Configure the VFD — All configurations required by the VFD are supplied by the ICVC through the VFD Gateway. Any configuration changes necessary and possible are made on the ICVC screens. A complete set of configurations is transmit- ted to the VFD each time the controls are powered up.

The following is from the 19XRV PIC III ICVC screen. Pa- rameters in italics are to be entered or confirmed at start-up. Pa- rameters in bold are to be changed only after consulting with Carrier service engineering. See Table 2.

Table 2 — VFD Configurations

*Parameters marked with an * are not downloadable to the VFD but are used in other calculations and algorithms in the ICVC.

NOTES:

1.Parameters in italics are to be entered or confirmed at start-up.

2.Parameters in bold are to be changed only after consultation with ser- vice engineering.

Commissioning the Unit — The commission proce- dure is as follows:

1.If the chiller has been stored outdoors, allow at least 24 hours room temperature stabilization prior to commis- sioning. Ensure any condensation that occurs as a result of the ambient temperature is allowed to evaporate.

2.Enter parameters in the VFD_CONF screen.

3.Install surge suppression devices if required.

4.Review the power wiring and grounding to ensure that it has been properly connected.

5.Visually examine the inside of the drive enclosure to:

a.Look for signs of corrosion or moisture residue.

b.Remove any dirt or debris.

c.Make sure all vents are clear.

6.Apply power to the drive and take thermal measurements of the capacitor bank and power connections. Do this again before start-up.

7.Measure and record the incoming line voltage. Line-to- line voltages should be balanced within 3% as calculated by Rockwell’s procedure below:

Measure voltages phase-to-phase and phase-to-ground.
