NOTICE
DLM4 head
The DLM4 head adjustment is carried out only for pick-up/placement circuit. The air regulator
of the forced air valve for reject circuit is not in use and must be closed.

► Use the following nozzle type to set the blast air
DLM3: 914
DLM4: 3004 or 3014
► Please press in the spring from the nozzle interface
during the measurement and read the value from the
display.

Flow chart determining air pressure values
When setting the blast air value with the compressed air
device and the air regulator, observe the following:
► Press the nozzle upwards during the measurement
process!!
NOTICE!
The blast air values shown in the "Measure blast air pres

sure" menu item at the screen of the station computer in
"Manual Operations" or in the SITEST program, do not
reflect the blast air values really set at the nozzle. They
are only for checking that the blast air valve is functioning
correctly. Therefore, do not use the values shown on the
screen to set the blast air. Instead, use only the values
determined with the compressed air testing device.

NOTICE
Adjustment of reject circuit not required
Reject circuit settings are not necessary for HF/X machines.
The air regulator of the reject circuit is closed for DLM4 heads.
NOTICE
Blast air circuits
The two blast air circuits are controlled via a single valve and therefore influence one another
mutually. However, the two air regulators can be used to set different pressures for each circuit.
NOTICE
Measuring sensor hose
Make sure the measurement sensor hose is fitted tightly on the nozzle.
