starting procedure as specified in aircraft operators manual.
5. REMOVING DC POWER SUPPLY FROM AIRCRAFT
a. Remove DC power cable GPU connector from aircraft.
b. Remove DC power cable connector from Turbo Start
(if necessary).
4-3
4-7. 24 VDC GROUND POWER (WITH 120/240 VAC POWER) SYSTEM HIGH POWER DE-
MAND (21 amps and above) OR ENGINE STARTING.
1.
TRANSPORT UNIT - The Turbo Start 2000 is easily transported us-
ing the wheels that are incorparated into the unit. The AXEL
EXTENTION kit (included with the unit) ensures that the Turbo Start
2000 is stable. The unit is engineered to be pushed rather than
pulled.
2.
CONNECT AC POWER CORD TO UNIT (
CHECK FUSE WINDOW FOR PROPER SET-
TING
).- - Ensure 120 or 240 VAC power cord is properly connected to
an approved AC power supply.
Unit shall be in horizontal position to
ensure unit’s vent ports are free from blockage
. After approximately
5-8 seconds, unit’s LED status indicator will illuminate indicating
power cell state of charge. Cooling fan will operate. Ensure LED
status indicator and cooling fan are operational prior to continuing
to step 3.
3. CONNECT DC POWER CABLE TO UNIT - Ensure power cable connector is
fully seated into unit’s receptacle.
4. CONNECT DC POWER CABLE TO AIRCRAFT - Connect to aircraft ground
power receptacle. DC bus power should come on and aircraft volt
meter should indicate 27.5 VDC to 23.5 VDC (23 VDC minimum). If cur-
rent demand is above 20 amps, converter output voltage will drop be-
low 28.5 VDC and two or more LED status indicator bars will illumi-
nate. At approximately 21 amps of current demand, converter output
voltage will be regulated at 24 VDC output and the last (RED) LED
status indicator bar will illuminate.
NOTE
When all LED status indicator bars illuminate, both the converter and
power cells are supplying 24 VDC power output for current demands
above 21 amps (see paragraph 3-4).
5. ENGINE STARTING - UNPLUG AC POWER CORD BEFORE STARTING
ENGINE WITH TURBO START. (see paragraph 4-6.). Prior to engine
start, ensure power cell charge is sufficient to provide an efficient
engine start (see paragraph 3-7).
6. REMOVING DC POWER SUPPLY FROM AIRCRAFT
