Table 42-2. Logic Output

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

42-3) in BESTCOMSPlus. Settings are summarized in Table 42-3.

Table 42-3. Operational Settings

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. (27 and 59)

Block 3V0 Voltage Elements

All functions that use the 3-phase residual voltage (3V0)

measurement are blocked when the 60FL logic is true. (59X - 3V0

mode)

Block V2 Voltage Elements

All functions that use the negative-sequence voltage (V2)

measurement are blocked when the 60FL logic is true. (59X - V2

mode)

Block Power/Power Factor

Elements

All functions that use the power measurements are blocked when

the 60FL logic is true. (32 and 55)

Ignore Breaker Status

When enabled, breaker status is ignored.
