3.1.2 Connecting sensors
£ Check whether the required sensors are connected
before turning on the unit [27].
The minimum required sensors:
– Label sensor (installation location: dispensing edge)
– Product sensor (installation location: conveyor belt)
Additional optional sensors:
– Rotary encoder (required for speed adaption)
– External roll diameter sensor (provides advance
warning of the end of a label roll)
– Alternative label sensor; for example, capacitive
sensor, used to detect transparent labels.
Sensors for internal OD-control:
– Requires cabel kit A9767. For two unwinders, two
cable kits are required.
£ Connect 2 cables for each unwinder to the unwinder
[28A] and to the rear side [27F-I] of the machine.
You can find further information regarding suit-
able sensor types, pin assignments, and so on
in the service manual.
