5.9 Operation and conguration of the control unit
The service buttons can be used to operate the controller.
The following options are available to parameterize the controller.
1. Parameter assignment via the eldbus PKW interface
2. Parameter assignment with the terminal module
3. Parameter assignment via supplementary devices (SIDOOR SERVICE TOOL, SIDOOR 
SOFTWARE KIT)
WARNING
Verify parameters.
In the case of parameter assignment via the SIDOOR SOFTWARE KIT or via the eldbus PKW 
interface, parameter values must be read back and veried after modication.
WARNING
Access protection to the controllers/parameters.
Access to the controller and the parameter assignment of the controller must be protected 
against unauthorized access. Appropriate measures must be taken for specic applications, 
e.g. installation in a closed control cabinet, to ensure access only by authorized personnel. 
WARNING
Verication of safety-related functions
The SIDOOR controller is only a subsystem (incomplete machine). In general, the correct 
parameter assignment of the SIDOOR controller and the eectiveness of the safety-related 
functions must be checked at regular intervals by testing the safety-related functions during 
commissioning and depending on the application.
Note
ATD401W Detecting parameter changes 
For the SIDOOR ATD401W controller the checksums of the parameters have to be checked as 
part of the maintenance intervals. This allows changes of parameters to be detected. The 
checksums of the parameters can be requested via the service menu "Service menu -> 
Checksums".
Note
ATD420W / ATD430W Detecting parameter changes 
The checksums of the parameters for controllers SIDOOR ATD420W und ATD430W have to be 
monitored cyclically through a higher-level control. This way changes to parameters can be 
detected. The checksums of the parameters can be requested via the parameters r200 and r201.
