Reference
No.
Problem Possible cause Investigation method Countermeasure
Incorrect wiring
(1) Check the connection at FUNC
terminal.
Check the power supply wiring.
(2) Check the length of lead wire.
(1) Correct the wiring.
(2) The maximum
transmitting distance of
the copy function is 4 m.
Shorten the lead wire to
4 m or less.
Improper model
The models of the master Pressure
switch and the slave Pressure switch
are different from each other.
Check the models.
Copying is available when
the pressure range, output
specification and unit
specification are identical.
Error in
connected
product
numbers
Check the number of connected
slave Pressure switches.
The number of connected
products with which copying
at a time is possible is up to
10 pcs.
Reduce the number to
10 pcs or less.
18
Slave Pressure
switch does not
complete
copying.
Product failure Replace the product.
Effect of
pressure source
fluctuation due
to small
hysteresis or too
early of a
response time
(1) Check the set pressure
(hysteresis)
(2) Check the response time
(1) Check the pressure
setting.
(2) Reset the setting of
function.
Incorrect wiring/
lead wire
breakage
(1) Check the power supply wiring.
(2) Check if bending stress is applied
to a specific part of the lead wire.
(bending radius and tensile force
applied to the lead wire)
(1) Correct the wiring
(2) Correct the wiring
conditions. (Adjust the
tensile force and widen
the bending radius.)
19
The operation is
unstable.
(Chattering)
Product failure Replace the product.
