23.4 WIRING
This section describes the wiring and cable connections specific to the blending dispenser.
Additional components used are:
−
a second Integrated Stack Controller located in the head
−
a second Multiplexer located in the hydraulic cabinet
−
a second Barrier located in the head
−
an Auxiliary Power Module
The Multiplexer Board for a particular side is located on the right.
Compared to the wiring in a conventional dispenser, the
Auxiliary Power Module is wired
in a similar way, whereas the Multiplexer Board is slightly different.
23.5 Stack Controllers
Each Integrated Stack Controller has valve sockets marked P28-P22 from left.
