Protective elements blocked by 60FL should be set so that trip times are 60 milliseconds or greater to
assure proper coordination of blocking.

Block Logic Input

The Block input provides logic-supervision control of the element. In a typical application, the power factor
element will be blocked during motor start-up and until reaching synchronous speed.

When true, the Block input disables the element by forcing the Trip and Pickup outputs to logic 0 and
resetting the element timer. Connect the element Block input to the desired logic in BESTlogicPlus. When
the element is initially selected from the Elements view, the default condition of the Block input is a logic
0.

Logic Connections

Power factor element logic connections are made on the BESTlogicPlus screen in BESTCOMSPlus. The
power factor element logic block is illustrated in Figure 62. Logic inputs and outputs are summarized in
Table 33.
