3.1ELECTRICAL CONNECTIONS
3.1.2Connecting sensors
Check whether the required sensors are connected before turning on the unit [30].
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 outer diameter checking sensor (provides advance warning of the end of a label roll)
–Alternative label sensor; for example, capacitive sensor, used to detect transparent labels.
You can find further information regarding suitable sensor types, pin assignments, and so on in the service manual.
