4.2 Description
Operating principle
The FPS sensor system consists of a magnetic field-sensitive
sensor and electronic processor. A permanent magnet is attached
to the base jaw of the gripper, which moves past the sensor in
parallel. The output voltage of the sensor changes with the
position of the permanent magnet. This voltage is amplified in
the electronic processor and divided into five reference points.
The reference points are saved using pushbuttons or via the
control unit. When a reference point is reached, the
corresponding digital output is switched on and the previous
output is switched off. Only one digital output is active at a time.
Instructions for use
Observe the following when using the FPS sensor system:
l
Avoid using the sensor in the immediate vicinity of strong
magnetic fields or temporarily approaching or touching the
sensor or the magnet of larger ferromagnetic materials. There
is no impact due to these kinds of materials being gripped, as
the distance to the sensor is sufficiently large (>10 – 20 mm).
l
Avoid contamination of the sensor or the magnet due to
ferromagnetic chips and dust.
l
Adjust the sensor at operating temperature to achieve the
accuracy specified in the catalog.
l
Ground the electronic processor to the ground connection on
the bottom to avoid small interference pulses on the ground
line. In the event of major faults, determine and eliminate
the cause.
l
For increased precision, calibrate the electronic processor at
regular intervals.
