Note:
The relative alarm are “relative” to the current Set
Point (this may be different to the Target Set Point if
you are using the ramp to Set Point function).
[42] Ab3 - Alarm 3 function
Available:
When [41] AL3t is different from
nonE
.
Range:
0... 15 with the following rule:
+1
Not active at Power ON;
+2
Latched alarm (manual reset);
+4
Acknowledgeable alarm;
+8
Relative alarm not active at Set Point change.
Example:
Setting Ad3 equal to 5 (1+4) the alarm 3 will be
“Not active at Power ON” and “Acknowledgeable”.
Note:
For other details see [26] Ab1 parameter.
