A. Verify the Supplied IED RS 485
connections and cable connections as
shown in Figure 2.
B. B
Verify the port parameters in the
attached relay as described in Step 7.
C. Verify the ORION configuration settings
as described in Step 11 Figure 5.
D. Have the configuration settings been
downloaded to the ORION as described in
Step 15 Figure 9.
E.
A timeout has occurred. Modify the Warm
–Up and Warm Down delays in the
Modbus IED port parameterization screen
to be 10 mS less than is presently
configured. Download the new
configuration to the ORION Unit. (Step 11
Figure 5 and Step 15 Figure 9).
A. Determine that the jumper settings have
been set for RS 485 (Step 3 Figure 2)
operation.
B. .Verify that the termination resistor and the
pullup resistors are configured in the IED
protective relay (Jumpers J6 [termination],
J8 [Pullup], and J7 [Pulldown]) (Step 6).
A. Check the SCADA Port Cabling per the
Host manufacturer's specification.
B. Verify the (SCADA) Conitel Port
Configuration through the setup menu of
the CON2MOD setup utility. (Step 12
Figure 6).
C. Conitel (SCADA) Port Timeout has
occurred decrease the Warm Up and
Warm-down timeout values by 10 mS until
issue resolved.
D. Verify the Supplied IED RS 485
connections and cable connections as
shown in Figure 2 (Step 6).
E. Verify the IED port parameters in the
attached relay as described in Step 7.
D. Verify the ORION IED configuration
settings as described in Step 11 Figure 5.
E. Have the configuration settings been
downloaded to the ORION as described in
Step 15 Figure 9.
F. A timeout has occurred. Modify the IED's
Warm –Up and Warm Down delays in the
Modbus IED port parameterization screen
to be 10 mS less than is presently
configured. Download the new
configuration to the ORION Unit. (Step 11
Figure 5 and Step 15 Figure 9).
G. If the communications between the IED
