Operating Procedures
Engine Starting
Prior to engine start, ensure power cell charge is sufficient to provide an efficient engine start. Check dc
power cable for secure and correct installation prior to engine starting. Follow ground power engine starting
procedure as specified in the aircraft or vehicle’s operator manual.
Removing DC Power Supply From Vehicle
Remove dc power cable GPU connector from vehicle.
1.
Remove dc power cable connector from TI3000 GPU-24-INV-1800 (if necessary).
2.
Reinstall dc receptacle’s protective cover.
3.
High Power Demand
High power demand is defined by a requirement of greater than 50 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
Vdc minimum). If current demand is greater than 50 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.
NOTE
!
When all LED status indicator bars illuminate, both the converter and power
cells are supplying 24 Vdc power output for current demands above 50 amps.
CAUTION
!
Unplug ac power cord before starting engine with TI3000 GPU-24-INV-1800
For long term power requirements the TI3000 GPU-24-INV-1800 can be slaved to a vehicle charging system.
To avoid damage to the vehicle or the inverter unit, several precautions must be taken.
The vehicle must have a sufficient charging system: 24Vdc @ 100 A. The alternator of the slaved vehicle must
be operating in it’s excited state. The slave vehicle engine must be operating at 1800RPM.
WARNING
Never connect or disconnect the inverter to a vehicle while the inverter is
running. Always turn off the ac circuit breaker, inverter power switch, and dc
circuit breaker before connecting or disconnecting to a vehicle or aircraft.
To slave to a vehicle the NATO to dc cable must be attached to the inverter
1.
The NATO connector must be attached to the vehicle
2.
The ac load must be connected to the inverter GFI outlet and the GFI reset if it has tripped
3.
The slave vehicle engine must be brought up to 1800 RPM
4.
The dc circuit breaker of the inverter must be set to on
5.
The inverter power switch must be set to on
6.
The ac circuit breaker must be set to on
7.
CAUTION
!
Please ensure that the Inverter is turned off prior to performing an engine start.
