Working with setpoints and setpoint files
Engaging a device The 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 will be used as an example to illustrate the entering of setpoints. In
this example, we will be changing the current sensing setpoints.
1.
Establish communications with the relay.
2. Select the Setpoint > Configure > CT-VT menu item.
3. Select the CT Primary setpoint by clicking anywhere in the parameter box. This will
display 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 that
allows the user to enter a value 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.
5. For setpoints requiring non-numerical pre-set values (e.g. CT Primary below), clicking
anywhere within the setpoint value box displays a drop-down selection menu arrow.
Select the desired value from this list.
