Troubleshooting
Symptom
SEL-2032 does not communicate with connected IED.
Probable Cause
Port and baud rate settings of PC may be incorrect.
Corrective Action
Set the port and baud rate settings of the PC terminal to match
the SEL-2032
. If you do not know what the settings are, install the
baud rate jumper and then make the settings
.
Symptom
SEL-2032 does not communicate with connected IED.
Probable Cause
Serial cable damaged or wrong cable connected.
Corrective Action
Inspect the cabling for damage and proper connection. Make
sure appropriate cable is connected (see Ta ble 2.4 ).
Symptom
SEL-2032 does not communicate with connected IED.
Probable Cause
Port settings do not match the IED settings.
Corrective Action
Using the SET command, set the port settings
to match those of the IED connected to the port.
Symptom
SEL-2032 does not communicate with connected IED.
Probable Cause
Port may be locked up due to hardware handshaking
Corrective Action
Reset IED and/or reset port settings
using SET P and accepting settings.
Symptom
SEL-2032 does not communicate with connected IED.
Probable Cause
Component failure. Port F LED(s) illuminates
but others do not illuminate when port is addressed.
Corrective Action
Remove power and contact the factory.
Symptom
No prompt.
Probable Cause
Incorrect baud rate.
Corrective Action
Verify baud rate in communication software.
Default baud rate for the SEL-2032 is 2400.
Symptom
SEL-2032 not accepting REC command
Probable Cause
Not in the SELBOOT mode
Corrective Action
Enter L_D to get into the SELBOOT mode. When in SELBOOT
mode, the prompt is an exclamation point.
Symptom
Protocol card not accepting REC n command
Probable Cause
SEL-2032 and protocol card are not in the SELBOOT mode
Corrective Action
Enter L_D to get into the SELBOOT mode. When in SELBOOT
mode, the prompt is an exclamation point. Also see next problem to
force SEL
BOOT mode.
Symptom
Unknown communication problem
Probable Cause
1. Incompatible firmware in SEL-2032 and protocol card.
2. Device not in SEL
BOOT mode.
Corrective Action
Force SEL-2032 into SELBOOT mode using the following
procedure:
Cycle Power on the SEL-2032 while depressing the LED TEST
button on the SEL-2032.
