Table of Contents

For each of the 352 signals, it is also possible to select if the signal is to be used as a trigger

for the start of the Disturbance report and if the trigger should be activated on positive (1)

or negative (0) slope.

TrigDRN: Disturbance report may trig for binary input N (Enabled) or not (Disabled).

TrigLevelN: Trig on positive (Trig on 1) or negative (Trig on 0) slope for binary input N.

Func103N: Function type number (0-255) for binary input N according to

IEC-60870-5-103, that is, 128: Distance protection, 160: overcurrent protection, 176:

transformer differential protection and 192: line differential protection.

Info103N: Information number (0-255) for binary input N according to IEC-60870-5-103,

that is, 69-71: Trip L1-L3, 78-83: Zone 1-6.

See also description in the chapter IEC 60870-5-103.

Analog input signals

Up to 40 analog signals can be selected among internal analog and analog input signals.

PCM600 is used to configure the signals.

For retrieving remote data from LDCM module, the Disturbance report

function should be connected to a 8 ms SMAI function block if this is the

only intended use for the remote data.

The analog trigger of Disturbance report is not affected if analog input M is to be included

in the disturbance recording or not (OperationM = Enabled/Disabled).

If OperationM = Disabled, no waveform (samples) will be recorded and reported in graph.

However, Trip value, pre-fault and fault value will be recorded and reported. The input

channel can still be used to trig the disturbance recorder.

If OperationM = Enabled, waveform (samples) will also be recorded and reported in

NomValueM: Nominal value for input M.

OverTrigOpM, UnderTrigOpM: Over or Under trig operation, Disturbance report may

trig for high/low level of analog input M (Enabled) or not (Disabled).

OverTrigLeM, UnderTrigLeM: Over or under trig level, Trig high/low level relative

nominal value for analog input M in percent of nominal value.
