FITTING OF SENSORS
Fitting of Sensors
Prepare the sensors and screw the mounting piece to the
sensor.
Screw the sensing head into the existing hole of the bar and
position it in the middle of the hole of the mounting piece. It
is necessary to do it in this way to be able to make a read-
justment.

133N1
FITTING OF SENSORS
At least: the measuring slit should be in the range of the press
roller. (Picture)
If this is not so, the metal bar with with screwed on sensor
should be slided. This should be done by the mill mechan-
ics.

CABLING OF THE SECTION ELECTRONIC (SE)
Labeling of SE-Board
The labelling is to be done by the fitter. As soon as the Q-
Boards are placed the attached stickers must be fixed.
This marking serves for a correct cabling and helps in case
of exchange.
Blue: SE-Board number
Yellow: first and last rotor number on each side.
SE Address
Set the right address on the switch of the SE. Address sticker
is on the SE case.

CABLING OF THE SECTION ELECTRONIC (SE)
Sensor Cables
On each machine side:
6 cables, length 3m (SCU side, longest way to Q-Board)
6 cables, length 2m (shorter way to Q-Board)
Cable from the sensor to the inside of the machine. Use the
support (different types available).
Inside (view of the backside of the rotor)
For sensor cable layings an orderly laying is necessary to
avoid unnecessary kops. Use cable channels.
Labling of sensor cable (hanging end!!), when the cable is
plugged into the sensor and led to the inside.
Use the Rotor number as a help!!!
