Set upNOTE The chopper amplifier has to be adjusted on-load (with connected prop. solenoid).

Never disconnect the solenoid while the operating current is connected.

To get optimal results and to avoid defects on the chopper amplifier and the valves, adjust the chopper amplifier with the following instructions

Adjust minimum current (Imin) always before maximum current (Imax).

Potentiometer control

Two-point control

► Connect supply voltage (see figure).

► Connect external potentiometer (see figure).

► Switch on hydraulic supply.

► Observe the function of the valve.

► Set external potentiometer to minimum value.

► Adjust the Imin potentiometer so that there is no hydraulic outlet (pressure or volume flow).

► Set external potentiomter to maximum value.

► Adjust the Imax potentiometer so that the desired max. pressure or volume flow is reached.

► The chopper amplifier is adjusted. The desired adjustment range is between the minimum value and the maximum value.

► If there is still a dead range, repeat the basic adjustments (Imin and Imax).

► Adjust the ramp potentiometer to the desired value (0-5s).


► Connect selector switch (min./max. value, see figure).

► Adjust selector switch to minimum value (1 to 4 connected).
