IMPORTANT:
•This product is applicable only to chilled/hot water control. If the product is used to control any other medium
such as brine or air, flow cannot be measured or controlled.
•Install the valve so that the flow direction of process fluid agrees with the arrow indicated on the valve body. If
the flow direction is opposite to the arrow, correct measurement and control of flow is not assured.
•The actuator mounting position onto the valve cannot be changed. Therefore, do not loosen the yoke fixing
screws or the actuator fixing screws. Loose fixing screws lower flow measuring accuracy.
•Flow measuring accuracy in the subsection Measuring range and accuracy shown later is for the valve
sensor measuring 7 to 17 °C and 45 to 65 °C ranges, 0.1 to 0.8 MPa pipe pressure, and 0.03 to 0.3 MPa
differential pressure. Without these ranges, the flow measuring accuracy may lower.
•To keep flow measuring accuracy, control the quality of process fluid (water), and do not allow rust or foreign
object inside the valve. Rust or foreign object inside the valve lowers flow measuring accuracy.
•Thermally insulate the valve, and do not allow the process fluid to freeze. Frozen process fluid around the valve
sensor may damage the valve sensor and cause error output.

Installation
Precautions for installation
CAUTION

•Installation and wiring must be performed by
qualified personnel in accordance with all
applicable safety standards.

•Install the product in the proper position as
specified in this manual.
Excessively tight connection to a pipe or
improper installation position might damage the
product.

•Do not use rubber gaskets.
Doing so might cause incorrect measurement
and control of flow.

•After installation, make sure no fluid leaks from
the valve-pipe connections.
Incorrect installation might cause fluid leakage.

•Do not allow any foreign objects inside the pipes
during installation. Flush the piping to remove the
foreign objects after installation.
Foreign objects inside the piping might damage
the product.

•Install the valve to the pipe so that they are
electrically connected at the same potential. If
the valve and the pipe are electrically isolated,
noise will be generated, causing incorrect
measurement and control of flow.
IMPORTANT:
Model FVY5137J/FVY5147J/FVY5157J requires
straight pipe runs (valve diameter ×2 long) on the
inlet and outlet sides for accurate flow measuring.
•Model FVY5137J/FVY5147J/FVY5157J is the valve and
actuator integrated into a single unit. Do not combine the
valve with any other actuator, or do not combine the
actuator with any other valve.
•To remove foreign objects inside the pipes, install a
strainer with 40 or more meshes on the inflow side of
each valve. In a case that the strainers cannot be
installed on the inflow side of each valve, install it on the
pipe diverting sections (sections diverting from main
piping system to sub piping system).
•Install the valve so that the flow direction of process fluid
agrees with the arrow indicated on the valve body.

Piping
IMPORTANT:
Do not put force on the valve sensor or its cable to prevent failure.
•Check that the model number of the product is what you ordered. The model number is shown on the label attached to the
yoke.
•Install a bypass pipe and gate valves on the inflow, outflow, and bypass sides. Also, install a strainer with 40 or more
meshes on the inflow side.
•Before activating the product, fully open (in 100 % position) the valve and flush the pipes (with the product installed) at the
maximum flow to remove all the foreign objects. (Factory preset position: 100 %)
Heat insulation
Apply heat insulation to the valve, as and shown in Fig. 2. Do not apply it to the yoke or the actuator. If the heat
insulation is inappropriate, temperature measuring accuracy may lower. If the yoke and/or the actuator are covered with
insulation material, the pointer cannot be checked or may be distorted.
When cutting the insulation material that covers the valve, be sure not to damage the valve sensor cable.

Wiring
CAUTION
•Installation and wiring must be performed by qualified personnel in accordance with all applicable safety
standards.
•Before wiring and maintenance, be sure to turn off the power to the product.
Failure to do so might cause electric shock.
IMPORTANT:
•This product is designed for 24 V AC power supply voltage.
Do not apply any other power voltage (e.g., 100 V AC, 200 V AC) to the product.
•To prevent damage, cover the terminals except when connecting/disconnecting wires.
•Do not leave any refuse including metal chips inside the actuator after cutting a knockout hole and after
connecting the wires.
Wiring procedure
1) To lead the wires into the terminals, cut out a knockout hole for a wiring port. Two knockout holes are provided on the
bilateral sides of the actuator terminals. Select a knockout hole according to the conduit mounting direction, and cut it out by
lightly knocking the hole using a screwdriver.
2) Unscrew the 3 setscrews (M4 ×10) of the terminal cover and remove the terminal cover, as shown in Fig. 9.
Figure 8. Knockout hole for wiring port Figure 9. Terminal cover removal
3) Refer to Figs. 3 and 10 and correctly connect the wires to the M3.5 screw terminals. Note that the wires of the temperature
sensor, Display Panel, and RS-485 communication lines are connected to the connectors.
Figure 10. Terminals arrangement
4) Separate the power supply line from the signal lines. Do not lead the power supply line through the wiring port (knockout
hole) for the signal lines since the power supply line may generate noise causing operation error and failure.

5) Connect the wires of each line. After connecting the wires, lightly pull them from the wiring ports so that minimum wire slack
remains inside the actuator. Too long wire slack inside the actuator may block the terminal cover to close or may hold down
the reset switch and interrupt the operation. See Fig. 3 for the location of the reset switch.
6) Tighten the seal connectors of the wiring ports. On the wiring ports for Display Panel cable and temperature sensor (Pt100
input) cable, tighten the seal connectors until the clearance between the wiring port and the seal connector becomes
narrower than 1 mm.
Cable may get twisted as you tighten the seal connector. In such a case, loosen and remove the seal connector and untwist
the cable, then re-tighten the seal connector.

Precautions for connection
1. RS-485 communication (See Figs. 26 and 27.):
•Pass the cable of RS-485 communication through a wiring port (knockout hole) on the other side of the wiring port for power
supply cable. Attach the optional cable gland with three ports (Model DY7000A1000) to the wiring port to share the wiring
port with signal lines.
•Connect the wires of RS-485 communication cable to the unplugged connector from the actuator socket. After connecting
the wires to the connector, plug the connector into the socket.
•Do not use terminators.
•Do not connect between the terminals DA and DB.
•Single-point ground is required for one side of the shielded cable.
•Connect SG wire for stable communication link.
•To daisy-chain the communication line, connect the wires of the receiving line to the terminals In DA, In DB, and In SG.
Connect the wires of the sending line to the terminals Out DA, Out DB, and Out SG.
2. Pulse output (See Figs. 28 and 29.):
•Apply 30 V DC or lower voltage (on '+V' shown in Fig. 28).
•Do not directly connect the DC power to the pulse output terminal.
•To use a magnetic counter with a relay coil, refer to Fig. 29 and connect a protection diode to the input of the magnetic
counter.
3. Temperature sensor for pipe surface:
Since the 3-core cable of the temperature sensor for pipe surface has small diameter, the seal connector pre-assembled
with the product is not enough to ensure the IEC IP54 protection. Caulk the seal connector or apply the tape to seal the
connector.
4. Insertion-type pipe temperature sensor:
Use the seal connector Part No. 83104098-001 for the cable of the insertion-type pipe temperature sensor (JIS VTCF 0.3
mm2×3 cores or equivalent.)
5. Internal isolation:
Only the pulse output and the RS-485 communication are internally isolated. Isolator therefore is required to connect a
non-isolated device to the control signal input and DI (Cooling/heating switch signal) of the product.

6. Single transformer with two products (See Fig. 21.):
Connect the lines from the terminal 1 of each product to the transformer with the same polarity. Connect the lines from the
terminal 2 of each product the same way. If the terminals (of the product and the transformer) with different polarities are
connected, the products may get damaged.
7. Single controller with multiple 4-20 mA input type products (See Figs. 22 and 23):
4-20 mA control signal input is not isolated from the power, and the 4-20 mA input impedance is 250 Ω. For connecting a
controller, the relations among the input impedance of this product, the output load resistance of the controller, and the
output load resistance and input impedance of an isolator (if necessary) must meet the following formula.
Applicable load resistance > Total input impedance
To operate the two products with a single controller for example, refer to Fig. 22 for the two products powered by a single
transformer, and refer to Fig. 23 for the two products separately powered by the two transformers. To connect a single
transformer, be sure to connect an isolator to the 4-20 mA input terminal of the second product. The products will
malfunction without the isolator.
8. Single controller with multiple 2-10 V input type or 0-10 V input type products (See Figs. 24 and 25.):
2-10 V/0-10 V control signal input is not isolated from the power.
To operate the two products with a single controller for example, the two products must be powered by a single transformer.
