response.
Possible cause
(1) Check the set pressure value.
Incorrect pressure
(2) Check the settings of the
setting
hysteresis and output type.
Product failure
Incorrect wiring Check the wiring of the output.
Product failure
Incorrect wiring Check the wiring of the output.
Check if there is bending stress
applied to any parts of the lead wire.
Broken lead wire
(Bending radius and tensile force
applied).
Product failure
Check the wiring.
Incorrect wiring Check if the output wiring is loose
(contact failure).
(1) Check the pressure settings.
Incorrect setting (2) Check if the hysteresis range is
too narrow.
Product failure
Check the pressure settings.
Incorrect pressure Check if the detected pressure and
setting the set pressure values are the same
or are too close.

Countermeasure
(1) Reset the pressure
settings.
(2) Reset the function
settings.
Replace the product.
Correct the wiring.

Replace the product.
Correct the wiring.
(1) Reset the pressure
settings.
(2) Increase the hysteresis.
Replace the product.
Adjust the set pressure
value.
Ensure the set pressure
value is not too close to the
detected pressure value.
