Check whether the strain relief devices for the new PCB assembly still fit, as shown below in
Fig. 2.6.4 and Fig. 2.6.5:
– on the 3 ribbon cables of the adjustment units (SLQconnectors) and
– on the 16-pin ribbon cable for vacuum (SLQconnectors)

1. Modular head PCB, complete, installed
2. Strain relief device on PCB connectors
3. NEW connector = large nose on the entire side = matching
4. OLD connector = small nose connector must be exchanged.
5. 2 ribbon cables, 40-pin, and 1 ribbon cable, 26-pin *)
*) These cables are always exchanged on HS-50 and on S-23, S-25 HM and F5 HM because the
cable run has been changed (see Fig. 2.6.7 to Fig. 2.6.11).

1. Strain relief device, suitable for the connectors of the modular head PCB
2. Big nose on the connector
Å If the strain relief devices on the 10-pin and 16-pin ribbon cable connectors match, proceed to
the next section.
Å If the strain relief bars do NOT match, mount the new connectors and strain relief devices from
the separate service package (see Section 2.4.4) as follows:
Å With an indelible marker, mark PIN 1 on each of the DERYHPHQWLRQHG4 ribbon cables.
Å Use the ribbon cable pliers from the separate service package to remove the DERYHPHQ
WLRQHG4 ribbon cable connectors as close as possible behind the connector.
Å Use the crimping tool for ribbon cable and the new connectors from the separate service
package:
- For each placement head: 3 units 10-pin insulation displacement connectors made
by Bancon, Order no. 050-010-435 A
- For each placement head: 1 unit 16-pin insulation displacement connector made by
Bancon, Order no. 050-016-435 A
Å Attach these connectors to the ribbon cables in the correct rotational position/PIN alloca-
tion.

Å Mount the strain relief device (see separate service package) on the connectors:
- for 10-pin connector, Order no. 050-000-010
- for 16-pin connector, Order no. 050-000-016
Å As the next step, check the PIN allocation.

Å To be on the safe side, check the PINs of the connectors of all modular head PCBs
(S-23/S-25HM, F5 HM, HS-50) by comparing each with the jack connector to be connected to
it.
-> Upon receipt, the pertinent PINs must have already been removed.
In the exceptional case that this is not the case, remove with pertinent PIN with the ESD ob-
lique-nosed cutting pliers.
Å Proceed to lay the cables and to plug in the connectors, as described in Section 2.6.5.
