DIRIS DIGIWARE - 546420C - SOCOMEC
VirtualMonitor can only be used if the DIRIS Digiware U module is connected upstream of the protective device, and
the DIRIS Digiware S module downstream. This is illustrated in the architecture below:
L1
L2
L3
Thanks to its voltage detection capability, the DIRIS Digiware S module can detect the position of the protective
device. An example corresponding to the above illustration is given in the table below:
Voltage measured on U module (*)
Yes, 230V L-N
Voltage detected on S modules
Yes
No, 0V
Yes

(*) Earth must be connected on the DIRIS Digiware U module
When a Circuit breaker is used, the technology also enables to detect and count trips. A trip is detected if the 2
following conditions are met:
• the DIRIS Digiware S module records an opening of the protective device
• the DIRIS Digiware S module records a current surge ≥ 120% In(**)
(**) It is important to configure the nominal current correctly in the “Loads” configuration menu for the Virtual monitor
function to work correctly.
Several protection counters are also accessible thanks to the VirtualMonitor technology:
Protection counter type
Description
Total operation counter
Number of times the protective device was opened
Low-load operation counter
Number of times the protective device was opened
when load current was ≤ 5% Inom
On-load operation counter
Number of times the protective device was opened
when load current was [5% Inom – 100% Inom]
Overload operation counter
Number of times the protective device was opened
when load current was ≥ 100% Inom
Trip Counter
Number of times the protective device tripped (only available if the protective device is
a breaker).
DIRIS Digiware S is able to detect several successive openings of a protective device if the interval
between 2 openings is greater than or equal to 200ms.
