1.6.1.14 Line Voltage Monitoring

An indication of the level of line voltage is provided at the PIC µController port A bit 0 (Pin 2). For a

48 volt line the level at this point is

≈ 3.0V d.c. This pin of the µController can be re-configured as an

ADC input and, with appropriate firmware, be used to monitor the line voltage. Note that this feature

is not used by the current firmware revision.
