LASAR Ignitions

Attention LASAR Users

Unison industries has sent out the attached advisory to LASAR users. The following is an excerpt of the advisory. If your aircraft is equipped with a conventional starter motor please disregard this notice.
Notice to Lasar Customers

The enclosed 12 volt LASAR system requires approximately seven (7) volts to the LASAR controller o ensure good ignition performance during normal engine starting. If input voltage to the controller falls below seven (7) volts, the LASAR system defaults to the backup magneto operation which may result in poor engine starting.

Input voltage to the LASAR controller is determined by the condition and location of the battery, the condition of the aircraft wiring system, and the amount of current drawn by the engine starter. A battery located in the tail of the aircraft or the use of a starter motor that draws a high level of current can reduce the input voltage to the LASAR controller. A partially charged battery or loose and corroded battery terminals can also reduce input voltage to the controller. If any of these conditions cause the input voltage to the controller to fall below seven (7) volts, the engine may fail to start, even though the engine is being turned over by the starter motor.
