Table 13-53. BF Pickup Test Commands
Command Purpose
A= Gain write access
SL-N=NONE Zero out custom logic settings. Overwrite with
logic = none settings.
Y Confirm overwrite
SL-N=BF Sets BF as custom logic name
SL-BF=1,IN4,/IN3 Enables BF CT input 1, IN4 initiate, /IN3 block
SL-VO1=BFT Enables OUT1 to close for BF trip
SL-VO2=BFPU Enables OUT2 to close for BF pickup
SG-CT=1,WYE,NA,0 Input 1 ctr=1, ct=wye, xfmr=na, no grd source
SG-TRIGGER=BFT,BFPU,0 Enable BFT to log and trigger fault recording
SP-BF=50m Set BF time delay at minimum
EXIT Exit
Y Save settings
Step 2. Apply wetting voltage to relay inputs IN3 and IN4. This applies the BF initiate, and removes the
BF block...
The BF current detector dropout setting is a fixed value that is determined by the relay current
sensing type. Table 13-54 lists the pickup setting for each current sensing type.
Table 13-54. BF Current Detector Dropout Settings
Sensing Type Dropout Setting
A or B (1 ampere nominal systems)
0.1 A
D, E, or F (5 ampere nominal systems)
0.5 A
Step 3. Connect a current source to terminals B1 and B2 (A-phase input). Slowly decrease the current
applied until OUT2 (and subsequently OUT1) opens. Compare the applied current to the
current values listed in Table 13-55. Verify that dropout occurred between the lower and upper
limits for your relay.
Table 13-55. BF Dropout Limits
Sensing Type Lower Dropout Limit Upper Dropout Limit
A or B (1 ampere nominal systems)
0.09 A 0.11 A
D, E, or F (5 ampere nominal systems)
0.45 A 0.55 A
Step 4. Transmit the commands in Table 13-56 to set the BF time delay.
Table 13-56. BF Time Delay Commands
Command Purpose
A= Gain write access
SP-BF=100m Sets BF time delay at 100 milliseconds
EXIT Exit
Y Save settings
Step 5. Verify the BF time delay by applying nominal current for the duration given in the following
steps.
1. Apply nominal current to phase A for 4 cycles (67 ms at 60 Hz). No trip should occur.
2. Apply nominal current to phase A for 5 cycles. (83 ms at 60 Hz). No trip should occur.
