d) ENTERING SETPOINTS
The following example illustrates how setpoints are entered and edited with the 489PC software.
1. Select the Setpoint > System Setup menu item.
2. Click the Current Sensing tab to edit the S2 SYSTEM SETUP Ö CURRENT SENSING setpoints. 489PC displays the follow-
ing window:
3. For setpoints requiring numerical values, e.g. PHASE CT PRIMARY , clicking anywhere within the setpoint box launches a
numerical keypad showing the old value, range, and setpoint value increment.
4. Alternately, numerical setpoint values may also be chosen by scrolling with the up/down arrow buttons at the end of the
setpoint box. The values increment and decrement accordingly.
5. For setpoints requiring non-numerical pre-set values (e.g. GROUND CT TYPE above), clicking anywhere within the set-
point value box displays a drop down selection menu.
6. For setpoints requiring an alphanumeric text string (e.g. message scratchpad messages), the value may be entered
directly within the setpoint value box.
e) UPGRADING SETPOINT FILES TO A NEW REVISION
It may be necessary to upgrade the revision code for a previously saved setpoint file after the 489 firmware has been
upgraded.
1. Establish communications with the 489 relay.
2. Select the Actual > Product Information menu item and record the Flash Revision identifier of the relay firmware.
For example, 32H150A8.000, where 150 is the Flash Revision identifier and refers to firmware revision 1.50.
