(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

(1) Correct the wiring
(2) Correct the wiring
conditions (reduce the
