Safety

Caution

National safety regulations

Failure to comply with national safety regulations may result in personal injury and

property damage.

●Observe national provisions and comply with the appropriate safety regulations.

Mounting

●Do not open the damper actuators

●Do not use the accessory mounting holes for fixation of the damper actuators

Commissioning

Parameterization

The following parameters must be checked or set prior to commissioning:

Parameter Range Description Factory setting

Opening

direction CW (R) / CCW (L) Opening direction of air damper CW (R)

Adaptive

positioning Off / On Adaption of actual opening range to position feedback

Off = No adaption / mapping 0°..90° à0..100 %

On = Pos. adaption / mapping e.g. 0°..60° à0..100 %

Off

Commissioning workflow 1: Full or partial configuration by tool

When using the AST20 handheld tool, all bus and actuator parameters can be set.

●Connect the AST20 to the damper actuator and navigate to the bus configuration menu

●Set bus parameters as desired

●Optionally make changes on actuator parameters.

Note

With AST20, all parameters can beset using the mass configuration function. The bus parameters are included in the

mass configuration function. It can beselected that the address is automatically incremented with each programmed

damper actuator.

Commissioning workflow 2: Configuration over bus (full or partially)

The devices can be configured over bus if the pre-commissioning settings allow for a con-

nection between the Modbus master / programming tool and peripheral devices (i.e. non-

conflicting addresses and matching baudrate / transmission format).

●Full configuration over bus: If the address is unique per segment when powered up, the

device can be accessed by the Modbus master (or programming tool) and the address

and other parameters can then be set to the definitive values.

●Partial configuration over bus: If the address is not unique per segment when powered up,

each device must get a non-conflicting address before connecting it to the bus (e.g. using

the push-button addressing method). After addressing all devices, the remaining configu-

ration can be done over the bus using the default settings for baudrate (auto-baud) and

transmission mode for the Modbus master.

●Overwriting the bus configuration over bus uses a timeout. If „1 = Load“ is not written into

Reg 768 within 30 seconds, all values are discarded.

Example: Table shows bus configuration registers before and after changing them over bus.

Reg. Name Pre-commissioning New value (ex.)

764 MacAddress 46 12

765 Baudrate 0 = auto 1 = 9600

766 Transmission Mode 0 = 1-8-E-1 3 = 1-8-N-2

767 Termination 0 = Off 0 = Off

768 BusConfigCmd 0 = Ready 1 = Load
