Set Phase Loss:
VOLTS - Phase Loss Voltage: The fraction of the system
voltage below which Phase Loss Alarm is on. For system
types with neutral, the Line to Neutral voltage is also
calculated and tested. If the System Voltage is 600 and the
fraction is set to 0.10, then the Phase Loss threshold will be
60 volts.
IMBAL - Phase Loss Imbalance: The fractional difference
in Line to Line voltages above which Phase Loss Alarm is
on. For system types with neutral, the Line to Neutral
voltages are also tested. For system types 1+N (10) and 2
(11) , imbalance is not tested.
Set Pulse:
The System Type , CT size, PT Ratio, and System Voltage must
all be configured before setting the Pulse Energy. If any of these
parameters are changed, the meter will hunt for a new Pulse
Duration, but will not change the Pulse Energy. If it cannot find a
solution, the meter will display the wrench, show "ConF" in the
ALARM -> PULSE screen, and enable Energy pulse output
configuration error bit in the Modbus Diagnostic Alert Bitmap (if
equipped).
Wh/P - Set Pulse Energy: In Watt Hours (& VAR Hours, if
present) per Pulse. When moving down to a smaller energy, the
meter will not allow the selection if it cannot find a pulse duration
that will allow the pulse output to keep up with Theoretical
Maximum System Power (see S_PWR screen). When moving
up to a larger energy, the meter will jump to the first value where
it can find a valid solution.
mS/P – Minimum Pulse Duration Time: This read only value
is set by the meter to the slowest duration (in mS per closure)
that will keep up with the Theoretical Maximum System Power.
The open time is greater than or equal to the closure time. The
maximum Pulses Per Second (PPS) is shown in yellow.
Set Demand Interval:
INTRV - The number of Sub-Intervals (1 to 6) in a
Demand Interval. Default is 1 (block demand).
SEC - Sub-Interval length in seconds. Default is
900 (15 minutes). Set to 0 for external sync-to-
comms (Modbus units only).
