MEC 20 DISPLAY MENUS The MEC 20 contains a Liquid Crystal Display (LCD) which is visible through the front lexan faceplate viewing window. The LCD has pre-programmed display screens and menus that may be selected by pressing the ENTER or EXIT push-buttons in succession until the desired screen or menu is displayed. The display screen types and order in which they are programmed are as follows: PM047 Rev 13 05/03/30 41 Thomson Technology MEC 20 MICROPROCESSOR ENGINE/GENERATOR CONTROLLER OPERATING STATUS TIMER COUNTDOWN FAULT DISPLAY GENERATOR METERING (Average) GENERATOR PHASE VOLTAGES GENERATOR LINE TO NEUTRAL VOLTAGES GENERATOR PHASE CURRENTS GENERATOR KVA GENERATOR FREQUENCY/HOURMETER BATTERY VOLTAGE/ENGINE SPEED (TACH) ENGINE TEMPERATURE/OIL PRESSURE PROGRAM MENU FAULT DISPLAY (Multiple Faults) 9. 2. 1. OPERATING STATUS MENU The operating status menu provides the operator with detailed information as to the status of the engine-generator set. NOTE: The operating status screen may be momentarily replaced with a time delay countdown screen when a start or stop sequence is initiated. The display will automatically return to the previous menu following expiry of the timing sequence. PM047 Rev 13 05/03/30 42 Thomson Technology MEC 20 MICROPROCESSOR ENGINE/GENERATOR CONTROLLER The operating status sub-menus are organized as follows: OPERATING STATUS UNIT READY SWITCH IN OFF UNIT RUNNING UNIT SHUTDOWN UNIT ALARM 9. 2. 1. 1. UNIT READY This indicates that the controller is in "Auto" position and there are no active shutdowns or alarms. 9. 2. 1. 2. SWITCH IN OFF This indicates that the controller has been selected to the "off" position from the front panel keypad push-button. 9. 2. 1. 3. UNIT RUNNING This indicates that the engine is running and all conditions are normal. 9. 2. 1. 4. UNIT SHUTDOWN This indicates that a shutdown fault is active. The specific fault condition will be automatically displayed. 9. 2. 1. 5. UNIT ALARM This indicates that one or more alarm fault circuits are active The display will automatically scroll through all active faults at a rate of every two seconds. 9. 2. 2. FAULT DISPLAY MENU The fault display menu is automatically displayed when either an alarm or shutdown circuit is activated. The specific alarm or shutdown fault label will be displayed and if multiple alarm conditions are present, the display will automatically scroll through all active faults. 9. 2. 3. TIMER COUNTDOWN MENUS Timer countdown menus are automatically displayed when a specific time delay function occurs during a control sequence. When a time delay begins, the LCD display will indicate the time delay function name (i. e. ENGINE START DELAY) PM047 Rev 13 05/03/30 43 Thomson Technology MEC 20 MICROPROCESSOR ENGINE/GENERATOR CONTROLLER and the current time remaining in the countdown sequence. When the timing function has expired, the LCD display will automatically change to either the next timing sequence countdown display or return to the original system status menu. LCD DISPLAY ENGINE START DELAY 45 SEC Displays specific time delay function currently in operation Displays current time in seconds or minutes that are left in the specific timing sequence. NOTE: During a timer countdown sequence, a different display screen may be selected by pressing the "ENTER" push-button. The following timer countdown screens are provided: ENG START DELAY CRANK PERIOD REST PERIOD STARTER RE-ENGAGE DELAY BYPASS DELAY COOLDOWN DELAY WARMUP DELAY* RETURN DELAY* NEUTRAL DELAY* programmed. XX SEC. ** Countdown screens only appear if Utility Gen Ready to Load outputs are 9. 2. 4. GENERATOR AC METERING Four generator AC metering screens are provided as described below. 9. 2. 4. 1. AVERAGE DISPLAY VOLTAGE/CURRENT & FREQUENCY The generator average voltage/current & frequency metering screen allows the operator to simultaneously view all the listed parameters. PM047 Rev 13 05/03/30 44 Thomson Technology MEC 20 MICROPROCESSOR ENGINE/GENERATOR CONTROLLER LCD DISPLAY Vavg 432 Aavg 60. 1 Freq 600 Displays the average generator voltage as follows: 3-phase system: AVERAGE LINE TO LINE VOLTAGE--Phases AB, BC, CA 1-phase system: LINE TO LINE VOLTAGE--Phases A to B Displays 3-phase the system: average AVERAGE generator LINE current as follows: A, B, C CURRENT--Phases 1-phase system: AVERAGE LINE CURRENT--Phases A, B Displays generator frequency in hertz (HZ). GENERATOR KVA DISPLAY The generator's total power output in kilo-voltamperes (KVA) is displayed. GENERATOR PHASE VOLTAGE DISPLAY (LINE TO LINE) The generator phase voltage screen allows the operator to view the generator AC voltage on all 3 phases (or single phase system as selected). LCD DISPLAY Vab Vbc 600 Vca 600 600 PM047 Rev 13 05/03/30 45 Thomson Technology MEC 20 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 9. 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 20 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. 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).
