All messages are displayed on a 2 × 20 backlit liquid crystal display (LCD) to make them visible under poor lighting condi-
tions. While the keypad and display are not actively being used, the display will default to user-defined messages. Any high
priority event driven message will automatically override the default message and appear on the display.
a) INTRODUCTION
The F60 can interface with associated circuit breakers. In many cases the application monitors the state of the breaker,
which 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 may 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.
FUNCTION

tion. If the mode is selected as one-pole, all three breaker pole states must be input to the relay. These inputs must be in
agreement to indicate the position of the breaker.
