Pressure setting is done by means of a proportional pressure
control valve which is activated by the proportional amplifier.
For pressure setting, the following steps have to be taken in
that order:
a) Set the “Dither” potentiometer at 50% (clockwise direction,
50% are 10 rotations = original manufacturer’s setting).
b) Set the speed at 100% for the “Withdraw nozzle” process.
c) Set the pressure at 10% for the “Withdraw nozzle” process.
d) Activate the “Withdraw nozzle” process and use the “I-min”
potentiometer to set a pressure of 21 bar (304.5 psi) at the
metering point MPS.
e) Set the pressure at 95% for “Withdraw nozzle” process.
f) Activate the “Withdraw nozzle” process and use the “I-max”
potentiometer to set the pressure at 200 bar (2,893 psi). The
maximum system pressure at 100% is 210 bar (3,045 psi).
