Performance Low warning
If the current of string (x) is LOW, a warning appears. The
conditions for this warning are:
1. The current of string (x) is out of deviation. D (deviation)
is the percentage to enter;
2. The current of string (x) is lower than the maximum
current of all strings minus the Offset;
3. Conditions 1 and 2 are present for at least a period as
long as the alarm delay.
Refer to figure 42.
