VFD Cooling System Leak Inspection

1.Check for leaks on the refrigerant cooling flange connec- tions to the VFD enclosure.

2.Check for leaks on all tubing internal to the VFD enclo- sure, the tubing flair connection to the VFD module and the TXV valve.

3.Verify that the VFD refrigerant cooling system TXV valve control bulb is securely inserted into the VFD drive module heat sink.

Power Up Verification

1.Inspect control wiring inside the VFD and verify the in- tegrity of the connections between the integrated starter module (ISM) and the VFD module.

2.Close the control power switch in the VFD enclosure.

3.Close the oil pump power switch inside the VFD enclosure.

4.Verify the VFD disconnect switch is in the open position.

5.Close and latch the doors of the VFD enclosure.

6.Apply power to the VFD enclosure. Remove lock outs and close all disconnects.

7.Verify that the CVC/ICVC display powers up and goes to the default screen.

8.Close the VFD disconnect switch.

9.Verify the following actions during the VFD start-up self test:

•The display shows SELF and all LEDs are illumi- nated for 5 to 6 seconds.

•The display reads a 0 after the diagnosis is complete.

•If Err is displayed a fault has been detected. Perform manual reset by establishing a reset through the small hole under the VFD Keypad. If this does not correct the fault contact your Carrier representative.

•If AR with a counting down number is displayed wait for the number to count to 0 and the display should then revert to a 0. If the counter starts over at 30 contact Carrier representative.

Configure VFD Parameters — The VFD controller must have job specific parameters set as defined by the component name- plates and labels. The parameters come preset by the factory, but must be verified prior to start-up by accessing the PRO- GRAM MODE of the VFD controller keypad. For information on how to access the VFD keypad see page 58.

Press the PROGRAM softkey to access the parameter screen to modify or view the following job specific parameters:.
