VLOG-10
4�2�1�- LOGS
These are the mains voltage measurements in RMS value.
They occur synchronously, i.e. they are stored in the memory at certain intervals that are estab-
lished in the device's configuration.
4�2�2�- EVENTS
Events are occurrences or incidents detected on the mains.
They are generated asynchronously and are stored in the memory at the precise moment when
they are detected.
VLOG-10 can analyse and record the following events:
Table 4: Events recorded�
Event Description
Device start-up Event logged in the memory when the device is starting up.
Voltage gap
Event logged in the memory when the voltage level is below the thresh-
old defined in the device's pre-configuration and above 85 V~.
Overvoltage
Event logged in the memory when the voltage level is above the thresh-
old defined in the device's pre-configuration.
Voltage interrupt Event logged in the memory when the voltage level is below 85 V~ .
Frequency
variation
An event that occurs when a fluctuation in the mains's input frequency
is detected (
50
or
60 Hz
), through the configuration of a threshold that is
defined in the device's pre-configuration.
Memory deletion
Event logged in the memory, indicating the time and date on which the
stored data was deleted (events and logs).
4.3.- RESET BUTTON
The VLOG-10 device has a LOG RESET button for resetting the log memory used to store logs
and events.

Figure 5:Reset button
The device must be connected to the PC in order to delete the memory.
If it is connected and the device is switched on and you hold down the button for 2 to 5 seconds,
all data stored to date will be deleted.
