Disturbance recorder
The sequence number of the recordings is a specific parameter for the dis-
turbance recorder and is used to identify the different recordings. By com-
bining the date and the sequence number for a recording, the recording can
be uniquely identified. The combined setting and service value for the
sequence number is found in the menu tree under:
ServReport
DisturbReport
SequenceNo
The read value on the man-machine interface (MMI) display is the
sequence number that the next recorded disturbance receives. The number
is automatically increased by one for each new recording and is reset to
zero at each midnight. The sequence number can also be set manually.
Evaluation of the results from the disturbance recording function requires
access to an SMS workstation either permanently connected to the termi-
nal or temporarily connected to the serial port on the front. These software
packages must be installed in the workstation:
Package: For:
SMS-BASE Common functions
RECOM Collection of the disturbance data
REVAL Evaluation and printouts of the recorded data
It could be useful to have a printer for hard copies. The behavior of the
disturbance recording function can be checked when protective functions
of the terminal are tested.
When the terminal is set to operate in test mode, there is a separate setting
for operation of the Disturbance report, which also affects the disturbance
recorder.
A manual trig can be started any time. This results in a snapshot of the
actual values of all recorded channels.
