4.2. Wiring the components on the flexible circuit
q Important: it is essential that the component mounting direction be respected.
1. Position the strut (1.5mm) between the 4 pin photo switch and weld the syringe head detection
photo switch flattening it against the flat cable.
Important: use a silicone between the optical switch and the flat ribbon cable. The silicon should not be
over the soldering area.
Important: verify there is no resistor continuity between the optical switch axis stop and the flat ribbon
cable.
2. Weld the disengaging switch flattening it against the flat cable.(at roughly 1.5 mm).
3. Cut the part of the flat cable corresponding to the back pressure microswitch of version A2 (see
cutting zone in the diagram below).
Weld the disengaging microswitch without flattening it against the flat cable (at roughly 1.5 mm).
4. Weld the force sensor wires
Important: when disassembling a force sensor, take care not to damage the welding pellets.
5. Pass the flat cable in the force sensor oblong.
Important: When disassembling the flexible circuit from the driving block holder, take care not
to detach or damage the holder protection square. The purposeof this square is to hold the flexible
circuit
correctly inplace and avoid short-circuits with the holder.
