[. . . ] · Turn off the main power supply switch or breaker before attempting any electrical work. Failure to do so may cause electric shock. · Perform installation work properly according to this Installation Manual. Improper installation may result in electric shock or fire. [. . . ] 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 Touch Screen Controller. · 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 18 Grommet for power meter 103. 5 92. 5 (193) Grommet for RS-485 220 18 53. 5 18 246 64. 5 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 DI1 SW1 SW2 SW1 LED2 LED3 LED4 LED5 Address set switch 1-4 Address SW7 DI2 1234 SW2 DI3 DI4 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 SW3 SW4 SW7 LED1 LED2 LED3 LED4 LED5 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. Assign addresses in an ascending order. AB DI8 DI7 DI6 DI5 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. [. . . ] · 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.
