Step 5. Save the new settings in the
ACSELERATOR software. On the
File menu, click Save.
Step 6. Upload the new settings to the SEL-421 Relay. On the File
menu, click Send. The
ACSELERATOR software prompts you
for the settings class you want to send to the relay, as shown in
the Group Select dialog box of Figure 6.15. Click the check
box for Group 1 and for Report. Click OK. The

software responds with a Transfer Status dialog box as in
Figure 6.15. If you see no error message, the new settings are
loaded in the relay.
NOTE: The Relay Editor dialog boxes
shown in Figure 6.15 are for the
SEL-421 Relay. The SEL-421-1 Relay
dialog boxes are similar.

Figure 6.5 on page 6.12 and Secondary Circuits on page U.2.5
in the User’s Guide).
