 Conventionally, the controller can be set to operate without alarm in the range
from 80% to 120% of the nominal battery voltage. With a different DC voltage
than specified, the controller raises an alarm.
 Undervoltage and overvoltage thresholds are defined by hardware. After start-up,
controller is fully operative if the supply voltage stays within these limits.
 Undervoltage is evaluated on the KEY input (A3); overvoltage is evaluated on the
positive battery terminal +B.
