AUTO-REFERENCE FUNCTION

(ONLY HIGH-FUNCTION TYPE)
The auto-reference function corrects
the setting value using the detected
pressure value during auto-reference
input as the reference pressure.
Using the detected pressure value at
auto-reference input P(a) as a refer-
ence, the set value ' is automatical-
ly corrected to 'set value + P(a)'.
Settable range and set pressure range after correction
The setting pressure range is wider than the rating pressure range so
that the auto-reference function can be handled.
If the corrected setting value exceeds the set pressure range when auto-reference input is
carried out, the setting value will be automatically corrected to within the set pressure range.
Thus, take care not to exceed the set pressure range.

Note: The setting values shift in the same manner during the EASY mode or the win-
dow comparator mode.
The detected pressure value at auto-reference input becomes 'zero'
when the setting of the analog voltage output / 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 '

REMOTE ZERO-ADJUSTMENT FUNCTION

(HIGH-FUNCTION TYPE)
The remote zero-adjustment function forcibly sets the pressure value to
'zero' when the external signal is input.
The setting value is not corrected when remote zero-adjustment is input.
Make sure that the pressure and setting value during remote zero-adjust-
ment do not exceed the settable pressure range.

Note: The setting values shift in the same manner during the EASY mode or the win-
dow comparator mode.
The remote zero-adjustment value is cleared when the setting of the analog
voltage output / 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
' 8 RUN MODE'.
14 ERROR INDICATION
Cause
Error message
The load is short-circuited caus-
ing an overcurrent to flow.
Pressure is applied during
zero-point adjustment.
External input is carried out out-
side the rated pressure range.
Communication error
(Disconnection, faulty connection, etc.)
Communication error
(Incorrect model.)
The applied pressure exceeds the up-
per limit of the display pressure range.
The applied pressure exceeds the lower limit (re-
verse pressure) of the display pressure range.

Corrective action
Turn the power OFF and check the load.
Applied pressure at the pressure port should be brought to atmos-
pheric pressure and zero-point adjustment should be done again.
Applied pressure range should be brought within
the rated pressure range.
Check the wiring when using the copy function.
Make sure that the system is configured of the
same models when using the copy function.
Applied pressure range should be brought within
the rated pressure range.

CAUTIONS

DP-100 series is designed for use with non-corrosive gas. It cannot be
used for liquid or corrosive gas.
Use within the rated pressure range.
Do not apply pressure exceeding the pressure withstandability value. The
diaphragm 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 vicini-
ty 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.
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.
The specification may not be satisfied in a strong magnetic field.
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.
This is a CE conformity product complying with EMC Directive. The standard with regard to im-
munity that applies to this product is EN 61000-6-2, and in order to meet the standard, every ca-
ble connected to this product must be within 10m with 0.3mm
CE conformity is not required, the cable length can be up to 100m with 0.3mm
