5.2.4
Component Temperature Limits Exceeded
Temperatures of components increase with the application of power.
At power settings above the MCP, components may reach their
limitations.
CAUTION:
The controller needs sufficient energy from the 12 V
batteries to power its cooling fans. When the 12 V
battery charge becomes low, the cooling fan speed will
be reduced resulting in the controller temperature
increasing and the HV system may shut down when
maximum controller temperatures are reached.
WARNING:
The system overrides the requested rotary know value
shuts OFF power to the motor when limit temperatures
are exceeded.
5.2.5
Take-Off Abort Procedure
When it is required to abort a take-off the following procedure is
recommended:
To remove power immediately either:
•
Turn command knob fully ant-clockwise, or
•
Push the EXT/RETR toggle switch downwards
If the take-off must be aborted during ground roll, apply wheel
brake as required
If the take-off must be aborted when airborne, it is critical to
ensure a safe approach speed is maintained while the power is
cut. Immediately lower the nose of the aircraft from the
powered climb attitude to the unpowered glide attitude. Use the
airbrake and the wheel brake as required.
NOTE:
Switching off the RES master switch while the system
is drawing high amperage leads to a very abrupt
disconnection of the HV relays which could damage
the HV batteries.
