8 Program Integrity Option
•
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:
*Program Pass Config Memory UNLOCKED *
607-D0 50579961 DD10FFD5
•
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 Config 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.
