Step 3: Using Table 13-20, transmit the first row of setting commands for your sensing input type.
Table 13-20. 50TN/150TN Pickup Settings
Sensing
Type
Command Purpose
1 A
S0-50TN=0.1,0,N;S0-150TN=0.1,0,N
Sets 50TN and 150TN pickup at 0.1 A, TD = 0,
non-directional.
S0-50TN=1.0,0,N;S0-150TN=1.0,0,N
Sets 50TN and 150TN pickup at 1.0 A, TD = 0,
non-directional.
S0-50TN=5.0,0,N;S0-150TN=5.0,0,N
Sets 50TN and 150TN pickup at 5.0 A, TD = 0,
non-directional.
5 A
S0-50TN=0.5,0,N;S0-150TN=0.5,0,N
Sets 50TN and 150TN pickup at 0.5 A, TD = 0,
non-directional.
S0-50TN=5.0,0,N;S0-150TN=5.0,0,N
Sets 50TN and 150TN pickup at 5.0 A, TD = 0,
non-directional.
S0-50TN=10.0,0,N;S0-150TN=10.0,0,N
Sets 50TN and 150TN pickup at 10.0 A, TD = 0,
non-directional.
Step 4: Slowly increase the IG current until OUT1 closes. Verify that pickup occurs within the specified
accuracy listed in Table 13-21. 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 (150TN). Verify 50TG and 150TG targets on the HMI.
Verify the pickup accuracy of the middle and upper pickup settings.
Table 13-21. 50TN/150TN Element Accuracy
Sensing Type Pickup Accuracy
B (1 A)
±2% or ±10mA
E or F (5 A)
±2% or ±50mA
Step 6: (Optional.) Repeat Steps 1 through 5 for the 50TN and 150TN elements in Setting Group 1.
50/150TN (Independent Ground Input IG) Time Delay Verification
Step 1: Prepare the 50TN and 150TN elements for testing by transmitting the commands in Table 13-19
to the relay.
Step 2: Using Table 13-22, transmit the first column of setting commands for your sensing input type
(5 A is shown).
Table 13-22. 50TN/150TN Time Delay Settings
Pickup and Time Delay Settings
Purpose
2 Second TD 5 Second TD 10 Second TD
S0-50TN=0.5,2S S0-50TN=0.5,5S S0-50TN=0.5,10S Sets 50TN TD.
S0-150TN=0.5,2S S0-150TN=0.5,5S S0-150TN=0.5,10S Sets 150TN TD.
Step 3: With the current source still connected to Terminals D7 and D8 (IG), step the applied current to
.55 amps (for 1 amp CT circuit divide by 5). Measure the time delay and verify the accuracy of
the 50TN time delay setting, OUT1, and 150TN, OUT2. Timing accuracy is
±5 percent or ±3
cycles of the time delay setting.
Step 4: Repeat Steps 2 and 3 for the middle and higher time delay settings in Table 13-22.
Step 5: (Optional.) Repeat Steps 1 through 4 for Setting Group 1.
