The detector cold started on power
up. Default values were used for
calibration settings.
Possible causes:
Table Cold start DIP Switch is set to
ON
Table Memory checksum problem
E 2 RESETDIS
The reset disable input is open.
(This input is used for the optional
marker feature.)
You cannot reset the detector until
the input is closed by resetting the
marker. (This prevents you from
restarting the belt without the
marker in place.)
