Quick Test (Service Test)
Main power and control circuit power must be on for Quick
Test. The Carrier Controller Quick Test function is used to ver-
ify proper operation of various devices within the chiller, such
as condenser fans, automated isolation valves, EXVs, and re-
mote alarm relays. This is helpful during the start-up procedure
to determine if devices are installed correctly.
To use the Quick Test mode, the unit must be in the local OFF
mode. To reach the Quick Test menu, follow the path: Main
Menu
Quick Test Table. The unit must be in Local Off
mode to adjust parameters in the table. The Quick Test function
is not available remotely, and can only be used from the Carrier
Controller display. See the Start-Up Checklist at the end of this
document, page CL-6, for a list of the parameters in the Quick
Test Table.
Example: Test the function of the Ckt A condenser fans
• Power must be applied to the unit. The Enable-Off-Remote
Contact switch must be in the OFF position.
• Touch the Start/Stop button and ensure the unit is in Local
Off.
• Navigate to the Quick Test table and set line 2 Quick Test
Enable to Enable.
• Set line 11, VariFan Speed A, to 100%, then select SET
from the pop-up menu to accept the entry. Confirm all fans
are running.
Test component function by turning the item values from OFF to
ON or adjusting the actuated percentage. These discrete outputs
are then turned off if there is no keypad activity for 10 minutes.
See Fig. 103 and 104 for component arrangement diagrams.
NOTE: There may be up to a one-minute delay before the se-
lected item is energized.
