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 Enabled or
Disabled . If Disabled is selected, note that no disturbance report is registered, and none
sub-function will operate (the only general parameter that influences Sequential of
events (SOE)).
Operation = Disabled :
• Disturbance reports are not stored.
• LED information (yellow - pickup, red - trip) is not stored or changed.
Operation = Enabled :
• Disturbance reports are stored, disturbance data can be read from the local HMI
and from a PC for example using PCM600.
• LED information (yellow - pickup, 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
Enabled .
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.
The IED flash disk should NOT be used to store any user files. This
might cause disturbance recordings to be deleted due to lack of disk
space.
