When the ALARM LED is on, the download is inhibited.
The configuration download starts as soon as the relevant push button on the
Operating Tool is clicked.
The previous configuration inside REF 542plus is destroyed and overwritten by the
new one.
REF 542plus is fully operational during the download. After the download,
REF 542plus starts to write the new configuration in the non-volatile with a low
priority task in background. This task might take several seconds.
Do not switch off Base Unit power supply during the storing. The
whole unit configuration might be corrupted and a new configuration
download might be necessary.
The download is possible in all control modes, provided the status of the protection
is switched by the corresponding electronic key in operational mode.
Communication to the SCADA system is operational during the download.
After the download, REF 542plus automatically starts with the new configuration.
