Design
The electronic plug-in type amplifier pQ 11 is used to control proportional pressure and directional control valves. It is mounted directly on the proportional solenoid and secured by means of a screw.
Function
The amplifier supplies a direct current for the control of the proportional solenoid. This current is proportional to the set point at the amplifier input. In conjunction with a proportional valve, this allows a pressure or a flow to be set to any desired value.
Accessories include set point adjusters.
l Control of one solenoid l Mounts directly on valve body l Standard voltage and current signals for set point inputs l Control from computer also possible l Impressed solenoid current, thus no change in the controlled variable due to environmental influences l
(e.g. temperatures and mains fluctuations)
Plug-in type connection for proportional solenoid with contact arrangement to DIN 43650, Type A or B.

Trimming potentiometer E "A B" (p/Q)
If the customer-specific working range represents only part of the valve adjustment range, the trimming potentiometer
"A B" can be used to match the working range to the full set point signal from 0 to 100%. This provides the possibility of assigning a defined pressure or a defined flow volume to the end point in order to obtain greater resolution.
Adjustment: Trimming potentiometer D1 "NUL"
Preselection: Jumper D2
(for instructions to this see Page 7)
Zero-shift (Fig. 1)
(Jumper D2 to position "OFS" = offset)
Via the trimming potentiometer "NUL“ the solenoid current can be increased. This provides the possibility of assigning a defined pressure or defined flow volume to the start point
(set point = 0)
Zero-step function (Fig. 2)
(Jumper D2 to position "SPR" = jump)
By means of the zero-step function, valve overlapping can be eliminated.
As soon as the setpoint adjustment is exceeded by more than 2% the solenoid current is raised corresponding to the adjustment of the trimming potentiometer "NUL". This way it is assured that with set point = 0 the solenoid current is
0 mA.
Fig. 1
(Fig. 3)
Trimming potentiometer F2 "RMP"
The ramp module provides a ramp-like change of the solenoid current if the set point changes abruptly. The final value of the solenoid current thereby corresponds to the set point. The adjustment time between two working points can be adjusted, measured with a set point change of
100%. By means of jumper F1 the ramp shaper can be disconnected.
Fig. 2
Trimming potentiometer C2 "OSZ"
In order to improve the hysteresis characteristics in a valve, static friction on the valve piston must be avoided. This is achieved by superimposing a dither signal on the valve current. Via the trimming potentiometer "OSZ" the amplitude of the superimposed current can be adjusted within the range of 0 to 30% of the rated current. Optimum setting is achieved when small changes in the set point are registered on the final control element. The minimum dither amplitude possible should be used at all times.

1.1 Supply: 18 ... 32 VDC, excess voltage leads to amplifier defects.
1.2 The plug-in type amplifier should not be installed too close to a power relay.
1.3 The conductors to the external set point adjusters
(drive) must be screened. The screening must be connected on one side to terminal 2.
(below order must be strictly adhered to).
2.1 Preselection of set point

2.3.2 Imposed dither (amplitude)
On trimming potentiometer C2 "OSZ"
For adjustment of the dither a setpoint

sure has been reached with the setpoint
adjusted to zero.
2.4.2 Zero-point jump
a) Switch jumper D2 to position "OFS"
b) Adjust setpoint to zero
c) Turn trimming potentiometer D1 "NUL" clockwise until the valve opens. Then turn it anticlockwise until the valve has closed again.
d) Switch jumper D2 to position "SPR"
2.5 Drive limitation
Trimming potentiometer E "AB"
a) Turn trimming potentiometer E "AB" approx. 12 counterclockwise
b) Adjust set point to max. value
c) Turn trimming potentiometer E "AB" clockwise
until the desired value of the flow volume or
pressure has been reached.
2.6 Ramp shaper
2.6.1 Ramp off
Switch jumper F1 to position "OFF"
2.6.2 Ramp on
a) Switch jumper F1 to position "ON"
b) Set trimming potentiometer F2 "RMP" to the
longest adjusting time by turning it clockwise.
c) By turning the trimming potentiometer F2
anticlockwise set the adjusting time so that the
desired transient response is achieved when the
set point is changed.
3.1 Measure the amplifier supply voltage
(+18 ... 32 V) between terminals 5 and 1, if necessary, check the supply cable and the fuse in this.
3.2 Measure the internal amplifier operating voltage
(+15 V) between terminals 4 and 1.
3.3 Measure the set point input signal
between check points Mp2 and Mp1
Measuring values according to table.

3.4 Measuring the solenoid current
The solenoid current can be measured by means of a
voltmeter.
Check point Mp3 (solenoid current).
Measure U
Mp3
= f (I
solenoid
) for measurement of sole-
noid current by means of a voltmeter with R i
≥ 1 M Ω.
For assignment, see table.
Definition U = f (I
Solenoid
)
Type Assignment Measured value
(measured against
Mp1)
0 ... 1000 mA 1 mV corresp. to 3 mA 0 ... 325 mV
0 ... 2400 mA 1 mV corresp. to 10 mA 0 ... 240 mV
Measure between check points Mp3 and Mp1 and,
in the case of a plug-in type amplifier, also between
plug pins 2 and 6.
With setpoint = 0, the solenoid current must be 0 mA
(measurement 0 mV). The trimming potentiometer for
zero-point lift "NUL" must be set to zero (left-hand stop).
Important: The solenoid current can be measured only when the amplifier on the solenoid is plugged in.
