De−rating factors at 0.8 pf continuous load:
Air in temp 20°C Continuous
Air in temp 30°C 5,7 KVA @ 0.8 p.f
continuous
Air in temp 46°C 4,5 KVA @ 0.8 p.f
continuous
De−rating factors for intermittant load:
Air in temp 20−35°C,55 mins/hr @ 0.8, 5 mins off load
Air in temp 35−40°C,50 mins/hr @ 0.8, 10 mins off load
Air in temp 40°C + ,45 mins/hr @ 0.8, 15 mins off load
Socket outlets:
110V 1ph & 230V 1ph 1 x 32 amperes
2 x 16 amperes
230V 3ph 1 x 16 amperes
400V 3ph + 230V 1ph 400V 3ph = 1 x 16 amperes
230V 1ph = 2 x 16 amperes
Earth leakage protection is provided by a single residual current
device. Miniature circuite breakers (MCB) are fitted to provide both
overcurrent and short circuit protection for the generator.
Each socket outlet is protected by a spring loaded weather-proof
cover.
OPERATING INSTRUCTIONS
A mode selector switch is provided to switch the machine between
compressor and generator mode.
CAUTION: Do not start or stop the machine with the
compressor/generator mode switch in the Generator position.
When the switch is in the Generator position the normally−open
solenoid valve switches to the closed position and air in the line to the
engine speed control cylinder vents to the atmosphere via the solenoid
exhaust port. This causes the cylinder to move to its maximum speed
position. The engine will now maintain maximum speed as the air line
from the pressure regulator valve to the solenoid valve is now closed.
When the switch is returned to the Compressor position, the
solenoid valve is de−energised thus returning it to its normally open
position. The engine speed cylinder would then respond via the
pressure regulator valve according to the air demand.
When connecting electrical equipment to any of the socket outlets,
it is recommended that the appropriate MCB is in the OFF position
before making the connection, switching the MCB to the ON position
immediately prior to using the equipment.
PRIOR TO STARTING (GENERATOR)
(WDG)
If the generator should become exposed or saturated with
moisture/water deposits, it must be safely dried off before attempting
to make any part or conductor electrically live. This should be done by
wiping away excess water, then running the engine with no electrical
loads connected, until the generator is completely dry.
Ensure all persons concerned are suitably competent with electrical
installations.
Ensure that there is a safe working procedure which has been
issued by supervisory personnel, and that it is understood by all
persons concerned with the operation of the generator.
Ensure that the safety procedure to be applied is based on the
appropriate national regulations.
Ensure that the safety procedure is followed at al times.
Ensure that suitable guidance codes are available to indicate safe
working practices, and any hazards to avoid.
Before starting the engine and switching in the generator load,
ensure that :−
. The system has been inspected and earthed.
. No persons are in a hazardous position.
. Any warnings necessary have been suitably displayed (where
applicable).
Ensure compressor / generator mode switch is set to compressor.
