Function Keys
Pressing F1 confirms settings changes (when the equipment asks for confirmation
of the changes) or activates the default table of settings.
The F2 key is used to refer to information about the current measurements,
voltages and powers, the status of the Recloser can be changed, the last trip
indication reset, LEDs reset and Recloser counters. The entire sequence of
actions using Function Key F2 is explained in the following section.
The F3 key is used to change the operative subsystem between protection
[PRO]
and control
[CON]
. It is possible to display on the screen information about the
event record, and the octets that contain the function codes that the
corresponding event has generated.
The F4 key is used to cancel the changed settings (when the equipment asks for
confirmation of the changes) and to cancel the activation of the default table of
settings. F4 can, also, be used to reset the terminal.
CAUTION: A password and confirmation is required before proceeding with
the reset function, because all settings could be lost, making the activation
of the protection dangerous.
In the screens corresponding to the fault information, F4 is used to access the
information generated by the trip and the units that tripped to clear the fault.

measurements, etc. This direct access consists of pushing successively the identification
numbers that are displayed on the screen before each setting, or within a corresponding setting.
