External BFP (Bussed Field Power Supply) Monitoring

The status of up to four Bussed Field Power supplies can be monitored through the status
bits of the PNS. For details, see 4.1.2.3, "PNS Power Status Register (PPSR)." The Bussed
Field Power monitoring connector is shown in the picture below. There are two terminal
marked as 24VA and 24VB provided for connecting the 24V terminal (+) of the power supply.
There are four terminals marked as BFP0V are provided to connect the 0V terminal (-). The
power status signals from the power supplies are required to be connected to terminals
marked as PF3, PF4, PF5 and PF6. Please note that this functionality shall only work if the
power status signal is "open-collector" type: low impedance to BFP0V when power is OK and
high impedance if power fails.
The terminal marked as "TERM1" & "TERM2" are reserved for future use.
1.4.4 12V DC HVCC/PNS Power supply monitoring
The status of up to two redundant 12V Power supplies (HVCC and/or PNS power) can be
monitored through the status bits of the PNS. For details, see 4.1.2.3, "PNS Power Status
Register (PPSR)." The HVCC connector is shown in the picture below. The power status
signals from the power supplies are required to be connected to terminals marked as PF1
and PF2. Please note that this functionality shall only work if the power status signal is "open-
collector" type: low impedance to GND when power is OK and high impedance if power fails
