[. . . ] · 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 specified the 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 Digital Input/Output Relay Interface is used to control air conditioners by interlocking them with electric lock signals and fire alarm signals, and to transmit air conditioner failures to other devices. · Functions The Digital Input/Output Relay Interface connects non-voltage contact signals, transmits their input status to the Intelligent Server, and outputs signals from the contacts (open collector) according to the command from the Intelligent Server. · Specifications Power supply Power consumption Operating temperature/ humidity Storage temperature Chassis material Dimensions Mass 220 - 240 V, AC 50/60 Hz 6. 5 W 0 to 40 °C, 10 to 90% RH -20 to +60 °C Galvanized sheet metal 0. 8t (no coating) 66(H) x 193(W) x 246(D) mm 1. 65 kg Digital input Input type Input points Input registance Input "ON" current Output type Output points Output current Output voltage Photo-coupler insulation 8 points 9 k ohm 1 mA Open collector 4 points Max. 35 mA (per point) Less than DC 24V DC 12 V, 120 mA Digital output External power supply for Input/Output External View 234 18 Grommet for power input 103. 5 18 Grommet for Digital Inputs 92. 5 (193) Grommet for RS485 53. 5 64. 5 18 220 18 Grommet for Digital Outputs 246 2 63. 6 66 Before Installation Check the following package contents.

Assign addresses in ascending order. 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 the reset switch SW7. · SW2 · SW3 · SW4 · SW7 Operation mode set switch These switches are not used during normal Test switch operation. Test switch Reset switch When performing address setting with SW1, push this reset switch after address setting to read the set value. 8 4 Trial Operation Check Before starting trial operation Turn on the power of the Digital Input/Output Relay Interface after all cable connections and settings are completed. Turn on power of the air conditioning control system. Trial operation · Confirming external input connection 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, the respective input status of DI-1 to DI-4 is indicated by LED2 to LED5. When SW4 is pushed, the respective input status of DI-5 to DI-8 is indicated by LED2 to LED5. [. . . ] When SW4 is pushed, the respective input status of DI-5 to DI-8 is indicated by LED2 to LED5. (*) To return to the normal operation, reset SW2 to "zero (0)" and push SW7. SW4 OFF SW4 ON LED2 Displays DI-1 input status. Input ON: LED lights Input OFF: LED turns off LED4 Displays DI-3 input status. Displays DI-8 input status. · Checking external output connection In the test mode, you can set output terminals DO1 to DO4 to ON or OFF with the test switch. [. . . ]
