The current input to the control is rated at 0.2 A continuous, 0.4 A for
two hours, and 4.0 A for 1 second.
8. Replace the shorting device across the load current input and remove the ammeter.
9. Reconnect polarity to the unit and remove both jumpers. The Line Drop
Compensator will be activated. Correct CT polarity can be checked by simply
incorporating suffR compensation. The regulator should time out and run so
as to raise the output voltage.
9.4 Performing operational test
1. Set VT Ratio Correction = 0 V; CT/VT phasing = 0° from the appropriate screen in
the software.
2. Return to the Local Voltage screen.
3. Apply 120.0 Vac to Pin 1 (hot) and Pin 3 (neutral) of the adapter panel.
4. Verify local voltage = input voltage ±0.3 V.
5. Apply 100.0 mA in-phase current to Pin 4 (load current-polarity) and Pin 2 (load
current-return).
6. Verify Control Load I =100 mA and Power Factor =1.0 ±0.02 from the appropriate
software screens.
7. Apply 100.0 mA 90° leading current to Pin 5 (circulating current-polarity) and Pin
6 (circulating current-return).
8. Verify Control Circ I = 100.0 mA ±2 mA.
9. Verify the Up, Down and ENT pushbuttons function properly.
10. De-energize the current source.

9.5 Performing in-service test
1. Set the TCC300 Tapchanger Control to display the Bias Voltage screen.
2. Press ENT.
3. Use the Up and Down push buttons to cause RAISE and LOWER outputs.
If either output is blocked, verify that the unit is not at the maximum tap position.
4. Press ENT to return to the Local Voltage screen.
