CAUTION O
During disassembly and assembly of the control unit and all work inside the machine base, make certain that
you do not damage the cables or exert any strain on them.
Do not pull an existing cable harnesses and do not move them out of their position.
DANGER OOO
Exchanging the cable "coplanarity - terminal panel" and any other work on its wiring constitutes interven-
tion in the safety circuit of the laser shut-off.
For this reason, the laser shut-off must always be checked explicitly afterwards (see "Checking the Safety
Circuit", Section 12.6.15).
Only
the Siemens service engineer is permitted to perform any work on connector X98 and the cable har-
ness "coplanarity" beyond exchanging the above-mentioned cable (see corresponding text in Fig. 12.6.3).
If necessary, use an insertion aid.
● Unplug the connector of the "sensor cable coplanarity" from the module coplanarity processing unit
(see Fig. 12.6.7).
● Paying attention to the above NOTE, carefully remove control unit Y0900.
● Carefully run the cable ties along the cable harness extending from control unit Y0900 to X211/21 in the
bottom cable duct of the input/output terminal panel Y0904.
● Remove the 2-core cable "coplanarity - terminal panel"
(see Fig. 12.6.3).
● Route the new 2-core cable "coplanarity - terminal panel" (Item No.: see Section 12.6.2) from control
unit Y0900 -> to the bottom cable duct of I/O terminal panel Y0904 X211/21(see Fig. 12.6.3).
● Lay the new cable next to the existing cable harness.
● Wire the cable "coplanarity - terminal panel" to the 15-pin, connector X98, on the back of the control
unit and to X211 / 21 on terminal panel Y0904.

CAUTION O
Do not exert strain on the wiring.
● Using cable clips, fasten the new cable to the existing cable harness.
● Make certain that the main cable harness is correctly attached inside the machine base and that the cables
are not pinched later when the control unit is installed.
● Re-install control unit Y0900.
● For the time being, do not plug the connector of the "sensor cable coplanarity" into the coplanarity pro-
cessing unit (see Fig. 12.6.7).
DANGER OOO
Pay attention to the above DANGER note.
● The next step is to check the laser shut-off unit (see Section 12.6.15)!

DANGER O O O
A 2nd strong person must always be available for the installation of the component table and the cutter.
There is a risk of being crushed or cut (see DANGER text in Section 12.6.1).
The re-installed component table or component changeover table must always be completely equipped with
feeder modules or dummy modules (see safety instructions in the User Manual).
● Hook the empty-tape slide back in place.
● Install the old cutter or the "pneumatic cutter" and the empty-tape duct:
Proceed exactly as described in the appropriate SIPLACE Service Manual under "Cutter....(see also
Section 12.6.2, under "Documentation").
● Make certain that the warning signs shown in Section 12.6.1 are on the coplanarity sensor.
For this laser class, no warning signs are required on the machine itself or on the safety hoods: see Sec-
tion 12.6.1.
● Place the metal dust cover into the conveyor trench in such a manner that it is lying on the contact sur-
faces of the sensor bracket (see Fig. 12.6.8 -> 12).
● Tighten the screws fastening the dust cover to the machine base (three or four washers and M4 socket-
hex cap screws: see Fig. 12.6.8 -> 15).

● Move the component changeover table into the machine or install the right-hand component table with the
assistance of a 2nd strong person.
● Set up the reassembled component table properly in accordance with the "set-up".
The component table must always be completely equipped (see above DANGER note).
● If applicable, move the wafflepack changer back into the machine.
● Remove all of the components and tools lying in the machine.
● Plug in the connectors of the WPC or the component changeover table in the correct sequence -> First
the interface cable, then the power cable.

After exchanging the cable "coplanarity terminal panel" and after every other step involving its wiring, the
laser shut-off unit must be checked explicitly, as described here.
DANGER O O O
As with all the retrofitting, the following jobs are to be performed only by the Siemens service engineer or
by a Siemens-trained service engineer of the customer.
Before doing this work the service engineer in question must receive instruction from a laser protec-
tion officer.
The laser shutoff is only to be checked indirectly , i.e., with the help of the test connector.
To check the sensor cable it is to disconnected directly at the coplanarity option processing unit and the test
connector is to plug in on in the processing unit on the where the sensor cable is removed from. The laser its-
elf (coplanarity sensor) is therefore not running during this check.
The laser shut-off must be checked during all subsequently named interruptions in protection, once with the
key-operated switch locked ("0") and once with the key-operated switch in the service position ("I").
12.6.15.1Interruptions in Protection which must be Checked
Perform the following checks as described in detail below under “Steps in the Check” Section 12.6.15.2 bes-
chrieben:
- Open and close each of the 4 protective covers/hoods:
Input, output, protectve hoods (left and right).
- Actuate and release each of the 3 EMERGENCY OFF buttons: input, output and WPC
- Electrically isolate and connect the 2 component tables from/to the machine.
Sequence while pulling the plug-in connectors -> see WARNING below.
