(T-Series) Air-Cooled Genset Technical Data Sheet
Rating Definitions to ISO 8528-1
All ratings in the table are in accordance with ISO 8528-1.
Power Factor: Single phase, 1.0 pf; three-phase, 0.8 pf.
Voltages: Other voltages are available; refer to Lister Petter.
Power outputs are based on the optimum make of alternator for the set. Gensets fitted with other manufacturers’ alternators may not achieve the above ratings.
Rating Conditions
A standard generating set is designed to operate in environmental reference conditions of 25 °C, 100 kPa and 30% humidity.
Prime Power
This rating is for the supply of continuous electrical power (at variable load). There is no limit on the annual hours of operation and 10% overload power can be supplied for 1 hour in 12.
Standby Power
This rating is for the supply of continuous electrical power (at variable load) in the event of a utility power failure. No overload is permitted.
Optional Items:
- residential exhaust silencer for open sets (as fitted to acoustic version)
- AMF upgrade kit
- acoustic canopy kit (including residential silencer kit) for retro-fitting to manual/remote start open sets only
- 2-wheel trailer
- basic tool kit
Engine Specification:
- Lister Petter T-Series, air-cooled, direct injection, naturally aspirated diesel engine
- medium-duty air cleaner
- oil and fuel filters
- fuel-lift pump
- 12 V electric starting system
Alternator Specification:
- single-bearing, 4-pole brushless alternator
- solid state AVR with ±1.5% voltage regulation as standard
- class “H” insulation on the rotor and stator
- IP23 protection class
Control System Features
Control Cubicle:
All sets have a control cubicle mounted on a vibration-isolated support, which has the following features:
- automatic shutdown protection
- emergency stop button (lock-down type)
- AC output circuit breaker with over-current protection
- DC circuit control switch and overload circuit breaker
- automatic solid-state 4-Amp battery charger
- electronic digital control module with monitoring/control facility and warning indicators
The control module gives digital readouts of:
- generator voltage (phase-to-phase and phase-to-neutral)
- generator current (each phase displayed separately)
- output frequency
- engine speed
- battery voltage
- hours run
The control module has indicators for:
- overspeed/underspeed
- emergency stop
- engine oil pressure
- engine temperature
- failure to start
- battery charger failure
Automatic shutdown occurs under:
- low engine oil pressure
- high engine temperature
- overspeed/underspeed
- failure to start after three attempts
Manual/Remote Start Sets:
These sets have the flexibility of either manual or remote automatic operation:
- manual operation is by START and STOP push-buttons on the control module
- remote operation is achieved by connecting a 2-wire circuit to the relevant terminals on the control module and is activated by setting the control module to AUTO
Automatic Mains Failure Sets (AMF):
The AMF specification provides that In the event of a mains failure the generating set will automatically operate to supply the electrical load.
Automatic mains failure sets have the following additional features:
- wall-mounted cubicle governing automatic mains failure operation
- control module timer circuits set to delay start, delay transfer back to mains and delay stop to allow for engine cooldown
- solid-state automatic battery charger that maintains charge when set is not running
The wall-mounted cubicle features:
- mains monitoring unit to control set operation
- load-transfer contactors, mechanically and electrically interlocked (rated for set output)
- indicator for mains-on-load or plant-on-load
- switch allowing manual operation of the load-transfer contactor if automatic system fails and set is started manually
