VirtualMonitor can only be used if the DIRIS Digiware U module is connected upstream of the protective device, and the
current sensor downstream. This is illustrated in the architectures below:
Architecture 1: with DIRIS Digiware I module and iTR sensors
L1
L2
L3
Thanks to its voltage detection capability, the iTR sensors connected to DIRIS Digiware I modules can monitor the position
of the protective device. An example corresponding to the above illustration is given in the table below:
MCB 1
MCB 2
Voltage on U module ?
Yes, 230 V L-N measured for instance
Voltage detected by iTR ?
Yes
No
Position of MCB
Closed
Open
Architecture 2: with DIRIS Digiware S
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
