0 Direct Absolute Normal
1 Inverse Absolute Normal
2 Direct Relative Normal
3 Inverse Relative Normal
4 Direct Absolute Symmetrical
5 Inverse Absolute Symmetrical
6 Direct Relative Symmetrical
7 Inverse Relative Symmetrical
Alarm 1 is only absolute
The deviation alarm refers to the previous absolute.
by adding the following numbers to the value shown in the table, you can ena-
ble a series of supplemental functions:
+8: disable power-on until first trip point.
+16: enable memory latch.
+32: change color of PV display in case of active alarm
+64: deviation alarm refers to input IN3 (except code Ar.n = 2)
+128: deviation alarm refers to input IN3 (except code Ar.n = 3)
+256: change color of PV display if limit is exceeded
(only for alarms with timed delay)
+512: enable string if alarm is active
+1024: enable string if limit is exceeded (only for alarms with timed delay)

N.B.:
For deviation alarms, reference quantities must have the
same decimal resolution
