Alarm conditions can be set up for all measured quantities. These include overcurrent, undercurrent, neutral current, current unbalance, voltage unbalance, phase reversal, overfrequency, underfrequency, power factor, switch inputs, etc. The alarm messages are displayed in a simple and easy to understand English format. 1.2.3 Communications The PQMII is equipped with one standard RS485 port utilizing the Modbus or DNP protocols. 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. The PQMII also includes a front RS232 port which can be used for the following tasks: • data monitoring • problem diagnosis • viewing event records • trending • printing settings and/or actual values • loading new firmware into the PQMII 1.2.4 Future Expansion Flash memory is used to store firmware within the PQMII. This allows future product upgrades to be loaded via the serial port.

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.

Transducer Input/Outputs Four isolated 4 to 20 mA (or 0 to 1 mA depending on the installed option) analog outputs are provided that can replace up to eight transducers. The outputs can be assigned to any measured parameters for direct interface to a PLC. One 4 to 20 mA analog input is provided to accept a transducer output for displaying information such as temperature or water level. An additional rear RS485 communication port is provided for simultaneous monitoring by process, instrument, electrical, or maintenance personnel.

An additional three dry-contact form “C” output relays and four dry-contact switch inputs are provided. These additional relays can be combined with setpoints and inputs/outputs for control applications. Possibilities include: • undercurrent alarm warnings for pump protection • overvoltage/undervoltage for generators • unbalance alarm warnings to protect rotating machines • dual level power factor for capacitor bank switching • underfrequency/demand output for load shedding resulting in power cost saving • kWh, kvarh and kVAh pulse output for PLC interface • Pulse input for totalizing quantities such as kWh, kvarh, kVAh, etc.
