Instruction manual FA13

Mounting speed sensors with difference-Hall
principle, type FAHxx
Mount the sensor according to the following instructions:
►
Prerequisite:
The system is switched off.
►
Prerequisite:
The mounting hole and the scanning object have been
checked before mounting the sensor.
A. Remove the protective cap from the measurement area and the thread
protection.
B. Screw the sensor carefully into the designated mounting hole and po-
sition the sensor exactly to the scanning object.
C. Check the recommended distance to the scanning object (see Section
Technical Data).
A too close scanning distance may lead to signal distortion,
signal loss or may even damage the sensor and the scanning
object.
Thus, maintain the recommended scanning distance.
D. If the scanning object is not visible: screw the speed sensor clockwise
to the end stop (until the sensor touches the scanning object).
NO-
TICE! Attention: The scanning object must stand still!!!
Now screw
the sensor anti-clockwise according to its thread type to get the cor-
rect scanning distance (e. g. with thread type M18x1 one rotation cor-
relates with 1 mm, with thread type M18x1.5 one rotation correlates
with 1.5 mm, etc.). When mounting the sensor in a hole without a
thread, the distance to the scanning object can be adjusted by the nut
for mounting and the counter nut.
E. The mounting of this sensor type is
direction sensitive
. Note the po-
sition of the marking. Now screw the sensor clockwise or anti-clock-
wise (use the shortest screw path) that the marking of the sensor is
aligned in direction of rotation of the scanning object (see next Fig.,
Pos. B).
