Modular Conveyor Replacing the Limit Switch for the End Position Width Adjustment System
134 Service Manual SIPLACE D4
Removal/Installation
NOTE:
The limit switches are preassembled
and include cables.
X However, if the limit switch itself is
faulty, the wiring can be unsoldered/
soldered right at the switch in
question.
X Unsolder the connection wires on the faulty
limit switch (1).
X Loosen and remove the two screws (2)
fastening the defective limit switch.

check, this cable must be unthreaded
as far as the conversion board of the
assembly tray and unplugged there.
This might be somewhat complicated
depending on the routing of cables
inside the machine base.

Se
rvice regarding this
work.
Checking t
he position of the limit switch:
