Alarms should be tested in each distribution bay of the plant to verify the integrity of the
alarm bus throughout the plant.
If the distribution bays are equipped with “Bay Fuse Alarm” indicating LEDs, also verify
that this LED activates during these tests for the bay in which the alarm originates (and
not in any other).

Clear History
This feature is useful when there is a need to remove unnecessary historical data from the
controller. An example might be after installation and testing and the controller is ready
for operation. There may be history that is of no use to the customer. Also, since the
history log has a finite number of entries, user can save the history using a PC, and then
clear the logs.
