Operating Procedures
Connect DC Power To Aircraft (Low Power Demand)
Low power demand is defined by a requirement of 10 amps or less. Connect dc power to aircraft ground
power receptacle. DC bus power should come on and aircraft voltmeter should indicate 28.5 Vdc to 27 Vdc
(26.5 Vdc minimum). If aircraft power demand is less than 5 amps converter output will remain at 28.5
Vdc (only one GREEN LED status indicator bar will illuminate). If aircraft power demand exceeds 10 amps
converter voltage output will decrease and two or more LED status indicator bars will illuminate.
Connect DC Power To Aircraft (High Power Demand)
High power demand is defined by a requirement of greater than 10 amps. Connect to aircraft ground power
receptacle. DC bus power should come on and aircraft voltmeter should indicate 28.5 Vdc to 23.5 Vdc (23
VCD minimum). If current demand is greater than 10 amps, converter output voltage will drop below 28.0
Vdc and LED status indicator lights will illuminate indicating current is being drawn from the power cells.
The greater the current draw, the quicker the LED status indicator will approach red. Note the LED status
indicator shows the status of the power cells.
Engine Starting
UNPLUG AC POWER CORD BEFORE STARTING ENGINE WITH TI206 MPU-24
Prior to engine start, ensure power cell charge is sufficient to provide an efficient engine start. Users should
follow ground power engine starting procedures as specified in the aircraft’s operator manual.
!
When all LED status indicator bars illuminate, both the converter and power
cells are supplying 24 Vdc power output for current demands above 10 amps.
