STATUS INDICATOR LED
The CPU status is indicated by different blinking patterns of the front
indicator LED. 1 pattern cycle is divided in 16 ON or OFF periods, each of
which lasts for 320 millisec.
In the figure to the right,
it is ON. The ON-OFF pattern changes from the left end to the right in 320
millisec. duration.
There are more of these patterns which are not shown here, however, when
the last one shown in the figure to the right or some other pattern is
indicated, contact M-System.
The anomaly report is available also on the display of the Programming
Unit. Refer to its manual for detailed information.
