The analog signals are presented only in the disturbance recording, but they affect the entire
disturbance report when being used as triggers.
Binary signals
Up to 128 binary signals can be selected to be handled by disturbance report. The signals can be
selected from internal logical and binary input signals. A binary signal is selected to be recorded
when:
• the corresponding function block is included in the configuration
• the signal is connected to the input of the function block
Each of the 128 signals can be selected as a trigger of the disturbance report (
Operation—>TrigDR =Enabled ). A binary signal can be selected to activate the red LED on the local
SetLED = Enabled ).
HMI (
The selected signals are presented in the event recorder, sequential of events and the disturbance
recording. But they affect the whole disturbance report when they are used as triggers. The
indications are also selected from these 128 signals with local HMI
Trigger signals
The trigger conditions affect the entire disturbance report, except the sequential of events, which
runs continuously. As soon as at least one trigger condition is fulfilled, a complete disturbance
report is recorded. On the other hand, if no trigger condition is fulfilled, there is no disturbance
report, no indications, and so on. This implies the importance of choosing the right signals as
trigger conditions.
A trigger can be of type:
• Manual trigger
• Binary-signal trigger
• Analog-signal trigger (over/under function)
Manual trigger
A disturbance report can be manually triggered from the local HMI, PCM600 or via station bus (IEC
61850). When the trigger is activated, the manual trigger signal is generated. This feature is
especially useful for testing. Refer to the operator's manual for procedure.
Binary-signal trigger
Any binary signal state (logic one or a logic zero) can be selected to generate a trigger (
Trig on 0/Trig on 1). When a binary signal is selected to generate a trigger from a logic zero, the
selected signal will not be listed in the indications list of the disturbance report.
Analog-signal trigger
All analog signals are available for trigger purposes, no matter if they are recorded in the
disturbance recorder or not. The settings are
UnderTrigLe .
The check of the trigger condition is based on peak-to-peak values. When this is found, the
absolute average value of these two peak values is calculated. If the average value is above the
threshold level for an overvoltage or overcurrent trigger, this trigger is indicated with a greater
than (>) sign with the user-defined name.
If the average value is below the set threshold level for an undervoltage or undercurrent trigger,
this trigger is indicated with a less than (<) sign with its name. The procedure is separately
performed for each channel.
