Operating Instructions ACU
16.3.8 Warning mask
The warning mask signals, via a digital signal, if a pre-configured warning is present. The warning
mask is configured via Create Warning Mask 536. Warnings and controller status messages can be
combined. This enables internal or external control using a common output signal. The display of
269 Warning and 275 Controller Status is not influenced via the warning mask.
Select one of the settings 1 … 43 to activate messages.
Select one of the Operation Modes 101 … 143, if certain warnings are not to be reported.
Configured warning mask is not modified.
The warnings and controller status messages stated are linked in
the warning mask.
