Table 6-3. R-NAC Card-Related Events
R-NAC Card-Related Output Events
For the following R-NAC-related events, # is the logical address of the R-NAC
Expansion Card as defined in the configuration. The numbers “1”, “2” and “3”
refer to the three (3) circuits available on each R-NAC Expansion Card.
Error Message Probable Cause Corrective Action
AR#:1 OPEN CIRCUIT TROUBLE On
AR#:2 OPEN CIRCUIT TROUBLE On
AR#:3 OPEN CIRCUIT TROUBLE On
Open circuit in field wiring connected to
expansion R-NAC Circuit 1, 2 or 3
(configured as release circuit).
• Look for discontinuity in R-NAC
circuit field wiring. Refer to
Section 2-8.7.2
• Check for missing 10k end-of-line
resistor.
AR#:1 SHORT CIRCUIT TROUBLE On
AR#:2 SHORT CIRCUIT TROUBLE On
AR#:3 SHORT CIRCUIT TROUBLE On
Short circuit in field wiring connected
to expansion RNAC Circuit 1, 2 or 3
(configured as release circuit).
• Troubleshoot R-NAC circuit wiring by
breaking-up circuit to isolate short
circuit to specific leg.
• Look for discontinuity in R-NAC
circuit field wiring. Refer to
Section 2-8.7.2
AR#:1 ACTIVATION FAILURE On
AR#:2 ACTIVATION FAILURE On
AR#:3 ACTIVATION FAILURE On
The activation of an R-NAC circuit
(configured as release circuit) has failed
due to overcurrent or other problem.
• Troubleshoot R-NAC circuit wiring by
breaking-up circuit to isolate short
circuit to specific leg.
• Look for discontinuity in R-NAC
circuit field wiring. Refer to
Section 2-8.7.2
SG#:1 OPEN CIRCUIT TROUBLE On
SG#:2 OPEN CIRCUIT TROUBLE On
SG#:3 OPEN CIRCUIT TROUBLE On
Open circuit in field wiring connected to
expansion R-NAC Circuit 1, 2 or 3
(configured as NAC).
