Watt Demand Alarm
Units: Sets the units for watts demand measurement.
(kW or MW).
Threshold: Sets the watts demand threshold level in units
specified, at or above which the power demand
pickup occurs. After pickup, if the watt demand
falls below the specified threshold, a power
demand dropout event occurs. The demand
interval is set in the Demand Setting section
described later in this section.
Delay (m): Sets the number of minutes that the watt
demand must remain at or above threshold,
before the specified trip output occurs.
VAR Demand Alarm
Units: Sets the units for VARS demand measurement
(kVAR or MVAR).
Threshold: Sets the VARS demand threshold level in units
specified, at or above which the power demand
pickup event occurs. After pickup, if the VARS
demand falls below the specified threshold, a
power demand dropout event occurs. The
demand interval is set in the Demand Setting
section described later in this section.
Delay (m): Sets the number of minutes that the var demand
must remain at or above threshold, before the
specified trip output occurs.
VA Demand Alarm
Units: Sets the units for VA demand measurement.
(kVA or MVA).
Threshold: Sets the VA demand threshold level in units
specified, at or above which the power demand
pickup event occurs. After pickup, if the VA
demand falls below the specified threshold, a
power demand dropout event occurs. The
demand interval is set in the Demand Setting
section described later in this section.
Delay (m): Sets the number of minutes that the VA demand
must remain at or above threshold, before the
specified trip output occurs.
Current Demand Alarm
Pickup: Sets the current demand pickup level, at or above
which the current pickup event occurs. After
pickup, if the current demand falls below the
specified pickup, a current demand dropout
event occurs. The demand interval is set in the
Demand Setting section described later
in this section.
Delay (m): Sets the number of minutes that the current
demand must remain at or above threshold,
before the specified trip output occurs.
NOTE: Check the Demand Logging interval. The delay for alarm
starts after the demand is logged, and the demand
remains at or above threshold for the time specified in the
setting delay for alarm. For example if the demand interval
is set to 15 minutes and the delay for the demand alarm is
set to 15 minutes, the system alarm pickup event occurs
after 30 minutes.

I THD Alarm
Threshold: Sets the current THD magnitude threshold
level, at or above which the current THD
pickup event occurs. After pickup, if the
current THD magnitude falls below the
specified threshold, a current THD dropout
event occurs.
Delay(s): Sets the number of seconds that the current
THD magnitude must remain at or above
threshold, before the specified trip
output occurs.
V THD Alarm
Threshold: Sets the voltage THD magnitude threshold
level, at or above which the voltage THD
pickup event occurs. After pickup, if the
voltage THD magnitude falls below the specified
threshold, a voltage THD dropout event occurs.
Delay(s): Sets the number of seconds that the voltage
THD magnitude must remain at or above
threshold, before the specified trip output occurs.
Breaker Alarm
# of Operations: The FP-5000 counts the number of breaker
operations. A breaker operation is counted
when the breaker is opened after being closed
for 3 cycles based on the state of the 52a and/
or 52b contact inputs. This setting is used to
provide a breaker alarm indication if the breaker
is operated more than the specified settings.
This counter is intended to be used for
scheduling breaker maintenance after a
number of operations.
Isum INTR Amp: In addition to counting the breaker operations,
the FP-5000 records the interrupted current
per phase and accumulates the total current
interrupted on a per phase basis. If any of the
accumulated interrupted phase currents exceeds
this setpoint then an alarm and indication will
occur. This accumulator is intended to be used
for scheduling breaker maintenance after the
accumulated interrupted current exceeds
the setpoint.

5.5.4 Logging Settings

The following are setpoints needed to configure
the Logging functions.
Current Demand
Interval (m): Sets the interval in number of minutes from 1 to
60 minutes in 1 minute intervals. After each
specified interval, the average current for that
period is calculated and updated.
