Parameter Description
Display Scroll Time *
The number of seconds (1 to 15) that each item is to be
displayed before the next item appears.
Cold Load Pickup Time *(CLPU)
The number of minutes (0-255) before demand
calculations are restarted after a recognized power
outage occurs. Setting this value to zero will cause
demand calculations to start immediately following a
power outage.
Power Outage Length Prior to CLPU *
The number of minutes (0 to 255) that power must be
out for the CLPU to take effect. Defining this value as
zero will cause CLPU to be activated after any
recognized power outage.
Normal Mode Demand Interval Length
The time in minutes (1 to 60) that each demand interval
lasts before a new interval begins. Valid interval lengths
are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 minutes.
Test Mode Demand Interval Length*
The time in minutes (1 to 60) that each Test mode
demand interval lasts before a new interval begins. Valid
interval lengths are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30,
and 60 minutes.
Normal Mode Number of Subintervals*
The interval length divided by the sub-interval length is
equal to the number of subintervals. Valid entries are
from 1 to 10 and must be evenly divisible into the
demand interval length. For block demand, the number
of subintervals is 1.
Test Mode Number of Subintervals*
The interval length divided by the sub-interval length is
equal to the number of subintervals. Valid entries are
from 1 to 10 and must be evenly divisible into the
demand interval length. For block demand, the number
of subintervals is 1.
Register Full Scale
A kW demand value that defines the maximum rated
demand for a particular meter installation. Valid entries
range from 0 to 999999.
Test Mode Timeout
The number of minutes the meter will remain in Test
mode before exiting to Normal mode. This timeout
function is active when Test mode has been activated via
remote communications. Valid entries range from 1 to 99
minutes.
Operating Frequency*
The operating frequency must be programmed to 50 Hz
or 60 Hz line operation.
Line or Crystal Sync*
The real time clock can be synchronized off the input line
frequency or the internal crystal.
