Advanced Meter Setup Menu 9300 Series User’s Guide
Page 32 Chapter 2 - Using The Front Panel
The remaining Power Meter module setup options and their default values are
given in the online ION Programmer’s Reference. In most cases you can leave them
at their default settings and the meter will function properly.
Sag/Swell Module Settings (9350)
You must set the Sag/Swell module’s Nom Volts setup register to a voltage that
represents the nominal voltage for your power system (for example, 120). If the
Sag/Swell module’s Nom Volts setup register is set to zero, all Sag/Swell module
functions are disabled.
CAUTION
The
Nom Volts
setup register MUST be set to your primary power system voltage, or the Power Quality
features of the 9350 meter will not properly function.
.
1The ANSI C84.1 1989 standard recommends a temporary overvoltage limit of 106% for Range B
voltage levels, and a temporary undervoltage limit of 88% for load voltages and 92% for the service
entrance.
2The primary power system voltage is sometimes different than the PT Primary setup register value; i.e.
when the PT Primary is used to indicate winding ratio rather than primary voltage.
Advanced Meter Setup Menu
The Advanced Meter Setup menu provides access to the setup registers of every ION
module in the meter. To access this menu screen, select ADV METER SETUP from the
Setup menu. Follow this procedure to access a setup register:
1. From the Feature Manager screen, select the module’s type.
2. Select the module you want to configure from the list of available modules.
3. From the list of the module’s setup registers, select the one you want to
configure.
4. Edit the value of the register (see “Editing Registers” on page3–28).
You may be prompted to enter your password (see “Front Panel Password
Security” on page 3–28). Select YES to the next prompt to change the value of the
register. Select NO if you want to leave the screen without making any changes.
Refer to the online ION Programmer’s Reference for complete details on each setup
register’s function.
Register Default Description
Swell Lim 1106 The limit a monitored voltage must exceed in order for the meter to
classify it as an overvoltage condition.
Sag Lim 188 The limit a monitored voltage must fall below in order for the meter
to classify it as an undervoltage condition.
Nom Volts 20The primary power system voltage (line-to-line voltage for Delta
systems, and line-to-neutral voltage for Wye systems).
