Basler Electric BE1-11g - Manual (Page 251)

9424200994 Rev N 239
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 171. The logic output is summarized in Table 93.

Name Logic Function Purpose
Fuse Loss Output True when the 60FL logic is true
Operational Settings
Fuse loss element operational settings are configured on the Fuse Loss (60FL) settings screen (Figure
172) in BESTCOMSPlus. Settings are summarized in Table 94.

Setting Purpose
Block Voltage Control (51/27) 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.
Block Phase/V1 Voltage
Elements All functions that use phase voltage (P) and positive-sequence
voltage (V1) measurements are blocked when the 60FL logic is
true. (25, 25A, 27, 59, and 78V)
Block 3V0 Voltage Elements All functions that use the three-phase residual voltage (3V0)
measurement are blocked when the 60FL logic is true. (27X, 59X -
3V0 mode)
