Messages
Setpoint P5 for Wye-Delta or P13 for solid state can be set to establish what message is shown on
the LED. Selecting meter display “0” (which is the default) will display the active status message
as shown in Table 27 or Table 28, except if there is a fault (requiring a message) or some other
information has been requested.
Alternatively, parameter P5 or P13 can be set to select a message (1 to 19 as shown in Table 29).
