8.3 Input signals

This machine (dispenser) is provided with photo coupled inputs for:

ythe product sensor signal

yan inhibit signal for inhibiting labelling

ya signal from an OD control which shows the end of the material roll.

ya signal from an automatic product speed follower

ythe EP applicator signals from the HOME and END switches

yan unused input for future extensions or customer specific software (used for loop control in the 720)

The inputs are galvanically separated through photo couplers to connect to PNP or NPN outputs. The wiring and the connection of the signal plug is shown otherwise. The input voltage across the inputs must be in the range of 15 V to 30 V to switch active.
