Trouble
No.
Trouble
Possible cause
Investigation to find possible
cause
Countermeasure
Power supply
failure
Power supply voltage (zero or
extremely low)
Adjust power supply voltage to a
given value.
(Refer to "Power supply voltage
or Load voltage" in Specifications
on page 17.)
Incorrect wiring
Voltage (load) applied to the Auto
switch
Correct wiring.
(Refer to "Internal circuit" on
page 12.)
Improper setting
(mounting)
position
Detection close to the limit of
operating range
Move the Auto switch to proper
position (near the center of the
switch operating angle).
Displacement
from set position
Looseness of the switch unit or
switch mounting screw
Fix to proper position at
appropriate torque. (Tightening
torque: 0.05 to 0.15 Nm)
Displacement of
the actuator
stopping angle
Deviation of the actuator
stopping angle (position)
Stabilize stop position.
The presence of magnetic filed
source near the actuator (electric
welding machine conductor and
strong magnet, etc.)
Place a magnetic shield plate
between magnetic filed source
and the actuator.
The effect of magnetic field
generated by adjacent actuator
(placed within 20 mm)
Separate the actuator (by 40 mm
or more). Place a magnetic
shield plate.
Lowering of
magnetic force
for detection
(demagnetization)
The presence of deposit of
magnetic material (cutting chip)
on the actuator
Remove the magnetic deposit.
4
The switch
output doesn’t
turn on. The
operation LED
doesn’t light up.
Breakage of
lead wire
The presence of repeated
bending stress to a part of lead
wire
(bending radius, tensile force to
the lead wire)
Correct wiring.
(Adjust tensile force and enlarge
bending radius.)
