2.3 Step by step installation of the VM 3.12 Sensor
2.3.1 Preparation of Stator Surface
After identifying and marking the locations where the sensor should be installed, clean the stator surface to
remove all dust deposits. This step must not be neglected as sensor adherence depends on the preparation
of the surface.
1. Clean the stator surface with a clean dry cloth.
2. Run fine sandpaper on the stator surface, straight along the laminations, just to remove surface dirt as
preparation for glueing. Make sure only non-metallic paper is used.
3. After sanding, clean the stator surface again with a dry cloth.
2.3.2 Glueing the VM 3.12 Sensor
Integral cable
1. If needed, clean the back of the sensor with a clean dry
cloth.
2. Apply glue on the back surface of the sensor. Spread glue
to a thin and even coat, which will not run down when the
sensor is pressed against the stator.
3. Apply the catalyst over the glue on the sensor.
4. Position sensor on the clean surface of the stator. The
sensor must face the plane area of the rotor poles, which
usually starts after the second ventilation hole.
5. Pivot sensor slightly to blend the catalyst into the glue and
to spread the mix evenly, and then reposition vertically.
Hold in a straight, upright position for 60 seconds.
6. Temporarily tape the flat cable to the stator so that it does
not get pulled inadvertently.

You will need to glue the integral flat cable to the stator, but only after having completed the installation of the
extension triaxial cable. Finally, you must also apply a fine bead of silicone around the sensor edges and over
the integral cable to prevent damage from dirt and particles, and to protect the sensor edges from deterio-
ration.
Caution
•
Sensors must be glued on stator core laminations, and NEVER ON THE WEDGES.
•
Handle the glue with care to avoid skin contact.
•
The glue bonds and sets quickly. All preparation must be completed before applying the glue.
