M‑6280A Instruction Book
SECONDARY METERING STATUS
Voltage
Displays the real-time measured value of voltage
and includes any corrections made using the
user-selected VT correction voltage.
Delta Voltage
Displays the real-time calculated delta voltage.
Power Factor
Displays the real-time calculated value of power
factor with VAr Control Mode option.
Frequency
Displays the real-time measured frequency value.
PRIMARY METERING
Voltage
Displays the calculated primary voltage based on
the user-selected voltage multiplier, VT corrections,
and measured secondary voltage.
Neutral Current
Displays the calculated value of neutral current
based on the user-selected current multiplier, VT
correction, and measured secondary voltage.
Delta Current
Displays the calculated delta current for each Close/
Open operation.
Phase Current
Displays the calculated primary current based on
the user-selected current multiplier, and measured
secondary current with VAr Control Mode option.
Watts
Displays the calculated primary quantity based on
the user-selected voltage and current multipliers;
VT configuration (line‑to‑ground), single‑phase, and
measured secondary voltage and current with VAr
Control Mode option.
VArs
Displays the calculated primary quantity based on
the user-selected voltage and current multipliers,
VT configuration (line‑to‑ground), single‑phase, and
measured secondary voltage and current with VAr
Control Mode option.
VA
Displays the calculated primary quantity based on
the user-selected voltage and current multipliers,
VT configuration (line‑to‑ground), single‑phase, and
measured secondary voltage and current with VAr
Control Mode option.
CBEMA EVENTS AND COUNTER STATUS
The CBEMA Events and Counter Status element
of the Metering and Status screen provide the user
with current CBEMA events and a counter for each
event. See Section 4.1, Unit Setup for detailed
information regarding CBEMA monitoring setup.
COUNTERS
Operation Counter
A software counter which increments by one count
based on the Operations Counter configuration
either "Open or Closed" or "Close Only". The
counter can be set from zero to 999,999. Setting
the counter to zero resets the counter.
The counter accommodates 999,999 operation
counts and the number of counts stored in memory
is not affected by a loss of supply power. Total
operation count is displayed in the HMI Monitor/
Cap Information menu. This counter can be preset
to any value up to 999,999 in the Configuration/Cap
Settings menu.
Resettable Operations Counter
A software counter which increments by one count
based on the Operations Counter configuration
either "Open or Closed" or "Close Only". The user
resets this counter to zero by pressing ENT while
viewing the resettable operation counter screen
within the Monitor/Cap Information. No password is
required to reset the resettable operations counter.
Daily Operation Counter
The Daily Operation Counter is a software counter
that counts the number of Operation Counter
operations in the selected mode (Auto, Remote,
and/or Manual) over a 24 hour period that starts at
12:00 am. The Daily Operation Counter limit when
exceeded will block further operations until 12:00
am. This value is stored in non-volatile memory. A
single Open is allowed by Remote or Manual if the
capacitor bank is closed when the Daily Operations
Counter Limit is exceeded.
