1. MOUNTING METHOD
First, Fix the terminal board to the wall as shown in the gure
below (*). Then x the main body on terminal board with two
screws.
* Terminal board can be detached from the main body by
removing two screws.

The PF1 can be mounted on the Air Supply Unit (PPU) and
can be mixed mounting with the PH10 (Electrical to Pneumatic
Converter).
The mounting method is the same as PH10. Refer to the PH10
user’s manual.
• Document number: IM 77J10P10-01EN
2. INSTALLATION AND ENVIRONMENTAL
CONDITIONS
• Avoid the following environments for installation locations:
Areas with vibrations, corrosive gases, dust, water, oil,
solvents, direct sunlight, radiation, a strong electric eld,
and/or a strong magnetic eld, direct radiant heat, wind,
temperature uctuation.
• If there is any risk of a surge being induced into the power line
and/or signal lines due to lightning or other factors, a dedicated
lightning arrester should be used as protection for both the
product and a eld-installed device.
• Use indoors at an altitude of 2000 m or less.
• Operating temperature/humidity range: 0 to 50°C/5 to 90%RH
(no condensation)
3. AUTOMATIC SEALING
When main body of the PF1 is removed from the terminal board,
air will be sealed automatically by closing a valve of terminal
board.
4. PIPING
Connect pipe for input pneumatic signal to inlet (Rc 1/4 (PT 1/4
female thread)) of terminal board. The thread size for pipes is R
1/4 (PT 1/4 male thread).
CAUTION
Fastening torque of pipe is 2±0.5 N•m
5. EXTERNAL WIRING
WARNING
●To avoid the risk of an electric shock, turn o󰀨 the
power supply and use a tester or similar device to
ensure that no power is supplied to a cable to be
connected, before carrying out wiring work.
●Do not operate the product in the presence of
ammable or explosive gases or vapors. To do so is
highly dangerous.
●Use of the product ignoring the specications may
cause overheating or damage. Before turning on
the power, ensure the following:
•Power supply voltage and input signal value
applied to the product should meet the required
specications.
•The external wiring to the terminals and wiring to
ground are as specications.
Wiring should be connected to the terminals on the socket of the
product. The terminals for external connections are of M3 screws.
Use crimp-on terminal lugs for connections to the terminals.
• Recommended cables: A nominal cross-sectional area of
0.5 mm2or thicker for signal cables, and that of 1.25 mm2or
thicker for power cables.

6. MAINTENANCE
The product starts running immediately when the power is turned
on; however, it needs 10 to 15 minutes of warm-up before it
meets the specied performance.
6.1 Calibration Apparatus
• A Pneumatic Pressure Standard (YOKOGAWA MC100 or the
equivalent)
• A DC Voltage/Current Source (YOKOGAWA GS200 or the
equivalent)
6.2 Calibration Procedure

2. Use the pneumatic pressure standard and apply input signals
equivalent to 0, 25, 50, 75, and 100% of the input span to the
product.
3. Check to see the corresponding output voltages are 0, 25, 50,
75, and 100% respectively and within the specied accuracy
rating.
• If the output signals are out of the accuracy rating range,
adjust the output signal level using the zero and span
adjustment volumes on front face of the product.
