- If the calibration deteriorates:
The protection substitutes the deteriorated calibration for the default calibration
and the DEFAULT CALIBRATION BY signal is activated.
The calibration loss implies the need to recalibrate the relay in the factory. Since it
is not always possible to immediately disconnect the relay and send it back to the factory
so that it can be recalibrated, using the default calibration settings is acceptable as long
as the default calibration setting is maintained below 5% error. However, it is not
advisable to postpone the recalibration longer than absolutely necessary.
Cold/warm boot
Any system reset causes a cold boot. During this boot the self checks are
performed. If no critical errors are detected a warm boot is performed.
During a warm boot the system variables and parameters are initiated and the
corresponding LED on the front panel of the relay is lighted.
Cold boots as well as warm boots are saved as events.
