[. . . ] Ask the customer to keep this Installation Manual together with the Owner's Manual. WARNING · Ask an authorized dealer or qualified installation professional to install or reinstall the relay interface. Improper installation may result in electric shock or fire. · Perform installation work properly according to this Installation Manual. Improper installation may result in electric shock or fire. Any modification may cause a malfunction, resulting in overheating or fire. CAUTION · Perform wiring correctly in accordance with the specified current capacity. Failure to do so may result in short-circuiting, overheating, or fire. · Connect the specified cables for the terminals securely to prevent external forces from affecting them. Failure to do so may result in disconnection, overheating, or fire. 1 Introduction nApplications/Functions/Specifications Applications/Functions/Specifications · Applications The Energy Monitoring Relay Interface is used to measure and distribute the power of the air conditioner. · Functions The interface calculates output power pulses with connected power meters, and then sends the calculation result to the Intelligent Server. · Specifications Power supply Power consumption Operating temperature/ humidity Storage temperature Chassis material Dimensions Mass 220 - 240 V, AC 50/60 Hz 2. 8 W 0 to 40°C, 10 to 90% RH -20 to +60°C Galvanized sheet metal 0. 8t 66(H) x 193(W) x 246(D) mm 1. 65 kg Power meter input Input type Input point Input registance Input "ON" current Input pulse condition photo-coupler insulation 8 points 9 k ohm 1 mA 50 m - 1000 m sec External View 234 18 Grommet for power input 103. 5 18 Grommet for power meter 92. 5 (193) Grommet for RS-485 53. 5 64. 5 220 18 18 246 2 63. 6 Before Installation Check the following package contents.

Be careful when connecting the RS-485 wire. CAUTION: No terminator resistor setting switch is provided on the Energy Monitoring Relay Interface. Set the RS-485 terminator resistor on the TCS-NET Relay Interface. 7 RS-485 AB 3 SW4 Setting SW3 ON LED2 LED3 LED4 SW7 DI2 1234 LED5 DI1 SW1 SW2 SW1 SW2 SW3 SW4 SW7 LED1 LED2 LED3 LED4 LED5 Address set switch 1-4 Address 0, 5 - F Not used Operating mode set switch (0 usually) Test switch (all OFF usually) Test switch Reset switch Power indicator RS-485 communication status indicator Not used Test indicator Test indicator N LED1 L RS-485 The following settings are necessary to use Energy Monitoring Relay Interfaces. · SW1 Address set switch When two or more Energy Monitoring Relay Interfaces are used, set a different address for each unit to avoid address duplication. n) AB DI8 DI7 DI6 DI5 DI4 DI3 CAUTION · Set relay interface addresses according to the air conditioner address table. · When the SW1 setting has been changed, push reset switch SW7. · You can set the Energy Monitoring Relay Interface address independently from the TCSNET Relay Interface address or the Digital Input/Output Relay Interface address. · SW2 Operation mode set switch · SW3 Test switch · SW4 Test switch These switches are not used during normal operation. [. . . ] Set zero (0) or "all OFF". · SW7 Reset switch When performing a address setting with SW1, push this reset switch after the address setting to read the set value. 8 4 Trial Operation Check Before starting trial operation Turn on the power of the Energy Monitoring Relay Interface after all wire connections and settings are completed. Turn on power of the air conditioning control system. Trial operation · Confirming connection to power meters In the test mode, when the external inputs connected to the input terminals DI-1 to DI-8 are ON, the respective LEDs will goes on so you can confirm the connection. Confirming procedure: Set the operation mode switch SW2 to "3", and push the reset switch SW7 to enter the test mode. Unless SW4 is pushed, respective input status of DI-1 to DI-4 is indicated by LED2 to LED5. [. . . ]
