(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.
Check the model numbers.
Copying is available when
the pressure range, output
specification and units
specification are identical.
The number of connected
products for which copying
is possible is up to 10 pcs.
Reduce the number to
10 pcs. or less.
Replace the product.
(1) Check the pressure
setting.
(2) Reset the function
settings.
(1) Correct the wiring
(2) Correct the wiring
conditions (reduce the
tensile force and
increase the bending
radius).
Replace the product.
