GOLDCUP CONTROLS SERIES 600
PUMP CONTROL PRESSURE
MOTOR CONTROL PRESSURE
1. Set pump (motor) to zero (full) stroke by adjusting minimum (maximum) stop screw
(30).
2. Apply servo pressure to signal port of stroker. Adjust pressure from minimum to
maximum. Note the pressure at which unit just starts to stroke, and the pressure at
which the unit reaches the final stroke These pressures must be within the following
values:
If pressures are incorrect, use adjusting screw (18) to obtain correct pressure.
3. With minimum signal, unit shall return to starting stroke, pumps to zero, and motors
to full displacement.
4. With full control signal pressure on control port, set screw (19) for final stroke,
Pumps at full, and motors at 1/3 stroke. Lock adjustments and install acorn nut (16).
5. Increase and decrease control pressure between 0 and 450 psi (31 bar) several
times . Stroke should follow control pressure smoothly and proportionally. Full to mini-
mum or minimum to full stroke should be achieved in no more than two seconds.
Adjust control pressure up to 50% stroke from initial stroke, then adjust down from final
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.
