Diagnostic Indicator Lights
Emitter Pylon. The Sync Channel light is located on
the Emitter Pylon and is visible 11 1 /2 inches down
from the top of the enclosure inside the pylon (it cannot
be viewed from outside the pylon, the cover must be
taken off). The normal condition of this light is out. It
will illuminate only if the top channel is blocked or not
lined up, and briefly for a 1 /2 second at the time power
is applied to both pylons.
There are internal indicator lights located inside at
the top of the Emitter Pylon to indicate proper internal
voltages. These are:
1) GREEN - 15VDC D19
2) RED +15VDC D18
3) AMBER + 10VDC D17
All three lights must be illuminated for proper system
operation.
Receiver Pylon. There are internal indicator lights
located inside near the top of the Receiver Pylon on the
upper printed circuit board, lower right side, to indicate
proper internal voltages. These are:
1) GREEN
2) RED
3) AMBER
-15VDC
+ 15VDC
+5VDC D22
D21
D20
All three lights must be illuminated for proper system
operation.
Slave Microprocessor. Four more LED's are located
inside at the very top of the upper printed circuit board
in the Receiver Pylon, these indicators explain the
condition of the Slave Microprocessor. These are:
1) GREEN OK
2) YELLOW Blocked DATA CHANNEL
3) RED External fault (slave
detected a fault)
4) RED
Internal fault (slave
microprocessor is bad)
You may notice flickering in these LED's, this is because
the slave is much faster than the system it is monitoring.
If either RED LED stays lit, then a fault occurred and
the unit must be checked out.
Diagnostics and Troubleshooting
Superlight VI Safety Light Curtain

Troubleshooting
NOTE: When light curtain is powered up, the Diagnostics
Display will count down four times with the decimal
points on. This indicates that the microprocessors are
functioning correctly. If you do not see this happening,
your light curtain unit must be returned for repair.
PROBLEM: Light curtain locks up/ light curtain
resets when penetrated.
Cause(s): 1) Check line voltage on the input
power terminals and make sure that
it is within this units' specifications.
Low voltage can keep the output
relays from closing and will keep
the guard in a RED condition and/
or cause the microprocessors to
keep resetting.
2) Check the voltage level on the
output relay contact terminals-it
should not exceed 130VAC. A
higher voltage will cause the
internal MOV noise filtering devices
to short to ground when the output
relay contacts close which will
cause the unit to lock up in a RED
condition.
3) Check for noise on lines at the
power terminals and/or output
relay terminals. Dirty line voltage
can cause the microprocessors to
reset and/or the unit to lock up in
a RED condition.
Cure(s): 1) If line voltage is low, you must find
a way to boost the voltage level.
2) The manufacturer will provide you
with MOV components which you
can then place on the power lines
of any device that may be causing
noise on the line voltage (i.e.,
Solenoids, motors, etc.)
PROBLEM: Light curtain gets a code "C" on
the display or sometimes won't go
GREEN.
Cause(s): Examine the locations of all light
curtains around the troubled unit.
When one unit can see another unit
(i.e., Receiver Pylon of unit 1 can
see Emitter Pylon of unit 1 as well as
Emitter pylon of unit 2), synchronization
