After PLN power failures, radar system became unstable (not only last
night). Errors of AZ/EL servo drives and GDRX-SP appeared many times.
Because of this, the team MPR decided to deactivate auto mode and to
operate the radar using only generator power again. (Still in auto mode,
but unplugged the PLN cable.
