3.33. Heterogeneous power control
The Heterogenous power control function is like a program-
mable circuit breaker. It allows the user to set a maximum
power to be used by the device in its entirety. If the maxi-
mum is reached then specific parts of the load are switched
off (disconnected) according to a predefined priority.
GPC-M always has priority and is switched off last. If power
control is enabled for several modules, the disconnection
sequence starts with the module with the highest number
(GPC-E2 before GPC-E1 and GPC-M, GPC-E1 before
GPC-M).
