Basler Electric BE1-700 - Manual (Page 366)

A dialog box (BESTlogic Function Element) opens showing the status of the element logic and the logic
scheme name. If you have a custom logic scheme active, you may change the status of the element logic
by pulling down the menu and selecting from the available choices. The 151 element is adjusted in a
similar fashion to the 51 element.
50T and 150T (Instantaneous Overcurrent with Settable Time Delay)
The BE1-700 relay has six instantaneous elements (three with the 50T element and three with the 150T
element). See Figure 14-13 for the 50T element. The tabs for the instantaneous elements are almost
identical to the 51/151 tabs. The settable time delay is the primary difference. To change the time delay,
click the Time menu Down arrow and select your preferred unit of measure (milliseconds, minutes, or
cycles). Then change the time for the appropriate phase, neutral, or negative-sequence element. The
150T element is set in a fashion similar to the 50T element.
