Problem
Possible cause
Investigation method
Countermeasure
Abnormal power
source
Check the source voltage.
(Zero or very low)
Set the source voltage to
specified voltage.
(Refer to "Specifications (power
voltage and load voltage)" on
page
19
.)
Wiring failure
Voltage applied to switch
(load voltage).
Correct wiring.
(Refer to "Circuit diagram" on
page
14
.)
Incorrect setting
(mounting) position
Check if detection is made close
to the operation range limit.
Correct the position.
(Center of operation range)
Set position
displacement
Loose set bracket or set screw.
Fix at the right position with right
torque.
Tightening torque: 0.8 to 1.4 Nm
Stop position
displacement of
the piston
Check if the stroke stop position
is Inconsistent.
Stabilize stop position.
(Correction of displacement /
cushion)
Presence of magnetic field
generating source around the
cylinder.
(Electric welding machine
conductor / Strong magnet)
Use the shield between
magnetic field generating source
and cylinder.
Influence of magnetic field of
adjacent cylinder (20 mm or
less).
Keeps cylinder away (40 mm or
more).
Use magnetic shielding.
Decrease of
Detected magnetic
field
(demagnetization)
Presence of magnetic material
(chip) piled up on the cylinder.
Remove piled up magnetic
material.

OFF
Display stays
OFF
Lead wire
disconnected
Presence of repeated bending
stress to one point of the lead
wire.
(Bend radius / Tensile force to
lead wire)
Correct wiring.
(Correct tensile force / increase
bend radius)
