Chapter 2
Operating the Control
2-42
Sometimes you must perform a reform memory operation on the control to
clear memory. Typically, you do this when:
the amount of RAM memory that can be used by PAL is changed in
AMP
a new PAL program has been sent to the control (downloading PAL
does not always make it necessary to format)
battery power was lost when the 9/240 control was turned off
after 5 days’ backup by the supercapacitor, the optional lithium battery
takes over; this provides 2 years of continuous, accumulated backup for
the standard 9/260 or 9/290 control, and 1 year for the 9/260 or 9/290
with extended program storage
Important: You must format any time the control displays the error
message “MEMORY CRASH -- REFORMAT.”
You can also perform this operation if you want to delete all part programs
in control memory.
After you perform a format operation, it is not necessary to re-install AMP
or PAL.
ATTENTION: The reform memory function erases all part
programs that are stored in control memory. This includes
programs in both the main and protected program directories.
You can back up these programs to ODS or to another peripheral
device before reformatting as described in chapter 6 and 9.
To reformat control memory and delete all programs stored in memory,
follow these steps:
1. Press the {PRGRAM MANAGE} softkey.
