Functional Description

The integrated valve electronics

include the following functions:

• Differential command input for

voltage or current signals.

• Adjustable ramp generator.

• Flow offset adjustment (min.)

and deadband compensation.

• Maximum adjustment (max.) to

maintain full use of the command

signal range over the actual flow

spectrum set with this adjust-

ment.

• Pulse width modulated current

signals for both solenoids.

• Standard central connection

socket.

There is a linear relationship

between the solenoid current

and the input signal. The

solenoid current is stabilized

against voltage fluctuations as

well as temperature dependent

resistance variations of the

solenoid coil. Because of the

effect of load on the position of

the valve spool, the spool

position can vary and there is a

limited relationship between the

input signal and the valve flow.

Set-up procedure:

1) Feed in a command signal of approximately +200mV (or

+0.4mA) at the input PIN D.

2) Adjust offset for corresponding valve side by

potentiometer "MIN B". Adjust the potentiometer

clockwise until motion is detected, then back off one-half

turn.

3) Feed in a command signal +10V (or +20mA) at input

PIN D.

4) Adjust the required spool stroke (required flow) for

corresponding valve side by potentiometer “MAX B”.

5) Repeat this procedure with negative command signals for

opposite valve side using potentiometers “MIN A” and

“MAX A”.

6) Take into account that MIN has to be adjusted before

MAX.

7) See Block diagram.

Measurement and Set-up Procedure

Ramp time and adjustment diagram

The electronic ramp controls allow for adjustment of

acceleration and deceleration rate for smooth motion

of the load. “Ramp B” provides adjustment of both

acceleration and deceleration on B-side, “Ramp A”

controls both acceleration and deceleration on A- side.

The time can be adjusted from 0 to 3 seconds.

MIN-/MAX-Setup:

With the MIN-adjustments the deadband of the valve

spool can be compensated individually for both

directions, A- and B-side.

The MAX-adjustment feature adapts the full command

signal range to the defined actual working range of the

valve.
