Notes: 1) In the case of a model that is intended for use outside Japan, attach the unit switch plate corresponds to the set
pressure unit.
2) The product for use inside Japan can be set only to “MPa” or “kPa”.
2 PIPING
● When connecting a commercial coupler to the pressure
port, attach a 12mm spanner to the pressure port’s
hexagon section to fix the port, and then tighten with a
tightening torque of 9.8N·m or less (M5 female: 1N·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 connect-
ing to prevent leaks.

3 MOUNTING
● The sensor mounting bracket GS6-B is available as an option. When mounting the sensor
onto the sensor mounting bracket, etc., the tightening torque should be 0.5N·m or less.

plete.)
7. Turn OFF the power of the master side sensor and the slave side sensor and dis-
connect the wire.
* If copying the setting to another sensor repeatedly, follow steps 3 to 7.
Notes: 2) Take care that if the power is not turned on at the same time, the setting contents may not be copied.
3) 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
1. Whilst the slave side sensor is disconnected, turn on the power of the master side
sensor.
2. Press the mode selection key for approx. 2 seconds.
11 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)”.

Set value 1’ after auto-reference is:

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.
12 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.

15 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.
● 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.

15 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.
● 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.

Frequently Answers and Questions
What are the different types of pressure units supported by the Koganei GS6 Series?
The Koganei GS6 Series supports various pressure units including MPa, kPa, bar, psi, inchHg, and mmHg. The specific units available for the device may vary depending on the model.
How do I change the pressure unit displayed on the Koganei GS6 Series?
You can change the pressure unit by accessing the "Unit Selection" setting within the device. Refer to the "7 RUN MODE" section in the instruction manual for detailed instructions.
How do I set the output mode for the comparative outputs on the Koganei GS6 Series?
The Koganei GS6 Series offers three output modes for comparative outputs 1 and 2: EASY mode, Hysteresis mode, and Window Comparator mode. To select the desired mode, navigate to the "Comparative output 1/2 output mode setting" in the "8 MENU SETTING MODE" section of the instruction manual.
