SAFETY INSTRUCTIONS
Operational Notes
The installation of the equipment should only be performed
by qualified personnel being familiar with all safety checks,
installation and service guidelines.
Improper operation of the equipment could cause hazards.
In accordance with 98 / 37 / EEC, 2006 / 95 / EC, 2004 / 108 /
EC. Do not open any covers (cooling, fire protection, contami-
nation, spark interference etc.)
Electronic components and assemblies (printed circuit
boards) are endangered by electrostatic charges! Be-
ware of touching the soldered connectors, pin contacts be-
fore they have been discharged statically. Hold the units at
the periphery only.
Upgrade works must be carried out with switched off
mains switch only. Failing to observe this warning may
lead to death or severe injuries!
This yarn clearer system must be connected to the power
supply only after installation of all front panels, plug-in boards
and provided covers, in particular of the central unit.
Connect the supply input of the Q-UNIT 3N1 to a 24Vdc SELV
supply, that is switched off if the machine is switched off, or
if the emergency button is pushed.
Make the earth connections.
Unit specifications see last page.

4K
LAN to Q-Board
The power supply must be installed by an electrician
Cabling SCU Front
1. Drill 4 holes Ø 5mm and deburr.
2. Install the power supply as shown. Mounting parts and
cable ties are provided
3. Fix the power input and power output cables with the ca-
ble ties to the power supply, as shown.
4. Make sure that the cables are tied at the cable mantle and
not at the wires.

PREPARATION OF CABLING
Black: Power supply from machine or external
White: Power supply for SCU: 24V (30W), only use one
of the outputs!!
Power: To be connected with an external power supply or
have it connected to the machine electronics by an electri-
cian. Power from Schlafhorst’s control unit.

PREPARATION OF CABLING
LAN to Q-Board
Yellow: LAN to Q- Board
Red: 4K cable to 4K card at Schlafhorst Informator
Blue: Ground: to housing (or somewhere else with an as-
sured ground)
White: power cable for power supply, front side as installed.
Black: power supply from machine or external.
Remove the cover:
Use the cable track to fit the cable before you feed it into the
cable channel (above). This cable goes directly to the first SE
Board (long LAN cable)
Connect the 4K cable to the interface in
the Informator.

Connection 4K to SCU
Red: 4K
4K cable to 4K card (inside of the Informator)
The card is written down.

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 (Pic-
ture 1) and position it in the middle of the hole of the mount-
ing piece (Picture 2). It is necessary to do it in this way to be
able to make a readjustment.

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 mechanics.
To do this the adjusting parts for the sensor should be used,
if available.

Connections to SAG
Red: Q-Stop cable, each for one side (12 rotors)
The SAG board requires an Interface print. It can be simply
plugged on.

CABLING OF THE SECTION ELECTRONIC (SE)
Power Supply for SE
The power supply must be installed separately. The conduc-
tor is looped in in series. The main conductor can be pow-
ered by Schlafhorst or externally. A first cable is laid from this
power supply up to the first empty shaft door. There it is con-
nected to the serial line, which must be laid into the shafts.
The transformer must be screwed onto the empty shaft cover
(see drawing page 10).
