poor electrical environment of a factory. Should some
unforeseen circumstances cause the data in RAM to be
corrupted or lost, a CLEAR-RESTART procedure is provided
that will retrieve the parameter table stored in the EEPROM
and copy it into RAM memory for use. If you make changes to
the PARAMETER table, these changes reside only in RAM and
may be lost in the event of an unforeseen computer
malfunction. To insure that your changes are saved for
future runs, it is necessary to move this information from
RAM to the EEPROM.
NOTE: The battery used for backup is a lithium battery that
is part of an I.C. chip on the board. It has an expected 10
year life and is not easily accessible for replacement.
Should it fail, we suggest that it be replaced at our
factory.
*23 Press (*,2,3) to move the PARAMETER table from RAM to
EEPROM. This information is then available for retrieval
using the CLEAR routine (press CE key on Power Up) or by
using the *32 function described next.
*32 Press (*,3,2) to move EEPROM information to RAM. This is
useful for retrieving correct information that you may have
stored earlier in the EEPROM. Also, if you have been making
changes to RAM tables and now wish to restore all parameters
to what they were at power up, this is the function to use.
*25 Press (*,2,5) to check the ROM-CHECK flag. Whenever your
controller is on, the processor is continuously performing
an integrity check of the ROM program chip supplied with the
unit. Each complete scan of the program takes about one
minute. If any single check reveals an incorrectly set bit,
the ROM CHECK flag is turned on. This flag is checked every
time you power up. If the flag has been set the display
will say (ROM BAD ), followed by the date and time of the
last check that was found bad. If the flag has not been
set, (ROM OK ) will be displayed. To turn the flag off, you
must select this option, (*25), and, with (ROM BAD)
displayed, press the "CE" key. This will clear the flag and
it will remain off until another error is detected. The
seriousness of the problem will be somewhat indicated by the
date and time of the last bad check and how frequently you
find it necessary to turn this flag off. Even with an
error, your controller may still work perfectly. However,
we suggest you request a new program chip from us as soon as
possible.
*33 Press (*,3,3,) to turn on a special alarm condition. Press
* to toggle between (AL STD) and (AL-BATCH). If you are
running using the BATCH key, and (AL-BATCH) is selected,
then the ALARM will sound when a batch is completed.
*44 This flag for SPECIAL APPLICATIONS ONLY.
Press (*,4,4) to tell the controller to end a cycle when the
weigh bin is FULL. Use the * key to toggle between (END
EMTY) or (END FULL).
