To perform basic configuration, set the primary and secondary voltage
and current ratings of your PTs (if used) and CTs. If your system
configuration includes a neutral current CT, you will need to
separately configure the I4 CT ratio.
•
PT primary: range 1 to 10,000,000, default 480
•
PT secondary: range 1 to 600, default 480
•
CT primary: range 1 to 10,000,000, default 5
•
CT Secondary: range 1 to 5, default 5
•
I4 primary and I4 secondary: same as CT primary and secondary
For direct connection to power systems of 600 V, set the PT ratio to
600:600. For a 480 V system, set the PT ratio to 480:480.
Nominal system voltage (M6, M8 only)
The M6 and M8 models use the nominal voltage setting for calculating
the default sag and swell setpoint high and low limits. For Wye and
single-phase wiring modes, set this value to the PT primary-side
nominal line-to-neutral. For all other wiring modes, set this parameter
to the PT primary-side nominal line-to-line voltage. Range 1 to
10,000,000, default 480.
Refer to the Powermonitor 3000 Installation Instructions, publication
1404-IN007 for information on selecting and installing PTs and CTs.
Advanced Device Configuration
A number of parameters are grouped into Advanced Configuration,
including the
Password , demand and projected demand setup, relay
and KYZ pulse operation setup, metering accuracy options, date/time
and Display Module scrolling rate. To perform advanced configuration
using the Display Module, navigate through these menus:
PROG.
>
PASS? > CONFIGURATION > ADVANCED . You may also set the
advanced device configuration via communications by writing to
Table A.6.
TIP
When setting a parameter, you may press and hold
the up arrow or down arrow key for a few seconds
to increase the rate the value increments or
decrements.
