For the maintenance purpose, it is possible to generate “faults” related
information for a particular date and time. It also possible to see the Status
of the Capacitor Banks of TPF-56 Unit, at a specified date and time.
Please refer page no. 20 of this user manual for the connection
diagram between PC and the TPF-56 Unit.

monitoring (EWPF):
The TPF-56 has the ability to detect the “power-failing” condition by way of an
internal “Early-Warning” of impending AC Input Aux. Power Failure, and takes
preventive measures for the following:
In case of “power-failing” Early-Warning condition, the TPF-56 saves all the
dynamic parameters in its non-volatile memory (EEPROM) along with RTCC
current date and time. So, the “Power-Down” event is precisely known.
Similar Record is created at the time of AC Aux. Input Power-Up. This enables
the PC Side Data-View / Data View Software to find the interval for which the
TPF-56 did not receive Power Supply.
After “saving” in to non-volatile memory operation, the LCD back-light
which was off at the detection of “Power-Failing”, it flashes on once which
indicates that the memory saving operation has been successfully carried-out
by the TPF-56 Unit.
“Early warning Power Failed” additionally has one critical functionality for
taking care of critical value storage in EEPROM. This prevents any data loss in
Interval or Events records or Energy Counters or Capacitor kVAr values to be
lost in case of Battery Fault or Replacement of Battery even with Power Down
condition.
