This option shows the status of the system memory.

To select the Program Integrity option, press
2
from Page 2 of the Commissioning Menus.
The display then shows the
status in the following format:
•
The top line shows the status of the ROM (Program Memory) and RAM (Configuration Memory).
•
The ROM status will show either ‘Program Pass’ or ‘Program Fail’ depending on the calculation of the
checksum.
Should the ROM status indicate a failure, it is important to contact the factory immediately. Please
make a note of the software version number and ROM checksum displayed.
•
The RAM status will show whether either PASS, UNLOCKED or FAIL.
If the display indicates a Configuration Memory failure, perform the following actions and recheck.
Set the memory lock switch to OPEN, select and then exit from the CONFIG option (Page 1 of the
commissioning menus, set the memory lock switch to LOCK and select NORMAL OPERATION.
Then re-check the Program Integrity.
•
The bottom line of the display shows three parameters. These are, from left to right, the software version
code (i.e. 607-D0), the ROM checksum and the RAM checksum. The ROM and RAM checksums are in
hexadecimal notation.
•
The ROM version and checksum are not alterable and should be quoted in all correspondence.
•
The RAM checksum will alter whenever the configuration is changed. For example, the figure will change
when either adding or removing devices, changing text assignments, etc.
When the configuration has been changed, the program integrity should be checked and the RAM
checksum should be recorded.
