It is possible to control and monitor the recording status of the disturbance recorder

by writing to and reading SPA parameters M1, M2 and V246. Reading SPA

parameter V246 returns either the value 0 or 1, indicating whether the recorder has

not been triggered or triggered and ready to be uploaded. Event code E31 is

generated the moment the disturbance recorder is triggered. If the recorder is ready

to be uploaded, this is also indicated by an asterisk shown in the lower right-hand

corner of the LCD when it is in the idle mode. Indication can also be routed to

programmable LEDs.

Writing the value 1 to SPA parameter M2 clears the recorder memory and enables

the triggering of the recorder. Recorder data can be cleared by performing a master

reset, that is, clearing indications and memorized values and unlatching output

contacts.

Writing the value 2 to SPA parameter V246 restarts the unloading process by setting

the time stamp and the first data ready to be read.

5.1.11.4. Triggering

The user can select one or several internal or external digital input signals to trigger

the disturbance recorder, either on the rising or falling edge of the signal(s).

Triggering on the rising edge means that the post-triggering recording sequence

starts when the signal is activated. Correspondingly, triggering on the falling edge

means that the post-triggering recording sequence starts when the active signal is

reset.
