Adjustment of the
switching points
Ø Press the "Teach" button (4) for 2 seconds.
After 2 seconds, LED 1 (3) flashes.
Ø Move the gripper to position 1 (e.g. "Open").
Ø Briefly press the "Teach" button (4).
LED 1 (3) lights up and LED 2 (5) flashes.
Ø Put the gripper in position 2.
LED 1 (3) should go out as soon as switching point 1 is left.
Ø Briefly press the "Teach" button (4).
LED 2 (5) lights up.
The switching points are set.
Adjusting the
hysteresis
The hysteresis to both switching points will be adjusted automatic-
ally corresponding to the characteristics of the magnetic field.
The user can set the switching and trigging points of each position
a little bit closer than for the automatic mode. The trigging point is
closer to the switching point. At the same time the susceptibility to
trouble and damage increases. In the mode of the lowest hyster-
esis, an error signal (such as jitter or untimely switch off) can be
avoided, if the sensor is protected against all types of disturbances
(i.e. by shielding). Frequent types of disturbances are change in
temperature and electro-magnetic influences.
Within the closest fine-teach mode, SCHUNK cannot guarantee
EMC-compatibility any more.
The hysteresis adjustment is used for the manual adjustment of
the switching points (if necessary).
In case that the hysteresis automatically determined by the sensor
should be too high or too low after “the adjustment of the switch-
ing points”, you may correct the value as follows.
The sensor avoids a too small hysteresis during hysteresis adjust-
ment.
