4 Assembly and settings
NOTE
The assembly instructions in this chapter are generally
applicable.
Module-specific assembly instructions for the sensor can be
found in the Assembly and Operating Manual for the module,
which can be downloaded at schunk.com
4.1 Mechanical connection
CAUTION
Property damage due to incorrect bending radius!
The product may get damaged if the cable's bending radius is
less than the minimum.
lStatic: 10 times the cable diameter.
lDynamic: 15 times the cable diameter.
CAUTION
Risk of damage to the sensor during assembly!
lObserve the maximal tightening torque.
Ferromagnetic components change the sensor's switching
positions, e.g. adapter plate made of construction steel. For
ferromagnetic adapter plates:
lFirst, install the module on the adapter plate.
lThen adjust the switching position of the sensor.
NOTE
lDo not use the sensor as a safety component.
lDo not pull on the cable of the sensor.
lSecure the cable and connection plug so that they are not
taught and cannot move during operation.
lDo not exceed the permitted bending radius of the cable.
lDo not allow the sensor to come into contact with hard
objects and chemicals (e.g., nitric acid, chromic acid and
sulfuric acid).
The sensor is an electronic component that can be sensitive to
high-frequency interference or electromagnetic fields.
lCheck whether there is sufficient distance between the sensor
and sources of interference and their supply cables.

Mechanical connection
1. Turn the sensor (1) into the groove (2),
Or:Push the sensor (1) into the groove (2) until it reaches the
clamping stop (3).
2. Secure the sensor (1) using the set-screw.
ðObserve the maximum tightening torque of 10Ncm.
3. Connect the sensor (1) and fasten the cable.
4. Secure the electronics with cable connectors to relieve the stress
on the cable.
ð Use the ribs on the electronics to fasten the cable.

4.4 Adjusting the sensor
4.4.1 Setting switching points in teach mode
NOTE
The difference between the teach and operating temperatures
must not exceed 30 K.
NOTE
Once the switching points have been set, the environment of the
sensor may no longer be changed.
1. Move module to Switch-off point for switching point 1 position.
2. Press the "Teach" button (2) for 2s.
ðLED 1 (1) flashes after 2s.
3. Briefly press the "Teach" button (2).
ðLED 1 (1) lights up once the switching point has been
taught.
ðLED 2 (3) flashes.
4. Move module to Switch-off point for switching point 2
position.
ðLED 1 (1) goes out as soon as the module leaves Switch-off
point for switching point 1.
ðLED 2 (3) flashes.
5. Briefly press the "Teach" button (2).
ðLED 2 (3) lights up once the switching point has been
taught.
4.4.2 Setting the hysteresis
The switch-off point of the end position can be manually
adjusted by adjusting the hysteresis.
A minimum and maximum hysteresis is defined based on the
magnetic field. This defines the distance between the switch-on
and switch-off point. The sensor prevents a hysteresis that is too
low when the hysteresis is adjusted. If the switch-off point is
taught too far away from the switch-on point, the switch-off
position close to the switch-on point is automatically used. The
switch-off point must then be taught closer to the switch-on
point.

Troubleshooting
12 01.00 | MMS-P22 / MMSK-P22 | Assembly and Operating Manual | en | 1566688
5 Troubleshooting
5.1 Sensor not operating
1. Check whether the sensor cable is broken.
2. Check whether the voltage at the sensor is within the
permitted range, }3 [/7].
3. Check whether the LED lights up at the position to be sensed
and that the sensor is operating.
NOTE
If the LED does not light up or the sensor is not operating,
contact SCHUNK Service.
5.2 Sensor is operating, but not as desired
Possible cause Sources of interference Corrective action
The sensor is interfered with or
influenced by external
magnetic or soft magnetic
materials (Fe).
Motors (coils) Increase the distance
between the sensor and
sources of interference
(until the sensor operates
correctly).
Relays
Linear motors
Electrical welding
Magnetized workpieces
(workpieces made of iron (Fe)
or similar materials)
Use finger attachments
made of aluminum.
Magnetized components and
tools made of iron (adapter
plates made, screws or
hexagon socket keys, etc.)
Use components containing
aluminum. V4A screws are
recommended.
The sensor is influenced by a
different sensor.
Same or similar product Increase the distance
between the sensors to at
least 2mm.
The sensor is affected by
deposits of magnetic chips in
the vicinity (in the air gap).
Liquids with magnetic chips or
the like.
Regularly clean the
immediate environment of
the sensor. (The higher the
exposure to such fluids, the
more often it needs to be
cleaned.)
The sensor is affected by the
directly adjacent module.
Built-in magnets in the piston
of the adjacent module
Increase the distance to the
adjacent module to at least
10mm.
NOTE
If these steps do not eliminate the problem, contact SCHUNK
Service for troubleshooting.
