BE1-CDS220 relays have three of each phase, neutral, and negative-sequence instantaneous
overcurrent elements with settable time delay. The screens for the instantaneous elements are almost
identical to the 51 screen. The settable time delay is the primary difference. See Figure 14-18. To change
the time delay, pull down the Time menu, select your preferred unit of measure, and then change the time
for the appropriate phase, neutral, or negative-sequence element.
