Problem
Possible cause
Countermeasure
1
The switch output does not
turn OFF.
The Indicator light does not
turn OFF.
Malfunction due to
magnetic field
Keep the actuator 40 mm or more away from
adjacent actuators to avoid the influence of
magnetic fields. Install a magnetic shielding plate
between the actuators.
If a magnetic field source is present near the
actuator (electric welding machine conductor,
motor, strong magnet etc.), use a magnetic
shielding plate between the magnetic field source
and the actuator.
Improper setting
(mounting) position
(Narrow angle)
When the product operation range is larger than
the piston stroke range, position the product
away from the centre of the operation range.
2
The switch output does not
turn OFF.
The Indicator light does not
turn ON.
Product failure
Replace the Product.
3
The switch output does not
turn ON.
The Indicator light does not
turn OFF.
Product failure
Replace the Product.
4
The switch output does not
turn ON.
The Indicator light does not
turn ON.
Power supply failure
Supply the specified power supply voltage (when
the power supply voltage is zero or very low).
Incorrect wiring
Check and correct the wiring.
Improper setting
(mounting) position
If the product is operating near the limit of the
operating range, position the product to the
centre of the operating range.
Displacement from the
set position
If the mounting bracket or mounting screws are
loose, tighten them using the appropriate
tightening torque at the correct position.
Displacement of the
actuator stopping
position
When the stop position of the actuator piston is
inconsistent, take measures to stabilize the
position.
Reduction in magnetic
detection force
(demagnetization)
Keep the actuator 40 mm or more away from
adjacent actuators to avoid the influence of
magnetic fields. Install a magnetic shielding plate
between the actuators.
If a magnetic field source is present near the
actuator (electric welding machine conductor or
strong magnet), use a magnetic shielding plate
between the magnetic field source and the
actuator.
