AUTO-REFERENCE FUNCTION (ONLY HIGH-FUNCTION TYPE)
● The auto-reference function
corrects the set value using the
detected pressure value during
auto-reference input as the refer-
ence pressure.
● Using the detected pressure val-
ue at auto-reference input P(a)
as a reference, the set value
1
’
is automatically corrected to “set
value
1
+ P(a)”.

Settable range and set pressure range after correction
● The set pressure range is wider than the rating pressure range so that the auto-
reference function can be handled.
If the corrected set value exceeds the set pressure range when auto-reference input
is carried out, the set value will be automatically corrected to within the set pressure
range. Thus, take care not to exceed the set pressure range.

Note: The set values shift in the same manner during the EASY mode or the window comparator mode.
● The detected pressure value at auto-reference input becomes “zero” when the set-
ting of the external input selection function is changed or the power is turned ON
again.
● The auto-reference input value can be checked when setting the threshold value in
RUN mode. Refer to the threshold value setting in “
7
RUN MODE
” for details.

REMOTE ZERO-ADJUSTMENT FUNCTION (HIGH-FUNCTION TYPE)
● The remote zero-adjustment function forcibly sets the pressure value to “zero” when
the external signal is inputted.
The set value is not corrected when remote zero-adjustment is input. Make sure that the
pressure and set value during remote zero-adjustment do not exceed the set pressure
range.

● The remote zero-adjustment value is cleared when the setting of the external input
selection is changed or the power is turned ON again, and normal operation based
on the atmospheric pressure is resumed.
● The remote zero-adjustment value can be confirmed when setting the threshold
value in RUN mode. Refer to the threshold value setting in “

ERROR INDICATION
Error message
Cause
Corrective action
The load is short-circuited causing
Turn the power OFF and check the load.
Pressure is applied during zero-
point adjustment.
Applied pressure at the pressure port should be brought to
atmospheric pressure and zero-point adjustment should be
done again.
External input is carried out outside
the rated pressure range.
Applied pressure range should be brought within the rated
pressure range.
Communication error
(Disconnection, faulty connection, etc.)
Check the wiring when using the copy function.
Communication error
(Incorrect model.)
when using the copy function.
The applied pressure exceeds the
upper limit of the display pressure
range.
Applied pressure range should be brought within the rated
pressure range.
The applied pressure exceeds the
lower limit of the display pressure
range.

CAUTIONS
● This product has been developed / produced for industrial use only.
● Use within the rated pressure range.
● Do not apply pressure exceeding the pressure withstandability value. The dia-
phragm will get damaged and correct operation shall not be maintained.
● Make sure that the power supply is off while wiring.
● Take care that wrong wiring will damage the sensor.
● Verify that the supply voltage variation is within the rating.
● If power is supplied from a commercial switching regulator, ensure that the frame
ground (F.G.) terminal of the power supply is connected to an actual ground.
● In case noise generating equipment (switching regulator, inverter motor, etc.) is
used in the vicinity of this sensor, connect the frame ground (F.G.) terminal of the
equipment to an actual ground.
● Do not use during the initial transient time (0.5 sec.) after the power supply is
switched on.
● Extension up to total 100m or less, is possible with more than 0.3mm
2
of electric
conductor cross-sectional area cable.
● In case of using this product as a CE Marking conformity product, the wire con-
nected to this product must be within 30m.
● Do not run the wires together with high-voltage lines or power lines or put them in
the same raceway. This can cause malfunction due to induction.
●
● Avoid dust, dirt, and steam.
● Take care that the sensor does not come in direct contact with water, oil, grease, or
organic solvents, such as, thinner, etc.
● Do not insert wires, etc, into the pressure port. The diaphragm will get damaged
and correct operation shall not be maintained.
● Do not operate the keys with pointed or sharp objects.
● Make sure that stress by forcible bend or pulling is not applied directly to the sensor
cable joint.
