INSTALLATION OF LASAR
®
SYSTEM WITH COCKPIT ENUNCIATOR LIGHT
Some installations of LASAR
®
systems may include an optional cockpit enunciator light which becomes
illuminated when the LASAR
®
system is operating in the backup mode. Illumination of this light with the
ignition switch in the “BOTH” position and the engine running indicates that the LASAR
®
system has
automatically switched to backup operation and that the aircraft may require service prior to the next
flight. The pilot should land the aircraft where such service is available. Because LASAR
®
provides
multi-level mechanical backup ignition, no changes in piloting procedures are necessary if the cockpit
light becomes illuminated during flight.
When operating in the backup mode, the orange wire of the Low Voltage Control Harness provides a
return ground path for the enunciator light through the controller. If the light is receiving adequate input
power and is connected to the orange wire, the light will become illuminated when the LASAR
®
system
is operating in the backup mode. Proper operation of the light should be confirmed during each pre-
flight magneto check (refer to Section 3).
The following hardware is compatible with the LASAR
®
system. Equivalent alternatives may be
substituted.
