6.13.5.2 Replacing the proximity switch for width adjustment systems 1+2 (00363777-01)
The proximity switch on the adjustment unit cylinder should operate when the adjustment unit pin
is pushed out by the pneumatic cylinder and therefore connected to the conveyor side. This signal
enables the motor of the width adjustment system.

Æ Move the PCB conveyor to the position which allows you best access to the adjustment unit.
Æ Move the Y-gantries into the area outside the PCB conveyor.
Æ Turn the machine off at the main switch and disconnect the machine from the mains voltage.
Æ Switch off the compressed air supply.
Æ Make sure the machine has been properly secured to prevent it being switched on again during
servicing.
Æ Loosen the grub screw on the proximity switch (see also Fig. 6.13.27) and move the proximity
switch out of the lifting table guide rail.
Æ Extract the connection cable as far as the conversion board of the mounting tray.
Æ Run the connection cable for the new proximity switch.
Æ Insert the new proximity switch into the guide rail.
Æ Switch the machine on.
NOTE
The width adjustment system proximity switch is set adjusted in engaged mode.
Æ Move the width adjustment system until the proximity switch switches - LED (H36/H37) lights
up.
Engage the cylinder - i.e. the cylinders are moved to the upper limit by the controls
Æ Set the proximity switch so that the LED lights up when it is in engaged mode.
Æ Fix the position of the proximity switch with the grub screw.
6.13.5.3 Replacing the proximity switch for adjustment units 1+2 (00363775-01)
The proximity switch serves as a signal for controlling the pneumatic valve of the adjustment unit.
Once the switching point has been reached, the conveyor side is connected via the short-stroke
cylinder.

Æ Loosen the grub screw on the clamping device (see also Fig. 6.13.27) and extract the connec-
tion cable as afar as the conversion board of the mounting tray.
Æ Insert the new proximity switch and reconnect to the electricity supply.
Æ Fix the proximity switch with the grub screw. The proximity switch must be level with the ad-
justment unit housing.
Æ The switching point is set at the actuator on the conveyor side.
Move the adjustment unit to under the conveyor side (see also Fig. 6.13.28
).
Æ Place a gauge block of 2/10mm on the adjustment unit, press the actuator onto the gauge
block and tighten the screw.
NOTE
This setting must be performed at all conveyor sides.
