Symptom
Possible cause
Remedy
Operation LED does not
light
1. Disruption of power or inadequate power
2. Bad wiring connection or broken wire, short
1. Correct power source
2. Check and correct wiring
1. Disruption of power or inadequate power
2. Bad wiring connection or broken wire, short
3. Reflection of beam is flooding receiver and sent into
the receiver
4. Beam interruption time is shorter than response
time
1. Correct power source
2. Check and correct wiring
3. Remove reflecting object. Set beam power to Low.
Contact Pulnix for further remedies
4. Adjust response time
Receiver Alarm LED
does not light when the
beam is broken
Receiver Alarm LED
stays lit
1. Alignment is off
2. Shading object between transmitter and receiver
3. Optics of units are soiled
4. Frequency channel setting on transmitter does not
match with that on receiver
1. Check and adjust
2. Check site / remove any possible obstacles
3. Clean the optics with a soft cloth
4. Readjust to be the same channel
1. Bad wiring connection
2. Change of supply voltage
3. Shading object between transmitter and receiver
4. The wiring of power machine is located nearby
transmitter and receiver
5. Unstable installation of transmitter and receiver
6. Optics of units are soiled
7. Improper alignment
8. Small animals may pass through the 4 beams
9. Beam power switch is set at L, which does not keep
enough sensitivity allowance
1. Check again
2. Stabilize supply voltage
3. Remove the shading object
4. Change the place for installation
5. Stabilize
6. Clean the optics with soft cloth
7. Check and re-adjust
8. Change environments or the place for installation
9. Set beam power switch at H and make the unit
gain-locked with receiver cover detached
