4-7 Alarms

The controller is setup with multiple alarms, most of them configurable using the Supervisor password. Section 4-5 Controller Setpoints on page 41 gives a list of alarms that the controller is setup to display. The alarms are broken up into two categories – warnings and faults. The warning notifies the user that the parameter has been exceeded and the chiller is allowed to keep operating, but should be monitored to determine the cause of the warning. The fault notifies the user that the parameter has been exceeded and the chiller and pump has been shut down to protect the system.

4-8 Optional Communications

The communications function allows you to monitor and set the parameters by a program prepared and running on a host computer connected to the controller.

Serial communications use a RS-485 hardware interface. Protocols available are BACNet, LONWorks, CANBus, and ModBus RTU (Slave mode only). See Appendix for the controller data that is available through these protocols.

Network communications use a RJ-45 hardware interface using the basic Ethernet TCP/IP layer stack. Protocols available are BACNet (Ethernet, IP, or MS/TP) and ModBus IP. See Appendix for the controller data that is available through these protocols.
