WARNING
There is a risk of death or serious injury if the stopping distance is calculated incor‐
rectly.
b
The default setting for the Speed Filter parameter is 10 mm and this must be
taken into account at the planning stage (
).
b
This value must not be changed.
As this is not a time-based filter, this function does not increase the response time.
Instead, the stopping distance will increase if there is a fault. The stopping distance is
increased accordingly with the default setting of 10 mm. This must be considered when
calculating the stopping distance.

Configuring position ranges
WARNING
There is a risk of death or serious injury as diagnostics for the protective device are not
reliable.
Value range monitoring is implemented in the safety system so that diagnostics can be
performed. For this reason, the minimum and maximum values of the bar code tape in
use should be configured at the configuration stage. 0 is not permitted as a minimum
value.

Figure 9: Position Ranges with sample values
The full position range for the application needs to be configured. The following should
be noted here:
•
Only the position range that is actually being used within the application should be
configured. In the example shown, only one bar code tape should be used from
the 100 mm position to 15,000 mm.
•
Ranges requiring a safely limited speed to be monitored must be defined.
