◆ Revenue Measurements Scaling
By clicking on Secondary Units (“1:1”) this control object lets the meter display
and record Secondary values for kW, kVAR, and kVA (values not scaled with
PT and Ct ratios). By default, the meter displays Primary values (values that
using Ct, and PT scaling) for these revenue quantities.
◆ Peak Demand Reset
The Peak Demand Reset control object allows you to clear the peak demand
values logged in the meter. When the meter is in T
EST mode, this object clears
Revenue Test Mode demand parameters.
◆ Master Reset
The Master Reset control object allows you to clear all the cumulative and
derived quantities from the meter (including demand, peak demand, energy,
revenue, and Revenue Test Mode parameters). A master reset also clears the
meter’s Event log.
C AUTION
The Master Reset operation will clear all billable quantities from the meter. The Master Reset operation
will also clear the logged data from the meter’s Event log.
◆ Report Log Enable
The Report Log Enable object allows you to disable the data recorder that is
factory configured to work with Reporter.
Disabling this recorder reduces the
processing load on the meter and the network (and the Log Server in
particular).
You should only consider performing this action if the Reporter is not present
with your version of ION Enterprise. For more information about Reporter,
consult the online ION Enterprise Help.
Setpoints
The Setpoints diagram uses setpoints to monitor kW demand, over current and
voltage unbalance levels. Vista annunciates warnings if any of the values match or
exceed specified upper limits for 30 seconds or longer. Users with Level 3 authority
can define the setpoint limits. All status indicators read “N
OT A VAILABLE ” when
monitoring is disabled.
Over kW Sliding Window Demand Monitoring
◆ Over kW demand monitoring is disabled by default.
◆ To set the upper kW demand limit, enter the total number of kW that should be
considered as an over demand condition.
Per Phase Over Current Monitoring
◆ Over current monitoring is disabled by default.
◆ To set the over current limits, enter the total number of Amps that should be
considered as an over current condition.
