This can be used to integrate process, instrumentation, and electrical requirements in a plant automation system by connecting several PQMII meters together to a DCS or SCADA system. A PC running the EnerVista PQMII Setup Software can change system setpoints and monitor values, status, and alarms. Continuous monitoring minimizes process downtime by immediately identifying potential problems due to faults or changes from growth.
Page 14: Open Architecture
1.2.5 Open Architecture PQMII units can initially be used as standalone meters. Their open architecture allows connection to other Modbus compatible devices on the same communication link. These can be integrated in a complete plant-wide system for overall process monitoring and control.

A and C to the phase B input on the PQMII. This causes the phase A and phase C current to flow through the PQMII’s phase B CT in the opposite direction, producing a current equal to the actual phase B current.
Page 41: Control Power
A universal AC/DC power supply is standard on the PQMII. It covers the range 90 to 300 V DC and 70 to 265 V AC at 50/60 Hz. It is not necessary to adjust the PQMII if the control voltage is within this range. A low voltage power supply is available as an option. It covers the range 20 to 60 V DC and 24 to 48 V AC at 50/60 Hz.
Page 42: Output Relays
2.2.7 Output Relays The basic PQMII comes equipped with one output relay; the control option supplies three additional output relays. The PQMII output relays have form C contacts (normally open (NO), normally closed (NC), and common (COM)). The contact rating for each relay is 5 A resistive and 5 A inductive at 250 V AC.
Page 43 The minimum pulse width required for the PQMII to read the switch is 150 ms. Therefore, for the PQMII to read one pulse, the switch input must be in its inactive state (closed/open) for a minimum of 150 ms then in its active state (open/ closed) for another 150 ms.
Page 44: Analog Outputs (Optional)
2.2.9 Analog Outputs (Optional) The PQMII has four current outputs when the transducer option is installed (T20 = 4 to 20 mA, T1 = 0 to 1 mA in the order code). These outputs can be multiplexed to produce 8 analog transducers.

COM1 is a RS485 port available at the rear terminals of the PQMII which is normally used as the main communications interface to the system.
Page 46 Therefore, it is imperative that the serial master and PQMII are both at the same ground potential. This is accomplished by joining the RS485 ground terminal (Terminal 46 for COM1;...

An RS232 communications port is also available for uploading or downloading information to the PQMII. 3.1.2 Display All messages are displayed in English on the 40-character liquid crystal display.
Page 50: Led Indicators
The LED status indicators provide a quick indication of the overall status of the PQMII. These indicators illuminate if an alarm is present, if setpoint access is enabled, if the PQMII is in simulation mode, or if there is a problem with the PQMII itself.

4.3.2 Saving Setpoints to a File Before upgrading firmware, it is important to save the current PQMII settings to a file on your PC. After the firmware has been upgraded, it will be necessary to load this file back into the PQMII.
Page 67 The EnerVista PQMII Setup Software now prepares the PQMII to receive the new firmware file. The PQMII will display a message indicating that it is in Upload Mode. While the file is being loaded into the PQMII, a status box appears showing how much of the new firmware file has been transferred and how much is remaining.
Page 68: Loading Saved Setpoints
A dialog box will appear to confirm the request to download setpoints. Click Yes to send the setpoints to the PQMII or No to end the process. The EnerVista PQMII Setup Software will load the setpoint file into the PQMII. If new setpoints were added in the firmware upgrade, they will be set to factory defaults.

Page 72: Trace Memory
4.5.3 Trace Memory The trace memory feature allows the PQMII to be setup to trigger on various conditions. The trace memory can record maximum of 36 cycles of data (16 samples per cycle) for all voltage and current inputs simultaneously. A Total Trace Triggers Counter has been implemented in the PQMII Memory Map at Register 0x0B83.
Page 73 Trace Memory Triggers from the last time power was applied to the PQMII. The Total Trace Triggers counter will rollover to 0 at 65536. The trace memory feature is implemented into the EnerVista PQMII Setup Software as shown below.
Page 74: Data Logger
4.5.4 Data Logger The data logger feature allows the PQMII to continuously log various specified parameters at the specified rate. The data logger uses the 64 samples/cycle data. This feature is implemented into EnerVista PQMII Setup Software as shown below.
Page 75 “Circulate”: when the data logger is full, it will start from the beginning and overwrite the previous data. The Log 1(2) Interval parameters determine how frequently the PQMII logs each piece of data. The total log size is approximately 192KB. The allotment of this memory can be varied between the two logs to maximize the overall log time.
Page 76: Voltage Disturbance Recorder
4.5.5 Voltage Disturbance Recorder The Voltage Disturbance Recorder allows the PQMII to monitor and record sag and swell disturbances. This function can record up to 500 sag/swell events for all voltages simultaneously. The events roll-over and old events are lost when more than 500 events are recorded.
Page 77 The Clear Events button clears the voltage disturbance recorder. Events are overwritten when the event recorder reaches 500 events. The Save button exports the events to a CSV format file. A text file viewer can open and read the file. PQMII POWER QUALITY METER – INSTRUCTION MANUAL 4–19...

INCORRECT CODE SETACCEN.CDR The factory default access code for the PQMII is 1. If three attempts are made to enable setpoint access with an incorrect code, the value of the setpoint access setpoint changes to “Disabled” and the above procedure must be repeated.
Page 91: Serial Ports
Once ACCESS: DISABLED setpoint access has been enabled, the PQMII display will return to the original setpoint message. If the control option is installed and one of the switches is assigned to “Setpoint Access”, the setpoint access switch and the software setpoint access will act as a logical ‘AND’.

Page 99 (256 samples/cycles, 1 cycle) causes the trace memory sampling to stop for one cycle whenever a harmonic analysis is requested. Refer to 4.5.3 Trace Memory for details on trace memory implementation in the EnerVista PQMII Setup Software. • TRACE MEMORY USAGE: The trace memory feature allows the user to capture maximum of 36 cycles.
Page 100 TRACE MEMORY TRIGGER DELAY: In some applications it may be necessary to delay the trigger point to observe the data before the fault occurred. The PQMII allows the trigger to be delayed by the amount of cycles set in this setpoint. Therefore, buffer will always contain the number cycles specified in this setpoint before the trigger point and the remaining space in the buffer is filled with the cycles after the trigger point.
