5.8.4 Field Set Up and Verification
IMPORTANT: Some parameters are specific to the chiller configuration and will need to be verified prior to
operation. All command functions must be initiated from the HMI.
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:
• Chiller identification nameplate — Located on control panel.
• VFD Nameplate data - located on the VFD.
MODIFY EQUIPMENT CONFIGURATION IF NECESSARY
— 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 Troubleshooting guide for more details about these functions;
see the Control Panel Schematic for field wiring.
5.9 Perform a control test (quick calibration / quick test)
Check the safety controls status by performing an automated controls test. First, perform a Quick Calibration Test
(Path Main Menu→ Quick Calibration. This is required for all modulating analog actuators. Upon successful
calibration go Main
Menu → Quick Test and verify operation on desired components. Note that this is a very
useful feature for troubleshooting. (The QUICK TEST screens can only be accessed when the chiller is in STOP
mode.) On the QUICK TEST table screen, select a test to be performed.
The Quick Test checks all outputs and inputs for proper functionality. In order to successfully proceed with the
controls test, the compressor must be off, no alarms showing, and voltage should be within ±10% of rating plate
value. Each test asks the operator to confirm the operation is occurring and whether or not to continue. If an error
occurs, the operator can try to address the problem as the test is being done or note the problem and proceed to
the next test.
If during the control test the guide vanes do not open, check the low pressure alarm, which shall not be active. (An
active low pressure alarm causes the guide vanes close.)
The refrigerant pump test will not energize the refrigerant pump if cooler pressure is below
–89.63 kPa.
When the controls test is finished the test stops and the QUICK TEST menu displays. If a specific automated test
procedure is not completed, access the particular control test to test the function when ready. Disable the Quick
Test feature when testing is complete.
