Carrier WeatherExpert 48LC Series Service And Maintenance Instructions page 48

The arrow icon indicates the drive and motor rotation status. A ro-
tating arrow (clockwise or counterclockwise) indicates that the
drive is running and at set point and the shaft direction is forward
or reverse. A rotating blinking arrow indicates that the drive is
running but not at setpoint. A stationary arrow indicates that the
drive is stopped. For the units covered in this manual, the correct
display rotation is clockwise.
The upper-right corner shows the frequency setpoint that the drive
will maintain.
Using parameter group 34, the middle of the LCD display can be
configured to display 3 parameter values. The default display
shows parameters 0103 (OUTPUT FREQ) in percent speed, 0104
(CURRENT) in amperes, and 0120 (Al1) in voltage DC.
The bottom corners of the LCD display show the functions cur-
rently assigned to the two soft keys. The lower middle screen dis-
plays the current time (if configured to show the time).
The first time the drive is powered up, it is in the OFF mode. To
switch to local hand-held control and control the drive using the
control panel, press and hold the HAND button. Pressing the
HAND button switches the drive to hand control while keeping
the drive running. Press the AUTO button to switch to remote in-
put control. To start the drive press the HAND or AUTO buttons,
to stop the drive press the OFF button.

tion in the remote control mode.

DRIVE PARAMETER BACKUP MODE
The drive parameter back-up mode is used to export the
parameters from one drive to another. The parameters can be
uploaded from a VFD to the removable control panel. The control
panel can then be transferred to another drive and the parameters
are downloaded into memory.
Depending on the motor and application, there are two options
available. The first option is to download all parameters. This
copies both application and motor parameters to the drive from the
control panel. This is recommended when using the same
application for drives of the same size. This can also be used to
create a backup of the parameters group for the drive.
The second option downloads only the application parameters to
the drive. This is recommended when using the same application
for drives of different sizes.
Upload All Parameters
To upload and store parameters in the control panel from the VFD,
perform the following procedure:
1. Select MENU (SOFT KEY 2). The main menu will be
displayed.
2. Use the UP or DOWN keys to highlight PAR BACKUP on
the display screen and press ENTER (SOFT KEY 2).
3. Use the UP or DOWN keys to highlight UPLOAD TO
PANEL and press SEL (SOFT KEY 2).
4. The text "Copying Parameters" will be displayed with a prog-
ress indicator. To stop the process, select ABORT (SOFT
KEY 1).
5. When the upload is complete, the text "Parameter upload suc-
cessful" will be displayed.
6. The display will then return to the PAR BACKUP menu.
Select EXIT (SOFT KEY 1) to return to the main menu.
7. The control panel can now be disconnected from the drive.
Download All Parameters
To download all parameters from the control panel to the VFD,
perform the following procedure:
1. Install the control panel with the correct parameters onto the
VFD.
2. Select MENU (SOFT KEY 2). The main menu will be dis-
played.
3. Use the UP or DOWN keys to highlight PAR BACKUP on
the display screen and press ENTER (SOFT KEY 2).
4. Use the UP or DOWN keys to highlight DOWNLOAD TO
DRIVE ALL and press SEL (SOFT KEY 2).
