Carrier 19XR, XRV specifications

VERIFY VFD CONFIGURATION AND CHANGE PARAMETERS IF NECESSARY

IMPORTANT: The VFD controller has been factory con- figured for use and communications to the Chiller Visual Controller/International Chiller Visual Controller (CVC/ ICVC). Some parameters are specific to the chiller config- uration and will need to be verified prior to operation. Speed control and starting the drive have been disabled at the VFD keypad. All command functions must be initiated from the CVC/ICVC.

Using the Keypad — The keypad display is used to monitor, view fault history and adjust the program of the VFD microprocessor. It operates in two modes: Monitor mode and Program mode:

Use the ↑ and ↓ keys to:

•Step through the drive parameter menus and error log when the keypad/display is in Program mode.

•Increase or decrease a numeric value such as the refer- ence or parameter value.

•Hold down these keys to increase the scroll speed.

Use the ENTER softkey to:

•Display a parameter or a selection value in Program mode.

•Save a value.

•Move through each monitor display item when in Moni- tor mode.

Monitor Mode (Default Mode) — Specific drive conditions may be monitored on the keypad when in this mode. An LED will be illuminated next to the description of what is displayed on the keypad. Use the ENTER softkey to scroll through and monitor the following selections:

•All LEDs on — Speed request from the CVC/ICVC

•Motor Speed

•Output Frequency

•Output Voltage

•Output Current

Program Mode — This mode displays and modifies the con- figuration parameters of the VFD microprocessor. Particular parameters, parameter numbers, and error log information can be displayed when in Program mode.

Press the PROGRAM softkey until the PROGRAM LED is illuminated to enter the Program mode.

Use the ↑ and ↓ keys to move through the menus

Press ENTER softkey to select the desired menu.

Press ↑ and ↓ keys to move through following parameters.

P.nnn — General Parameters

U.nnn — Vector Control Parameters* H.nnn — Volts/Hertz Control Parameters R.nnn — RMI Remote Monitor Interface

Parameters

E.nnn — Error Log (See fault codes)

*Vector control is not used in this configuration.

Press ENTER softkey to select a parameter menu screen.

Press ↑ and ↓ keys to adjust the selected parameter.

Press the PROGRAM softkey until the PROGRAM LED turns off to exit the program.

Changing parameters may adversely affect chiller operation.

Accessing Password Protected Parameters — Although the VFD controller has been preconfigured as the factory, the user will need to be able to access the parameters to verify the job specific parameters are correct, tune the controller or correct a problem. The two passwords protecting the VFD configuration are Parameter Set Display password and Program Disable password. The Parameter Set Display password restricts view- ing. P.nnn parameters above 007 and all H.nnn and R.nnn screens. The password can be accessed at parameter P.006 and will switch between enabled and disabled each time the pass- word 107 is entered. The Program Disable password restricts the changing of the drive parameter set. To enable or disable changes select parameter P.051 and enter the password 26.

NOTE: Some of the parameters can be changed only when the drive is stopped.

It is the operator’s responsibility to distribute access to the passwords. Carrier is not responsible for unauthorized access violations within the operator’s organization. Failure to observe this warning could result in bodily injury.

See the Initial Start-Up Checklist section for VFD Job Specific Configuration table. For job specific parameters see inside of the VFD enclosure door, next to the keypad. Refer to the VFD Configuration table for the entire list of parameters.

Restoring the default parameter P.050 will require all the Carrier default parameters to be restored manually.

VFD CHILLER FIELD SET UP AND VERIFICATION

Label Locations — Verify the following labels have been installed properly and match the chiller requisition:

•Surge parameters — Located inside the control panel.

•Chiller identification nameplate — Located on the right side of the control panel.

•VFD Parameter — Located to the right of the VFD con- troller keypad on the VFD module.

•VFD Nameplate — Located on the right side of the VFD as viewed from its front.

•Record all nameplate information on the Reliance Con- figuration sheet.

Drive Protection and Other Incoming Wiring

1.Verify that the branch disconnects or other local discon- nects are open and properly tagged out.

2.Verify that the branch circuit protection and AC input wiring to the VFD are in accordance with NEC/CEC (National Electrical Code/California Energy Commis- sion) and all other local codes.

3.Verify that the fuses are per the field wiring diagram.

4.Verify that the incoming source does not exceed 85 kA.

5.Verify the power lugs in the VFD and branch protection are properly secured. Inspect the ground cable and ensure it is properly connected at the branch and to the ground lug in the VFD.

6.Verify the conduit for the power wiring in securely con- nected to the VFD flanged cover and runs continuously to the branch protection.

7.Verify that the incoming and outgoing wires have been properly connected inside of the reactor enclosure if a separate line reactor has been added to the chiller.

8.Ensure the control and signal wires connected to the chill- er controller or the VFD are in separate conduit.
