Lamps
H1.....Alternator charging indicator lamp
Goes out after starting, indicating that the alternator is charging.
H2.....Low fuel level alarm lamp
Starts flashing when there is only fuel left for approx. half an hour of
operation.
H3.....Air filter servicing alarm lamp
Starts flashing if the air filter elements need servicing.
H7.....Engine coolant temperature fault indicator lamp
Starts flashing if coolant temperature is too high.
H8.....Engine oil pressure fault indicator lamp
Starts flashing if the engine oil pressure is too low.
H9.....Compressor temperature fault indicator lamp
Starts flashing if the compressor element outlet temperature is too
high.
H10...Engine coolant level fault indicator lamp
Starts flashing if the coolant level is too low.
H11...Fuel level fault indicator lamp
Lights up if the fuel level is too low.
H13...Warming up indicator light
Indicates that the engine is warming up or cooling down
H14...Automatic load indicator light
Lights up when automatic load is chosen and the compressor is
waiting for loading.
H15...Manual load indicator light
Lights up when the compressor is loaded.
ADDITIONAL CONTROLS AND INDICATORS
The compressor contains a number of controls and indicators which
are not situated on the control and indicator panel.
H22...Flasher light
Located above the front service door. Starts flashing when the air
filters need to be serviced, when there is only fuel left for half an hour
of operation or in case of a shutdown.
SG.....Sight glass oil level
The sight glass is located next to the air receiver and indicates the oil
level in the air receiver.
TG.....Compressor element air outlet temperature gauge
Located behind the front service door and indicates the temperature of
the air at the outlet of the compressor element.
PG.....Pressure gauge, low pressure compressor element
Located behind the front service door. The gauge indicates the
pressure after the first compression stage or, in other words, after the
low pressure compressor element.
SHUTDOWN SWITCHES
The following shutdown switches, causing the engine to stop in
activated position, are provided:
S5 .....Engine oil pressure shutdown switch
Located on the engine oil filter housing.
Closes at rising oil pressure and opens if the oil pressure drops below
the setting of the switch.
S7.....Compressor low pressure element air outlet tempe-
rature shutdown switch
Sensing element on air outlet of compressor low pressure element.
Normal closed switch. Opens if the air outlet temperature exceeds the
setting of the switch.
S8 .....Compressor high pressure element air outlet tempe-
rature shutdown switch
Sensing element on air outlet of compressor high pressure element.
Normal closed switch. Opens if the air outlet temperature exceeds the
setting of the switch.
S14 ...Engine coolant temperature shutdown switch
Located on the water manifold on top of the cylinder head.
Normal open switch. Closes if temperature rises above the setting of
the switch.
S37:1.Low fuel level shutdown switch
Located in the fuel tank.
Normal open switch. Closes if the fuel level becomes too low.
B12 ...Coolant level sensor
Located in the coolant tank.
The coolant level sensor sends an analog signal to the control module
when the coolant level in the coolant toptank is sufficient. The signal
will be interrupted if the coolant level becomes too low.
