7. Error Output
An HTL error signal is available on the X3 screw terminal 1. (Error = Low).
The error (short circuit or line break) is triggered by the input lines A, /A, B, /B or Z,
/Z (Test mode OFF, DIL2/2 = OFF). The corresponding channel can be selected with
the DIL switch DIL3 (right, 3-pole).
If the DIL switch DIL3/1 is set to OFF, no errors are evaluated on the A, /A line, the
DIL switch DIL3/2 refers to the line B, /B and the DIL switch DIL3/3 to the line Z, /Z.
An error can only be detected in RS-422 or HTL differential format, all other formats
do not trigger an error.
