Diesel Generator Controllers MSU4.2 ENKO Electronic Control Systems - IZMIR / TURKIYE Automatic / Manual Start Unit for Gen-Sets MSU4.2 control panel offers exten- MSU4.2 Automatic/Manual Start control unit is designed for single Gen- sive start and control functions for erators, where mains line monitoring is not required. The unit has all the necessary functions to start the Diesel engine safely and control Gen-Sets, where mains control is not required. engine parameters, while monitoring the alternator voltage and load current. All voltage and current values are monitored in True RMS values and displayed on the panel. There is no need for additional panel meters. Load power is also measured and displayed. User can operate functions on these values. The unit also provides all the necessary protection and monitoring of the engine values. The engine temperature and oil pressure is also displayed on analog bar graph displays, hence eliminating the use of additional gauges on the panel. Pre-heat function can be used for secure starting under very cold whether conditions. The DC battery voltage is measured and displayed. Alarm function can also be initiated, depending on the battery supply voltage. All alarms are logged and the last 10 alarms can be seen in the past log records. Provides flexible The unit can be remotely controlled by a remote start input function, Main features: Automatic and Manual control of Diesel Generator and Alternator parameters, Remote start input allows easy interface to other control systems, 3 phase True RMS measurement and monitoring of load voltage and current values, Manual and automatic control of GCB, Engine hours working time memory and service log, Programmable auxiliary inputs and outputs, DC Battery voltage level measurement, hence allowing gen-set to be controlled by other systems. Engine working hours are recorded in the system memory. Load power is also measured and monitored and special functions can be activated on these measured values. User can also program periodic service time for Digital calibration for analog input variables from menu, the engine. The unit has configurable i/o ports which can be programmed according to user application. Analog measuring input calibra- Internal charge alternator excitation control , tion can be made from the menu. There is no need to open the unit enclosure. Five digital displays allow most critical values to be displayed simultaneously, which allows easy monitoring from the front panel. Alarm logging for the last 10 alarm signals, OFFERS ECONOMICAL SOLUTIONS FOR SINGLE GENSET APPLICATIONS SIMULTANEOUS MONITORING OF 5 DIGITAL VALUES ANALOG MONITORING (BAR-GRAPH DISPLAY) FOR ENGINE TEMPERATURE AND OIL PRESSURE Additional features: FULLY CONFIGURABLE AUXILIARY INPUTS AND OUTPUTS MEASUREMENT OF LOAD POWER (KW and KVA) ANALOG ENGINE TEMPERATURE AND OIL PRESSURE BAR-GRAPH DISPLAY DC power supply: Operating temperature: Relative humidity: Frequency measurement: Current measurement: Shunt type measuring, x/5A current transformer should be used Charge alternator excitation current: Measurement accuracy: Phase voltages: ±2% of scale, Phase currents: ±2% of scale, Frequency: ±0.1Hz 4 configurable inputs 3 configurable outputs (relay contact outputs) Relay contact ratings: Protection class: IP52 (front panel protection) FULL ENGINE CONTROL ON-OFF FRONT PANEL CONTROL BUTTON FOR GCB CONTACTOR MULTI DIGITAL DISPLAY ARCHITECTURE FOR EASY MONITORING PRE-HEAT CONTROL ON AUTOMATIC AND MANUAL START SEQUENCE Technical specifications: INPUT VOLTAGE MEASUREMENT RANGE UP TO 300Vac (Phase to Neutral) IP52 PROTECTION CLASS OVER THE FRONT PANEL WIDE TEMPERATURE RANGE
