CAUTION O
Make certain that the proximity switch is not mounted too high.
To check, carefully push the gantry/placement head over the proximity switch manually. 14
➠ Where applicable, mount the retaining bracket for the proximity switch in its earlier position,
Fig. 14.3.10 -> &).
➠ Make the plug-and-socket connection of X13 to SLIO module on PCB1 or PCB2.
Note: The strain on the wiring must be relieved after the cable ties are attached.
➠ Re-attach the cable ties and insert the cable duct cover.
➠ Perform the appropriate )LQDOVVWHSVLQFOXGLQJ)XQFWLRQ&KHFN(see section 14.4). Check
the function of the "Proximity switch for position of width adjustment system".
– The proximity switch must not be damaged when the gantry is moved.
– If the proximity switch is not being actuated, correct the triggering distance of the proximity
switch.

The sensing heads for the sonar proximity switches are positioned as follows (see ):
– In placement areas 1 and 2 or 3 and 4:
in the hold in the stopper base unit.
– On the input and intermediate conveyor (conveyor 1 / 2):
In the mount for the sonar proximity switch on the motor mount of the pertinent conveyor drive.
– On the output conveyor (conveyor 1 / 2):
With a bracket on the fixed side of the conveyor.
NOTE:
The assembly "Sonar proximity switch" consists of the sensing head and of theDPSOLILHU(see )
and the cable (not removable on sensing head).
It is also possible to exchange just the amplifier RUthe sensing head of the sonar proximity
switch.

➠ To remove the sensing head in the placement area first remove the Liftig table as described in
section 14.3.8.1.
➠ Use the caliper gage to ascertain the PRXQWSRVLWLRQof the sonar proximity switch sensing
head that is to be removed (measured to front surface of the proximity switch) and record the
dimensions.

In case of a problem with the sonar proximity switch sensing head:
➠ Loosen the clamping unit of the sonar proximity switch sensing head and pull out the sensing
head.
➠ For the electrical isolation, proceed through the following steps>
➠ Lift off the cover of the cable duct in question.
➠ Carefully (!) remove the corresponding cable ties.
➠ Run the cable of the faulty sonar proximity switch sensing head carefully (!) so that it
weaves its way as far as the sonar proximity switch amplifier (layout: see ).
➠ Pull off the plug-and-socket connection of the sensing head at the allocated amplifier (see ).
In case of a problem with the sonar proximity switch amplifier:
➠ Pull the cable of the sensing head at the faulty amplifier and loosen the screw connection of
the cable on the bottom of the amplifier.
➠ Loosen the screws fastening the corresponding amplifier package (2 hexagonal socket head
cap screws M 5 x 70, see ).
-> The RUGHU of the amplifiers in the package must be maintained.
➠ Remove the faulty amplifier.

➠ Where applicable, push the new sonar proximity switch VHQVLQJKHDG into the hole such that
the DVVHPEO\GLPHQVLRQmeasured is restored. Clamp the sensing head H[DFWO\in this po-
sition.
➠ Where applicable, insert the new sonar proximity switch DPSOLILHUV into the amplifier package
in the correct order and screw the package tight (see ).
Make the plug-and-socket and screw connection.
➠ Carry out all further assembly steps in the reverse order to that during removal.
➠ Remove all tools, etc., from the working area of the machine.
➠ Where applicable, fold down the transmission lever on the lifting table motor mount (see Fig.
14.3.5: illustration bottom left).
➠ Install the lifting table as described in section 14.3.9.2.
➠ Carry out the pertinent )LQDOVWHSVLQFOXGLQJIXQFWLRQFKHFN(see section 14.4). Use the
"Setting Instructions for HS-50" to calibrate the sonar proximity switch amplifier.

Key to Fig. 14.3.11
➠ Before removing the proximity switch, check the problem situation:
– If the control LED at the stopper does not light up in case of "Stopper moved out", the ac-
tuation distance is not set correctly or the supply voltage has been interrupted or the prox-
imity switch is faulty.
