binary signals and the dates and times at which recording started. Any binary signal shown in
Appendix B can be assigned by signal setting of disturbance record. The default setting of binary
signal is shown in Appendix H.
The name of binary signal can be set by RSM100. Maximum 22 characters can be set, but LCD
displays up to 11 characters of them. Therefore, it is recommended the maximum characters are
set. The set name can be viewed on the Setting(view) screen.
The LCD display only shows the dates and times of disturbance records stored. Details can be
displayed on the PC. For how to obtain disturbance records on the PC, see the PC software
instruction manual.
The pre-fault recording time is fixed at 0.3s and the post-fault recording time can be set between
0.1 and 3.0s and the default setting is 1.0s.
The number of records stored depends on the post-fault recording time and the relay model. The
typical number of records stored in 50Hz and 60Hz power system is shown in Table 3.4.3.1.
Note: If the recording time setting is changed, the records stored so far are deleted.
