Connecting sensors
 Before switching on the machine, check to ensure all
required sensors are securely connected [41].
More extensive information about suitable
sensor types, pin assignment, etc. may be found
in the Assembly/Service manual.
Minimum required sensors
• Label sensor [41A]
(assembly location: dispensing edge)
• Product sensor [41B]
(assembly location: assembly line)
• Linear dancer lever sensor [41D][42]
Optional additional sensors
• Rotary encoder (for automatic speed adaptation)
[41C].
• Alternative label sensor [41D]
• Sensors for internal OD detection:
The sensors for OD detection are integrated into
the material dispenser and must be connected with
the optionally available cables.
– Dispenser 1: connections [41E+F]
– Dispenser 2: connections [41G+H]
WARNING!
This unit operates at mains voltage!
Contacting electrically live components can
cause lethal electrical shocks and burns.
 The machine must only be connected
with other machines if they meet the
requirements of a SELV circuit (Safety
Extra-Low Voltage circuit) in accordance
with EN 60950.
