Figure 52 - Warm Start Operation
Cold Start
A Cold Start clears the data in battery backed RAM, turns all outputs off, transfers the configuration file
from flash memory to RAM and reinitializes all dynamic data.
The Cold Start procedure is flowcharted in
Figure 53. The controller initiates the Cold Start procedure:
After a power outage, when diagnostics indicate that the controller hardware and software program are
intact, but the content of the RAM database is incorrect. (See Figure 52.)
On a Mode transition from PROGRAM to RUN. (This Mode transition can be initiated by operating the
Mode switch on the controller, or by exiting the Program mode at an operator interface.)
When initiated by the user (after download with Cold Start selected, or any transition from PROGAM
Mode to RUN Mode.)
