Commissioning
Workflow 1
The devices are especially designed for using the Climatix push-button configuration as de-
scribed in document A3975
1)
. The bus configuration can alternatively be parameterized by
the local HMI, cf. page 5.
During commissioning check/set the following:
• Bus configuration (address, baudrate, transmission mode, and optionally termina-
tion). The default address 255 allows to mount and power multiple actuators at the
same time without interfering with each other.
• Damper actuator parameters (opening direction, position limits, position adaptation
etc.) can be checked via the Modbus register.

Workflow 2
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 pow-
ered up, each device must get a non-conflicting address before connecting it to the
bus, either by using the address input with push button (cf. page 7) or by setting the
address to 246 with push button press > 5s und < 10s (cf. page 6). After addressing
all devices, the remaining configuration 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.

Maintenance
The damper actuators are maintenance-free.
Disconnect the electrical connections from the terminals if you want to work at the device.
