If condensation occurs at the mounting site, the use of the temperature adapter ALJ100 is
recommended in order to protect the actuator. If the medium temperature is ≤ 0 °C, the

Commissioning
arameterization
The following parameters must be checked or set prior to commissioning:
arameter Range Description Factory setting
Opening
direction
CW (R) / CCW (L) Opening direction of rotar actuator CW (R)
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 rotar actuator and navigate to the bus configuration menu
● Set bus parameters as desired
● Optionall make changes on actuator parameters.
Note
With AST20, all parameters can be set using the mass configuration function. The bus parameters are included in the
mass configuration function. It can be selected that the address is automaticall incremented with each programmed
actuator.
Commissioning workflow 2: Configuration over bus (fully 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 b 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 re-commissioning New value (ex.)
764 MacAddress 46 12
