[ ] = Reference to the block circuit diagram
3.1 General
The command value card is designed as printed circuit board in Euro-format 100 x 160 mm
and is suitable for installation in a rack. A power supply unit [1] provides the internally
required positive and negative supply voltages. As soon as the power supply unit is in opera-
tion and no error is present, the green LED on the front panel lights up and the “ready for
operation” signal is set.
3.2 Command value preselection
The internal command value signal is generated from the sum (command value summation
[6]) of the external command value signal applied to differential input [2] and to current
input [3], called-up signal [4] and zero point offset [5] (zero point potentiometer "Zw”).
3.3 Current input [3]
There is no changeover between current and voltage input. Both inputs are permanently
available (see terminal allocation). The input signals are internally normalized and added.
The zero point and the range of values of the current input can be changed over by means of
jumper J5.
3.4 Command value call-ups [4]
Four command value signals, “w1“ to “w4“, can be called up. External command value
voltages (command values 1 to 4) are preselected either directly via the regulated voltage
inputs + 10 V and – 10 V or via external potentiometers. If the command value inputs are
connected directly to the regulated voltages, the command values are adjusted by means of
potentiometers “w1“ to “w4“. If external potentiometers are used, the internal potentiom-
eters act as attenuators or limiters.
Only one call-up is possible at a time. If several call-ups are selected simultaneously, call-up
“1” has lowest priority, call-up “4” highest priority.
A yellow LED on the front panel indicates, which call-up is active.
3.5 External command value potentiometer
3.6 Command value inversion [7]
The command value that is generated internally from input signals, command value call-ups
and zero point offset signals can be inverted by means of an external signal or jumper J1.An
LED (“– 1“) on the front panel signals whether an external inversion signal is applied.
3.7 Enable function [8]
The enable function cuts the enable signal of the ramp generator in or out.When the enable
is cut in or out, the control variable changes at any command value according to the set ramp
time. This prevents a controlled valve from opening or closing suddenly. If an error signal is
present, the input signal of the ramp generator is also set to 0 %.An LED on the front panel
signals that an enable signal is applied.

3.9 External ramp time adjustment
The internally set ramp time can be extended by means of an external potentiometer. The
setting can be verified with the help of the measuring socket. In the case of a cable break,
the internal presetting will be validated automatically.
The adjustment range depends on "R".
2) The minimum ramp time can only be achieved, if the internally set ramp time is less, i.e.
the relevant potentiometer is turned to the left-hand stop.
3.10 Ramp status signal [11]
The status signal“ramp ready“ indicates that the control variable has reached the requested
final value. This signal (24V output) facilitates the synchronization of higher-level sequence
controls with the valve function or the controlled hydraulic function.
3.8 Ramp generator [9]
The ramp generator limits the increase of the control variable. Downstream step-functions
and amplitude attenuators do not shorten or extend the ramp time.
Jumper J2 can be used to set the ramp time to minimum (< 2 ms) (ramp off).
The minimum/maximum ramp time can be changed between 20 ms/5 s or 0.2 s/50 s by
means of jumper J3.
5 different ramp times can be set and activated. The ramp times can be pre-set or verified
with the help of test socket “v”.

3.11 Ramp time selection logic [10]
a) Operating mode "4-quadrant operation"
When 4-quadrant operation is activated (24V signal “4Q”), the electronics automatically
recognizes the command value polarity and the direction of change of the command value
and assigns a ramp time to the current signal status. Depending on these signal states, one
of the 4 ramp times is selected.
Ramp up, positive →Ramp potentiometer “t1”
Ramp down, positive →Ramp potentiometer “t2”
Ramp up, negative →Ramp potentiometer “t3”
Ramp down, negative →Ramp potentiometer “t4”
4-quadrant operation has a higher priority than all ramp time call-ups. As long as a signal
changes, the LED (on the front panel, directly next to the associated potentiometer) assigned
to the current ramp time lights up.
Note: In the case of very short ramp times, the LEDs' lighting up can no longer be noticed.
LED “4Q” on the front panel is on when quadrant recognition is active.
b) Ramp time call-ups
When operating mode "4-quadrant operation" is deactivated,4 ramp times can be called up
using an optional call-up signal (24V input). Only 1 call-up is possible at a time. If several
call-ups are activated at the same time, call-up “1” has the lowest priority and call-up “4”
has highest priority. Each called-up ramp time is signaled by a yellow LED (on the front panel,
directly next to the associated potentiometer).
c) 5th ramp time
If neither quadrant recognition nor a call-up is activated, ramp time "t5" is always valid.
3.12 Characteristic curve generator [12]
The adjustable characteristic curve generator can be used to adjust step-change heights and
maximum values separately for positive and negative signals according to the hydraulic re-
quirements. The actual characteristic curve shape through the zero point is not step-like, but
linear.
The step-change height can be adjusted by means of potentiometers "S+" and "S–".
Jumper J4 can be used to activate the step function. For this, the connection 2-3 of jumper J4
must be plugged (factory setting: connection 1-2 →step function OFF). To prevent a re-
sidual step-change (< 1 %) when the step function is deactivated, the potentiometers “S+”
and S–“ must be turned to the left-hand stop and the connection 1-2 of jumper J4 must be
plugged.
The maximum command value can be adjusted by means of potentiometers “Gw+” and
“Gw–”. The adjustment range is between 0 % and 110 %.
3.13 Amplitude limiter [13]
The control variables (current output and voltage output) are limited to approx. ±110 % of
the nominal range.

3.14 Fault recognition [14]
This features monitors internal operating voltages, voltage outputs and, if jumper J7 (1-2) is
plugged, the current output for cable break. When no fault is present, the green “ready for
operation” LED lights up and the output “ready for operation” is set to 24 V (operating
voltage).
3.15 Measuring points [15]
A measuring socket is provided on the front panel to allow the verification of the settings of
command value call-ups, ramp times and further, internal signals. The measuring points can
be selected using the measuring point selector switch that is also provided on the front
panel. The signal of the measuring socket is also connected to the blade connector (b26).

potentiometer "Zw" 1)
– Turn measuring point selector switch to "0"
–
Set the required step-change height using potentiometer "S –"
– Adjust the zero point
1) In the case of external command value preselection, this
must result in at least + 0.3 V / – 0.3 V at measuring
socket "v" (turn measuring point selector switch to "7").
Maximum values Note: Before the maximum values are matched, the zero
point and step-change heights must be correctly set.
– Adjust the step-change heights first; generate command
value ±100 % externally or by means of a command value
call-up
– Turn measuring point selector switch to "7"
– Check measuring signal 10 V ±0.2 V
– Adjust the required maximum control output using
potentiometers "G+"/"G–"

notes / supplem. information
– The command value card may only be withdrawn or plugged in when disconnected
from the power supply!
– Never install cables near power cables!
–
The distance to antenna cables, radio equipment and radar systems must be at least 1 m!
– Use relays with gold-plated contacts for switching command values (small voltages,
small currents)!
– Only carry out measurements on the cards with instruments Ri> 100 kΩ!
– Use a screw driver with a blade width of 4 mm for adjusting potentiometers and
turning the measuring point selector switch.
– Always shield command value cables; connect shield to protective earth (PE) on the
card side!
–Caution: When using the differential input, both inputs must always be
switched on or off simultaneously!
If the sealed potentiometers are misadjusted, the warranty will become void !
