11.3 Optical Nozzle Query (Nozzle Scanning)
Fig.126: Nozzle scan
The nozzle scan can be enabled or disabled
in the software. Different scanning levels
and the corresponding actions for the errors
in individual nozzle types can be defined.
11.4 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 correction adjusts the pressure control valve to the ambient pressure.
11.5 Zero Point Calibration of Pressure Control Valve
The initialization (zero correction) of the pressure control valve (PRV) is performed at the same
time as the machine reference run.
To allow for the pressure control valve to work optimally, perform the following calibration steps in
the station software.
Perform this calibration in the following cases:
●
When exchanging the pressure control valve
●
When exchanging the placement head
●
When removing the placement head for maintenance and installing that same one afterwards
●
When error message 42466 is issued: Pressure control valve did not attain pressure threshold
for starting the Z axis.
Performing the calibration
ü Make sure that a calibration nozzle 6235 is inserted in segment 1 of the placement head.
