2.7 Fault Detection or Lamp Bypass Functions
This product complies with the requirements of FAA EB67 and GB/T 7256, and integrates
single lamp fault detection function; Or, it can provide the option of lamp bypass function in
accordance with the requirements of FAAAC150-5345/46.
Single lamp fault detection function: The light will take automatic action to cut off the input
when any malfunction occurs on the lamp and achieve an effect similar as the open circuit of
ordinary halogen light once it is burnt. This function is generally used in conjunction with single
lamp controller, to help single lamp control and monitoring system to identify any failed light. And
it is integrated into the interior of the lighting fixtures, without need of any external device. Please
specify this function during the ordering if needed.

In case of no special requirements, 65W isolation transformer lighting is recommended.
※Any isolation transformer whose power is greater than 100W shall not be used for the
fixture that has the single lamp fault detection function.
Lamp bypass function: After any failure occurs to the lamp, relatively, the input terminal of
light will be short to the isolation transformer. This function is generally applicable to occasions
that one isolation transformer carries multiple lighting fixtures. If one or more of these lighting
fixtures is or are damaged, the remaining lighting fixtures will not go out thereby. This function is
integrated into the interior of the lighting fixtures, without need of any external device. Please
specify this function during the ordering if needed.

3.2 Identification of Different Types of Lighting Fixtures
○The model of each lighting fixture is attached to its bottom.
○The colorful dot identification mark is attached to the light outlet of each lighting fixture,
respectively meaning the luminous color and direction of the window where the colorful dot is
located.
○According to the specific provisions of FAA, ICAO and CAAC, correctly select the lighting
fixtures and ensure their window directions.
Before installing the lighting fixture, confirm the window color and luminous direction.
※Avoid rework or other problems.
This sign means the light color
and internal toe-in direction.
Left red dot: means red light and
left toe-in
Middle white dot: means white
light and no toe-in
Right green dot: means green
light and right toe-in

3.3 Installation Tools
Choosing right tools not only can ensure the correct and reliable installation of the lighting
fixtures, but also can reduce unnecessary safety accidents. Special Tools listed in the table may be
purchased from the manufacturer or any distributor. Universal tools are available on local hardware
market. Please pay attention to measurement range during procurement.
○General tool: Torque wrench: be used to tighten the screw,
which may be used with various sleeve wrenches and directly
purchased from various hardware stores, manufacturer or
agent.
Recommended range is 10-40N·m.
○Universal tool- Torque screwdriver: be used to dismount
screw, equipped with PH2 cross screwdriver, and sellable in
various hardware stores.
Recommended range is 1-6N.m
3.4 Screw and Torsion
The torque listed in this section is only for reference by maintenance personnel. Correct
fastening force of screw can ensure normal operation of the lighting fixtures. If screw is too tight, it
will easily damage the lighting fixtures; on the contrary, if screw is easy to fly out, it may cause an
accident.
