Pressure setting procedure
The pressure setting procedure is valid for all
pressure compensators (AC, AD and AH).
1.
Make sure that the motor has been
supplied with the correct modulating
spring (ordering code and name plate
information should correspond).
2.
Install 0 - 600 bar (0 - 8500 psi) gauges
in port X1 and X5; refer to fig. 1.
3.
Turn the adjustment screw counter
clockwise to ensure that the threshold
spring is unloaded.
The distance between nut and screw
end is approximately 23 mm when the
threshold spring is unloaded.
Note!
The distance between nut and screw
end should not be more than 28 mm,
because of risk for loosing guiding of the
spring.
4.
Increase the system pressure (e.g. by
blocking the motor shaft) to desired
pressure setting (read the pressure in
port X5).
WARNING
In order to prevent injury to the technician or
the bystanders during the adjustment
procedure, all hydraulic functions on the
vehicle/machine should be disabled (e.g.
wheels raised off the ground, work functions
disconnected).
Avoid fast forward/reversed changes
that can damage the synchronizing
shaft.

5.
Start to turn the threshold adjustment
screw clockwise until the pressure in
gauge X1 starts to increase. Right
threshold pressure setting has been
reached.
Note:
One turn of the setting screw
corresponds to 57 bar (820 psi).
