other sensors.

OutputsThe GNS2000 Series is equipped with 5 discrete binary outputs and four relays. The discrete outputs can sink up to 500mA of current to battery ground and support up to 32VDC. The GNS2000 Series has four relays, two Form C and two Form A. Though reconfigurable, one Form C relay is configured to control the fuel solenoid, the other is configured to control the starter. By adding a jumper (located on the back of the GNS), the fuel relay can be configured to be directly controlled by the emergency stop input – when the emergency stop input is activated, power to the fuel solenoid is removed, thereby depriving the engine of fuel.

All GNS2000 Series analog inputs, binary inputs, relays and binary outputs assignments can be configured by the user.

RS232/485, SAE J1939, EthERnEt, ModbuSThe standard GNS is equipped with a SAE J1939 port and one serial port. The serial port can be configured for RS232 or RS485 operation. The RS232 can connect the GNS to an external modem, external I/O, remote display, Ethernet converter or PC using the industrystandardMODBUSprotocol. A factory installedmodemcan be ordered or an external modem can be added to provide dial in and dial out remote monitoring**. For SMS functions, an external cell modem can be added. Note: the GNS2004B and GNS2004BE is a stand-alone controller equipped with an additional RS232 ports and can be operated without a display.

reMOte annunciatOr, Output relays, & prOgraMMable lOgic

The optional gac Remote Annuciator (RA20) and Contact Relay Module (CRM20) provide external programmable logic and annunciation for the GNS2000 Series. The RA20 is equipped with 20 LEDs and can be panel mounted. The CRM20 is similar to the RA20 with the inclusion 20 Form C relays. Both of these devices have 30 blocks for logic programming and can source data via Modbus over two RS-232/485 ports and J1939 over CAN bus.

gns2000 displayThe GNS2000 Series is equipped with a 64 x 128 graphical display, status LEDs, buttons (with the exception of GNS2004B and GNS2004BE). Depending on the configuration the display can support mulitple languages simultaneously. The user can switch between the languages on the fly.

smartVuThe GNS2000 Series is configured using the accompanying smartVu PC configuration, control and monitoring tool. This program allows the user to set and modify security, operating set points, assign I/O, establish warning and alarm thresholds, and control overall system behavior. Once configured, the settings can be saved to a file for easy replication. While connected to a GNS, smartVu can be used to monitor generator set performance. (see Figure 1.)

Within smartVu, the layout of the display is highly customizable. The user chooses which meters are to be displayed, and the location on the screen. The screen configuration can be stored for later use.

smartVu is capable of simultaneously communicating with multiple GNS controls, and the layout of the screen is customizable.
