annunciate the condition and to initiate corrective action. If a target is enabled for the element, the
BE1-11g will record a target when the Trip output becomes true. See the
Fault Reporting chapter for more
information about target reporting.
Voting
The Voting parameter defines the number of RTDs in the group that must exceed the pickup setting to
cause a trip. For example, if the 49RTD-1 Voting setting is three, then at least 3 RTDs in the selected
group must exceed the pickup setting to cause a trip.
Element Blocking
The Block input provides logic-supervision control of the element. 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
Remote RTD input element logic connections are made on the BESTlogicPlus screen in
BESTCOMSPlus. The remote RTD input element logic block is illustrated in Figure 91. Logic inputs and
outputs are summarized in Table 54.
