Initially PQM II meters can beused as stand-alone units. Open architectureallows connection to other ModBus compatibledevices on the same communication link.At a later stage PQM II can be integrated in acomplete plant wide system for overall processmonitoring and control.1 a 11c0 0 110b0 1 0A2M P S1c 100 AMPSSTATUSSTATUSCOMMUNICATE RELAYSCOMMUNICATE ULATIONTX2SIMULATIONTX2AUX2AUX2ALARMTX1PROGRAMSELF TESTRX2SELF ENUAUX3ESCAPEESCAPEPower Quality MeterPower Quality MeterRESETRESETConnect two 4 to 20 mA transducers for process variable measurement and control.The standard PQM II comes complete with arear RS485 and front RS232 port. RS232 portcan be used for data collection, printing reportsor problem analysis without disturbing the mainRS485 communication interface at rear. Thestandard meter provides: RS485 ModBus 1,200 to 19,200‑bpsFuture ExpansionCommunicationsThe PQM II uses non-volatile flash memory forfirmware storage. This allows future productupgrades to be loaded via the serial port .Upgrades can also be downloaded from the GEMultilin website.Second Rear Comm Port: An additional rearRS485 comm port is provided for simultaneousmonitoring by process, instrument, electrical ormaintenance personnel.OptionsThree output relays and four inputs allowmeasured parameters from the standardPQM II to be combined with setpoints and I/Os for control applications. With the controloption, three output relays and four switchinputs are added along with programmableset points to make a mini RTU. Output relayscan also be controlled via the communicationport or assigned to different setpoints forcustom programming to accommodate manyapplications such as:There are a variety of options availableto the user, allowing a range of customconfigurations: DNP 3.0 Level 2 Protocol Mini RTU SCADA system component Measure actual valuesTransducer Read statusFour Analog Outputs: Four isolated analogoutputs can be used to replace eight analogtransducers.

PQM II Power Quality MeterHarmonic Analysis: Non linear loads such asvariable speed drives, computers and electronicballasts can cause harmonics which may leadto problems such as nuisance breaker tripping,telephone interference, transformer, capacitoror motor overheating. Harmonic analysis canbe used for fault diagnosis such as detectingundersized neutral wiring, need for a harmonicrated transformer, or effectiveness of harmonicfilters. Details of the harmonic spectrum are usefuland available with the power analysis option.Voltage Disturbance Recorder (VDR)The Voltage Disturbance Recorder (VDR) functionadds to the PQM II the ability to monitor andrecord Sag and Swell disturbances. It can recordup to 500 sag/swell events for all voltagessimultaneously.Waveform Capture: Voltage and currentwaveforms can be captured and displayed ona PC using the EnerVista program suppliedwith the PQM II or using third party software.Distorted peaks or notches from SCR switchingprovide clues for taking corrective action.TMEvent Recorder: Alarms, setpoint triggers,input and output events can be stored in a 150event record and time and date stamped bythe internal clock. This is useful for diagnosingproblems and system activity. Minimum andmaximum values are also continuously updatedand time stamped.Trace Memory: The PQM II can be configuredto record a maximum of 36 cycles of dataon all voltage and current inputs based onovervoltage, undervoltage, overcurrent orswitch input state change.EnerVista SoftwareEnerVista LaunchpadTMEnerVista Launchpad is a powerful softwarepackage that provides users with all of the setupand support tools needed for configuring andmaintaining GE Multilin Products.
