3 Press the emergency stop switch on the back of the unit to turn OFF the servo.
Since this work is performed from the back of the unit, press turn OFF the emergency stop
switch on the back of the unit to turn OFF the servo in order to prevent other workers unaware
of working from operating the unit on the front side mistakenly.
[Axis center adjuting procedure]
1 Visually check that axis center of the plunger
matches.
If the axis center matches, it is unnecessary to adjust,
however, be sure to re-tighten the mounting bracket.
If the axis center does not match, adjust the axis cen-
ter according to the following procedure.
2 Perform adjustment of axis centers of the
mechanical valve and plunger.
1. Loosen the cap screws (2 pcs, C3 x 6)
on the mounting bracket for plunger.
2. Move the bracket back and forth to
match the axis centers of the me-
chanical valve and the plunger.
3. While matching the axis center in
height direction, fasten the cap screws
(2 pcs, C3 x 6) to fix the bracket.

[Gap adjusting procedure]
1 Adjust the gap between the end of the re-
tracted plunger and the end of the projected
mechanical valve to 1.5 mm.
1. Loosen the cap screws (4 pcs, C3 x 5).
2. Adjust the gap between the end of the
retracted plunger and the end of the
projected mechanical valve to 1.5 mm
using a thickness gauge.
The mechanical valve and the plunger
head should be parallel to each other.
3. While matching the axis center in
height direction, fasten the cap screws
(4 pcs, C3 x 5) to fix the plunger.

[Procedure]
1 Loosen the bolts fastening the mounting
bracket for the plunger return sensor.
2 Adjust the LED extinguishing position of the
plunger return sensor (Upper/Lower).
1. Press in the mechanical valve.
2. Pull out the plunger by hand, and
pinch a thickness gauge of t=1.0 mm
between the plunger and mechanical
valve.
3. Move the bracket to adjust the sensor
position so that the LED for the
plunger return sensor extinguishes in
this state.
3 Fasten the bolts for the mounting bracket to fix the plunger return sensor.
