The incoming air supply passes through the moisture trap filter into the main regulator. This reg-
ulator regulates the internal machine air pressure to 5.3 bar. Included within the regulator block is
a pressure sensor, which monitors the incoming air pressure. The analogue output of this pres-
sure sensor is supplied to an A/D converter which when the incoming pressure reaches 5.3 bar
gives an output of 24 VDC. This signal is supplied to the machine controller via the SLIO I/O func-
tion and the CAN-bus.
NOTE
This pressure sensor can be damaged if the machine is turned on without compressed air sup-
plied to it. Therefore if the compressed air supply fails, turn off the machine.
The 5.3 bar is supplied to the following elements: - The collect & place heads through a shut off
valve, the PCB stoppers, the nozzle changers, the tape cutters and the feeder tables.
A further adjustable regulator is used to reduce the 5.3 bar to 2.3 bar. This supply is used for the
supply air for the optional bulk case feeder rail.
