DURING OPERATION
Regularly carry out following checks:
1. That regulating valve (see section
RV) is correctly adjusted, i.e. starts decreasing the
engine speed when reaching the preset working
pressure in the receiver.
2. Check the air filter vacuum indicators (see section
, VI). If the yellow piston reaches the
red marked service range, replace the filter
element. Reset the indicators by pushing the reset
button.
3. On compressors with aftercooler, check that the
automatic drain of the water separator is operative
without air leakage.
STOPPING PROCEDURE
1. Close the air outlet valves (see section
, AOV).
2. Run unloaded for 3 minutes.
3. Turn the start switch S1 counterclockwise (CCW)
to position 0.
4. Push the circuit breaker button (F1) once (open
hood first). Circuit breaker button should now be
in position A.
FAULT SITUATIONS AND PROTECTIVE
DEVICES
•
A fault which occurs with the engine, either: oil
pressure (too low), oil temperature (too high) or
alternator voltage (too low) will always and
immediately cause the engine to cut out and the
control lamp H2 will light up. By doing some
simple checks, it can be determined what it was
that caused the engine to fail: low oil level,
clogged-up cooler, slack alternator belt tension or
broken belt.
•
When the outlet temperature of the element
becomes too high, a thermocontact will also
switch off the group immediately. Both control
lamps H1 and H2 will light up. Both control lamps
will remain on until the group has been restarted
(start switch to position 3) or the contact is turned
off (start switch to position 0); also when, due to
cooling off, the thermocontact has closed again (=
memory function).
When the engine is running, the air
outlet valves (ball valves) must always be
put in a fully opened or fully closed
position.
The hood must be closed during
operation and may be opened for short
periods only.
