The hysteresis to both switching points will be adjusted automati-
cally 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 hysteresis,
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 tempera-
ture 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 switching
points”, you may correct the value as follows.
The sensor avoids a too small hysteresis during hysteresis adjustment.
The lowest securely detec
table difference in stroke is ≤10 % of the
nominal stroke.
1 Press the Teach-button (4) for 5 seconds.
LED 1 (3) will flash up after 2 seconds.
LED 1 will stop after 5 seconds.
2 Release the Teach-button.
3 Move the gripper to the "switch-off point for switching point
1" position.
4 Press the Teach-Button (4) briefly.LED 1 (3) will light up twice.
5 Move the gripper to the "switch-off point for switching point
2" position.
6 Press the Teach-Button (4) briefly.
LED 2 (5) will light up twice.
The mounting of the sensor MMS-P is completed.
