Field Set Up And Verification - Carrier AquaEdge 19XR Series Start-Up, Operation And Maintenance Instructions Manual

Field Set Up and Verification

IMPORTANT: Some parameters are specific to the chiller con-
figuration 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 configuration values
match the chiller parameter labels and Chiller Builder design data
sheet. See typical jobsite parameters in Tables 9 and 10. Different
service tables will need to be checked based on starter selection.
LABEL LOCATIONS
Verify the following labels have been installed properly and match
the chiller requisition:
• Surge Parameters — Located inside the chiller control
panel.
• Chiller identification nameplates — Located on the right
side of the control panel. A unit-mounted VFD alternate
information nameplate will have two additional labels.
(See Fig. 34.)
- External Machine Electrical Nameplate — located right
side of the VFD (See Fig. 35).
- Internal Machine Electrical Nameplate — located on
the inside of the left VFD enclosure door.
STARTER/DRIVE PROTECTION AND OTHER INCOM-
ING 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 wir-
ing to the starter are in accordance with NEC/CEC
(National Electrical Code/California Energy Commission)
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 the SCCR
(short circuit current rating) of the equipment marking.
5. Verify the power lugs in the starter/VFD and branch pro-
tection are properly secured. Inspect the ground cable and
ensure it is properly connected at the branch and to the
ground lug in the starter.
6. Verify the conduit for the power wiring in securely con-
nected to the starter flanged cover and runs continuously
to the branch protection.
7. Ensure the control and signal wires connected to the chiller
controller or the starter/VFD are in separate conduits.

Figures 36-39 show how the parameters defined below will affect
the configured surge line. The menu can be found under MAIN

RECTION CONFIG.
NOTE: Before tuning surge prevention, check for VFD speed lim-
itation or capacity overrides. If the source of low capacity is found
in one of these places, do not proceed with an attempt to tune the
Surge Prevention configurations.
If capacity is not reached
and
1. ACTUAL GUIDE VANE POSITION < GUIDE VANE
TRAVEL RANGE
and
2. SURGE PREVENTION ACTIVE = YES (can be identi-
fied in MAIN MENU
SURGE CORRECTION)
and
3. PERCENT LINE CURRENT < 100%
then the surge line is probably too conservative.
