3.2 Operating characteristics
(see fig. 3.1.1)
A set signal w = 0/4...20 mA generates a magnetic force FMag in the
VRM, the limits of which can be adjusted by means of the X0 and X1
potentiometers and which is then transmitted onto the control piston via
tappet.
The hydraulic force FHyd being proportional to the output signal pressure
PAacts against this force.
In the case of the two forces being equal, the control piston is positioned
in the “hydraulic center” as shown in fig. 3.1.1 and the output signal
pressure PAcorresponds to the set signal w.
In the “hydraulic center“ position the control piston performs minimum
oscillating movements in the area of the guiding edges P®PAand PA®T,
in order to keep the output pressure PAon the value set by FMag.
When increasing the set signal and thus FMag from this condition, the
control piston position changes and thus connects the output pressure PA
to the feed pressure P and blocks PAtowards the tank return line T1.
Now pressure PAand thus the hydraulic force FMag will increase until the
same has returned the control piston to the “hydraulic center” and PA
corresponds to the new set signal.
In case of I/H converters with regulating range 0..X a pressure spring is
installed between cover, item 8, and the control piston.
This spring generates a force-offset FFed towards the effective direction of
FHyd in order to guarantee the I/H converter function for output pressures
of approx. 0 bar, too.
The internal leakage is fed back into tank return line T2.
Function of manual operation knob:
The control magnet of I/H converter DSG-BXX112 is provided with a
manual operation knob, by means of which an adjustable spring force
can be set instead of the magnetic force FMag . This spring force affects
the control piston via magnet armature and tappet. The hydraulic force
FHyd , being proportional to the output signal pressure PAalso acts
against this spring force here. Thus adjustment of output pressure is
possible without electric connection.

7. Operation
7.1 Operation with manual knob
Operation with manually controlled rotary knob is possible without electric
energy.
On operation with manually actuated rotary knob, uncontrolled stroke
movements of the hydraulic components controlled by the I/H converter
output might occur due to the increase in the output signal pressure.
Manual operation is only possible when the circlip is removed from the
manual operation knob.
On completion of operation with manual operation knob, move the
manual operation knob in its final position by turning it counter clockwise
and pushing in the circlip to its final position.
·Remove the circlip.
·Slowly turn the manual operation knob clockwise and observe the
output pressure.
Effective direction: Output pressure increase by clockwise rotation.
7.2 Operation with set signal
When the supply voltage is switched on, the output signal pressure can
be adjusted continuously by the set signal 0/4...20 mA within the limits
set by the potentiometers X0 und X1.

7.3 Trouble shooting and remedial action
Prior to all works, make sure that the I/H converter was commissioned
according to chapters 5 and 6.
Malfunction: Pressure variations
The output signal pressure PAmay vary now and then or
periodically with low or high frequency and amplitude.
Cause: 1. air inclusions in the hydraulic component
2. low or considerably varying input pressure.
3. dirt particles in the hydraulic component
4. pressure on return line
Remedy: 1. On first commissioning or after longer periods of
stand still air inclusions in the hydraulic component may
cause pressure variations. Positive opening operation
grants sufficient hydraulic damping due to the damping
piston within seconds.
2. Under load and in particular in case of higher output
signal pressure, a lower input pressure may lead to
pressure variations.
Increase and / or stabilize the input pressure by taking
appropriate measures (e.g. accumulator). See also chapter
1.
3. Contaminated pressure fluid results in increased friction at
the control piston, thus causing hysteresis and pressure
variations.
Open hydraulic component and clean the inner elements. In
case of damaged surfaces and guiding edges replace the
I/H converter.
4. The dimensions of the return line have to be sufficient.
In case of additional consumers of the output pressure
connected to this line, make sure they do not create any
pressure in the return line. See also chapter 5.2.

3.626 - 018877 en D – 74564 Crailsheim
Malfunction: Output pressure PA ®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 hydraulic component 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 (e.g. chips).
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.
Repairs on the control magnet VRM are not allowed.
Replace any defective I/H converter completely.
8. Maintenance and Repair
For a 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
