AC Mode Wiring
When the PFC-7500 is used in the
AC Mode, the Potter Model WLT
Transformer must be connected to
the same branch circuit as the FACP.
An AC power fail can then be
delayed 6 to 12 hours by the
PFC-7500 programming. See
section 5.4 in the PFC-7500
Programming Manual
(Stk# 8910225).
The FACP must not indicate AC Fail
to the PFC-7500.
Form C alarm contacts
activate on General Alarm.
Form C trouble contacts
activate on General Trouble.
General Trouble must not be
used to indicate AC power fail
unless it can be delayed at
least 1 hour.
Form C or A contacts activate
on Supervisory condition.
Form C contacts activate on
AC power fail. Use on
PFC-7500 in DC Mode only.
Must delay AC power fail at
least 1 hour.
DC Mode Wiring
When the PFC-7500 is used in the DC
Mode, the operating range of the FACP
must be between 18 and 30 VDC.
The FACP must indicate AC power fail on
an independent relay output. This output
must delay the AC power fail at least 1
hour.
