Infilex™ AC

Air Handling Unit Controller for NC-bus Communication

General

Infilex AC Model WY5117C1XXX is a DDC controller for AHU. It is installed in a small space such as an AHU control panel.

Infilex AC is equipped with inputs and outputs suitable for AHU control, and its software is freely editable in response to the applications.

Operator interface and room user terminal are connectable to Infilex AC, supporting you in various situations to operate Infilex AC.

Infilex AC also is networked with our BMS via our proprietary protocol NC-bus. Infilex AC sends operating status to the BMS and performs operating management in accordance with the commands sent from the BMS in order for you to integrally control and manage a whole building.

The time scheduling function of Infilex AC, on the other hand, enables autonomous-distributed control.

AHU: Air handling unit BMS: Building management system DDC: Direct digital control

Features

Compact design: Small sized body fits inside a control panel of a compact AHU.

Wide range of input/output (I/O) combinations: Model with the I/O combination best-suitable for the air conditioning controls you desire, such as outdoor air cooling control, humidification, etc. is selectable.

Increase in I/O points: An I/O module is added to Model WY5117C140X for increasing the I/O points.

Operator interface (Operator Panel): Operator Panel (panel mount type/integral type) connected to Infilex AC allows you to change the settings of Infilex AC without accessing Infilex AC from the BMS.

Room user terminals: User terminal (Neopanel or Neoplate) is connectable to Infilex AC, enabling the room occupants to turn on/off air conditioning unit and change temperature setting.

Cooperation with BMS: Infilex AC is networked with our BMS to centrally monitor and control AHU.

Autonomous distributed control: Even if a trouble occurs in the BMS, Infilex AC individually performs backup operation to distribute potential risks caused by malfunction of the BMS.

Installation: Screwless push-in terminals for I/O reduce wiring workload. Additionally, either DIN rail mount or screw mount is selectable.

CE Marking certified product: Infilex AC Model WY5117C conforms to all the applicable standards of CE Marking.

Sheath strip length: 8 mm (Pin terminal cannot be used.) *4 RTD (Pt1000) temperature input is two-wire. Take the measuring error into account because the wire resistance causes measuring error.

For instance, 1.25 mm2 size wire causes approx. 0.1 °C measuring error every 10 m. Correct the measuring error by setting Infilex AC. *5 When the valve/damper is connected for the system common wiring, the valve/damper operating current flows through the common line.

Hence, the specification is as shown above. For a 20 m long IV 1.25 mm2 cable, 4-wire connection is necessary to prevent the operating current from flowing through the common line.

Wiring

WARNING

Detach the terminal cover only when wiring the product. Before detaching the terminal cover, be sure to turn off the power to the product and all the connected devices. After wiring, be sure to reattach the terminal cover. Failure to do so might cause electric shock.

Before wiring and maintenance, be sure to turn off the power to the product. Failure to do so might cause electric shock.

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.

Firmly tighten the terminal screws. Insufficient tightening of the terminal screws might cause fire or overheating.

For wiring, strip each wire insulation for the length specified in this manual. If the strip length is longer than the specified, the stripped part of the wires will be exposed, causing electric shock or short circuit between adjacent terminals. If it is shorter, the stripped part will not contact the connector.

Do not use unused/spare terminals on the product as relay terminals. Doing so might cause malfunction.

Do not block the ventilation holes of this product. (Be sure to peel off the protective sheet after installation and wiring).Doing so might cause device failure.

Precautions for wiring

Tube marker:

Since Infilex AC adopts the screwless push-in terminals, wires are connected without crimping terminal lugs. Therefore, if normal tube markers are used, they may come off when you disconnect the wires. To prevent this, use the following Flat Tube Marker. It is held on a wire by friction and thus does not come off easily.

Flat Tube Marker Manufacturer Phoenix Contact Item number 5880029 Model TMC-3 Applicable wire size 0.4 mm2 to 2 mm2 Package unit 200 m/roll

2 mm2 cable running outside the control panel: Use an external terminal block to switch to 1.25 mm2 cable inside the control panel.

Two wires for one terminal: Use an external terminal block to aggregate the wires.

Fan ON/OFF: Use a small-power circuit (max. 60 V operating voltage and 1.5 A operating current) to turn on and off fan.

Signal wire for output to inverter: Use a shielded cable.

Power supply wiring

Crimp M3 terminal lugs with insulation on the wire ends, and connect the wires to the power supply terminals.

Wiring to I/O and NC-bus terminals

The I/O and NC-bus wires are connected to the screwless push-in terminals of Infilex AC. Follow the procedure below for the I/O and NC-bus wiring.

1) Strip the wire sheath 8 mm. Note: * Scale for the strip length is indicated on the front surface of Infilex AC basic unit. If the insulation stripped part is longer than 8 mm, it

may get exposed, causing electrical shock or short circuit between adjacent terminals. If it is shorter, it may not contact the terminal connector.

2) Make sure that no wire fiber goes out of the wire end.

3) Press the button on the terminal block deeply enough using a slotted screwdriver and insert the wire. (Maximum button-pressing force is 23 N.) Then, release the button.

4) Gently pull out the wire horizontally to make sure that it is completely held by the clamp and check no wire fiber being disconnected from the terminal.

Note: * If you pull out the wire diagonally, it may be disconnected.

Arrangement of the wires connected to Infilex AC

Notes: * Neatly place the wires using cable ties or the like so as not to hide LED, Data Setter connector, mark of Data Setter connector, S1 switch,

battery holder, and indication tag. * Do not leave slack in the wires that run between the cable duct and Infilex AC. * Sideway mounting shown in the figure above is allowed only when I/O module, UT module, or integral type Operator Panel is NOT

assembled with the basic unit. Do not mount the Infilex AC basic unit sideway with the power supply terminals located upper corner, lying on its back, or lying face down. Always install the basic unit assembled with an I/O module, and/or UT module/integral type Operator Panel in upright position.

Precautions for Wiring of Infilex AC and Devices

System common wiring

Ground line () is used as a common line for signal transmission to/from the field devices. For the system common, the common-mode power must be supplied to Infilex AC and each device (such as ACTIVAL™) via the wires connected to "~" and "" terminals of Infilex AC and each device. For the signal transmission between Infilex AC and each device, use "" wiring.

Figure 10. Wiring example: System common wiring

IMPORTANT:

Use an isolation transformer. Do not ground the secondary side of the transformer.

Provide a terminal block aright ahead of the transformer, and divide the line at the terminal block to connect to each device. (See Fig. 10.)

Inverter

Figure 11. Wiring example: Inverter

IMPORTANT:

Shielded cable must be single-point grounded on the inverter.

IMPORTANT:

If Infilex AC and a humidity sensor are powered by a single transformer, the sensor might get damaged. Depending on the other connected devices and on the wiring condition, a short-circuit current may flow into the sensor and into the Infilex AC.

Precautions for Use

Before supplying the power

Check that the all the wires are correctly connected.

Remove the protective sheet from the top surface of Infilex AC. Note: * if some foreign objects possibly come inside Infilex AC from the ventilation holes on the side and bottom surfaces, cover the ventilation

holes with sheets.

Several tens of seconds are required for the Infilex AC normal operation after the power is turned on. During this time, the red LED on the front stays ON temporarily, but this does not indicate an error.
