5 Troubleshooting
key: Complete self-test
– Checks compressor run time up to
the point when a specific pressure
is reached and thus for leaks in the
area of the compressor.
– In the case of two different
pressures, checks for leaks in the
pressure accumulator (p
s
) and for
the internal tightness of the valves.
– Checks for leaks in the area of
working pressure (p
w
) in the case
of two different pressures.
– Checks behavior during injection
at different pressures (short
continuous test).
If certain values are outside the specified
range, an error message is emitted. If this
recurs, inform Service.
key: Self-test to search for leaks
– Checks for leaks in the pressure
accumulator (p
s
) in the case of two
different pressures, as well as for
inner tightness of the valves.
– Checks for leaks in the area of wor-
king pressure (p
w
) in the case of two
different pressures.
If certain values are outside the specified
range, an error message is emitted. If this
recurs, inform Service.
