LED. All other (undefined) combinations of the binary input signals (0 0 or 1 1) are indicated by a
yellow LED.
The Status LED on LMI dialog box is saved by clicking OK. The dialog box LMI LED configuration is
active again and a print of the LED labels can be started by clicking Print Labels now. Before initiating a
print job, the Print Range as well as the Label Orientation shall be adjusted.

Analogue inputs

Bay Units
The currents measured by the four analogue inputs are always recorded. The five voltage inputs may
only be recorded providing they have been licensed and engineered (optional).
The recording time is doubled if the voltage channels are not activated.
Central Unit
The differential and restraint currents and in addition the phase angle difference (hereinafter referred to
as phase difference) of the currents are recorded per phase (L1..L3, L0) and bus zone. In the event that
several bus zones are interconnected to (L1..L3, L0) and bus zone. In the event that several bus zones
are interconnected to one protection zone, each bus zone shows the same measurement values.
The phase difference is only recorded, if it is enabled in the Recording tab of the CU disturbance
recorder configuration (see
The following diagram is an example of a phase difference record where no BBP trip occurred (since
phase difference value is constantly above the trip range).
