Diagnostics and Troubleshooting
Superlight VI Safety Light Curtain
between Emitter and Receiver pylons
is broken. The light curtain will either
display a code "C" upon power up, or
stay in a RED condition.
Test: Run troubled light curtain with other
light curtains (in view) turned off. The
troubled light curtain should now work
correctly.
Cure(s): a) Try re-adjusting the locations of all
light curtains. A slight tilt of a pylon
can clear up the problem.
b) Put up partitions or blinders
between light curtains.
PROBLEM: Light curtain does not go GREEN.
Cause(s): Many.
Test: Try running the unit with the pylons
butted up against each other. The unit
should now go GREEN. If it doesn't,
the unit should be returned for repair.
If it went GREEN, the beams may be
mis-aligned. You may be running the
unit beyond its aligned distance. There
is a 5% penalty for every mirror you
use.
Cures: Both pylons ma y require slight
a djustments even a fter b eing
mechanically aligned to get the unit
to go GREEN. The SuperLight VI
system uses infrared light emitting
diodes {IRLED's) as a means of
detecting obstructions found in the
field of view between the two pylons.
These IRLED's are spaced at regular
intervals down the entire length of the
curtain. The infrared light fans out
like a flashlight beam, not like a laser
beam. As the infrared light fans out, it
loses strength, so the farther apart the
light curtain pylons are, the weaker the
signal. Proper mechanical alignment
of the pylons should allow the light
curtain to function properly. However,
some problems can still occur, but can
be cleared up upon further explanation.
They are as follows:
Connections. Check for proper
connections and voltage levels before
proceeding further.

Vibration.
The SuperLight VI system
allows for a certain amount of
mechanical play once aligned, but
sometimes the units are installed so
movement in a particular direction
will cause the unit to go RED. Over a
period of time, vibration may cause the
mounting brackets to shift slightly and
in some cases the unit may become
misaligned to the point that it will not go
GREEN anymore. To determine this,
loosen up the mounts and re-adjust
both pylons one at a time until the unit
goes GREEN. If you have mirrors, you
may have to re-adjust them too.
Obstructions: Look for objects that are
close to or in the field of view of the light
curtain. Once you have determined a
location to mount your light curtain, you
must be careful of nearby obstructions
(objects that are not mechanically in the
line of sight of the light curtain pylons
but fall within about 1/2 inch). Although
these objects may not be mechanically
in the line of sight, the light curtain may
fail to go GREEN because it detected
the object as an obstruction. The
reason for this is because the nearby
obstruction reduces the amount of
infrared light that gets by the object
and the Receiver Pylon fails to see the
beam and stays RED.
Use of Mirrors. The use of mirrors to
go around corners creates a penalty in
distance and adjustment play. When
you use mirrors, some of the infrared
light passes through the surface
coating of the mirror. This decreases
the total distance the light curtain can
go (about 5% per mirror). If the mirror
was not surface coated, the loss would
be even greater and parallax view
would make it very difficult to align.
Upon determining the location of the
mirrors, you must allow for some
adjustment. Because angle of
incidence equals angle of reflection, a
small error in location of any mirror will
throw off the beams as they pass to the
next mirror and may be compounded
when passed again to a third mirror.
Even though you may have determined
that mechanically the beams should
