Ground Test Before Each Flight - FES GEN2 14S User Manual

FES BATTERY PACK GEN2 Version 1.18

4.2 Ground test before each flight

It is strongly recommended to perform short ground test run before each
flight, to be sure that everything works fine.
1. Remove a tail dolly in order to achieve safe propeller clearance.
2. Open battery compartment cover.
3. Check that "Power switch" is OFF.
4. Insert "connecting cable" between the front pack + terminal, and rear pack –
terminal.
5. Seat into the cockpit of the glider, and close canopy.
6. Check that nobody is in line of propeller disk or in front of sailplane.
7. Switch ON FCU, and wait a few seconds until appearance of normal screen.
8. Switch ON "Power switch".
9. Wait about 5 second, and battery capacity bottles should get back to 100%
value (this will happen only if total voltage is above 114V).
10. Gently rotate throttle knob clockwise in order to start motor. Use only small RPM, just
to check if system works normally.
New battery capacity will be stored to the FCU memory, only if
motor is started, for short time.
In case that you would like to test system at max power, somebody needs to
hold a fuselage tube down, and hold a glider.
11. Check if propeller braking and automatic positioning is working properly.
Standard type of "Connecting cable", as used on most FES systems.
