Basler Electric BE1-700 - Manual (Page 328)

Step 2: Using Table 13-49 as a guide, transmit the first row of setting commands (highest 27X PU,
lowest 59XPU/159XPU) to the relay.
Table 13-49. 27X and 59X/159X Pickup Settings
Pickup and Time Delay Settings
Purpose
Undervoltage Overvoltage
S0-27X=70,50ms,0 S0-59X/159X=90,50ms
Sets 27X PU at 70 V, 59X/159X at 90 V, TD
at min, UV Inhibit disabled.
S0-27X=60,50ms,0 S0-59X/159X=100,50ms
Sets 27X PU at 60 V, 59X/159X at 100 V,
TD at min, UV Inhibit disabled.
S0-27X=50,50ms,0 S0-59X159X=110,50ms
Sets 27X PU at 50 V, 59X/159X at 110 V,
TD at min, UV Inhibit disabled.
Step 3: Prepare to monitor the 27X and 59X/159X function operation. Operation can be verified by
monitoring OUT1.
Step 4: Connect and apply a single-phase, 80 Vac voltage source to VX Input, Terminals C17 (polarity)
and C18 (non-polarity). Refer to Figure 12-4 for terminal locations.
Step 5: Slowly decrease the voltage until OUT1 closes. Pickup should occur within
±2 percent or 1 volt
of the pickup setting. Slowly increase the voltage until OUT1 opens. Dropout should occur
between 102% and 103% of the actual pickup value. Verify the 27 bus target on the HMI and
reset.
Step 6: Continue to increase the voltage until OUT1 closes. Pickup should occur within
±2 percent or 1
volt of the pickup setting. Slowly reduce the voltage until OUT1 opens. Dropout should occur
between 97% and 98% of the actual pickup value. Verify the 59 Bus target on the HMI.
Step 7: Verify the pickup and dropout accuracy of the middle and upper pickup settings listed in Table
13-49.
Step 8: (Optional.) Repeat Steps 2 through 7 for Setting Group 1.
27X Auxiliary Undervoltage Inhibit Pickup Test (Fundamental VX Test)
Step 1: Using Table 13-50 as a guide, transmit the first row of setting commands to the relay.

Purpose
Undervoltage Overvoltage

at min, UV Inhibit at 50V.
S0-27X=60,50ms,50 S0-59X/159X=100,50ms

TD at min, UV Inhibit at 50V.
Step 2: Prepare to monitor the 27X and 59X/159X function operation. Operation can be verified by
monitoring OUT1.
Step 3: Connect and apply a single-phase, 80 Vac voltage source to VX Input, Terminals C17 (polarity)
and C18 (non-polarity). Refer to Figure 12-4 for terminal locations.
Step 4: Slowly decrease the voltage until OUT1 closes. Pickup should occur within
±2 percent or 1 volt
of the pickup setting. Continue to decrease the voltage until OUT1 opens. UV inhibit pickup
should occur within
±3 percent of 50V. Increase the voltage until OUT1 closes. UV inhibit
dropout should occur at
±5 percent of inhibit pickup.
Step 5: (Optional.) Repeat Steps 1 through 4 for Setting Group 1.
