IMPORTANT:
Install the product to a pipe so that they are electrically connected at the same potential. If the valve and the
pipe are electrically isolated, noise might be generated, causing incorrect measurement and control of flow.
When installing the product with flange gasket, do not use the rubber gasket or the gasket that goes inside the
pipe. Doing so might cause incorrect measurement and control of flow.
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 rate 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.
Do not loosen the yoke fixing screws or the actuator fixing screws. Loose fixing screws lower flow measuring
accuracy. Note that the actuator mounting position onto the valve cannot be changed.
Flow measuring accuracy in the subsection Measuring range and accuracy shown later is for the valve
sensor measuring 44.6 to 62.6 F (7 to 17 °C) and 113 to 149 F (45 to 65 °C) ranges, 29 to 261 psig pipe
pressure, and 4.35 to 43.5 psig differential pressure. Without these ranges, the flow rate measuring accuracy
might decrease.
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 might damage the valve sensor and cause error output.

Notes:
3 Valve sensor is the temperature and pressure sensors mounted onto the valve (Model FVY5137J), measuring valve surface temperature
and inlet and outlet flow pressure.
4 When you test the withstand pressure, up to 232 psig pressure can be applied to the valve sensor.
5 The above pressure measuring accuracy is for the 44.6 to 149 °F (7 to 65 °C) flow temperature. If the flow temperature is out of the 44.6 to
149 °F (7 to 65 °C), the valve sensor flow measuring accuracy may decrease.
6 For accurate measuring of flow temperature, thermal insulation is required. Refer to the subsection Heat insulation for applying thermal
insulation.
7 Overall accuracy is calculated based on the sensing accuracy of the temperature sensors connected, the conversion accuracy, and the
error due to wiring length.
8 Energy calculation accuracy is calculated from the flow measuring accuracy at 1.8 °F (1 °C) measuring error of the temperature difference.
9 The flow measuring accuracy in the table corresponds to the data shown in the above flow measuring accuracy graph.

Precautions for installation
WARNING
Some of the product models weigh more than 40 lb (18.1 kg). Carefully move the product with a vehicle or enough
manpower in an appropriate manner. Careless lift or accidental drop of the product might cause injury or product
damage.
CAUTION
Keep the products in package for storage. Failure to do so might damage or stain the products.
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
For installation, do not mount the valve in an improper position or overtighten the bolts on the flange. Doing so might
damage the product.
Install the product to a pipe so that they are electrically connected at the same potential. If the valve and the pipe are
electrically isolated, noise might be generated, causing incorrect measurement and control of flow.

Install the product so that no foreign objects remains inside the pipes. Be sure to provide a strainer on the inflow side
of the piping. Flush the piping to remove the foreign objects after installation. Foreign objects inside the piping might
damage the product.
After installation, make sure no fluid leaks from the valve-pipe connections. Incorrect installation might cause fluid
leakage
IMPORTANT:
This product requires straight pipe runs (valve diameter

2 long) on the inlet and outlet sides for accurate flow
measuring.
When installing the product with flange gasket, do not use the rubber gasket or the gasket that goes inside the
pipe. Doing so might cause incorrect measurement and control of flow.
Model FVY5137J 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. If 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 product so that the flow direction of process fluid agrees with the arrow indicated on its 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.
When installing the product to the pipes, do not allow any object, such as chips, to get inside a pipe or the valve. The valve
cannot fully close, or the valve seat may get damaged causing fluid leakage, due to an object jammed inside the valve.
When piping, do not apply too much sealing material, such as solidifying liquid and tape, to the pipe connection sections so
that these materials flow into the valve. The valve cannot fully close, or the valve seat may get damaged causing fluid
leakage, due to the sealing material jammed inside the valve.
Before activating the product, fully open (in 100 % position) the valve and flush the pipes (with the product installed) at the
maximum flow rate 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 decrease. 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
WARNING
Detach the cover only when wiring, setting the product or maintenance and reattach the cover after wiring, setting the
product or maintenance. Failure to do so might cause electric shock.
Before wiring or maintenance, be sure to turn off the power to the product. Failure to do so might cause electric shock
or device failure.
CAUTION
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
All wiring must comply with applicable codes and ordinances.
Provide circuit breaker/fuse protection when powering this product.
Provide a circuit protector (e.g., a fuse, circuit breaker) for the control panel to ensure your safety.

For wiring, strip each wire insulation as specified in this manual. If the strip length is longer than the specified, the
stripped part of the wires might be exposed, causing electric shock or short circuit between adjacent terminals. If it is
shorter, the stripped part might not contact the connector.
Use crimp terminals with insulation for connections to the product terminals. Failure to do so might cause short circuit
leading to fire or device failure.
Firmly tighten the terminal screws. Insufficient tightening of the terminal screws might cause fire or overheating.
IMPORTANT:
The product is designed for 24 V AC power supply voltage.
Do not apply any other power voltage (e.g., 120 V AC, 240 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 and after connecting
the wires.
Wiring procedure
1) To lead the wires into the terminals, open a knockout for a wiring port. Two knockouts are provided on the bilateral sides of
the actuator terminals. Select a knockout according to the conduit mounting direction, and open the hole by lightly knocking
the knockout using a screwdriver.
2) Unscrew the 3 setscrews (M4 10) of the terminal cover and remove the terminal cover, as shown in Fig. 9.

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) 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 0.04" (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.

4) Plug the connector into the actuator socket.
Note:
Completely plug the connector into the actuator socket. Incompletely plugged connector might become unplugged due to vibration.
Wires connection of control signal, DI (Cooling/heating switch signal), pulse output
1) Pass the cable of control signal/DI/pulse output through a wiring port on the other side of the port for power supply cable.
2) Use 4- or 6-core cable for connecting the wires of the multiple signal lines.
Precautions for connection
1. RS-485 communication (See Figs. 25 and 26.):
Pass the cable of RS-485 communication through a wiring port (knockout) 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 connector unplugged 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. 27 and 28.):
Apply 30 V DC or lower voltage (on '+V' shown in Fig. 27).
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 NEMA 4X, 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
(AWG 18–22 x 3-core 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.
Insert a screwdriver.
Insert a wire.
Lightly pull out
connected wires.

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 to 20 mA input type products (See Figs. 22 and 23.):
4 to 20 mA control signal input is not isolated from the power, and the 4 to 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 to 20 mA input terminal of the second product. The products will
malfunction without the isolator.
