ABB i-bus Device Technology Supplied state The device is supplied with the physical address 15.15.255. The application program is preloaded. It is therefore only necessary to load group addresses and parameters during commissioning. However, the complete application program can be reloaded if required. A longer downtime may result if the application program is changed or after a discharge.
ABB i-bus Device Technology Manual operation General The outputs can be directly controlled using the buttons in manual operation. Accordingly, the wiring of the loads connected to the outputs can be verified during commissioning. You can, for example, ensure that the connected valve drives open or close the valves correctly. If bus voltage is not yet available at the time of commissioning, the device can be supplied with power for manual operation using the Power Supply NTI/Z.
ABB i-bus Device Technology 2.5.1 Display elements Indicator LEDs are located on the front of the device. All LEDs Output X indicate the actual state. In KNX operation the LED is off. The response of the display elements is described in the following table:...
ABB i-bus Device Technology 2.5.2 Operating controls Buttons for manual operation are located on the front of the device. If manual operation is activated, the current control value of the respective output is retained and the yellow LEDs on the outputs indicate the current status (ON/OFF). A target position, which may not have yet been achieved, is approached.
Commissioning Commissioning ® The ABB i-bus KNX Valve Drive Actuators VAA/S x.230.2.1 are actuators for control of electrothermal valve drives for room temperature control. The outputs each feature the same range of functions, whereby each output can be parameterized individually.
Note When the term “channels” is used in the ETS, inputs and/or outputs are meant. In order to ensure that ® the ETS language generally applies for as many ABB i-bus devices as possible, the word channels is used here.
ABB i-bus Commissioning 3.1.1.1 Procedure Insert the required device into the project. Import the current application program into the ETS. Perform parameterization and program the device. After you have parameterized a device, you can transfer the settings to a second device.

Parameters Programming of the Valve Drive Actuator is implemented with the Engineering Tool Software (ETS). The application program is available in the ETS3 at ABB/Heating, Ventilation, Air conditioning/Valve Drive Actuator. The following chapter describes the parameters of the device using the parameter window. The parameter window features a dynamic structure, so that further parameters may be enabled depending on the parameterization and the function.

Send communication object “In operation” Options: send value 0 cyclically send value 1 cyclically The communication object In operation (no. 0) indicates the presence of the device on the bus. This cyclic telegram can be monitored by an external device.

ABB i-bus Planning and Application Reaction of the output after negative short-circuit test (no short circuit test) If a short circuit could not be determined after the fuse trips and the three outputs are tested, after about 40 seconds the 3 outputs of a group are checked for a possible overload. A 7 day test cycle commences.
ABB i-bus Planning and Application Bus voltage recovery General A control value can be predefined at bus voltage recovery. The corresponding communication object values are set, see Table page 50. Time-dependent functions are non-functional and must be restarted, e.g. valve purge.
ABB i-bus Planning and Application Bus voltage failure The device can no longer be controlled at a bus voltage failure. The outputs switch off and the valve drives assume their position in a no-current state (open or closed). Manual operation is not possible during a bus voltage failure.
