10. TROUBLE SHOOTING CHECK SHEET for AX-250PLUS/500PLUS/350TF/650TF
1. “No Action” on the TRANSMITTER or RECEIVER after power has been applied.
Check to see that
power cables are
properly connected and
polarity is correct.
Check to see that input power is
within the product's requirements.
AX-250PLUS/500PLUS:10.5-30VDC
AX-350TF/650TF:10.5-30VDC
Correct terminal
connection and/or polarity.
Does the power supply output more
than 12VDC?
Call Technical Support.
Disconnect power cable from the power supply and the
Photoelectric beam and test for short or open circuit. Also test for
short circuit to ground.
Repair as required.
Power cables may be too long for the gauge being used. This will
cause the voltage to drop. Use heavier cable or use additional
power supplies closer to the farthest units. If you are unsure of the
proper wire gauge, call Technical Support.
The power line is short circuited or grounded.
Repair as required.
The power supply may be malfunctioning, repair is required, or
call power supply manufacturer.
NG
OK
OK
There is a possibility that
the power line has been cut.
Remove the power wires
from Power supply's output
terminals.
Measure the voltage. Does
the power now satisfy the
requirement?
YES
NO
YES
NO
NG
2. “No Action” on alarm zone even though the beams are completely blocked.
Alarm Indicator LED
lights but control
panel does not
recognize the alarm
signal.
Remove the alarm circuit
wires from the RECEIVER.
Check the action of the alarm
output relay. Does the relay
open when the LED Indicator
activates?
Check other items.
If the beam is interrupted
at a location far from the
RECEIVER, no alarm signal
is generated, but when the
beam is interrupted at a
location near the RECEIVER,
an alarm signal generated.
Call Technical Support.
The control panel may be
malfunctioning, call the control
panel manufacturer.
Re-program the Zone's “Loop
Response Time" appropriately.
If AX-350TF/AX-650TF beams are
used at the installation site, select
different “Frequency Channels"
for the beams causing the
interference.
NO
OK
Remove the alarm circuit wire
from the RECEIVER, and
check for short circuits on the
wires.
Are there any other outdoor
beams near the installation
site?
NO
NG
When the
RECEIVER'S cover
is removed and the
beams are blocked,
the Alarm Indicator
LED does not light.
The RECEIVER may be
affected by other beam
TRANSMITTERS, or the
beams are being re
fl
ected off
of a shiny surface.
When the mirrors of the
RECEIVER are completely
covered, an alarm signal is
generated.
The beam interruption time is
set too long.
The intended target does not
block both upper and lower
beams completely.
Re-wiring of the alarm circuit
wire is required. Replace or
repair as necessary
OK
Is the control panel zone's
“Loop Response Time" set to
within 1 second?
Remove power from all other
TRANSMITTERS and conduct
walk test.
YES
Does the Photoelectric Beam
work properly?
Check other items.
NO
Are there any surface
between the TRANSMITTER
and RECEIVER that are
re
fl
ecting the beam?
Turn the interruption time adjustment dial counter-clockwise one
graduation.
Does the RECEIVER work when both upper and lower beams are
completely blocked? If so, the installation height is not proper.
Adjust the installation height.
Remove the alarm circuit wire from the RECEIVER, place your volt
meter on resistance and measure the alarm output relay. Does the
relay open when power is removed?
Call Technical Support.
The unit may be affected by electrical noise. May need to use
shielded wire and/or metalic conduit pipe. Call Technical Support
if you are unsure of the proper shielding techniques.
Adjust vertical and/or horizontal alignment in order to move the
IR energy off the re
fl
ective surface. Monitor the beam strength
(Monitor Jack) while adjusting beam to insure stable alignment.
YES
Check other items.
“Change the lay-out of the beams
or call Technical Support for
further advice."
