a) INTRODUCTION
The F60 can interface with associated circuit breakers. In many cases the application monitors the state of the breaker, that
can be presented on faceplate LEDs, along with a breaker trouble indication. Breaker operations can be manually initiated
from faceplate keypad or automatically initiated from a FlexLogic operand. A setting is provided to assign names to each
breaker; this user-assigned name is used for the display of related flash messages. These features are provided for two
breakers; the user can use only those portions of the design relevant to a single breaker, which must be breaker 1.
For the following discussion it is assumed the
setting is "Enabled" for each breaker.
