Malfunction: Output pressure P
A
→
0 bar or
→
P (input pressure)
Due to a defective control valve VRM or blockage of the
control piston the output pressure may fall to 0 bar or
increase to the input pressure.
Remedy: The function of the component part can be checked using the
manually controlled knob with the supply voltage being
switched off. See chapter 7.1.
If the output pressure cannot be adjusted manually, the control
piston, e.g., may be blocked by particles.
Open hydraulic component and clean inner parts.
If the surfaces and guiding lines are damaged, exchange
the I/H converter.
Should output pressure adjustment be possible with manual
operation knob, but not with the control magnet, the control
magnet VRM is defective.

Maintenance and Repair
For trouble-free and reliable operation of the I/H converter, it is
necessary to perform inspection, maintenance and repair work in
certain intervals.
Routine inspection:
Check the pipes, screw connections and connections on the
I/H converter for leakage, impurities and damage.
Eliminate any leakage, impurity and damage noticed, if required, during
appropriate operating modes.
Monitor the control behavior of the I/H converter for any changes.
Analyse and eliminate the causes, if required, during appropriate
operating modes.
