0.1 ... 100.0
Use this sub-parameter to set a base limit in percent. The base limit
defines the magnitude of the permissible deviation from the expec‐
ted position course. The limit serves as a reference variable for the
fault message factors.
Set the base limit in a range from '0.1' to '100.0'.
1.0
0.1 ... 100.0
Use this sub-parameter to set the factor for formation of threshold
1. Set the factor in a range from '0.1' to '100.0'. The threshold is the
product of 'b2.LIMIT' and 'b3.FACT1'.
The threshold 1 message is displayed when threshold 1 is excee‐
ded. This message is only output if threshold 2 or 3 is not exceeded
at the same time. The process to activate and display this message
is described in the 'XDIAG' parameter.
5.0
0.1 ... 100.0
Use this sub-parameter to set the factor for formation of threshold
1. Set the factor in a range from '0.1' to '100.0'. The threshold is the
product of 'b2.LIMIT' and 'b4.FACT2'.
The threshold 2 message is displayed when threshold 2 is excee‐
ded. This message is only output if threshold 3 is not exceeded at
the same time. The process to activate and display this message is
described in the 'XDIAG' parameter.
10.0
0.1 ... 100.0
Use this sub-parameter to set the factor for formation of threshold
1. Set the factor in a range from '0.1' to '100.0'. The threshold is the
product of 'b2.LIMIT' and 'b5.FACT3'.
The threshold 3 message is displayed when threshold 3 is excee‐
ded. The process to activate and display this message is described
in the 'XDIAG' parameter.
