Hydraulic Motor/Pump
Series V14
Gauge ports EO/EP/HO/HP
The pressure/current setting procedure is
valid for all proportional and two-position
controls (EO, EP, HO and HP).
1.
Make sure that the motor has been
supplied with the correct modulating
spring (ordering code and nameplate
information should agree). The hydrau-
lic oil should be 50°C (120°F).
2.
Install 0 - 600 bar (0 - 850 psi) gauge in
port X2. Use a 0 - 60 bar (0 - 850 psi)
gauge to measure pilot pressure if it is
a HO or HP.
3.
Turn the adjustment screw counter
clockwise to ensure that the threshold
spring is unloaded. The distance
between nut and screw end is
approximately 22 mm when the
threshold spring is unloaded.
Note!
The distance between nut and screw
end should not be more then 27 mm,
because of risk for loosing guiding of the
spring.
HO or HP controls
4.
Pressurize port X5 to desired threshold
(the control goes to min displ.).
Standard factory setting is 10 bar.
Optional setting is 5 - 25 bar.
EO or EP controls
4.
Apply the desired threshold current to
the solenoid (the control goes to min
5.
Start to turn the threshold adjustment
screw clockwise until the pressure in
gauge X2 starts to increase. Right
threshold pressure setting has been
reached.
Note:
One turn of the setting screw
corresponds to:
•
40 mA on 12 VDC solenoids (EO, EP)
•
20 mA on 24 VDC solenoids (EO, EP)
•
2,1 bar (30 psi) on HO and HP controls
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.
