| 2 | (i) 12V electrical starting system consisting of starter motor, charging alternator and 01 nos, 12V, 180 AH battery. (ii) Dry type Air cleaner with restriction indicator (iii) In-line Fuel injection system with Electronic Governor (iv) Spin-on Lube oil filter elements (iv) Radiator, Air-to- Air after cooler, pusher fan & fan drive arrangement, Gear driven water pump (v) Sensor for oil pressure, Coolant temperature & level (iv) First fill of Lube oil. (API CF4 grade, Greaves Maxtherm Lube or equivalent)
( B) ALTERNATOR:- Single bearing alternator suitable for continuous operation generating 100 KVA at 1500 RPM, 415 Volts, 0.8 power factor (lag) suitable for 50 Hz, 3 phase, 4 wire system confirming to BS 5000/ IS 4722, brushless type, screen protected revolving field, self excited, self regulated through an AVR. The alternator has the following features: (a) 1.0% voltage regulation (max) in static conditions (b) IP: 23 protection with insulated class H (c) Permissible overload of 10% for one hour in 12 hours of operation. Features, Functions, Protections (a) 16 character x 2 line alphanumeric LCD display with LED backlight (b) Operator Interface (c) Provide a record of most recent fault conditions, Fault history stored in the control non volatile memory (d) Provide Alternator data frequency.
Provide Engine data- Starting (a) Battery Voltage (b) Engine Temp | | |
| 3 | (c) Oil pressured (d) Engine Hrs run Control includes provision for service adjustment and calibration of DG control function (a) Voltage, frequency selection (b) Meter calibration
(c) Configurable input and output set up Power start operates on 24 V DC batteries Auto start mode accepts a ground signal from remote devices to automatically start the DG set. The remote start will also wake up the control system from sleep mode. Engine Starting The control system supports automatic engine starting, Primary and back up start disconnects are achieved by battery charging feedback or main alternator output frequency.
Controller provide configurable time delay of 0-300 sec to start after remote start signal and time delay of 0-600 secs prior to shutdown after stop signal.
Sleep mode increase battery life. Configurable current setting from low to minimize current draw when genset is not working.
Engine Protective Functions includes :- Configurable alarm output emergency stop: Annunciated whenever an emergency stop signal is received by the control (a) Low Lube oil pressure warning and shutdown (b) High engine water temperature warning / shutdown (c) Low coolant temp warning (d) sensor failure indication (e) Low and high battery voltage warning (f) Weak battery warning (g) Fail to start shut down (h) Cranking lockout: Control will not allow the starter to engage or to crank the running engine (j) Cyclic cranking: Configurable for the number of starting cycle (1 to 7) and duration of crank and rest periods | | |
