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.
1) The documents can be downloaded from http://siemens.com/bt/download
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 6) or by setting the
address to 246 with push button press > 5s und < 10s (cf. page 5). 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.
Reg. Name Pre-commissioning New value (ex.)
764 Modbus Address 246 12
765 Baudrate 0 = auto 1 = 9600
766 Transmission Format 0 = 1-8-E-1 3 = 1-8-N-2
767 Termination 0 = Off 0 = Off
768 Bus Conf. Command 0 = Ready 1 = Load
Maintenance
The damper actuators are maintenance-free.
Disconnect the electrical connections from the terminals if you want to work at the device.
Disposal
The device is considered an electronics device for disposal in terms of Euro-
pean Directive 2012/19/EU and may not be disposed of as domestic garbage.
∂Dispose of the device through channels provided for this purpose.
∂Comply with all local and currently applicable laws and regulations.
Warranty
Technical data on specific applications are valid only together with Siemens products listed
under "Equipment combinations". Siemens rejects any and all warranties in the event that
third-party products are used.

Resetting the device by push button
1. Press button for >10s ⇓LED starts flashing orange
2. Release button while LED still flashes ⇓LED keeps flashing for 3s
3. If the button is pressed within these 3s, the reset is cancelled.
4. After those 3s ⇓LED shines red (reset), then the device restarts.
Push-button addressing
Display current address (starting with lowest address digit)
The Modbus address can be set without a separate tool by using the push-button and LED.
To display the current address, press button <1s.
Colors
1-digits: red 10-digits: green 100-digits: orange
Example for address 124:
LED
Note
The address is entered and shown starting with lowest
address digit, see figure above.
(124 in the example is starting with 4x red)
Set new address (starting with lowest address digit)
1. Enter addressing mode: press button > 1s until LED shines red, then release button
(before LED gets dark).
2. Enter digits: press button n-times ⇓LED flashes per button press (feedback).
Colors: 1-digits: red / 10-digits: green / 100-digits: orange
3. Store digits: press button until LED shines in color of following digits – release button,
4. Save address: press button until LED shines red (confirmation) ⇓release button.
An address can be stored at any time, i.e. after setting the 1-digits, or after setting the 1-
and the 10-digits.
5. Entered address is repeated one times for confirmation.
Note: If button is released before LED shines red, the address is discarded.
