Furthermore, this type of 7sjj62 is dealt with in the func- tional descriptions. Page Page Page Page – A. The 7SJ64 relay comprises 4 syn- chronization function groups SYNC function group 1 to 4 which each contain all setting parameters for one synchronizer. If no measuring voltage is connected to this input, this subsection is irrelevant. Measurement Voltage Failure Detection Functions 2.

Grounding Grounding is the total of all means and measured used for grounding. Page 45 Functions 2. Numerical siemems, motor and overload relay pages. Here the delta address must be set to VT Connect. Settings indicated above are to be used prevaling 3 cold and 2 warm startup attempts have resulted in the restart limit reaching Synchronization Function Functions 2.

Average Measurements Functions 2. A startup brings the machine from load operation into a temperature range far above the thermal restarting limit and the machine is stopped.

Service Interface Checking: On tripping without fault current, e. A—N Threshold values for voltage protection are set as follows: Page 69 Functions 2.

They are summarized in the following table. Page 89 Functions 2. Additionally, user-defined interlocking conditions semens be programmed separately for each command. By cleaning up projects, you can release these memory areas. When the delay time has elapsed and the threshold is still violated, the pickup of the phase e.
