Logic Connections; Operational Settings - Basler BE1-11g Instruction Manual

9424200994 Rev U
Programmable Alarm
The BE1-11g indicates an alarm condition when the 60FL element detects a fuse loss or loss of potential.
The alarm appears on the front-panel display, web page interface, and on the Alarms metering screen in
BESTCOMSPlus. Refer to the Alarms chapter for information on how to program alarms.

Logic Connections

Fuse loss logic connections are made on the BESTlogicPlus screen in BESTCOMSPlus. The fuse loss
element logic block is illustrated in Figure 179. The logic output is summarized in Table 98.

Output True when the 60FL logic is true

Table 99. Operational Settings
When enabled and the 60FL logic is true (voltage sensing is lost),
the current tripping level is controlled by the 51 function and the
27R function is inhibited. When enabled and the 60FL logic is
false, the current tripping level is controlled by the 51/27R
function.
All functions that use phase voltage (P) and positive-sequence
voltage (V1) measurements are blocked when the 60FL logic is
true. (24, 25, 25A, 27, 59, and 78V)
All functions that use the three-phase residual voltage (3V0)
measurement are blocked when the 60FL logic is true. (27X, 59X -
3V0 mode)
