The A1on < A1oF setting causes the alarm inverse action, i.e. the output is swit-
ched on if the prescribed value decreases below the A1on value and the output is
switched off if the value, increases above the A1oF threshold.
Analog outputs for parameters accepting values:
-
positive and negative
(table 5), are bi-directional, i.e., for negative parameter
values, the analog output signal is also negative,
-
positive
, they are unidirectional, i.e., for positive parameter values, the analog
output signal is positive (from the range: 0...+ 5 mA).
4.2.5. Page configuration mode - P
This mode is used to select quantities displayed simultaneously on the meter, i.e.
to define user’s pages.
A list of possible quantities and their codes are inserted in the table 5.
