Table 13-40. 27P and 59P Pickup 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=27_59 Sets 27_59 as custom logic name.
SG-VTP=1,4W,PN,PN Set VT phase voltage parameters.
SA-MAJ=0 Disables Major Alarm.
SL-27P=1,0 Enables 27P, disables blocking.
SL-59P=1,0 Enables 59P, disables blocking.
SL-VO1=27PT+59PT Enables OUT1 to close for 27P or 59P trip.
SG-TRIG=27PT+59PT,
27PPU+59PPU,0
Enables 27P and 59P to log and trigger fault record.
SG-TARG=27/127/59/159 Enables 27, 127, 59, and 159 targets.
EXIT;Y Exit and save settings.
Step 2: Using Table 13-41 as a guide, transmit the first row of setting commands (highest 27P PU,
lowest 59P PU) to the relay.

Phase Pickup Settings
Purpose
Undervoltage Overvoltage
S0-27P=96,50ms S0-59P=132,50ms Sets 27P PU at 96 V, 59P at 132 V, TD at min
S0-27P=84,50ms S0-59P=144,50ms Sets 27P PU at 84 V, 59P at 144 V, TD at min
S0-27P=72,50ms S0-59P=156,50ms Sets 27P PU at 72 V, 59P at 156 V, TD at min
Step 3: Prepare to monitor the 27P and 59P function operation. Operation can be verified by monitoring
OUT1.
Step 4: Connect and apply a 120 Vac, three-phase voltage source to Terminals C13 (A-phase), C14 (B-
phase), C15 (C-phase), and C16 (Neutral). Refer to Figure 12-4 for terminal locations.
Step 5: Slowly decrease the A-phase voltage until OUT1 closes. Pickup should occur within
±2 percent
or 1 volt of the 27P pickup setting. Slowly increase the A-phase voltage until OUT1 opens.
Dropout should occur between 102 and 103 percent of the actual pickup value. Verify the 27A
target and the HMI. Reset the target.
Step 6: Continue increasing the A-phase voltage until OUT1 closes. Pickup should occur within
±2
percent or 1 volt of the 59P pickup setting. Slowly reduce the A-phase voltage until OUT1
opens. Dropout should occur between 97 and 98 percent of the actual pickup value. Verify 59A
target on the HMI.
Step 7: Verify the pickup and dropout accuracy of the middle and upper pickup settings listed in Table
13-41.
Step 8: (Optional.) Repeat Steps 2 through 7 for the B-phase and C-phase voltage inputs.
Step 9: (Optional.) Repeat Steps 2 through 8 for Setting Group 1.

Step 10: Using Table 13-42 as a guide, transmit the setting commands to the relay.
