Error indication
Problem Possible
causes
Investigation method
Countermeasure
The operation is
unstable.
(chattering)
The hysteresis is
small and is
affected by the
fluctuations in the
original pressure,
etc.
Check the set value (hysteresis).
Check the settings
Incorrect wiring/
broken lead wire
(1) Check the power supply wiring.
(2) Check if there is bending stress
applied to any part of the lead wire.
(bending radius, tensile force to the
lead wire)
(1) Check and correct the wiring.
(2) Correct the wiring.
(Reduce the tensile force or
increase the bending radius.)
