Attributes
ALARM
ALARM NUMBER
ALARM
R W
The parameter shows and sets the alarm to be configured, identified by its number.
Unit of measurement:
Number
Options
:
1...ALRM.N
= Identifying number of alarm, where ALRM.N is the total number of alarms, setting
by submenu MODE.

d.i.x
DIRECT/INVERSE DEFINITION
ALARM
R W
The parameter shows and sets the behavior of alarm number “x” with respect to the alarm limit and hysteresis.
Direct or inverse defines when the alarm has to trip. For a detailed explanation of this behavior, see paragraph “5.6.1.
Generic alarms AL1...AL4” on page “5.3.1. Generic alarms AL2-4” on page 74.
The parameter only appears for ALARM=2, ALARM=3 and ALARM=4.
Only DIREC for Alarm 1
Unit of measurement
: -
Options
:
DIREC
=
Direct alarm
INVRS
= Inverse Alarm

ABSOLUTE/DEVIATION DEFINITION
ALARM
R W
The parameter shows and defines the reference value of alarm number “x” for the alarm limit.
For a detailed explanation of the difference between absolute and deviation, see paragraph “5.6.1. Generic alarms AL1...
AL4” on page “5.3.1. Generic alarms AL2-4” on page 74.
The parameter only appears for ALARM=2, ALARM=3 and ALARM=4.
Only ABSLT for Alarm 1
Unit of measurement
: -
Options
:
ABSLT
=
Absolute alarm
RELAT
= Deviation alarm
4.6.4. n.S.x - Selecting hysteresis type

Attributes
n.S.x
NORMAL/SYMMETRIC DEFINITION
ALARM
R W
The parameter shows and sets the method for applying hysteresis for alarm number “x” with respect to the alarm limit
value.
With normal, hysteresis is added to / subtracted from the alarm limit(s) based on the general alarm configuration. With
symmetrical, hysteresis is added to / subtracted from the alarm limit itself. For a detailed explanation of the difference
between normal and symmetrical, see paragraph “5.6.1. Generic alarms AL1...AL4” on page “5.3.1. Generic alarms AL2-
4” on page 74.
The parameter only appears for ALARM=2, ALARM=3 and ALARM=4.
Only NORML for Alarm 1
Unit of measurement:
-
Options:
NORML
= Normal alarm
SYMMT
= Symmetrical alarm (window)
