10-6 Testing and Troubleshooting Date Code 20080110
SEL-387E Instruction Manual
Cables: SEL-C234A for 9-pin male computer connections
SEL-C227A for 25-pin male computer connections
Step 2. Purpose: Apply control voltage to the relay, and start Access Level 0
communications.
Method: Apply control voltage to the relay. The enable target (EN) LED should
illuminate. If not, be sure that power is present. Type <Enter> from your
terminal to get the Access Level 0 response from the relay. The = prompt
should appear, indicating that you have established communications at
Access Level 0.
The ALARM relay should pull in, holding its “b” contacts open.
If the relays pull in but your terminal does not respond with the equal sign,
check the terminal configuration. If neither occurs, turn off the power and
refer to the Troubleshooting Guide later in this section.
The = prompt indicates that communications with the relay are at Access
Level 0, the first of four possible levels. The only command accepted at
this level is ACC <Enter>, which opens communications on Access
Level 1.
Note: If you are using a battery simulator, be sure the simulator
voltage level is stabilized before turning the relay on.
Step 3. Purpose: Establish Access Level 1 communications.
Method: Type ACC <Enter>. At the prompt, enter the Access Level 1 password
and press <Enter> [see PAS (PASSWORDS) in Section 7:
Communications for a table of factory default passwords]. The =>
prompt should appear, indicating that you have established
communications at Access Level 1.
Step 4. Purpose: Verify relay self-test status.
Method: Type STA <Enter>. A display similar to the screen capture following
should appear on the terminal: (Note: The current input names shown are
the default values; any inputs renamed in the Analog Input Labels settings
will appear as set.) To view a relay status report, see the example
following the discussion of Status Reporting Function in Section 5:
Metering and Monitoring.
Step 5. Purpose: View factory settings entered before shipment.
Method: The relay is shipped with factory settings; type SHO <Enter> to view the
settings. Section 6: Settings includes a complete description of the
settings.
