main switch
CAUTION
To avoid losing data, evaluate the following criteria before switching off your automatic placement system
(apart from in emergencies):
– Has the placement system finished transmitting machine, set-up and working data?
– Has the placement system finished processing the PCB?
– Has the placement system completed the run-up phase?
– Has the Windows NT operating system been shut down correctly?

The compressed air working pressure is set to 5,1 bar, although it may fluctuate between 5.0 and 5.3 bar.
The position of the compressed air unit is indicated by item 4 in Fig. 1.4.1
. The compressed air supply to the
automatic placement system can be interrupted using the shut-off valve (item 1 in Fig. 1.4.1
).
- You must remove the cover plate to use the shut-off valve.
- Turn the lever on the shut-off valve (item 1 in Fig. 1.4.1) from the vertical to the horizontal position.
- Watch the working pressure gauge and the pressure gauge for the compressed air supply to the stopper
(item 2 and 3 in Fig. 1.4.1
)
When the automatic placement system is switched on, the pressure discharges to 0 bar within 1 minute.

WARNING
NEVER disconnect compressed air lines while they are pressurized. Risk of injury!
