4.3.3.5 Proportional valve, proportional regulator X58
When switching the machine on at the main switch, air is supplied to all placement heads.
After the reference run is performed, the air can be switched of by software after a certain time
(as standard 2 min.) and no air run through the vacuum system of the placement heads.
It automatically regulates the internal machine pressure to 4.8 +0.1 bar for the placement heads.
Included within this regulator block is a pressure sensor which monitors the outgoing air pres-
sure. If the pressure is too low, the A/D converter provides an output of 24 VDC. This signal is
supplied via the CAN I/O module in section 4 (pressure too low) and via the CAN bus to the
machine controller. The valve is controlled by relais K2, located in section 2, main distributor,
relay K1 is not used.

4.3.3.6 Safety valve X60
Safety valve for controlling the compressed air for transport and tape cutter. Air supply for trans-
port and tape cutter is only present, after the start button is pressed and all safety requirements
are fullfilled (safety loop closed).

4.3.3.7 Pneumatic loop Cooling Y - Linear motor for Placement area 1/2
For the purpose of cooling the Y-motors an additional pneumatic system is integrated, which suck
the air from the environment, compress it by a compressor and blows it through a hose system to
each of the y-axis motor. The compressed air releases the motor on a lateral point.
The temperature of the Y-axis coils is monitored and when it exeeds 110 C, a message appears
at the monitor. To be very sure, the Y-axis does not get overheatet, is the reason for this simple
cooling system.
