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

1.2.1 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.

1.2.2 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).

1.2.3 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

1.3.1 Operating Environment

Avoid assembling the EC-FAN GATEWAY controller in environments with the following characteristics• Relative humidity greater than 90%

• Strong vibrations or knocks


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

1.3.2 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.

6. INSTALLATION

6.1 User Interface and LED Buttons

Fig. 4 LED Indicators

pCOWeb (Figure 3) features a button (PUSHBUTTON) and two indicator LEDs (STATUS LED and ETHERNET LED).

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 7.5.

6.3 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.

6.4 Addressing fans• Before the set up of the EC-FAN GATEWAY the number of active ebm-papst fans that are to be connected to the EC-

FAN GATEWAY will have to be pre-programmed via EC-Control. EC-Control is to be used to assign addresses for the respective fans.

• The EC-FAN GATEWAY will not automatically assign addresses to the fans that are required on its network.

• ebm-papst recommends that the first fan be programmed at address 2 and the following fans thereafter to be programmed at “n+1”. This is to avoid any confusion when a new fan unit is to be added to an existing network. ebm-papst fans are by factory default addressed 1.

• Ensure that the fans are not connected to the EC-FAN GATEWAY before the device has been appropriately programmed. Power down the fans. Attach the communication cables to point 2 as per fig. 3 and power up the fans.

Figure 20 describes the “Read and Write” type variables for the first MODBUS fan (Fan 1) in an installation. Take note that each MODBUS fan has 30 registers assigned on the EC-Fan Gateway device.

Please apply the formula found under Register Number Fan (X) to determine the appropriate register number for the different variables that represent Fan2,3 … 31. For example, if you were to change the “Ramp Up” time on Fan 2 then you will be writing a value at register 43 (30(2-1)+13 = 43). Subsequently, the “Ramp Up” time for Fan 3 is assigned to register 73.

Take note that if the address is changed digitally via the building management system, this address change will also have to be implemented on the EC-Fan Gateway device.

Once the above steps are completed your EC-FAN GATEWAY has been successfully set up. If you have further questions please contact your ebm-papst representative or your nearest ebm-papst office.
