c) FACEPLATE (USER KEY) CONTROL
After the 30 minute interval during which command functions are permitted after a correct command password, the user
cannot open or close a breaker via the keypad. The following discussions begin from the not-permitted state.
d) CONTROL OF TWO BREAKERS
For the following example setup, the
(Name)
field represents the user-programmed variable name.
For this application (setup shown below), the relay is connected and programmed for both breaker 1 and breaker 2. The
USER 1 key performs the selection of which breaker is to be operated by the USER 2 and USER 3 keys. The USER 2 key
is used to manually close the breaker and the USER 3 key is used to manually open the breaker.
e) CONTROL OF ONE BREAKER
For this application the relay is connected and programmed for breaker 1 only. Operation for this application is identical to
that described above for two breakers.
