PQMII POWER QUALITY METER – INSTRUCTION MANUAL 5–1PQMII Power Quality MeterChapter 5: SetpointsDigital EnergyMultilinSetpoints5.1 Introduction5.1.1 Setpoint Entry MethodsPrior to operating the PQMII, it is necessary to program setpoints to define systemcharacteristics and alarm settings by one of the following methods:• Front panel, using the keys and display.• Rear terminal RS485 port COM1 or COM2, or front RS232 port and a computerrunning the EnerVista PQMII Setup Software included with the PQMII, or from aSCADA system running user-defined software.Either of the above methods can be used to enter the same information. However, acomputer makes information entry considerably easier. Moreover, a computer allowssetpoint files to be stored and downloaded for fast, error-free entry. The EnerVista PQMIISetup Software included with the PQMII facilitates this process. With this software,setpoints can be modified remotely and downloaded at a later time to the PQMII. Refer to4.4: Using the EnerVista PQMII Setup Software for additional details.Setpoint messages are organized into logical groups or pages for easy reference.Messages may vary somewhat from those illustrated because of installed options, andmessages associated with disabled features will be hidden. This context sensitiveoperation eliminates confusing detail. Before accurate monitoring can begin, the setpointson each page should be worked through, entering values either by local keypad orcomputer.The PQMII leaves the factory with setpoints programmed to default values. These valuesare shown in all setpoint message illustrations. Many of these factory default values can beleft unchanged. At a minimum, however, setpoints that are shown shaded in 5.3.1: Currentand Voltage Configuration must be entered for the system to function correctly. As asafeguard, the PQMII will alarm and lock-out until values have been entered for thesesetpoints. The CRITICAL SETPOINTS NOT STORED alarm message will be displayed until thePQMII is programmed with these critical setpoints.
