3 1. INTRODUCTION The EC-FAN GATEWAY is a user configurable BACnet protocol communications gateway that provides a bridging platform for information flow between BACnet and MODBUS protocols. This smart device is a simple to use controller that can be applied to managing HVAC applications, but above all a special accessory for the connectivity of all MODBUS protocol ebm-papst fans to the most commonly used building management system, BACnet. The program and its parameters are saved to FLASH memory and EEPROM. This results in the EC-FAN GATEWAY retaining programmable data irrespective of any power failures and thus eliminates the requirement of a back up battery. The program can be loaded via PC. 1.1 Installation Mechanical Fastening The EC-FAN GATEWAY is installed on a DIN rail. To fasten the unit to the DIN rail, press it lightly against the rail. The rear tabs will click into place, locking the unit to the rail. Removing the rail is just as simple, using a screwdriver through the release slot to lever and lift the tabs. The tabs are kept in the locked positions by the springs. Note that DIN rail is not provided in the scope of delivery. 1.2 Power Supply AC The power supply is connected between G and G0 (Cf. Figure 1a). For AC installation, it is recommended to use a 30 VA class 2 safety transformer that provides an output voltage of 24 Vac. This is to supply a single EC-FAN GATEWAY only. When supplying multiple EC-FAN GATEWAY controllers with the same transformer, the transformer s rated power must be n x 30VA, where n represents the number of EC-FAN GATEWAY controllers being supplied by this transformer DC The power supply is connected between G and G0 (Cf. Figure 1b). The voltage supply required is 48 Vdc (36V min to 72V max) Fuse The power supply to the EC-FAN GATEWAY and terminal (or series of EC-FAN GATEWAYs and terminals) should be separate from the power supply to the other electrical devices (contactors and other electromechanical components) inside the electrical panel. A 250 V 800 mat fuse must be installed in the power supply line. The power supply is functionally insulated from the rest of the I/O circuit, including the serial connections. 1.3 Installation warnings Operating Environment Avoid assembling the EC-FAN GATEWAY controller in environments with the following characteristics Relative humidity greater than 90% Strong vibrations or knocks 3

4 Exposure to continuous water sprays Exposure to corrosive or pollutant gases (eg. sulphur or ammonia fumes, saline mist, smoke). This is to avoid corrosion and oxidation of the controller unit Strong magnetic and/or radio interference. Avoid installation of the EC-FAN GATEWAY close to transmitting antennas Large and rapid ambient temperature fluctuations Environments where explosive mixes of flammable gases are present Exposure to dust Connecting the EC-FAN GATEWAY Using an inappropriate power supply from the one specified could seriously damage the EC-FAN GATEWAY. Use cable ends that are suitable for the terminals. Loosen each screw and insert the cable ends, then tighten the screws once completed, lightly tug at the cables to ensure that they are appropriately fitted. Avoid touching or coming into close contact with the electronic components fitted on the boards. This is recommended to avoid electrostatic discharges from the operator to the components. Electrostatic discharges can have an extremely detrimental effect on the functionality of the EC-FAN GATEWAY. Disconnect the controller from the power supply before performing any maintenance or assembly connections/operations. If and when the EC-FAN GATEWAY is not used in the manner specified by the manufacturer, the rated protection of the device may be compromised. 2.

7 5. ACCESSORIES ECGA-001, BACnet MS/TP RS485 serial card 6. INSTALLATION 6.1 User Interface and LED Buttons pcoweb (Figure 3) features a button (PUSHBUTTON) and two indicator LEDs (STATUS LED and ETHERNET LED). Fig. 4 LED Indicators Functions of the button When starting up the pcoweb, the push button is used to select the network communication type - either factory parameters or user parameters. In the case of the EC-FAN GATEWAY the parameters have already been pre-programmed for the customer. There is no requirement for the customer to select network communication. 6.2 Push button & LEDs When the Ethernet LED is in a solid green state, this indicates successful connectivity between the PC and the EC-FAN GATEWAY. When the status LED is green, this indicateds successul communication between PC (pcoweb software) and the EC-FAN GATEWAY. Immediately after reboot, as soon as the Status LED remains on steady GREEN, hold the button; after around 20 seconds the Status LED will turn RED and flash slowly 3 times. The button must be released before the end of the 3 flashes. This process has to be done only once at the point of programming the device. In normal operation, the push button reboots pcoweb without needing to disconnect the power supply. The customer is not recommended to reboot the system via the push button as this is done by the pcoweb webpage that is to be set up in Section Connection Connect pcoweb to the Ethernet connector on the PC using a crossover cable (Figure 4). Please note that the crossover cable is not part of the scope of delivery. Fig. 5 pcoweb to PC connection 7
