4.1 Shutdown list
If irregularities occur in connection with the running of the compressor, UniSAB III can be inspected to
determine the cause of these irregularities. In case of shutdown UniSAB III stores the operating situa-
tion, including time and date. This information can then be inspected on the display which is particularly
useful when searching the cause of a compressor shutdown. UniSAB III can store 30 shutdown situa-
tions where the most recent one replaces the oldest. In case of power failure UniSAB III does not lose
any information, it can be displayed again once the supply voltage has been restored.
