While you have the relay global settings on the screen, verify that:
TIME2=0
AUTO=2 or 3 (setting 2 is for Port 2 and setting 3 is for both Ports 1 and 2)
These settings allow the SEL-2020 to continue to receive automatic messages from the relay
without the port timing out. If these two settings are not as shown above, go to Access Level
2 and use the relay SET command to change them.
Return the relay to Access Level 0 and quit transparent communication using the default
disconnect sequence or key stroke <CTRL-D>.
Note: After transparent communications with the relay, the SEL-2020 will reissue the
STARTUP string to the relay to return it to the access level needed for proper
operation. If you change a relay password, modify the port's startup string to match. If
you use an SEL-501 Relay and change one of the relay type settings, re-configure
afterwards so that the SEL-2020 maintains a correct target list.
You should see the following:
=>>QUIT<ENTER>
QUIT<ENTER>QUIT<ENTER>
QUIT<ENTER>

4. Use the TOGGLE command, as shown in the following screen image, to send the date
message previously defined as MESG1 in the SEL-2020 As shown here, you toggle the state
of the D1 element to trigger the associated message MESG1. The SEL
OGIC Control
Equation in ISSUE1 normally does this, but the TOGGLE command lets you test the process
without waiting for the SEL
OGIC Control Equation condition to become true.
