2 Usage  
The AI controller measures temperature and humidity; it also has an alarm capability if the measurement data exceeds  
defined setpoints. Historical measurement data can be displayed via only the G(B)-50A Web browser and TG-2000A.  
Temperature and humidity cannot be displayed on the G-50A LCD.  
Furthermore, an alarm can be output if measurement data exceeds a preset upper or lower limit.  
The AI controller also features a function that interlocks M-NET devices for indoor units, etc. set in advance and performs  
settings such as temperature control and operation/stoppage using measurement data values.

* This figure omits the power supply line and only shows the transmission line.  
Note:  
• For the shield ground of the M-NET centralized control line, use single-point grounding at the power unit for the transmission  
line.  
However, when supplying electric power to the M-NET centralized control line from the R410A series outdoor unit without  
using a power supply unit for the transmission line, use single-point grounding at the TB7 of that outdoor unit.  
Furthermore, when connecting the M-NET transmission line of this device to the M-NET indoor control line, use grounding  
at the TB3 for each outdoor unit system.  
• If the M-NET transmission line of this device is connected to an M-NET indoor control line and the outdoor unit is down  
because, for example, the power supply is interrupted for servicing or there is a failure, the AI controller cannot be set and  
monitored from the system controller.  
• The sensor connected to the AI controller can only be monitored from G(B)-50A Web browser and TG-2000A. The sensor  
cannot be monitored from the G-50A LCD.

Figure 7-1 Example of Connecting the Power Line and M-NET Transmission Line  
Caution:  
• Use a power line and M-NET transmission line that satisfy the specifications described in "6-1. Parts Purchased Separately".  
• Attach a circuit comprising the following components to the supply primary side of the 24 VDC power supply.  
(1) Varistor, (2) Arrester, (3) Noise filter, (4) Fuse  
• It is important to pay attention to the polarity when connecting to the 24 VDC power supply terminal block.  
Connecting the positive and negative in the reverse order will cause a failure.  
• Fix the power line and M-NET transmission line in place on the outside to ensure that the terminal block is not affected by  
any external force.  
Not securely connecting and fixing the wires in place may cause heat generation and fire.  
Make sure that the copper wiring is not short-circuiting the plates (cover, lower case) or neighboring wires.  
Cover the shielded line of the M-NET transmission line with materials such as vinyl tape and prevent short-circuiting with the  
plates.  
Note:  
• If the M-NET transmission line of this device is connected to an M-NET indoor control line and the outdoor unit is down  
because, for example, the power supply is interrupted for servicing or there is a failure, the AI controller cannot be set and  
monitored from the system controller.  
• Be sure to ground this device, PAC-SC50KUA and 24 VDC Power source.  
Measurement accuracy may be affected if devices are not grounded.

7-3. Connecting the Sensors  
For channel 1, select one of the following four types: Pt100 detection, 4 to 20 mADC, 1 to 5 VDC, or 0 to 10 VDC analog  
input.  
• For channel 2, select one of the following three types: 4 to 20 mADC, 1 to 5 VDC, or 0 to 10 VDC analog input.  
• The wire length depends on the specifications of the sensor. However, since the use of long wires makes the device  
susceptible to noise, using wires shorter than 12 m (39.4 ft) is recommended. Use a shielded line for the sensor line  
and connect to the FG terminal on this unit or the FG terminal on the control panel.  
(1) Channel 1 Pt100 Input  
To use these, various settings need to be configured. Refer to "8. Initial Settings".  
Caution:  
• Use a 3-wire system for Pt100.  
B / A / B  
• A/B polarity is important for Pt100.  
Be sure to match the polarity when using Pt100.

11 System Operation Test  
Use the following procedure to confirm operation of the system.  
(1) Configure the settings of this device and the system controller while referring to "8. Initial Settings".  
(2) Confirm whether the measurement values of channel 1 and channel 2 are displayed on the system controller properly.  
* Depending on the conditions, compare the measurement values with those of, for example, a commercially available portable  
thermohygrometer.  
If the measurement accuracy of the sensor used results in extreme differences in the measurement values, use the  
measurement correction value (offset value) input function of the system controller to correct the measurement values.  
(3) When upper/lower limit alarm interlock is to be used, input a value that exceeds the set alarm level and confirm whether the alarm  
is displayed on the controller. Furthermore, confirm whether the alarm output operation takes place from the contact output at the  
same time.  
If there is a problem, check the wiring and settings.  
For details on configuring settings, refer to "8. Initial Settings" and "9. Dip switch functions".

This product is designed and intended for use in the residential,  
commercial and light-industrial environment.  
This product at hand is  
based on the following  
EU regulations:  
• Low Voltage Directive 2006/95/EC  
• Electromagnetic Compatibility Directive  
2004/108/EC  
NOTE:  
This equipment has been tested and found to comply with the limits for a Class  
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed  
to provide reasonable protection against harmful interference in a residential  
installation. This equipment generates, uses and can radiate radio frequency  
energy and, if not installed and used in accordance with the instructions, may  
cause harmful interference to radio communications.  
However, there is no guarantee that interference will not occur in a particular  
installation.  
If this equipment does cause harmful interference to radio or television  
reception, which can be determined by turning the equipment off and on, the  
user is encouraged to try to correct the interference by one or more of the  
following measures:  
- Reorient or relocate the receiving antenna.  
- Increase the separation between the equipment and receiver.  
- Connect the equipment into an outlet on a circuit different from that to which  
the receiver is connected.  
- Consult the dealer or an experienced radio/TV technician for help.
