The new NewCode motor protection and control relay from NewElec is fully Profibus accredited and retains the user-friendly features that are synonymous with the company’s products. Customers will benefit from the Vectorial stall protection that allows the disengagement of the motor if a stall condition occurs on start-up, should there be no improvement in the power factor after three seconds. The relay provides pre-motor start insulation failure protection and power measurements that distinguish between real and apparent power consumption.
NewCode’s load loss/dry-run protection allows the user to decide if the load loss measurement will be done on current or power factor measurements and accommodates the required priming time. Earth leakage protection is provided with user-selectable tripping curves and sensitivity levels and includes harmonics filtering.
The onboard data base stores events and fault records and the continuous coloured flashing LED provides a visual indication of the communications address. Control panel mounted display LEDs indicate the I/O status.
NewCode’s free innovative front-end software adds substantial value as the training simulator permits easy assimilation of relay functions though an emulator. It has a recording capability for visual interpretation of motor running currents, voltages and thermal condition. A sophisticated calculator answers many ‘what if’ questions and assists with parameterisation of the relay.
Various add-on modules are available, including additional I/O, 4 to 20 mA analogue ‘in’ or ‘out’ and RTD real-time temperature sensing.
