Dental Light Circuit Breaker Locations
A circuit breaker will interrupt the flow of electricity under abnormal conditions. If the circuit breaker should trip, inspect the wiring to ensure there are no
shorts, and reset by pushing the circuit breaker. If the circuit breaker for the dental light is located on the power supply, its location varies by chair. For non-chair
based lights, the operatory circuit breaker is used.

Dental Light Shield Cleaning
Halogen Dental Light Shield
1. Turn off the dental light.
WARNING To avoid personal injury, be sure that the light has
cooled before cleaning it.
3. Release the toggles on either side of the light to remove the light shield.
4. To clean the light shield use a small amount of non-abrasive liquid soap and
warm water to wash it. Rinse and dry with a non-abrasive, lint free cloth.
If necessary, soak the pad or cloth with water or with a diluted solution of
mild dish washing liquid before cleaning. Make certain no residue remains on
the surface. Do not use abrasives or chlorine (such as household bleach) on the
surface of the reflector. These can damage or discolor the reflector surface.
CAUTION Do not rub heavily, clean the light shield when it is hot,
or soak the shield assembly in cleaning solution. Doing so may
damage the shield assembly components. Clean the light shield
only as instructed.
CAUTION Do not attempt to install the light shield if it has
a broken tab. Contact your authorized A-dec dealer for a
replacement shield and install before operating the light.
LED Dental Light Shield
A-dec recommends barriers to protect the dental light shield. In the event that
the light shield needs to be cleaned, carefully clean the light shield in place
using a soft cotton cloth with non-abrasive soap and water.
Do not remove the shield unless absolutely necessary. The shield is fitted with
a gasket to keep dust and debris from entering the lens assembly. If liquid or
dirt should bypass the gasket, the shield may be removed for cleaning.
CAUTION Only remove the shield if absolutely necessary. Use
a at-blade tool that won’t damage the light housing. After
removing the shield, do not touch or attempt to clean the multilens assembly or you may damage the components.

Dental Light Troubleshooting
This table contains tips and troubleshooting information to assist you in diagnosing dental light problems. This table is not intended to cover every situation, but
includes the most common problems that you may encounter.
LED (570L - 577L), 371, 372, 571, 572, 6300 Troubleshooting
ProblemPossible CauseDescription
Light does not work (light
connected to 311 chair circuit
board).
The bulb has failed (non-LED
dental lights).
The dental light circuit
breaker, CB6, has been
tripped or the power supply
has failed.
Check for voltage at the bulb socket, if voltage is present, replace the bulb.
Check the color of the bulb, replace if discolored.
• Check the circuit breaker and reset it. If the circuit breaker trips again, disconnect P4, J5, and J6 on the 311 chair board. If
the circuit breaker trips again, replace the power supply.
• If the circuit breaker does not trip, reconnect P4. If the circuit breaker now trips, replace the 311 chair circuit board.
• If the circuit breaker does not trip, reconnect the connections to J6 (if any). If the circuit breaker now trips, replace the
switch wiring to the 571-300 dental light.
• If the circuit breaker does not trip, reconnect the connections to J5. If the circuit breaker trips, replace the dental light.
371 or 372 Dental Lights on a 511 chair:
• If CB5 on the 300 W power supply is tripped, disconnect the dental light connector at the power supply and reset the
circuit breaker. If CB5 trips again, replace the power supply. Connect the dental light to the power supply, if CB5 trips,
replace the dental wiring harness or the adapter cable wiring.
371 or 372 Dental Lights NOT on a 511 or 311 chair:
• If the dental light circuit breaker on the 300 W power supply is tripped:
• Disconnect the dental light connector at the power supply and reset the circuit breaker.
• If the circuit breaker trips again, replace the power supply. (Connect the dental light to the power supply.) If the circuit
breaker trips, either the dental light wiring harness, switch wiring, dental light circuit board, or dental light circuit
board power cable has failed. Connect one at a time to determine the location of the failure.
571 Dental Lights:
• If CB5 on the 300 W power supply is tripped, disconnect the dental light and reset the circuit breaker. If CB5 trips gain,
replace the power supply. Connect the dental light to the power supply and if CB5 trips, the dental light wiring harness or a
switch is faulty.
572 Dental Lights:
• The dental light circuit breaker is near the power transformer. If the breaker is tripped, disconnect the dental light wiring
harness from the transformer and reset the breaker. If the breaker trips again, reset the circuit breaker. If the breaker
does not trip, the dental wiring harness or a switch is faulty.
The bulb socket is faulty
(non-LED dental lights).
Replace the socket.
ProblemPossible CauseDescription
Light works from the
touchpad(s) but not from the
dental light switches.
Light works from the dental
light switches.
Loose connection in the
dental light wiring harness.
Faulty data line from the
touchpad to the circuit board.
Verify that the wiring is connected properly.
Check the connections at the dental light switches and terminals H5 and H6 on the circuit board.
Temporarily substitute a known good data line from the touchpad to the circuit board, if the light works from the touchpad,
determine and replace any bad bypassed data lines.
Light head is loose or difcult
to position.
Flexarm drifts.Tension adjustment nut inside
Track light trolley drifts.Track is not level.Use wedges to level the track light ceiling pallet (p/n 017.017.00).
Track trolley light bounces
back when pushed to the end
of the track.
Light intensity is dim,
inconsistent, or the color is
distorted.
Unsatisfactory light pattern.Light is out of focus, reector
Rotation tension screws are
too loose or tight.
the exarm is too loose or
tight.
Power cable is hanging up
inside the track.
Reector or light shield may be
damaged (non-LED dental
light).
For the 372 Dental Light, the
intensity switch is in the
medium or composite
position.
The mains voltage is low.Verify the mains voltage is within specications: 100/110-120/220-240 VAC
Adjust the appropriate axis tension.
Adjust the exarm counterbalance.
Check power cable in track for proper routing. If you cannot correct the routing of the cable, replace the cable assembly.
Inspect the dental light shield and reector for damage or contamination. Replace or clean as necessary.
CAUTION: Abrasives, disinfectants or chlorine damage the shield and reector. Refer to the Instructions for Use for cleaning
instructions.
Check the intensity switch position.
NOTE: Turning the light on when the intensity switch is in the composite position results in medium intensity.
1. Focus the light.
or light shield may be
damaged (non-LED dental
lights).
2. Check the light shield for severe abrasions, and replace if necessary.
3. Clean the reector and light shield.
