٨When connecting a commercial coupler to the pressure port, attach a
12mm spanner (14mm for DP-100-E type) to the pressure port's hexa-
gon section to fix the port, and then tighten with a tightening torque of
9.8N䊶m or less. The commercial coupler or pressure port section will be
damaged if the tightening torque is excessive.
Wrap sealing tape around the coupler when connecting to prevent leaks.

Be sure to use the setting copy function between the identical models.
This function cannot be used between different models.
Only one sensor can be connected on slave side with a master side sensor for the setting copy function.
Notes: 1) For the high-function type, analog voltage / external input.
Ԙ
ԙ
Ԛ
Set the setting copy function of the master side sensor to 'Copy sending ON' or
'Copy sending ON-L', and then press the mode selection key so that the sensor is in
copy ready state. For details, refer to <Setting copy mode> in ' PRO MODE'.
Turn off the master side sensor.
Connect the master side sensor with the slave side sensor as shown below.
<Setting procedure>
Notes: 2)
3)
Take care that if the power is not turned on at the same time, the setting con-
tents may not be copied.
Note that when the power is on, pulse output is output to comparative output 1.
<To cancel the setting copy mode of master side sensor>

Whilst the slave side sensor is disconnected, turn on the power of the
master side sensor.
Press the mode selection key for approx. two seconds.

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 0.3mm2, or more, cable. However, in case
CE conformity is not required, the cable length can be up to 100m with 0.3mm2, or more, cable.

AUTO-REFERENCE FUNCTION
(ONLY HIGH-FUNCTION TYPE)
12
٨
٨
The auto-reference function corrects the setting value using the detected
pressure value during
auto-reference input as
the reference pressure.
Using the setting value P-A
as a reference, the setting
value is automatically correct-
ed to 'setting value + P-A'.
٨The 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 during auto-
reference input, the setting value will be automatically corrected to within the
set pressure range. Thus, take care not to exceed the set pressure range.
࡮Auto-reference input: 30kPa
࡮Output mode: Hysteresis mode
Note: The setting values shift in the same manner during the EASY mode or the win-
dow comparator mode.

The auto-reference input value becomes 'zero' when the setting of the analog volt-
age output / external input selection 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 ' RUN MODE'
for details..

REMOTE ZERO-ADJUSTMENT FUNCTION
(HIGH-FUNCTION TYPE)
13
٨The 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-

٨ The remote zero-adjust input 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
' RUN MODE'.

Applied pressure range should be brought within
the rated pressure range.
Check the wiring when using the copy function.
Communication error
(Disconnection, faulty connection, etc.)
The pressure during threshold set-
ting exceeds the set pressure range.
Make sure that the system is configured of the
same models when using the copy function.
Communication error
(Incorrect model.)
Applied pressure range should be brought within
the rated pressure range.
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.
Applied pressure at the pressure port should be brought to atmos-
pheric pressure and zero-point adjustment should be done again.
Pressure is applied during
zero-point adjustment.
Turn the power OFF and check the load.
The load is short-circuited caus-
ing an overcurrent to flow.
