Pneumohydraulic controller HP 036./HP 037.
The controller is factory preset to maximum speed. By turning the
fluid restrictor (see fig. below) by approx. 5 turns to the right, the po
-
sitioning speed is reduced by approx. 50 %. If the system should dis-
play a tendency to hunt, we recommend you reduce the positioning
speed.
The fluid restrictor screw is also locked by a protective cap and nut.
The pressure limiting valve on HP 036 is factory preset to ap prox. 20
bar and to approx. 30 bar on HP 037. Once the protective cap has
been removed and the nut loosened, the set pressure can be adjus-
ted (see fig. above). By turning to the left, the pressure is reduced
and thus also the positioning force. Adjustments should be carried
out only when idling.
The pressure limiting valve should only be actuated when the
system is at a standstill or idling. It can only be turned with
difficulty when under pressure.
We recommend you reduce the fluid pressure if no great degree of
positioning force is required as the fluid doesn’t heat up so much.
The positioning force can be read off the pressure gauge when the
positioning device is in its end positions. Once set, the nut can be re-
tightened and the protective cap replaced.
