INTRODUCTION
This section contains information on the LED error codes, mis-
cellaneous LED states, and diagnostic functions. Table
5-1
lists MFP module error codes, their meaning, and possible cor-
rective actions. Table
5-2 lists all other possible LED states.
The flowcharts in Figures 5-1 and 5-2 provide a quick refer-
ence guide to the front panel error codes and possible correc-
tive actions.

LED
8 7 6 5 4 3 2 1
Condition Corrective Action
01 0 0 0 0 0 0 0 1 NVRAM memory
checksum error Initialize NVRAM. If error recurs,
replace the MFP module. If error recurs
call Elsag Bailey field service.
02 0 0 0 0 0 0 1 0 Analog input calibration
error Check status bytes 4 and 5 of your
IMCIS02, IMASO01, or IMASO03 mod-
ule for an invalid reference.
03 0 0 0 0 0 0 1 1 Auxiliary module status
bad Check the status bytes of the auxiliary
module for more information.
05 0 0 0 0 0 1 0 1 Configuration error
(undefined block is
referenced) Check the configuration for any faulty
block references and correct any
found. Execute the configuration after
making the corrections.
06 0 0 0 0 0 1 1 0 Configuration error (data
type mismatch) Check the configuration for any com-
mand referencing an invalid data type.
Execute the configuration after making
the corrections.
08 0 0 0 0 1 0 0 0 Trip block activated Review the configuration to determine
why the TRIP function code in the con-
figuration has stopped the MFP mod-
ule.
0B 0 0 0 0 1 0 1 1 NVRAM memory
initialized Confirm that NVRAM is initialized; no
action is required.
0C 0 0 0 0 1 1 0 0 NVRAM memory opened
for write operation Initialize the NVRAM memory. If the
error recurs, replace the MFP module.
If error recurs call Elsag Bailey field
service.
0D 0 0 0 0 1 1 0 1 Redundancy link
communication error Check the cable connection between
primary and secondary MFP modules.
Check the cable connection from MFP
module to the termination unit or mod-
ule.
0E 0 0 0 0 1 1 1 0 Redundant module IDs
are the same Place pole 8 of dipswitch SW4 in the
opposite position of dipswitch SW4
pole 8 of the primary module.
