DESIGNED TO CARRY OUT ALL THE FUNCTIONS NEEDED FOR THE OPERATION AND MANAGEMENT OF THREE-PHASE (MONO-PHASE) STANDBY GEN-SETS V= 12 / V= 24 – Hz 50 / Hz 60, AND FOR DIRECT APPLICATION ON MACHINES. ALL THESE FEATURES IN A SINGLE BOARD The standard automation functions are entrusted to the following inputs from the GEN-SET: • • • • • • • • NO FUEL OVERLOAD HIGH TEMPERATURE LOW OIL PRESSURE ALARM EXTERNAL STOP ENGINE RUNNING INPUT GENERATOR CURRENT INPUT (C.T.) The system’s outputs are: • • • • • • • • • STARTING RELAY STOPPING IN EXCITATION STOPPING IN DE-ENERGISING MAINS CONTACTOR GENERATOR CONTACTOR ENGINE RUNNING – PROGRAMMABLE TIMING ALARM SIREN GLOW PLUG PRE-HEATING STARTING AT LOW RPM Inputs for: • • • MAINS V. PRESENCE SIMULATION GENERATOR V. PRESENCE SIMULATION EJP FUNCTION (FR) The controls available on the front panel are: § § § § § START BUTTON STOP BUTTON SIREN BUTTON F1 – F2 INSTRUMENT SELECT BUTTONS F3 – F4 FUNCTION SELECT BUTTONS The system manages an emergency Software and makes it available in the case of main system failure, ensuring basic operation. 2 AVAILABLE SELECTIONS Through a 4-position selector composed of two pushbuttons F3/F4, it is possible to select the GEN-SET’s functioning modes. (to avoid unwanted manoeuvres, buttons F3 –F4 should be held for 1") ATTENTION!! SUPPLY THE LOGIC MP5B AND BEFORE OPERATE TO THE GEN-SET, SETS THE SELECTOR (buttons F1/F2) IN “RESET” POSITION ~ SELECTOR IN POSITION: Operation blocking function. The selector in this position causes stopping sequence intervention and the TEST LED. The "TLG" control is disabled. Alarms supervision is guaranteed. System programming mode: "PROG." In this position it is possible to change the programming of the default timings (base values) and to visualise the lighting of the various leds. Alarm resetting function. The intervention of each alarm causes the flashing indication on the panel and siren excitement. The siren silencing push-button causes signal memorising and siren de-energising. To reset the alarm it is necessary to eliminate the cause and switch to the "RESET" position. “MANUAL” “AUTOMATIC” Engine starting is obtained with the "START" push-button. The "STOP" control directly activates the stop relay. The "TLG" contactor is disabled. All alarms are active. The start control depends on the presence of the engine running signal. Function for the automatic management of gen-set intervention. The engine control depends on the restoration or failure MAINS / forcing /undervoltage MAINS / overvoltage MAINS. If during engine operation the "STOP" button is activated, the system automatically proceeds with the immediate stopping sequence. The " TLG " closure depends on Generator voltage and frequency. Engine starting control is in automatic sequence. The programmed sequences are activated and stopping is obtained at "AUTO" position (with mains restoration) at "MAN" through a STOP button. An emergency stop is possible with the selector at "RESET" position or by directly pressing STOP at "TEST" position. The supervision of all alarms and of TLG control with mains failure is active. GEN-SET can work by means of a program (channel P.31) with user loads even 3with MAINS presence. DISPLAY FEATURES The possible choices are: AMP. / KVA - V~ - Hz - V= - Ch / OIL AMP. / KVA AMP. Visualisation of current delivered by the generator KVA Apparent power delivered by the generator (keep F1 pressed) V~ MAINS / GENERATOR voltmeter. With TLR closed the voltmeter indicates MAINS voltage. With the Generator running, the voltmeter measures the generator’s voltage; the measurement normally regards the R phase. Changing channel P.33 programming (see the reference table)is possible to view the sequence scan of the R - S – T phases. Hz Measurement of generator frequency. This measure is active with at least 80 Vac of generator voltage. V= Measurement of battery voltage; the measurement range reaches up to 51,2 V. The resolution is 200 mV. Ch / OIL Ch Shows the operating hours of the gen-set. (the decimal point list at the right indicates: no. of hours x 10 ) OIL Indicates the time elapsed since maintenance time programming (P.12) (keep F2 pressed) When the MAINS is restored, the MAINS voltage is shown; in case of GEN-SET starting, GENERATOR voltage will be shown until the generator comes to a stop. F1 F2 4 SYSTEM PROGRAMMING The MICRO P5B control system allows the user to program the gen-set’s main automation functions; the parameters are listed in the reference table (see the programming table). The control system, after the test phases, is supplied with the base programming (DEFAULT). The user can modify the table setting the led selector to "RESET"; in this position, the MICRO P5B control system executes a 3 second led test; after completion of the autotest it is possible to view the programmable channels from P.1 to P.34, using the cursors INCREASE - F1 REDUCE - F2 Pressing the siren silencer button the value (3 digits) of the channel selected is shown. The alteration of the default value (base value) is obtained by simultaneously pressing the siren silencer button and the INCREASE F1 / REDUCE F2 cursor. In case of programming errors it is possible to recall the main default table by simultaneously pressing the INCREASE F1 / REDUCE F2 button for at least 2 seconds. The parameters are memorised automatically when exiting the "RESET" function setting the led selector to the "MANUAL" position. The display shows the wording "MEM" to indicate that updating has taken place. 5 MAINTENANCE PROGRAMMING P.12 programmes the maintenance time (OIL). When the programmed time has elapsed the “OIL” message is shown on the display. The time elapsed can be viewed at all times: use the F2 button to select Ch/OIL. Then release the button. The next time the F2 button is pressed, and for the whole time in which it is kept pressed, the Service Time counted up to that moment will be shown. To delete the “OIL” message: • LED selector in the MANUAL mode. • Display = Ch/OIL. • Press the SIREN button + F2 for 3 seconds. PERIODIC START PROGRAMMING P.13 = start interval (0..99 days) P.14 = length of start (0..99 minutes) • Start count: after making a change in P.13, the count starts the moment PROGRAMM is excited (“MEM” on the display). • If at the end of the count the set is in the AUTO Mode with the engine stopped, starting is triggered. • If the cooling time is being performed at the end of the count, periodical starting is not triggered. • Programming P.13 = 0 cuts off this function. • At power-on the count is reset, and it starts if P.13 is not 0. 6 PROGRAMMING TABLE CHANNEL OPERATING RANGE DEFAULT GENERATOR STARTING DELAY MAINS FAILURE TIME 0 from 0 to 59 sec. from 1 to 15' 05 STOPPING DELAY AT MAINS RESTORATION MAINS RESTORATION TIME 1 from 0 to 59 sec. from 1 to 15' 05 LOW OIL PRESSURE ALARM ENABLING DELAY 2 from 0 to 99 sec. 05 STOPPING TIME 3 from 2 to 99 sec. 15 SIREN ENABLING TIME 4 from 0 to 99 sec. if 99 PERMANENT 60 STARTING TIME 5 from 1 to 20 sec. 05 NUMBER OF STARTING ATTEMPTS 6 from 1 to 10 03 TIME BETWEEN STARTS 7 from 1 to 20 sec. 05 ENGINE COOLING 8 from 0 to 59 sec from 1 to 15 minutes 30 ENGINE HEATING GENERATOR PRESENCE 9 from 0 to 59 sec from 1 to 15 minutes 05 GLOW PLUGS PREHEATING TIME 10 from 0 to 99 sec. 00 SET/RESET ENGINE RUNNING TIME 11 from 1" to 5' if 0 NO ACTIVE if ON PERMANENT ON ENGINE MAINTENANCE TIME 12 from 0 to 990 00 PERIODIC STARTING 13 from 0 to 99 days 00 PERIODIC RUN TIME 14 from 0 to 99 min. 10' BATTERY ALARM THRESHOLD 15 from 9,0 (9V) to 33,0 (33V) 10.0 MAINS VOLTAGE 16 from 70 V to 500 V (hysteresis 5%) 330 GENERATOR VOLTAGE 17 from 70 V to 500 V (hysteresis 5%) 330 MAINS / GENERATOR OVERVOLTAGE THRESHOLD 18 from 70 V to 800 V 440 GENERATOR OVER-SPEED / OVER-FREQUENCY 19 from 45 to 99 Hz 57 UNDER-FREQUENCY 20 from 0 to 99 Hz 47 WORKING PARAMETERS 7 PROGRAMMING TABLE CHANNEL OPERATING RANGE DEFAULT GEN-SET OVERLOAD – OVERCURRENT ALARM 21 from 0 to 1000 A. 0 GEN-SET OVERLOAD – KVA ALARM 22 from 0 to 4000 A. 0 MONO-PHASE / THREE-PHASE FUNCTION 23 Three-phase = 400 Mono-phase = 230 400 CURRENT TRANSF.
