Connections

Laser emission control input
This external input short-circuits the yellow and black cables
to stop emission. It is utilized to prevent interference when
driving 2 or more sensor heads alternately, or to stop laser
beam emission in an emergency.
The analogue output voltage just prior to short-circuiting will
be retained.
Laser emission remote control terminals
When the terminals are short-circuited, the LASER ON
alarm LED on the front panel lights and laser emission
begins after 3 seconds. When the terminals are opened,
the LASER ON alarm LED on the front panel turns off and
laser emission stops. For shipping purposes, a short-circuit
bar is inserted between the terminals.
Alarm output (N.C.)
The alarm output is activated when the light quantity
exceeds or falls below a specifi ed limit.
