Problem Possible cause Investigation method Countermeasure
Wrong pressure
setting
(1) Check the set pressure.
(2) Check the settings of the
operation mode, hysteresis and
output style.
(Hysteresis mode/window
comparator mode, normal
output/reversed output)
(1) Reset the pressure
setting.
(2) Reset the setting of
function.
1
•
Output remains
on.
Indication light
remains on.
•
Output remains
off.
Indication light
remains off.
Product failure Replace the product.
Incorrect wiring
Check the wiring of the output line.
Check if the load is connected
directly to DC(+) or DC(-).
Correct the wiring.
2
Output remains
on.
Indication light
works correctly.
Product failure Replace the product.
Incorrect wiring
Check the wiring of the output line.
Check if the load is connected
directly to DC(+) or DC(-).
Correct the wiring.
Unsuitable model
selection
Check if PNP is used even though
NPN should have been selected, or
the other way around.
Review the selected model
(output type).
Lead wire
breakage
Check if there is bending stress
applied to any parts of the lead wire.
(Bending radius and tensile force
applied to the lead wire) Correct the wiring
conditions. (Adjust the
tensile force and widen the
bending radius.)
3
Output remains
off.
Indication light
works correctly.
Product failure Replace the product.
Incorrect wiring
Check the wiring.
Check if the brown and blue wires
are connected to DC(+) and DC(-)
respectively, and if the output line is
about to come off (contact failure).
Correct the wiring.
Wrong setting
(1) Check the set pressure.
(2) Check if the hysteresis range is
too narrow.
(3) Check the response time set as
initial setting.
Check if the response time is too
short.
(1) Reset the pressure
setting.
(2) Widen the hysteresis.
(3) Reset the setting of
function.
4
Switch output
generates
chattering.
Product failure Replace the product.
5
Slow switch
output response Incorrect pressure
setting
Check the pressure setting.
Check if the detected pressure and
the set pressure value have the
same value or are too close.
Reset the pressure setting.
Set up the pressure setting
value so it is not too close
to the detected pressure
value.
