Engineering Guide Specications
The Master Controller shall monitor and report the following
system parameters for the chiller system:
• Chilled water entering and leaving temperature
• Condenser water entering and leaving temperature
•
Any module failure condition shall cause a “fault”
indication at the Master Control Panel and shutdown
of that compressor circuit with the transfer of the load
requirements to the next available compressor circuit. In
the case of a system “fault” the entire chiller will be shut
down. When any fault occurs, the CoolLogic Control System
shall record conditions at the time of the fault, and store
the data for recall. This information shall be capable of
recall through the keypad of the Master Control Panel and
displayed on the 4 line by 40 character, back-lit LCD. A
history of faults shall be maintained including date and time
leaving chilled water reset control will insure that the
parallel evaporators are operated above the freeze point
for part load operation.
Factory Testing
Each remote air cooled chiller module shall be pressure-
tested, evacuated and charged with nitrogen.
