STATUS INDICATOR LED
The M2XU is provided with a status indicator LED which
blinks in different patterns indicating various status of its
CPU.
When it is functioning within normal parameters, the LED
blinks in a regular pattern of ON and OFF.
When the unit is in an abnormality, it blinks in particular
patterns repeating approximately in 1.3 seconds.
The following figure indicates typical patterns. A white
circle means that the light is OFF for 80 millisec., while a
black one means ON for 80 millisec.

50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out
of tolerance, recalibrate the unit according to the “HARD-
WARE ADJUSTMENT” explained earlier.
