PARAMETER

1st GROUP

The controller parameters have
been organized in group, accord-
ing to their functionality area.
# A Is. p
AL1 alarm
threshold
The threshold is presented only if
the controller have been configured
with 2 alarms. ( Digit L of the con-
figuration code assigned to 4 or 5)
# A 2s. p
AL2 alarm
threshold
The alarm occurrences handle the
OP1 and OP2 outputs, in different
ways, according to the configured
types of alarms, as illustrated.
# p . b .
Proportional
band
This parameter specifies the pro-
portional band coefficient that mul-
tiplies the error (SP - PV)
