Notes
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.
Commissioning
The devices were developed specifically for use with Climatix pushbutton configuration as
described in document CE1A3975
1)
.
The bus configuration can alternatively be configured by the local HMI, see section User
interface [➙ 4]
Check the following during commissioning:
● Bus configuration (address, baudrate, transmission mode, and optional bus termination).
The default address 255 allows mounting and commissioning of multiple actuators at the
same time without interfering with each other.
● Actuator parameters (Opening direction, position limits, position adaptation, etc.). The
value can be read over the Modbus register.

Full or partial configuration via bus
The devices can be configured over bus if the pre-commissioning settings allow for a
connection between the Modbus master / programming tool and peripheral devices (i.e. non-
conflicting addresses and matching baudrate / transmission format).
● Full configuration via bus: A unique Modbus address can connect by the Modbus
master/programming tool after startup using the presets for transmission format and
baud rate (or auto-baud).
● Partial configuration over the bus: A Modbus address that is not unique must be first set
to a unique address, either by using the address input with pushbutton (see Enter
address using pushbutton [➙ 5]) or by setting the address to 246 by pressing the
pushbutton > 5s and < 10s (see Pushbutton operation [➙ 4]). The Modbus
master/programming tool can then connect after startup using the the presets for
transmission format and baud rate (or auto-baud).
The bus and actuator parameters can be set to target values on an existing connection over
the bus. For write operations to the bus parameters, "1 = Load" must be written to Reg 768
within 30 seconds; the changes are otherwise discarded.
Example: The table shows the register values before and after the change via bus access.
Tabs Name Before change After change
764 Modbus address 246 12
765 Baud rate 0 = Auto 1 = 9600
766 Transmission format 0 = 1-8-E-1 3 = 1-8-N-2
767 Bus termination 0 = Off 0 = Off
768 Bus conf. command 0 = Ready 1 = Load
