Configuring setpoints

Use Power Monitoring Expert or ION Setup to change your meter’s setpoints.

Using the front panel

You cannot configure setpoints using the front panel.

Using ION Setup

  1. Connect to your meter in Advanced Mode.
  2. Click on the Relative Setpoint module you want to configure.

Using Vista

Open your meter in Vista and click on the Setpoints tab. Click the Setup icon. Use the switches to turn various monitoring on and off (see circled below). Click the numeric boxes to edit condition settings.

Relative Setpoint module settings

By default, the following Relative Setpoint modules are configured:

Label

Description

Over KW sd

When active, this annunciates when the total kW sliding window demand exceeds a specified amount.

Over I a

When active, this annunciates when the current on phase A exceeds a specified amount.

Over I b

When active, this annunciates when the current on phase B exceeds a specified amount.

Over I c

When active, this annunciates when the current on phase C exceeds a specified amount.

Over V unbal

When active, this annunciates if the voltage unbalance exceeds a specified amount.

Phase 1 loss, Phase 2 loss, Phase 3 loss

When active, these annunciate if the phase voltage drops below the Sag/ Swell module’s Nom Volts register by a specified amount.

V1, V2, V3 (+/- 15%) for 10m, 10s, 3s

When active, these annunciate when the phase voltage deviates from the Sag/Swell module’s Nom Volts register by a specified amount.

NOTE: There is usually no need to change any of the Relative Setpoint modules’ setup registers for normal operation of the meter.

See the ION Reference for more information on the Relative Setpoint module.

Fine tuning over condition monitoring

If you want to fine-tune over condition monitoring, the only setup registers you should change are SusUntlON and SusUntlOFF.

SusUntlON determines how long the modules wait after an over condition is detected before reporting it. This gives the monitored value a short period to correct itself before the event is registered with the module so that very brief over conditions are ignored. Similarly, SusUntlOFF is the amount of time a normal value must be present before the module considers normal operation to be restored. Both SusUntlON and SusUntlOFF values are entered in seconds.
