LOAD LOCKED
ON MAINS
Load is locked on mains because 3 transfers on mains have
been detected in a short time (default 30 seconds).
Transfer will be free again after a time defined by respective
been detected in a short time (default 30 seconds).
Transfer will be free again after a time defined by respective
parameter (default 30 seconds).

LOAD ON MAINS
BY ERROR DETECTOR
Load is transferred to mains because the error detector
detected a disturbance on the output voltage.
