by external sensors (see chapter 5.11). The recommended temperatures for fault free operation of
HYDROCAL1005. Temperature for sensors and oil below 30°C and over 60°C are generally not to
expected and indicate a problem in the heating circuit. If temperatures are outside this range, then
external (air) temperature and oil temperature must be considered. Lower sensor temperatures are
possible during severe frosts or when transformers are switched off. Under certain circumstances
temperatures higher than 60°C can exist with very hot oil in the transformer without being a problem
of the heating circuit. In such a case, the measuring result can have additional error deviations.
A total 16 alarms can be defined on the HYDROCAL1005 unit. If several alarms use the same output
line, the status of alarms will be connected by an „OR“- statement, resulting to activate the corre-
sponding output if an alarm is triggered.
In the overview of alarms, (Alert Setup Overview) the following displays forms can be selected:
Either List / View in form of a list
Or Details view (listing details of alarm settings)
Or Symbol view (presenting alarm settings as symbols)
