It is much more impor- tant to establish a thermal replica, after a complete motor start, that is appropriate for the protection of the motor’s thermal condition. Both jumpers must always be plugged in the same way!

QUANTITY 27 you can determine foor undervoltage protection in a three-phase con- nection that instead of the positive-sequence system V1, the smallest of the phase-to-phase voltages Vphph or 7sjj62 smallest phase-to-ground voltage Vph-n is configured as a measured quantity.

Search Search term s Search. Breaker Failure Protection 50bf Functions 2. The pick-up threshold of the binary inputs must therefore stay substantially below half the rated control DC volt- age.


siemena If, for example, voltage V drops to such degree that the voltages V Both op- erational states are unfavorable as overvoltage may cause for example insulation problems or undervoltage may cause stability problems. Depending on the temperature unit selected in the Power System Data Section 2.

The assignment of voltages to current-carrying phases is shown in the following table. Only then the parameters are set back to “normal”. Don’t show me this message again.

Direct Serial Connection Direct connection of the front operator interface or the rear service interface of the device with the serial inter- face of the operator PC. Page 38 Functions 2.

If no measuring voltage is connected to this input, this subsection is irrelevant. Failure to observe these precautions can result in death, personal injury, or serious material damage. Other internal commands such as manual entry or abort are not checked, i. Control Center Solutions go. This means that the line can be connected again.
