Pressure Limiter Setting
Ports A and B (differential
pressure in 10s of bars,
e.g. “35” = 350 bar)
5. The factory preset pressure limiter setting is shown
on the model code as at right. It is referenced to
charge pressure, so the pressure limiter setting is the
difference between the high and low pressure sides
of the system loop. Activate or move the control input
so that pressure increases in the high pressure side
of the closed circuit to the pressure limiter pressure
setting. The pressure limiter setting is reached when
the pressure stops increasing and remains steady at
a given pressure level (as shown on the gauges).
6. Return the pump to its “neutral” (zero flow) position
and adjust the pressure limiter setting by rotating the
pressure adjusting screw with the internal hex wrench.
Clockwise rotation of the pressure adjustment screw
will increase the pressure setting, and counterclock-
wise rotation will decrease the pressure setting. Each
complete rotation of the pressure adjusting screw
changes the pressure as shown in the following table.

7. To verify the actual pressure setting, actuate or move
the control input so that the pump again develops
pressure in the high pressure circuit to the newly
adjusted pressure limiter pressure setting, and read
the high pressure gauge. Then allow the pump to
return to its “neutral” position. The pressure in the
high pressure circuit should return to the charge
pressure setting.
8. While holding the pressure adjusting screw station-
ary, tighten the pressure adjusting screw lock.

9. Shut down the prime mover, remove the gauges and
install the gauge port plugs. Replace the plastic dust
plugs (if used).
The same procedure is used for setting the pressure limit
of the other multi-function valve, but the control input
signal must be activated or moved in the opposite direc-
tion so that high pressure develops in the opposite side
of the closed circuit.
