Basler Electric BE1-700 - Manual (Page 312)

In addition, the pickup settings made in Step 3 (Table 13-7) must be changed to specify the
setting group being tested. To test settings in Group 1, replace the 0 in the S0-x50 commands
with a 1 (S1-x50).
50TP/150TP and TN (Calculated 3Io) Time Delay Verification
Step 1: Connect a current source to Terminals D1 and D2 (A-phase). Refer to Figure 12-3 for terminal
locations.
Step 2: Prepare the 50T/150T elements for testing by transmitting the commands in Table 13-10 to the
relay.
Table 13-10. 50TP and 50TN Time Delay Test Commands
Command Purpose
A= Gains write access.
SL-N=NONE Zero out custom logic settings. Overwrite with LOGIC=NONE settings.
Y Confirm overwrite.
SL-N=TD50 Sets TD50 as custom logic name.
SL-50TP=1,0; SL-50TN=1,0 Enables 50TP and 50TN (3Io), and disables blocking.
SL-VO1=50TPT Enables OUT1 to close for 50TP trip.
SL-VO2=50TNT Enables OUT2 to close for 50TN trip.
SG-CT=1 Sets P, N CT ratio at 1:1
SG-TRIG=50TPT+50TNT,
50TPPU+50TNPU,0
Enable 50TPT or 50TNT to log and trigger fault recording.
EXIT;Y Exit and save settings.
Step 3: Using Table 13-11, transmit the first column of setting commands.
Table 13-11. 50T and 150T Time Delay Settings
Pickup and Time Delay Settings
Purpose
2 Second TD 5 Second TD 10 Second TD
S0-50TP=0.5,2S S0-50TP=0.5,5S S0-50TP=0.5,10S Sets 50TP TD.
S0-50TN=0.5,2S S0-50TN=0.5,5S S0-50TN=0.5,10S Sets 50TN TD.
Step 4: Step the applied A-phase current to .55 amps (for 1 amp CT circuit divide by 5). Measure the
time delay and verify the accuracy of the 50TP time delay setting, OUT1, and 50TN, OUT2.
Timing accuracy is
±5 percent or ±3 cycles of the time delay setting.
Step 5: Repeat Steps 2 and 3 for the middle and higher time delay settings in Table 13-11.
Step 6: (Optional.) Repeat Steps 3 through 5 for phase B (Terminals D3 and D4), phase C (Terminals
D5 and D6).
Step 7: (Optional.) Repeat Steps 1 through 6 for the 150T elements. Overwrite the 50T commands
entered in Step 2 with the commands of Table 13-12.
Table 13-12. 150TP and 150TN Time Delay Test Commands
Command Purpose
A= Gains write access.
SL-150TP=1,0; SL-150TN=1,0 Enables 150TP and 150TN, disables blocking.
SL-VO1=150TPT Enables OUT1 to close for 150TP trip.
SL-VO2=150TNT Enables OUT2 to close for 150TN trip.
SG-TRIGGER=150TPT+150TNT, Enable 150TPT or 150TNT to log and trigger fault recording.
