Problem
Possible cause
Investigation method
Countermeasure
15
Operation is
unstable
(chattering).
Effect of line
pressure
fluctuation
because
hysteresis is too
narrow or
response time is
too short
(1) Check the set pressure values
(hysteresis)
(2) Check the response time.
(1) Widen the hysteresis.
(2) Change the response
time setting.
Incorrect wiring/
broken lead wire
(1) Check the power supply wiring.
(2) Check if there is bending stress
applied to any parts of the lead
wire.
(Bending radius and tensile force
applied to the lead wire)
(1) Correct the wiring and/or
load resistance
(2) Correct the wiring.
(Reduce the tensile force
or increase the bending
radius.)
Product failure
Replace the product.
