SUP port (Supply port)

Atmospheric vent port

•Connect tubing (sold separately) to the atmospheric
vent port if there is a possibility that the port could be
blocked by water or dust.

•Recommended tube is TU0425 (material: polyurethane,
O.D. ø4, I.D. ø2.5) made by SMC.

•The other end of the air tubing should be routed to a
safe place to prevent it from being exposed to water
or dust.

•Ensure the tubing has no sharp bends.

not in the range 80 kPa to 220 kPa.
Measurement is not possible.

Supply rated pressure.
(100 kPa to 200 kPa)

Main display Name Description Measures

Display value is outside the
displayable range
(switch point setting mode)

The switch output (OUT1) load
current has exceeded 80 mA.

An internal data error has occurred.

Turn the power off and remove
the cause of the over current.
Then turn the power on again.

Zero clear error

Zero clear was performed in
non-atmospheric pressure.
(Pressure outside of ±14 kPa was
supplied at factory default settings.)

Perform zero clear at
atmospheric pressure.

〜

The workpiece is outside the
