9. Error Detection
In order to ensure a maximum of operational safety and reliability, the units are equipped with
several and profound monitoring-functions. The monitoring allows an immediate recognition and
messaging of possible failures and malfunctions.
In case of errors:

The relay contact switches to its open (safety) condition
(interruption of the safety circuit)

The analog output (with DS236 and DS246 units) sets to 0 mA
and no more current range (4 … 20 mA) is given.

All digital outputs are set to LOW (no more inversion between Out X and /Out X)

No more incremental signals are available at the RS422 output (Tri-State with
pulldown cut off).

The DC-offset of the SinCos output will be shifted in order o signalize an error to
the target unit.
The following types of error recognition are distinguished:

Initialization Error

Runtime Error
Both variants are exactly described in the following two pages…
