Indication of output states:
OUT 1 (Alarm 1); OUT 2 (Alarm 2);
OUT 3 (Alarm 3)
"Raise" and "Lower" keys:
These keys are used for any operation that
requires a numerical parameter to be raised or
lowered. •• The speed of change is proportional
to the time the key is pressed. •• The operation is
not cyclic: once the maximum (minimum) limit is
reached, there will be no further increase
(decrease) of the value, even if the key remains
pressed.
The keys can be configured to perform reset,
hold, display of the peak value, etc. as
determined by the 't.U.' and 't.d.' parameters on
the 'In' menu.
PV display: Indication of process variable ••
Indication of 'HI' or 'Lo' out of range •• Indication
of open circuit (br) or short circuit (Er)
•• Display of configuration and calibration
messages
