To reduce the risk of fire and electric shock, do not install the units where they may get wet. To reduce the risk of electric shock, fire and malfunction, the unit must not be installed in a steamy or condensing location. To reduce the risk of electrical leakage, overheating and fire, use only standard cables with the correct current carrying capacity.
To reduce the risk of electric shock and malfunction, keep wire pieces and sheath chips out of the terminal block. To reduce the risk of electric shock, fire or malfunction, do not wash the device with water or other types of liquids. To reduce the risk of electric shock, wear protective gloves before touching the electrical parts of the device.
To reduce the risk of electric shock, turn off the power before performing electrical work. To reduce the risk of injury from accidentally dropped tools, check the area and keep children out of the area before installation, inspection and repair.
-YG50ECA has a built-in function to supply power to the M-NET transmission line. power coefficient: 6) When power is supplied by the PAC-YG50ECA, the system controller types shown in the table below can be connected. Note When the PAC-YG50ECA is connected to the M-NET system, the AG-150A/G(B)-50A cannot be connected to the same M-NET system.
Assign an address equal to the address of the outdoor unit in the same refrigerant. Assign an arbitrary but unused address to the controller after the address setting for the units is completed with an address between 1 and 50. -YG60MCA) Assign an arbitrary but unused address to the controller after the address is completed. setting for the units with an address between 1 and 50. PAC.
-YG63MCA) After entering the address, assign any but unused address to the controller. -control indoor unit First assign an address to all indoor units connected to the M-NET lines (including LOSSNAY units), then assign addresses to the K-control indoor units starting with. address after the last address. controller Specify the address as the lowest address of K-control indoor units in the same.
Refer to the installation manual of the outdoor unit for detailed information about the dip switch settings.). The K-control Y series units and other types of units cannot be connected to the same transmission line.
Connect the PAC-YG50ECA to the central control transmission line (TB7 on the outdoor unit). Maximum power supply distance is the distance at which a power supply unit (or an outdoor unit designated as a power supply unit) is able to supply power to other devices on the receiving end, such as remote controls and indoor units. 2 If the ME remote control cord length ( 3, 8) is 10 m (32 ft) or less, it does not need to be included in the maximum distance to the farthest unit.
Leave enough space around the unit as shown in the figure below to allow you to install/remove the cover and wiring. Make sure you install the unit in a place where there is no chance of dew condensation. Unscrew the two screws on the cover to remove it, as shown in the image below.
Connect the power cable and the protective earth cable as shown in the figure below. Use an M3.5 ring terminal to the power cable and an M4 ring terminal to the protective earth cable before connecting them to their corresponding terminals (power supply terminal block or protective earth terminal).
CAUTION • In an air conditioner system with more than 1 outdoor unit, the system controller receiving transmission power through TB7 on one of the outdoor units would run the risk that a failure of the connected outdoor units would stop power supply to the system controller and disrupt the entire system. . 1 Insulate the cables with vinyl tape, except the part that connects to the ring terminal. NOTE • Connect the PAC-YG50ECA power jumper to CN41 (does not supply power).
Do not connect more than four devices (gateway, router, layer 3 switch, HUB, etc.) in series between AG-150A and PAC-YG50ECA. The transmission delay time should not exceed 2 seconds.). CAUTION • Install the LAN cable before installing the unit and route the cable in the same way as the M-NET transmission lines. Leave enough space around the LAN port on the PAC-YG50ECA to allow the connector and cables to be attached.
Refer to the AG-150A instruction manual, technical manual, and other related manuals for detailed information on initial settings and operating modes.
Quick IP address setting switches (SW602) must be set to "ALL OFF" to make these settings. Contact your network administrator for how to set the IP address, subnet mask, and gateway address when connecting the expansion controller to an existing LAN. Note If fifteen or fewer expansion controllers are connected to a dedicated network, it is recommended that the IP address be set with SW602 on the PAC-YG50ECA.
Turn all SW602 OFF before setting the IP addresses with the detailed setting switch (see Section 5-1-2). If fifteen or fewer expansion controllers are connected to the dedicated network, it is recommended that the IP address be set from SW602 to PAC-YG50ECA. Important Before installing the unit, install the LAN cable and route it in the same way as the M-NET transmission lines.
Do not connect more than four devices (gateway, router, layer 3 switch, HUB, etc.) between AG-150A and PAC-YG50ECA in series. Set this switch to prohibit operation from both the subsystem controller and the remote OR only the remote. External Input Mode (Set from AG-150A or other controllers) Set the external input mode.
Factory setting) OFF Allows connection of AG-150A and other controllers (At the end of a test) Does not allow connection of AG-150A and other controllers ON. LD5 will be lit if group setting and lock setting by AG-150A and other controllers are not completed. 6 Check each unit for proper operation (eg, supply air comes out of the indoor unit plug.).
7 Turn SW603-2 from OFF to ON to stop the units. 1 Fault LED and LD4 will not light/flash when the AG-150A or other controller is in fault.
Designates a system controller within the system as the only controller from which operation ban setting can be made. When making the group setting for K control units, make the setting only for the indoor units that belong to a given group. The group number given to a group of K control units must be the same as the lowest address of the indoor units belonging to the group.
If the K-control Y series units and other types of units (K-control Mr. Slim) are used in combination, a relay board is required. The K-control Y-series units cannot be connected to the same transmission lines as the other types of units. Depending on the number of K control units and transmission line length, a relay board may be required.
Remote control addresses do not need to be included in the group setting for a group of K control units.
