Figure 5.6.2. Subsection dedicated to the setting of the common trigger.

Click on the Add button to set-up a new condition. Click in the Edit combination section the select

box for the single MRs. In the column Name you may enter a mnemonic for this condition (e.g. MR

in cellar). In the column Selected the logical combination of this condition is shown. The logical

combination of all conditions is shown in the section Logic function.

A simple example is here presented. You have to install 2 instruments to monitor the vibration in a

5-floors building. 1 MR is in the cellar, one MR in the middle of the room on the 5th floor. As there is

a lot of activity in the room on the 5th floor, you don't want to use a trigger (disable the trigger) on

this instrument, but you would like to have a recording on this instrument if the vibration in the cellar

exceeds the threshold level. For this simple example, the MR in the cellar alone can issue a

common trigger, so you have one single condition and you check only the MR in the cellar.

If a file is recorded due to a common trigger condition, this is shown in the Recording List with the

entry Common in the column Reason. If at the same time in the corresponding MR also the local

criteria for triggering were met, there will be 2 recordings of the same time history, but with different

starting time and duration – the file recorded due to the common trigger overlaps the file due to the

local trigger. The files due to common trigger have the same start time and the same duration in all

the MRs in the network.

To get only files due to a common trigger from the Recording list, you will have to apply a filter for

the Reason.
