Working with Setpoints & Setpoints Files
FAST PATH:
When a settings file is being uploaded to a device, the DEVICE IN SERVICE state (Setpoints >
Device > Installation) switches to "Not Ready" for the duration of the upload. This ensures
that all new settings are applied before the device is operational. Settings file upload
operations include both 1) Enervista 8 Series Setup software menu option "Write Settings
File to Device" and 2) saving Logic Designer changes online.
Individual setting changes from the device front panel or Enervista 8 Series Setup software
Online Window do not change the DEVICE IN SERVICE state.
Engaging a Device The EnerVista 8 Series Setup software may be used in on-line mode (relay connected) to
directly communicate with a relay. Communicating relays are organized and grouped by
communication interfaces and into sites. Sites may contain any number of relays selected
from the product series.
Entering Setpoints The System Setup page is used as an example to illustrate entering setpoints. In this
example, we are changing the voltage sensing setpoints.
1. Establish communications with the relay.
2. Select the Setpoint > System > Voltage Sensing menu item.
3. Select the Aux. VT Secondary setpoint by clicking anywhere in the parameter box. This
displays three arrows: two to increment/decrement the value and another to launch
the numerical keypad.
4. Clicking the arrow at the end of the box displays a numerical keypad interface used to
enter values within the setpoint range displayed near the top of the keypad: Click = to
exit from the keypad and keep the new value. Click on X to exit from the keypad and
retain the old value.
