9. Troubleshooting
This table is a list of troubleshooting tips specific to the CIB module. For
additional troubleshooting tips, refer to the troubleshooting section found in the
Monitoring and Control Network System Manual, reference 1.
Due to the high percentage of surface-mount components, the CIB is treated as a
field replaceable unit. If any system problems are the result of a malfunctioning
CIB unit, the entire unit must be replaced and returned for repair.
PROBLEM CAUSE
Transmitter steering
information is not displayed
on the user interface
OR
The active transmitter cannot
be selected from the user
interface
Verify that the CIB’s OPTION switch 3 is in the UP position to
enable transmitter status monitoring and control. If not, set the
switch UP and reset the CIB.
Refer to the TIB module hardware reference manual to verify
that the TIB is setup correctly.
CIB Indication is Erratic CIB is set for Transmitter Indication and a TIB unit is not
connected.
Either connect a TIB unit (and address it for the CIB address and
its own address) or switch the CIB’s Option 3 Switch DOWN
and reset the CIB.
Data from CIB changes,
when comparator lines are
static For instance, one CIB may say a receiver is Voted, while the
other says it is Disabled. You will see the indication change
between Voted and Disabled.
You probably have multiple CIBs programmed for the same
Group/Module address. Reset the CIB addresses and reset the
appropriate CIBs.
The ACT LED on the CIB is
off This is a normal condition if there is no HIB or IIB accessing the
CIB at any given time.
Fail or Error indication on
PC when Digitac comparator
votes in Coded mode Improper settings on Option Switches.
Re-set switches for Digitac: SW 1 Down SW 2 Up
and reset the CIB module. See Section 3.7, Operation With a
Digitac Comparator for more details.
