For the ALS 104 to be used with automatic speed ad-
justment, an rotary encoder must be connected. The
rotary encoder communicates the conveyor belt speed
to the label dispenser.
Requirements for rotary encoder:
– Permitted sensor types: Push-Pull, PNP or NPN
– Preset: PNP
– Required specification data for rotary encoder:
Nominal voltage
Output current
Resolution
Rise time
Decay time
Frequency
Pulse/pause ratio
