CAUTION!
Alarm in the event of probe break or short-circuit Even the
definitive faulty values probe break (display "oooo“) or
short-circuit (display "uuuu“) only lead to a set alarm bit
and, thus, to a multi-input alarm with the LED flashing red
when at least one alarm (regardless of LoAL or HiAL) was
configured! If you only want to receive probe break / short-
circuit alarms without any other limit value monitoring,
activate an alarm using a limit value outside of the range of
occurring actual values. Example: Your actual value can be
between (-10 to +200) °C. Pure probe break / short-circuit
alarms can be achieved, e. g. by a HiAL configuration with a
limit value of 300°C or a LoAL configuration with a limit
value of -100°C.
Fly back down/up (xx.Min) and up (xx.Max)
The minimum and maximum values for each channel are saved and shown on the
display when requested. In this context, overrange and underrange are not taken
into account. These values can be reset using the keyboard or via interface.
Having reset the fly back, the current value is taken over and the fly back
function restarts.
