The interval channels (VDV-V, VDV-L, VDV-T) are the VDV values
accumulated over each interval. The interval channels (VDV-V accu,
VDV-L accu, VDV-T accu) are the VDV values accumulated over each
day and night. Day is defined as the period 07:00 – 23:00, and night is
defined as the period 23:00 – 07:00. The VDV accu values are seen as the
main interval values and are therefore displayed in the GUI of the C22.
In summary we have nine interval values:
•
V, L, T: Band pass filtered acceleration.
•
VDV-V, VDV-L, VDV-T: VDV over each interval
•
VDV-V accu, VDV-L accu, VDV-T accu: VDV over each day
(07:00 – 23:00) and each night (23:00 – 07:00)
Trigger an SMS and/or e-mail
VDV accu is also the base for the possibility to trigger an event, which
can be used to generate an SMS or e-mail. This is configured in INFRA
Net.
Note!
Recordings are disabled in the VDV-standards 70A and 70B (but
enabled for all other standards, including 71A and 71B).
