19.1 General
An alarm is identified by two numbers separated by a dot (Y.X).
The first part (Y) is the source of the alarm, and the second (X) is the issue (e.g. overcurrent).
In addition to the ID, an active alarm also has a location that identifies where on the machine the problem is, which may either be a general addressing number, a device number or a textual description.
Yellow marking means Warning.
Operation of the machine may continue, but the error condition should be remedied as quickly as possible. The machine is operated with limited function.
Red marking means Critical.
The machine should not be driven any further. Remedy the fault immediately or choose to override the alarm knowing that the machine is not fully functional or can be damaged.
