“0” and hysteresis value
greater than “0” (Par. 28
a .1 . H y . > 0).
NB: a) The example refers to alarm 1; function can also be
enabled for alarm 2 on model that include it.
b) With hysteresis value less than “0” (
a .1 . H y . < 0) the
dotted line moves under alarm setpoint.
 Table of Anomaly Signals
If installation malfunctions, controller will switch o regula-
tion output and will report the anomaly. For example, control-
ler will report failure of a connected thermocouple visualizing
e -05  ashing on display for other signals, see table below.
