CONTROL ADJUSTMENTS
Manual Variable Pressure Control
Maximum Pressure Adjustment
CAUTION
The following procedure requires the
ability to induce a sufficient load to
create maximum system pressures.
Take the necessary safety precautions
for your application.
1.
Using appropriate adapters, tee two 10,000 PSI
gauges into the system pressure feedback ports of
the control.
2.
Start the prime mover and slowly accelerate to
rated rpm.
CAUTION
Due to linkage bias, etc. there may be
system pressure created immediately
upon starting the prime mover. Take
the necessary safety precautions for
your application.
3.
Stroke the control in one direction and, using a 1/8"
internal hex wrench, adjust the maximum pressure
limiting screw clockwise for less pressure or ,
counterclockwise for more pressure until the
desired pressure reading is achieved. The
adjustment range is 3,000 to 5,000 PSI. Consult
machine specifications for proper pressure setting.
Lock the adjustment screw in place with the 7/16"
hex lock nut; torque to 8-11 ft. lbs.
4.
Stroke the control in the opposite direction and
adjust the other maximum pressure limiting screw
to achieve the desired pressure reading. Lock the
adjustment screw in place.
5.
Stop the prime mover, remove the gauges and
adapters, and reconnect hoses to their original
locations.
