  • Page 19 METER CONFIGURATION 3.2.5 Setting the Real Time Clock The VerifEye meter includes a Real Time Clock. The clock is used only to time stamp Interval Data in the log, it is not used for calculation within the meter. For those customers using the IDR function of the meter, it is helpful (but not strictly necessary) to set the real time clock so that data records can be uniquely identified.
  • Page 20 METER CONFIGURATION 3.2.6 Retrieving Interval Data The VerifEye meter maintains an internal log of the energy data (Net kWh) for each channel in the meter. This log is updated every 15 minutes and is always active. The meter stores 63 days’ worth of 15 minute data in its memory. This data can be retrieved by users looking to restore gaps in data collection where RTUs may have been offline or communication has been interrupted.

  • Page 21: Meter Installation

    METER INSTALLATION This section is intended to support the physical installation of the meter and provide guidance on connecting the current transformers (CTs) correctly within the electrical load center and to the VerifEye meter. Meter Mounting Configurations VerifEye meters are sold in several form factors. Enclosures are designed to be wall mounted and connected to electrical conduit.

  • Page 30: Communication & Verification

    COMMUNICATION & VERIFICATION This section is intended to support the commissioning of the meter by an instrumentation technician. In many cases, the electrical installation is conducted ahead of the availability of the RTU or was performed by a different installer. Often the technician is working in concert with a remote programmer who is confirming the connectivity with a remote host system.
  • Page 31 COMMUNICATION & VERIFICATION Communication Verification NOTE: Verification includes confirmation of BOTH the physical interface settings (Serial or Ethernet) and the protocol (Modbus or BACnet) settings. The LCD User interface can be used to quickly confirm the settings required for each combination of interface and protocol. The interface is intuitive and groups together commonly associated registers.
  • Page 32 COMMUNICATION & VERIFICATION Physical Interface Verification Serial Setup Verification In a multidrop serial network, the host data format settings are typically known or specified and the slave is adjusted to match. In some cases (long wiring runs, etc.), it may be necessary to experiment in determining the fastest allowable baud rate for a given wiring configuration by changing BOTH the host and slave devices.

  • Page 33: Bacnet Mstp

    COMMUNICATION & VERIFICATION Modbus Settings Modbus RTU Settings Device Address: In a Modbus network each device must be assigned a unique slave address. Valid Modbus addresses are 1-240 (the VerifEye 48 channel meter requires 15 addresses beyond Element A). The slave address of the power meter sets the register address for Element A.
  • Page 34 COMMUNICATION & VERIFICATION Pulse Inputs Series 7200/7300 meters are equipped with 2 pulse inputs. Pulse counting supports accumulation of consumption data from any external meter using a dry contact (Form A Relay) or open collector outputs. The pulse inputs are compatible with “low speed”...
  • Page 35 COMMUNICATION & VERIFICATION 5.10 Access Restriction Limitations If security levels have been set up in the meter, no data is accessible through the LCD user interface, without entering the PIN credentials. NOTE: Protocols such as Modbus DO NOT SUPPORT ANY LEVEL OF security such that any network traffic acting as a master can retrieve and write data from the registers.
  • Page 36 PINs are also accessible as registers, but are encoded so that reading the value of the register through an RTU does not inform a user what the password is. This feature allows Leviton Manufacturing to support looking up forgotten PINs, if network access is available.
  • Page 37 COMMUNICATION & VERIFICATION 5.12 Verification of Installation Once the VerifEye meter is configured and communicating with the RTU, it is a good idea to perform some simple checks to ensure that all the CTs are on the correct voltage phases and that the CTs are facing the correct direction. The following are recommendations that work for typical installations.
  • Page 38 COMMUNICATION & VERIFICATION 5.12.2 Phase Checking by Phasor Plot When a CT is installed on the incorrect phase, the indicated current vector is pointing either 180 degrees away (a split phase system) or 120 degrees away (a three-phase system) from the true displacement angle. In the latter case, this usually causes a significant decrease in the reported power factor, even if the CT is also on backwards.
  • Page 39 COMMUNICATION & VERIFICATION 5.12.3 CT Orientation Check The VerifEye meter reports power and energy in each electrical quadrant under a different register. When CTs are installed backwards, the indicated current vector is oriented 180 degrees away from the true displacement angle. In accordance with standard definitions, the Wattage and VARs of the effected channel report with a sign opposite from what is expected.
  • Page 40 COMMUNICATION & VERIFICATION 5.13 Power Factor Convention Power Factor is the ratio of a signed number (true power) and an unsigned number (apparent power). This discrepancy has led to some customer confusion. The VerifEye meter allows users to select between two conventions (ANSI & IEEE).
  • Page 41 COMMUNICATION & VERIFICATION 5.15 Pre-Processing Aids The meter has several registers that can aid in pre-processing or post- processing data that otherwise may need seconday operations. Snap Thresholds The signal to noise ratio of the meter is above 80 db at full scale (1 part in 10,000).
