ABB Module DSQC334 3HAB5845-1 ABB DSQC334 Power Supply Module effective service

Product Description:

In case of a configured plausibility monitoring, range underflow and range overflow by 2...3 % result in an error message (FK4, error number 10).Independent of the configured monitoring, the error values +32767 and -32767 are always generated in case of
range underflow and range overflow. Exception: In the measuring range of 0...20 mA only the range overflow is detected.32760D 7FF8H Further details can be found in volume 2, chapter 5.1 "General information for the use of analog inputs and outputs". In order to make sure, that unused input channels have a defined 0V level, they may be shorted to AGND. Unused inputs must be configured with "unused". The relationship between the analog input signals and the converted numbers is illustrated in the following figures.

Product's Character:

If all of the 8 channels of the group are used as inputs, and if in addition the UP5 terminal is left unconnected, no restrictions exist for the inputs. The input signal voltages then may be within -30 V and 30 V. There is no restriction for the input/output group concerning its safety against reversed polarity.System constants. If no battery is effective or if the system constants are in their default values (factory settings), all of the above mentioned data areas are completely set to 0 after power OFF/ON.  Reactions on errors of error class 3 The user can configure whether or not the user program is to be aborted automatically, if an class 3 error occurs, see chapter B7 (Appendix), System constants.
