5 Control System function list Control System PLC-7420 PLC-7420 is an advanced control module based on micro-processor, containing all necessary functions for protection of the genset and the breaker control. It can monitor the mains supply, breaker control. and automatically start the engine when the mains is abnormal. Accurately measure various operational parameters and display all values and alarms information on the LCD. In addition, the control module can automaticallyshut down the engine and indicate the engine failure. FEATURES Microprocessor control, with high stability and credibility Monitoring and measuring operational parameters of the mains supply and genset Indicating operation status, fault conditions, all parameters and alarms Multiple protections; multiple parameters display, like pressure, temp. etc. Manual, automatic and remote work mode selectable Real time clock for time and date display, overall runtime display, 250 log entries Overall power output display Integral speed/frequency detecting, telling status of start, rated operation, overspeed etc. Communication with PC via RS485 OR RS232 interface, using MODBUS protocol General accessory Operator Interface Measurement and Instrumentation Shutdown Protection and Indication Threshold Warning&Indication Paralleling Capability MODEL AVR Electronic Governing Glow plug control Cycle Cranking MODBUS Networking Fault History manual start/stop Auto/remote start Regular Test Auto operation LED Manual operation LED Common Shutdown LED Common warning LED Fail to start LED Emergency stop(local) Alphanumeric screen Remote start input active LED Alarm reset Oil pressure Water Temperture Engine Speed Engine Engine Altamator Altamator Mains Expression Hours Run Number of Starts Battery Voltage Coolant Temperature 3PhaseL-L Voltage&Frequency 3phase Current Frequency kwh Apparent Power Active Power and Reactive Power Power Factor Per PhasekW, kwr Per Phase kva Phase Voltage Output Power Grid Line Voltage Grid Phase Voltage Grid Frequency Low Fuel Level High Fuel Level Low Oil Pressure High Water Temperature Failure to Stop Failure to Start Controlable start circles/times Overspeed Under&Over Voltage Under&Over Frequency Overcurrent Earth Leakage Reverse Power Reverse kwr Low Oil Pressure Low Water Temperature High Water Temperature Low Water Level Low/High Battery Voltage Failure to Charge Overcurrent Overload Genset Under/Over Voltage Genset Under/Over Frequency under/over Speed High Engine Temperature Earth Leakage Synchroscope(Independent Bus) Active and Reactive Power Control Synchroscope(Shared Bus) Synchronization Dector Peak Lopping PLC-8610 PLC-7420 Power Transfer Function Environment Automatic Transfer Hard Closed Transition Soft Closed Transtion Gen/Mains Breaker Gen/Mains Breaker Status Protection Speed/Voltage Control Power Indication Fuel&solenoid Valve Control Startor Control Preheating Mains Transfer Switch (Standard) Mains Transfer Switch (Emergency) Operating Temperature ( ) Ambient Temperature ( ) Humidity 80% Monitoring Function Grid Over/Under Voltage Control Grid Over/Under Frequency Control Remote Start Output(Load/No-load) Optional Relay Output Remote Telecom Control with All Functions Engine Instrument Monitoring Altemator Output Instrument Monitoring Connection Point with All-around Setting For 6 Users 3 Users Input Connection Point LCD Light Control of Low Light Operation Environment Safe PIN Code RS232/485 Interface Language Selection Multi-Language Function Standard Optional Impossible

6 Control System Digital, intelligent control system allows easier operation. PLC-8610 (Optional) FEATURES Microprocessor control, with high stability and credibility Monitoring and measuring operational parameters of the genset Indicating operation status, fault conditions, all parameters and alarms Multiple protections; multiple parameters display, like pressure, temp. etc. Manual, automatic and remote work mode selectable RS232 & RS485 can be used at the same time Real time clock for time and date display, overall runtime display, 250 log entries PLC-8610 is a microprocessor based control unit containing all necessary functions for protection of the genset and the breaker control. Furthermore, it contains all necessary three-phase measuring circuits and presents all values and alarms on the LCD display. The module has the function of load sharing which enables the module to share the active load (kw) equally when operating in parallel with other gensets. The load sharing is performed so each genset takes a portion of the load that is calculated in percent according to the nominal power.
