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