Step 3: Using Table 13-7 as a guide, transmit the low range setting commands (minimum pickup

setting) for your sensing input type.

Step 4: Slowly increase the A-phase current until OUT1 closes. Verify that pickup occurs within the

specified accuracy listed in Table 13-8. Slowly decrease the applied current until OUT1 opens.
Dropout should occur at 93 to 97 percent of pickup.

Step 5: Repeat Step 4 while monitoring OUT2 (50TN enabled for 3Io). Verify 50TA and 50TN targets on

the HMI.

Step 6: Repeat Steps 4 and 5 for the middle and high range pickup settings for your sensing input type.

Step 7: (Optional.) Repeat Steps 3 through 6 for phase B (Terminals D3 and D4) and phase C

(Terminals D5 and D6).

Step 8: (Optional.) Repeat Steps 1 through 7 for the 150T elements. Overwrite the 50T commands

entered in Step 2 with the commands of Table 13-9.

Purpose

A=

Gains write access.

SL-150T=1,0; SL-150TN=1,0

Enables 150TP and 150TN, and 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,
150TPPU+150TNPU,0

Enable 150TPT or 150TNT to log and trigger fault recording.

EXIT;Y

Exit and save settings.

Step 9: (Optional.) Repeat Steps 1 through 8 for the 50T and 150T elements in Setting Group 1. Before

testing settings in other setting groups, a setting group must be selected using the CS/CO-
GROUP commands. To activate Setting Group 1, CS-GROUP=1 would be entered to select
Setting Group 1 and CO-GROUP=1 would be entered to make Setting Group 1 active.
