[. . . ] LCD DISPLAY Vab 600 Vbc 600 Vca 600 PM056 Rev 6 05/10/15 39 Thomson Technology MEC 2 MICROPROCESSOR ENGINE/GENERATOR CONTROLLER Displays generator voltage as follows: 3-phase system: LINE TO LINE VOLTAGE--Phases A to B 1-phase system: LINE TO LINE VOLTAGE--Phases A to B Displays generator voltage as follows: 3-phase system: LINE TO LINE VOLTAGE--Phases B to C 1-phase system: LINE TO NEUTRAL VOLTAGE--Phases A-N Displays generator voltage as follows: 3-phase system: LINE TO LINE VOLTAGE--Phases C-A 1-phase system: LINE TO NEUTRAL VOLTAGE--Phases B-N 8. 2. 4. 4. GENERATOR PHASE/NEUTRAL VOLTAGE DISPLAY (LINE TO NEUTRAL) The generator phase/neutral display allows the operator to view the generator line to neutral voltage for all 3 phases of the system. Note: The generators neutral must be connected to MEC 2 terminal TB1-VN and the "neutral connected" prompt in the main program menu must be selected as "Yes". LCD DISPLAY Van 347 Vbn 347 Vcn 347 Displays generator voltage Phase A to Neutral. Displays generator voltage Phase B to Neutral. Displays generator voltage Phase C to Neutral. 8. 2. 4. 5. GENERATOR PHASE CURRENT DISPLAY The generator phase current screen allows the operator to view the generator load current on all 3 phases (or single phase system as selected). LCD DISPLAY Amps a 408 b 451 c 415 PM056 Rev 6 05/10/15 40 Thomson Technology MEC 2 MICROPROCESSOR ENGINE/GENERATOR CONTROLLER Displays generator load current as follows: 3-phase system: PHASE A CURRENT 1-phase system: PHASE A CURRENT Displays generator load current as follows: 3-phase system: PHASE B CURRENT 1-phase system: PHASE B CURRENT Displays generator load current as follows: 3-phase system: PHASE C CURRENT 1-phase system: not applicable 8. 2. 4. 6. GENERATOR FREQUENCY/HOURMETER DISPLAY The generator frequency and operating hours are displayed simultaneously on this screen. LCD DISPLAY FREQ HOURS 60. 1Hz 56783 Hrs Displays generator frequency in hertz (HZ). The frequency is displayed with a resolution of 1/10 of a hertz. ENGINE PARAMETER DISPLAY Two engine operating parameter screens are provided as described below. 8. 2. 5. 1. BATTERY VOLTAGE/ENGINE SPEED (tachometer) The battery voltage and engine speed are displayed simultaneously on this screen. LCD DISPLAY BATTERY SPEED 27. 0Vdc 1800rpm PM056 Rev 6 05/10/15 41 Thomson Technology MEC 2 MICROPROCESSOR ENGINE/GENERATOR CONTROLLER Displays battery voltage in DC volts. The voltage is displayed with a resolution of 1/10 of a volt. Displays engine speed in revolutions per minute (RPM). 8. 2. 5. 2. ENGINE TEMPERATURE/OIL PRESSURE The engines operating temperature and oil pressure are displayed simultaneously on this screen. LCD DISPLAY ENG TEMP OIL PRESS 57 Deg C 200 KPA Displays engine temperature in either degrees Celsius or Fahrenheit (as selected). Displays engine oil pressure in either pounds per square inch (PSI) or in Kilopascals (KPA) (as selected). 8. 2. 6. PROGRAM MENU The programming menu is used to access the MEC 2 programmable functions such as time delays, analog fault settings, digital fault settings and calibration. Access to the programming sub-menus may only be obtained with a security password number. The sub menus are organized as follows: PROGRAMMING MENU LCD DISPLAY NO YES PASSWORD PROGRAM MENU?NO Displays two messages that may be toggled between YES and NO by pressing the INCREMENT pushbutton. Their functions are described as follows: NO YES Programming sub-menus are disabled when NO is displayed. [. . . ] Failure to do so may result in serious personal injury or death due to electrical shock. Service procedures must be undertaken by qualified personnel only!SYMPTOM power applied CORRECTIVE ACTION circuits connected to the controller. Note: The MEC 2 contains an electronic fuse that triggers upon an over load condition and does not reset until the supply voltage is removed, and over load condition is corrected. LCD Display is not operational - Check that the controller's microprocessor is running by observing a red flashing "watchdog" LED on the rear of the PCB. [. . . ]
