Protection - safety
- see figures 7.8.2 and 7.8.5
The electrical power system provides systems protection in case of :
-
overvoltage
-
short-circuits
In case of disconnection of starter generator or stand-by generator following a failure,
MAIN or ST-BY reset can be done by pressing corresponding GENERATOR RESET
MAIN or ST-BY push-button.
A battery reset is done by setting the SOURCE selector to OFF and back to BATT.
In case of disconnection of ground power unit following a failure, it is possible to
re-activate the system by turning the SOURCE selector to OFF and setting it again to
GPU position to reset the protection.
A crash lever located on upper panel center part allows isolating simultaneously
BATT BUS bar and setting to OFF the SOURCE and GENERATOR selectors when
lowered. In this case all bus bars are isolated from generators.
