Function blocks
Figure 1 shows the function-related block structure, and Figure 2 shows the hardware-related block structure. The
significance and use of the illustrated inputs and outputs is explained in tables 1-3.

2.4. Operation statuses
The enabled operation status is visible to the user on the content of the 7-segment readout.
2.4.1. Initialisation
Temporary state after switching on the operating voltage. All test routines must be performed at least once. Normal
operation is only resumed once the system is free of any faults.
Normal state
All test routines to determine any internal and external faults are performed in a cyclical manner. If a fault is
detected, then the system immediately switches to fault mode.
The safety output states are continuously calculated based on the parameter data and input information and
switched to the assigned terminals if the system is free of any faults.
In order to optimise the monitoring configuration, the user can enable parameter input and make the required
settings at any time. If the amended parameters are not suitable for the configuration, then the system switches to
fault mode.
Parameter input
All safety outputs are destaged during parameter input. The user is free to amend the configuration. The amended
configuration is enabled as soon as it is saved, and it then automatically returns to normal mode.
Fault mode
The safety outputs are destaged. This mode can only be exited by resetting after debugging, depending on the
fault category.
If it is necessary to amend the parameters for debugging purposes, then the user can also enable parameter input
when in fault mode as well.
