WARNING

Hazardous Voltage! w/Capacitors!

Disconnect all electric power, including remote discon- nects before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other en- ergy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for al- lowable waiting periods for discharge of capacitors. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and dis- charge capacitors before servicing could result in death or serious injury.

Note: For additional information regarding the safe dis- charge of capacitors, see PROD-SVB06A-EN

VFD Programming Parameters

Units shipped with an optional variable frequency drive (VFD) are preset and run tested at the factory. If a problem with a VFD occurs, ensure that the programmed param- eters listed in Table 5-8 have been set before replacing the drive.

Note: Check to make sure that parameter 104 is set to 60 Hz. To check parameter 104 press the Extended Menu button, press the Left Arrow button until menu Load & Motor is shown, press the up arrow until parameter 104 is displayed. Parameter 104 can then be modified by pressing the Change Data button and then the Up Arrow button. When the desired selection has been made press the OK button.

Should replacing the a VFD become necessary, the re- placement is not configured with all of Trane's operating parameters. The VFD must be programmed before at- tempting to operate the unit.

To verify and/or program a VFD, use the following steps:

1.At the unit, turn the 115 volt control circuit switch 1S70 to the "Off" position.

2.Turn the 24 volt control circuit switch to the "Off' position.

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote discon- nects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvert- ently energized. Failure to disconnect power before ser- vicing could result in death or serious injury.

HIGH VOLTAGE IS PRESENT AT TERMINAL BLOCK 1TB1 OR UNIT DISCONNECT SWITCH 1S14.

3.To modify parameters:

(a)Press the Extended Menu button
