fault signal-
Fault signal output -
When there is some fault, ports 7 and 20 will
be short-circuited. The maximum
short-circuit current here should not exceed
1A. Please add the series resistance according
to the actual operating condition; when the
laser works well, ports 7 and 20 will be
open-circuited.
