Activate boot loader Activates the boot loader by writing the value
from ASIC2_serialLW.
Remote tripping through output bit R-TRIP causes a trip if a phase current of at least 85
% of the minimum mark of the variable overload release on the PKE control unit flows
through all three main circuits (for example PKE-XTUA-4 → Imin = 0.85 × 1 A =
0.85 A).
ATTENTION
The command "Remote trip PKE basic unit" is supported from the
following versions of the PKE trip blocks:
PKE-XTUA-1.2/4/12/32 PKE-XTUWA-32
PKE-XTUA-65
