6.4 Calibrating the digital PRV
The digital PRV is part of the placement head and generates the vacuum and the blast air for the
pickup and placement process. The zero point calibration of the digital PRV must be performed on
initial startup by the customer and then checked again after replacement of the digital PRV or the
placement head and recalibrated if necessary.
The zero point calibration is used to set the motor in the digital PRV into a neutral or central posi-
tion so that there is no vacuum or air blast at the nozzle.

NOTICE
From SW706 this function is performed automatically (automatic calibration menu).
