Step 4: Prepare to monitor the operation of the 24 Alarm and Trip functions. Alarm operation can be
verified by monitoring the Major Alarm LED on the protection system's front panel. Operation of
the 24 Trip can be verified by monitoring OUT1.
Step 5: Connect a three-phase, 100 Vac/50-Hz or 120 Vac/60-hertz voltage source (depending on
user's nominal frequency) to Terminals C13 (A-phase), C14 (B-phase), C15 (C-phase), and
C16 (neutral).
Step 6: Apply A-phase voltage at nominal frequency and slowly increase until the Major Alarm LED
lights (V/H PU x Freq x % Alarm = PU) and record the alarm pickup. Slowly decrease the A-
phase voltage until the Major Alarm LED extinguishes and record the dropout.
Step 7: Apply A-phase voltage at nominal frequency and slowly increase until OUT2 closes (V/H Trip x
Freq = PU) and record the pickup. Verify that there is a 24 target on the front-panel display.
Slowly decrease the A-phase voltage until OUT2 opens and record the dropout.
Step 8: (Optional.) Repeat steps 1 through 7 for higher and lower alarm and pickup settings.
Step 9: (Optional.) Repeat steps 1 through 8 for frequencies other than nominal.
