This equipment is to be installed by qualified personnel, complying to current standards.
Before any maintenance operation on the device, remove all the voltages from measuring and supply inputs and short-circuit the CT input terminals.
The manufacturer cannot be held responsible for electrical safety in case of improper use of the equipment.
A circuit breaker must be included in the electrical installation of the building.
Clean the device with a soft dry cloth; do not use abrasives, liquid detergents or solvents.
The PMVF 80 equipment has been designed as an Interface Protection (IP) in accordance with VDE-AR-N 4105 and VDE V 0126-1-1 application guide.
It can be applied to all LV generation systems (photovoltaic, wind) where it is used to control the interface switch between generation system and public grid.
In the event of Interface Switch (IS) failure, it can also control a backup device to disconnect the generation system in any case.
The equipment features 4 digital inputs permitting the connection of the system to the signals provided by the network operator.
The PMVF 80 equipment is supplied already programmed and assembled. With the factory settings, it is ready for operation.
Changes to the settings are password protected, preventing tampering by unauthorised personnel.
Modular construction for DIN rail, 6 units.
LCD graphic 128x80 pixel, backlit, 4 grey levels. Display and setting buttons.
Voltage measuring inputs three-phase + neutral. Possibility of operation in the following line configurations.
2 switching relay outputs to control: OUT1: IS (Interface Switch) coil control; OUT2: backup device control.
4 contact digital inputs for: INP1: IS feedback input; INP2: R.O.C.O.F and Vector Shift monitoring function inhibition.
Optional additional measurements, via connection of external CTs: Currents; Powers; Energies supplied.
The voltage and frequency trip thresholds for which the equipment is set up according to the factory defaults are listed below.
PMVF 80 can be set to P≤50kW or P>50kW cases by specific commands available in the command menu.
Loss of mains thresholds (islanding detection): R.O.C.O.F (rate of change of frequency) Vector shift.
