42    Control Modules—Network Control Module 200 Series

•

 

If possible, test the connections by installing a known functioning
NCM module into the slot.  During this procedure, disconnect the
NCU from the N1 LAN (or ensure, via NCSETUP, that the node
address of the functioning NCM will not conflict with any other
address on the network).

-

A functioning NCM verifies the connection.  Replace the
suspect NCM.

-

If a functioning NCM fails in the slot, the problem may reside
in the Power Supply Module or NCU/NEU base frame.  Refer
to the Network Control Unit/Network Expansion Unit
Technical Bulletin (LIT-636020), Troubleshooting Procedures
section for those units.

2.

If the NCM powers up with 

88

 displayed, and remains in that state

with the power LED Off, the NCM is not receiving a power-on reset
signal from the power supply.

•

 

Ensure that the +5 VDC LED is lit on the power supply module.

•

 

Follow the procedure in the Step 1 to determine if the fault lies in
the NCM, base frame connection, or power supply module.

3.

If the NCM displays an 

08

 error, 50/60 Hz line frequency is not

present.  Follow the procedures outlined in Step 1 to determine if the
NCM, base frame, or power supply module is at fault.

Power (Battery Submodule)

Evidence of a failed battery is the NCM losing memory when power is
cycled.  (To replace the battery, or review the replacement timetable, see
the Service section of this document.)

There are no internal self-tests for the battery backup submodule.  The
tests presented below isolate the problem to the battery or the battery
charger.  A quick preliminary test is offered for both the battery and
charger, followed by more extensive tests if the problem is not discovered.

1.

Battery Submodule (preliminary)

•

 

Unplug the battery submodule and inspect the connectors to ensure
that the connector pins or wires have not been bent, broken, or
pulled out.  Power can remain On for the NCM when you remove
the battery submodule.

•

 

Measure the open circuit voltage across the first two pins from the
left at the connector of the battery submodule (Figure 29).  The
value should read between 6.7 and 7.5 VDC.  A good battery
should never read less than 5.5 VDC.  Voltages below this are
often due to battery failure or extensive discharge.
