6. Function Keys
Four function keys are typically used for quick and simple execution of frequently
performed actions. The function of the keys can be defined (programmed) by the
user. For example, the F1 key could be set to activate the display of operational
reports, and the F2 key could be set to cause the display of operating values. The
keys can also be programmed for control purposes. For example, the F3 key could
be programmed to initiate a close command for a circuit breaker, while the F4 key
could be programmed to initiate a trip command. Next to the keypad, a labeling
strip is provided on which the user-specified key functions can be written.
