Operator Interface

Figure 21. DynaViewmain processor

DynaViewpresents three menu tabs across the top which are labeled “MAIN, REPORTS, and SETTINGS”.

The Main screen provides an overall high level chiller status so the operator can quickly understand the mode of operation of the chiller.

The Chiller Operating Mode will present a top level indication of the chiller mode (Auto, Running, Inhibit, Run Inhibit, etc.) The “additional information” icon (arrow) will present a subscreen that lists in further detail the subsystem modes. (See Machine Operating Modes.)

Main screen content can be viewed by selecting the up or down arrow icons. The Main screen is the default screen and after an idle time of 30 minutes.

The DynaView(DV) Operator Interface contains the “Main Processor (MP)” and is mounted on the unit control panel front door where it communicates commands to other modules, collecting data, status and diagnostic information from the other modules over the IPC (Inter Processor Communications) link. The Main Processor (MP) software controls water flows by starting pumps and sensing flow inputs, establishes a need to heat or cool, performs pre-lube, performing post-lube, starts the compressor(s), performs water temperature control, establishes limits, and pre-positions the inlet guide-vanes.

The MP contains non-volatile memory both checking for valid set points and retaining them on any power loss. System data from modules (LLID) can be viewed at the DynaViewoperator interface. Such as evaporator and condenser water temperatures, outdoor air temperature, evaporator and condenser water pump control, status and alarm relays, external auto-stop, emergency stop, evaporator and condenser water pressure drops and evaporator and condenser water flow switches.
