Field Set Up and Verification
Use the HMI touch screen to confirm that the VFD values
match the chiller parameter labels and Chiller Builder design
data sheet. The VFD values can be located from MAIN
MENU CONFIGURATION MENU.
LABEL LOCATIONS — Verify the following labels have
been installed properly and match the chiller requisition:
• Surge Parameters — Located inside the HMI chiller con-
trol panel.
• Chiller identification nameplate — Located on the left
side of the control panel. (See Fig. 28.)
• VFD Nameplate data - located on the right side of the VFD.
MODIFY EQUIPMENT CONFIGURATION IF NECES-
SARY — The EQUIPMENT SERVICE table has screens to
select, view, or modify parameters. Carrier’s certified drawings
have the configuration values required for the jobsite. Modify
these values only if requested. Modifications can include:
• Chilled water reset
• Entering chilled water control (Enable/Disable)
• 4 to 20 mA demand limit
• Auto restart option (Enable/Disable)
• Remote contact option (Enable/Disable)
See the 19DV with PIC5 Controls Operation and Trouble-
shooting guide for more details about these functions; see the
Control Panel Schematic for field wiring.
