Flashing light Internal failure
Dark No power supply
Yellow LED:
Steady light Triggered on binary signal N with SetLEDx = Start (or Start and
Trip)
Flashing light The IED is in test mode
Red LED:
Steady light Triggered on binary signal N with SetLEDx = Trip (or Start and
Trip)
Flashing The IED is in configuration mode
Operation
M12179-82 v6
The operation of Disturbance report function DRPRDRE has to be set On or Off. If
Off is selected, note that no disturbance report is registered, and none sub-function
will operate (the only general parameter that influences Event list (EL)).
Operation = Off:
• Disturbance reports are not stored.
• LED information (yellow - start, red - trip) is not stored or changed.
Operation = On:
• Disturbance reports are stored, disturbance data can be read from the local
HMI and from a PC for example using PCM600.
• LED information (yellow - start, red - trip) is stored.
Every recording will get a number (0 to 999) which is used as identifier (local
HMI, disturbance handling tool and IEC 61850). An alternative recording
identification is date, time and sequence number. The sequence number is
automatically increased by one for each new recording and is reset to zero at
midnight. The maximum number of recordings stored in the IED is 100. The oldest
recording will be overwritten when a new recording arrives (FIFO).
To be able to delete disturbance records, Operation parameter has
to be On.
The maximum number of recordings depend on each recordings
total recording time. Long recording time will reduce the number of
recordings to less than 100.
