With motorized unwinders the signals for end of reel and diminishing reel can be detected at the same
time only if the unwinder is connected via CAN bus (X18). Detection of these web signals is effected
automatically.
If, however, external sensors for detecting end of reel (at X3) and diminishing reel (at X2) are to be
used at the same time for a motorized unwinder of the winder system at the CAN bus this plug of X17
must be removed from X3. The printer signal can then not be interrogated any longer.
Additionally the jumper from pin 7 to pin 8 on X27 must be removed since otherwise end of reel would
be indicated as a printer error.
For the appropriate pin assignment of the connections, refer to the section 5
or the separate wiring diagram.
All plugs are secured with coupling rings. Do not tilt the coupling rings when
screwing it onto the socket because this could damage the thread or render it
unusable. Screw the plugs in completely in order to ensure safe long-term
contact.
See chapter 5 for the assignment of connectors X10 and X19 (if available).
