ON corre-
sponds to the measurement initiation in the SINAUT LSA.
An abort of the measuring phase is initiated via
´!6\0HDVµ
OFF.
• Control: This phase executes the control subfunction.
The command procedure is aborted for:
– Abort command with AC+
– Monitoring time exceeded

ON, synchronisation failed with CO-
The command procedure is started via the following indication:
–
´6\QF&ORVH5HOµ
