Mounting the speed sensor
Mounting speed sensors with inductive-magnetic
principle, type FAJxx
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
align the sensor exactly to the scanning object.
➩
The mounting of the sensor is
direction independent
.
C. Check the recommended distance to the scanning object.
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.
➩
The cover ratio of the measuring area and scanning object should
amount at least to 2:3.
E. With modules > m2 the scanning distance may need to be adapted to
get a valid output signal (see the following diagram).
