For example, Boyd’s recirculating chillers can monitor and communicate pressure changes. When a system is installed and operational, the existing pressure reading on the liquid side can be captured and used as a reference point to constantly monitor the pressure on the liquid side. If your equipment sees a sudden trend of increasing or decreasing pressure through any period of time or days, for example due to plumbing problems, corrosion or blocked filters, then you are alerted to any potential problem before it occurs.
Slow but steady changes in temperature are also indicators of problems to come. If a system is slowly losing its ability to maintain temperature during normal functioning, it could mean that the electronic components being cooled are overheating or not operating due to internal failures, or perhaps the chiller is losing performance. Boyd chillers have the capability of measuring temperature changes as small as 1/100 of a degree and communicating them through the RS232 interface.
The development of start-up system tests, or tests that can be run periodically using the measurement and control features of the chiller, is an extremely effective way of identifying problems before they occur and cause downtime. Measuring temperature, pressure and other parameters using the chiller's integral sensors and the RS232 interface avoids the expense and complication of integrating additional temperature and pressure sensors, and the early diagnosis and repair of faults or system problems saves money and downtime.
Download RS232 Communication Software and copy to your hard drive. Extract to a single folder (such as your desktop); do not extract the KodiakPCHost.cab file. Because of firewalls, please rename the setup.exr to setup.exe. Run the setup.exe file. If pop up displays a message saying a file on your system is newer than what is being installed, choose to keep the newest file. After that, make sure your com 1 port is set to 9600 baud, 8 data bits, 1 stop bit, no parity. Should be no software flow control as well. Please note, when extracting the zip file using WinZip, the version should be at least 9.0. The program is a simple interface to represent the main screen and controls. You must turn off your pop-up blocker to allow for downloads.
