Technical data: Sensor installation position, analog output adjustment method
When analog output type hand is installed
Analog output voltage adjustment method
The analog output voltage is adjusted so the master jaw
(jaw) full stroke is 5 V when open and 1 V when closed.
However, the voltage may slightly vary due to the working
environment (effected by magnetic bodies in the area), so
adjust finely with the following procedures.
(1) Connect the brown wire to the (+) side of the 24 VDC
stabilized power, and the blue and orange wires to the
(-) side.
(2) Connect the black wire to the (+) side of the voltmeter
and the blue wire to the (-) side of the voltmeter.
(3) Move the master jaw, and read the voltage value when
open and closed.
(4) If the difference of the voltage in (3) is 4 V or less, turn
the span adjustment trimmer slightly clockwise. If more
than 4 V, move the trimmer slightly counterclockwise.
(5) Move the master jaw again, and read voltage when
open and closed. Adjust the zero point adjustment trim-
mer so the reading is 5 V when using the open state
as a reference, and 1 V when using the closed state
as a reference.
(6) Repeat steps (3), (4) and (5) several times, and ad-
just finely.

Sensor installation position adjustment method
Before shipment, the sensor is installed at the center of
the stroke for both jaws on the master jaw. Follow the fol-
lowing procedures to adjust the position if the sensor in-
stallation position has been changed or the hand has been
replaced.
(1) With the sensor removed, move the sensor installation
position indicator light adjustment trimmer so the sen-
sor installation position indicator light (yellow LED)
turns ON. Set the trimmer to the center of the interval
at which the yellow LED turns ON. (This is adjusted
before the product is shipped, so adjust even if the
trimmer has been moved inadvertently.)
(2) Move the hand master jaw (jaw) to the center of the
stroke.
(3) Install the sensor on the hand. Fix the sensor where
the following operations are satisfied. The sensor tight-
ening torque is 0.1 to 0.2 N·m. Install the sensor case
so the sensor installation screw (M2.5 nonrotating set
screw) faces the master jaw (jaw).
1. Sensor installation position
Fix at the center of the second lighting interval includ-
ing where the sensor installation position indicator turns
on at (1). (The second lighting is a short interval such
as roughly 1mm when the piston stroke is converted.)
