    2.1 General safety instructions Part of the device documentation in addition to this manual is the enclosed "Safety in- structions for Bender products". Read the operating manual before starting to install, connect and commission the device. After successful commissioning, keep the man- ual within easy reach for future reference.

  • Page 12: Device-Specific Instructions

    2.4 Intended use The VMD460-NA voltage and frequency monitoring relay is used for network and sys- tem protection (NS protection) of CHP plants, wind power stations, hydroelectric power stations and photovoltaic systems feeding power into the network. If inadmissible volt- age and frequency values occur on the supply side, the VMD460-NA disconnects the generating plant from the public network by means of the interface switch.

  • Page 13: Functional Description

    Monitoring of different system types: 1AC, 3AC, 3NAC The VMD460-NA is able to monitor different system types (1AC, 3AC, 3NAC). The system type is defined via the "Coupling" parameter. In addition, the nominal system voltage is set via the "U "...

  • Page 14: Disconnection

    As soon as at least one of the activated protective or monitoring functions has tripped, the VMD460-NA issues a disconnection command via contacts K1 and K2 to the con- nected interface switches. First K1 and then K2 are tripped with a delay of 50 ms.

  • Page 18: Unbalance Detection

    Functional description The vector shift detection detects phase displacements (vector shift) in the network voltage. if the ° measured value exceeds the response value, the protective function is tripped.

    A remote trip signal can be connected to the RTG1 and RTG contacts for remote discon- nection, e.g. via a ripple-control receiver. If a remote trip signal is applied to the RTG1 and RTG contacts, the VMD460-NA trips re- lay K1 (and if necessary K2) after ≤ 50 ms and the alarm LEDs light up.

    • Devices damaged in transit must not be used. If a device has sustained damage, please contact Bender. Details of who to contact are indicated on the delivery document. • When storing the devices in an environment where the temperature is wintry and cold: Leave the devices to stand for 3 to 4 hours at room temperature before connecting the power supply.

  • Page 24: Installation Instructions

    The length of the connecting cable of the device connections DG1/2, D1, D2, DG3/4, D3, D4, RTG and RT1 is to be limited to 3 m. In order to ensure the proper functioning of the VMD460-NA after a pow- er failure, an external UPS is to be used.
