Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs.

Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

Notes:

• Unit must be powered ON to complete adding VFD parameters.
• Remove Emergency Stop factory jumper on LTB1-5, 6 or field installed wire at LTB1-6 to disable unit during LCP rogramming.
• Verify 24VAC is no longer present at LTB1-6 before starting programming.

Programming by hand with the LCP instructions:

1. When programming the parameters, go in order from top of the table above to bottom. Before beginning this step, press the “Off/Reset” button to stop the drive so that it will not run.
2. On the LCP, press menu twice to enter the main menu and enable parameter selection. Then press up or down to select the correct group (from groups 0 to 14).
3. Press OK to enter that group, then up or down to select the specific parameter in that group. Example, 14-01 is group 14 parameter 01.
4. Press OK to edit the parameter and it will flash, then press up or down to change the value. Press OK when done and it will stop flashing and is saved automatically.
5. Program the value in column “FC”. If it’s a numerical value, it may be necessary to hold the up or down arrow to get to the correct value faster. If it’s an enumerated value, example “[4]”, choose that number from the list.
6. Parameters 13-10 to 13-52 have sub-groups. First select group 13, then select from group 0 to 2, then adjust the value setting. See column “Notes” for which sub-group to enter.
7. Push the “Auto/On” button to ready the drive to be started and controlled.

How to copy VFD parameters to the keypad (Danfoss FC51):
Note: This is highly recommended if more than one VFD is installed.

1. Press the menu button twice. The keypad should look as follows:

2. Press one of the two arrow buttons until the number 0-50 appears.

3. Press OK and the number 0 will flash, then press upper arrow until the number 1 appears, then press OK.

4. When the operation completes, the word done will be shown briefly on the keypad. All the VFD parameters have now been saved to the internal memory of the keypad. To return to the VFD status on the keypad, press back twice.

5. You can now take the LCP to other VFDs that require programming. Go back to the parameter 0-50 and select option [2] all from LCP. This will copy parameters from the LCP to VFD.
