5.2 Acknowledgment of error messages
Potential fault sources can be determined by checking the indications and
flashing frequencies of the RUN and Error LEDs and using tables 18 to 21.
Once the source of a fault has been fixed or eliminated, a restart can be
carried out.
Certain error messages can be acknowledged during operation if
• The control signal on terminal +A1 is switched off and then back on
• The corresponding bits are set again if SmartWire-DT-based control is
being used
