®
is checked for leaks in the self-test.
This self-test can also be used if a leak is suspected.
The test runs automatically.
The pressure tube must be connected to a closed capillary
(e.g. melted closed or filled) for the pressure control to work
properly.
key: Complete self-test
–
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.
