After selecting a pressure of appr. 70 bar (1015 psi) and a
material quantity of appr. 50%, the “Withdraw nozzle”
movement adjusts the p setting of the output regulation of the
variable capacity pump. The control block connection points
MPP (pressure before quantity decrease) and MPS (pressure
after quantity decrease) are used as measuring points.
The measuring process should be carried out using the same
pressure sensor and hydraulic pressure.
The pump output regulator should be set at 10 bar (145 psi)
p.
ATTENTION !
All pressure and speed settings must be carried out at an
oil temperature of 45°C (113°FAR).
