GOLDCUP CONTROLS SERIES 800
MOTOR CONTROL PRESSURE
MOTOR CONTROL SPRING
ADJUSTMENT
3. Apply servo pressure to control port of stroker. Control port is on the same side as
the trimmer adjustment. Adjust pressure from minimum to maximum. Note the control
pressure at which motor just starts to de-stroke, and the control pressure at which the
motor reaches 25% stroke. These pressures must be within the following values:
If pressures are incorrect, control may be disassembled and adjustment made to the
spring preload. The following table may be used to determine adjustment required to
the nuts retaining the spring:
4. Increase and decrease control pressure between 0 and 450 PSI (31 bar) several
times . Motor stroke should follow control pressure smoothly and proportionally. Full
to min. or minimum to full stroke should be achieved in no more than two seconds.
Adjust control pressure down to 50% stroke from full stroke, then adjust up from min.
stroke to the same value. The control pressure at the two settings shall not vary more
than 50 psi (3.4 bar) from each other.
5. When control has satisfactorily passed test, remove stop assembly from control and
set the two internal nuts to prevent adjustment of minimum stroke below 25% of stroke.
Reassemble stop assembly on control.
