Programming Example
Changing default logic is sometimes required to match the protection requirements of the system.
Additionally, elements must be enabled and operating settings set. This example demonstrates how to
configure typical nominal settings and program the 50-4 instantaneous overcurrent element. System
nominal quantities are set to 69.3 volts and 3.6 amps. Motor parameters are set to 4.5 Full Load Amps
and 1.15 Service Factor. The 50-4 element is set for a 5.62 amp pickup and a 30 second time delay.
Additionally, the element pickup output is logically wired to output 4 and a user alarm.
Step 1: Start BESTCOMSPlus and select New Connection, BE1-11 from the Communication pull-down
menu to connect to the BE1-11m. See Figure 2-5.
Step 2: The BE1-11 Connection screen appears. See Figure 2-6. Select USB Connection and click
Connect.
Step 3: Select Download Settings and Logic from Device from the Communication pull-down menu. This
