Customizable measurements overview
The RVT allows you to sort your preferred data in such a way that they are viewed first on the graphics display.
Day – night target cos ϕ
The RVT allows the programming of two different target cos ϕ values.
Locking switch
Unauthorised use may be blocked by a switch at the back of the RVT.
Alarm logging
The last five alarm messages are recorded and may be consulted at any time.
Event logging
For selected measured parameters and according to the threshold set, the RVT records:
- the maximum value logged between two resets.
- the total duration during which the measured value has exceeded the threshold.
Example: event logging of Total Harmonic Distortion on Voltage

Optional accessories
Modbus adapter
All RVT controllers are Modbus communication enabled. The Modbus adapter is
an optional item which allows communication with a monitoring system.
All RVT parameters are available (including harmonic spectrum and tables)
through an RS485 Modbus adapter.
All RVT parameters are accessible and locking parameters allows to limit their
access through the Modbus communication only.
External probes for temperature measurements
Two temperature probes may be connected to the RVT.
The RVT will close the fan relay if a temperature threshold is exceeded.
Information on temperature may be recorded with the event logging function.
Printer connection
The RVT can be connected to a printer through the isolated RS-232 serial port.
ABB printer cable is needed.
IP54
The RVT front plate offers an IP43 protection degree in standard version.
The gasket accessory enhances the standard RVT protection degree to IP54.
