function uploads these files into the NGC TFCold drive. This safeguards the data
and allows for a re-start of the unit without the problems of re-configuring the NGC
should anything arise.
5.6.1 Instructions
1) While in PCCU, use the Save and Restore Utility found under File Utilities
in the Operate drop down menu or by clicking Save and Restore Utility on
the toolbar.
2) In the Save and Restore window, click Restore Station Files.
3) When the Restore Station Files window appears, verify the default name and
path for the files. Click OK. This will restore the files to the TFCold drive.
4) Perform a cold start following the instructions in the Reset Procedures
sub
section and verify the unit is functioning properly.
It may not always be desirable to restore the station files to
TFCold. Some problems addressed in the Troubleshooting
section may require a selective restore.
5.7 Reset Procedures
On occasion, it may be necessary to reset the unit. There are two types of reset
procedures: warm or cold.
5.7.1 Warm Start Instructions
A warm start occurs when the main power is removed and then re-applied while
memory backup is enabled. This does not clear the data stored in RAM. The warm
start will only reset the NGC microprocessor and not disturb any data that has
been stored in RAM. A warm start can be used when a power or communication
interruption caused the NGC microprocessor to lock-up.
1) Collect data from the unit.
2) Using the Lithium Battery Status instructions, verify the battery status is OK
before proceeding.
3) Gain access to the rear termination panel on the NGC by loosening the
countersunk hex socket locking set screw in the rear end cap using a 1/16” hex
wrench and then unscrewing the end cap.
As with all electronic components, caution should be used
when handling boards. Static electricity can potentially
damage board components, voiding any warranty.
4) To warm start the unit, depress the S1 reset switch on the termination panel.
Or, to remove the NGC from service, disconnect the power connector J1
from the board.
5) To place NGC in service, return the power connection J1 to the termination
panel.
5.7.2 Cold Start Instructions
1) On the Analyzer Operation screen, click Hold under Next Mode. When the
unit completes the current cycle and enters hold, continue to the next step.
As with all electronic components, caution should be used
when handling boards. Static electricity can potentially
damage board components, voiding any warranty.
