Installation

Disconnect power prior to installation.

Reinstall any covers that are displaced during the installation before powering the unit.

Mount the meter in an appropriate electrical enclosure near equipment to be monitored.

Do not install on the load side of a Variable Frequency Drive (VFD), aka Variable Speed Drive (VSD) or Adjustable Frequency Drive (AFD).

Observe correct CT orientation.

The meter can be mounted in two ways: on standard 35 mm DIN rail or screw-mounted to the interior surface of the enclosure.

A. DIN Rail Mounting

1. Attach the mounting clips to the underside of the housing by sliding them into the slots from the inside. The stopping pegs

must face the housing, and the outside edge of the clip must be ush with the outside edge of the housing.

2. Snap the clips onto the DIN rail. See the diagram of the underside of the housing (below).

Clip ﬂush with outside edge

3. To reduce horizontal shifting across the DIN rail, use two Veris AV02 end stop clips.

B. Screw Mounting

1. Attach the mounting clips to the underside of the housing by sliding them into the slots from the outside. The stopping pegs

must face the housing, and the screw hole must be exposed on the outside of the housing.

2. Use three #8 screws (not supplied) to mount the meter to the inside of the enclosure. See the diagram of the underside of the

The meter has a number of dierent possible system wiring congurations (see Wiring Diagrams section). To congure the meter, set the System Type via the User Interface or Modbus register 130 (if so equipped). The System Type tells the meter which of its current and voltage inputs are valid, which are to be ignored, and if neutral is connected. Setting the correct System Type prevents unwanted energy accumulation on unused inputs, selects the formula to calculate the Theoretical Maximum System Power, and determines which phase loss algorithm is to be used. The phase loss algorithm is congured as a percent of the Line-to-Line System Voltage (except when in System Type 10) and also calculates the expected Line to Neutral voltages for system types that have Neutral (12 & 40).

Values that are not valid in a particular System Type will display as “----” on the User Interface or as QNAN in the Modbus registers.

Fuse Recommendations

Keep the fuses close to the power source (obey local and national code requirements).

For selecting fuses and circuit breakers, use the following criteria:

• Select current interrupt capacity based on the installation category and fault current capability.

• Select over-current protection with a time delay.

• Select a voltage rating sucient for the input voltage applied.

• Provide overcurrent protection and disconnecting means to protect the wiring. For AC installations, use Veris AH02,

AH03, AH04, or equivalent. For DC installations, provide external circuit protection. Suggested: 0.5 A, time delay fuses.

• The earth connection is required for electromagnetic compatibility (EMC) and is not a protective earth ground.

Set Pulse:

The System Type , CT size, PT Ratio, and System Voltage must all be configured before setting the Pulse Energy. If any of these parameters are changed, the meter will hunt for a new Pulse Duration, but will not change the Pulse Energy. If it cannot find a solution, the meter will display the wrench, show “ConF” in the ALARM -> PULSE screen, and enable Energy pulse output configuration error bit in the Modbus Diagnostic Alert Bitmap (if

When moving down to a smaller energy, the meter will not allow the selection if it cannot find a pulse duration that will allow the pulse output to keep up with Theoretical Maximum System Power (see S_PWR screen). When moving up to a larger energy, the meter will jump to the first value where it can find a valid solution. mS/P – Minimum Pulse Duration Time: This read only value is set by the meter to the slowest duration (in mS per closure) that will keep up with the Theoretical Maximum System Power. The open time is greater than or equal to the closure time. The maximum Pulses Per Second (PPS) is shown in yellow.

Set Demand Interval: INTRV - The number of Sub-Intervals (1 to 6) in a Demand Interval.

Default is 1 (block demand). SEC - Sub-Interval length in seconds. Default is 900 (15 minutes). Set to 0 for external sync-to-comms (Modbus units only).

Data Logging (EC only)

The E51C3 includes a data logging feature that records 10 meter parameters, each in its own buer.

Conﬁguration

Use register 150 to set the data logging time subinterval. Writing to the storage buer is triggered by the subinterval timer. The default subinterval is 15 minutes (at a 15 minute interval setting, the buers hold 60 days of data). An external timer can be used over Modbus by setting this register to 0.

Use register 159 to turn on data logging and select either Single Shot or Continuous mode. (default is data logging on, Continuous mode). In Single Shot mode, the meter records data until the buer is full. When the buer is full, the meter stops recording new readings. Data for this time period is kept, but newer energy information is lost. In Continuous mode, the meter continues to record energy data as long as the meter is operating. The buer can only hold 5760 entries at one time, however, so when the number of records exceeds 5760, the oldest entry is deleted to make room for the newest.

Registers 169-178 contain the pointers to 10 data storage buers. Each buer is user-congurable with the Modbus address of the 16-bit data output to be stored. 32-bit data, such as oating point data or 32-bit integer energy accumulators, require two buers. However, the lower 16 bits of an integer energy accumulator can be stored in a single buer (optional).

When the E51C3 is rst installed, the buers contain QNAN data, with a value of 0x8000. This data is considered invalid. If the buer is reset at any point, all entries in the buers are overwritten with this 0x8000 value, indicating that it is invalid. All invalid data is overwritten as the meter lls the buer with new data entries.

Reading Data

Use register 158 to choose which buer to read. When this register value is set to 0, the meter is in data logging mode. Changing this value from 0 to (1 through 10)switches the meter to reading mode and selects a buer to read. Data from the selected buer appears in registers 8000 to 13760.

Data Logging (EC only, cont.)

Modbus Point Map Overview

Read/Write Collision

If the demand sub-interval timeout occurs while the user is reading a page (register 158 ≠ 0), the log data will be held in RAM until the next demand subinterval. At that time, both the saved data from the previous cycle and the new data will be written to the log, whether the page register has been set back to 0 or not. Error bits in the Log Status Register (160) track these conditions. Subsequent log writes will proceed normally. Provided the log read is concluded in less time than the demand sub-interval, this mechanism handles the occasional collision and prevents the user from reading data as the buer is being updated.

The Log Status Register has additional error ag bits that indicate whether logging has been reset or interrupted (power cycle, etc.) during the previous demand sub-interval, and whether the Real-Time Clock has been changed (re-initialized to default date/ time due to a power-cycle or modied via Modbus commands).

The E51C2 Full Data Set (FDS) model features data outputs such as demand calculations, per phase signed watts VA and VAR, import/export Wh and VAh, and VARh accumulators by quadrant. The E51C3 Data Logging model includes the FDS and adds log conguration registers 155-178 and log buer reading at registers 8000-13760. The meter supports variable CTs and PTs, allowing a much wider range of operation from 90V x 5A up to 32000V x 32000A. To promote this, the meter permits variable scaling of the 16-bit integer registers via the scale registers. The 32-bit oating point registers do not need to be scaled.

Integer registers begin at 001 (0x001). Floats at 257 (0x101). Conguration registers at 129 (0x081). Values not supported in a particular System Type conguration report QNAN (0x8000 in Integer Registers, 0x7FC00000 in Floating Point Registers). Register addresses are in PLC style base 1 notation. Subtrac t 1 from all addresses for the base 0 value used on the Modbus RS-485 link.

PT Ratio: The meter scales this value by 100 (i.e. entering 200 yields a potential transformer ratio of 2:1).

The default is 100 (1.00:1), which is with no PT attached. Set this value before setting the system voltage (below)

System Voltage: This voltage is line to line, unless in system type 10 (register 130), which is line to neutral.

The meter uses this value to calculate the full scale power for the pulse conguration (below), and as full scale for phase loss (register 142). The meter will refuse voltages that are outside the range of 82-660 volts when divided by the PT Ratio (above).

Theoretical Maximum System Power – This read only register is the theoretical maximum power the meter

expects to see on a service. It is calculated by the meter from the System Type (register 130), CT size (register

131), and System Voltage (register 134) and is updated whenever the user changes any of these parameters. It is used to determine the maximum power the pulse outputs can keep up with. This integer register has the same scale as other integer power registers (see register 140 for power scaling).

Phase Loss Voltage Threshold in percent of system voltage (register

134). Default value is 10 (%). Any phase (as congured in register

130) whose level drops below this threshold triggers a Phase Loss alert, i.e., if the System voltage is set to 480 V L-L, the L-N voltage for each phase should be 277 V. When the threshold is set to 10%, if any phase drops more than 10% below 277 V, (less than 249 V), or if any L-L voltage drops more than 10% below 480 V (less than 432 V) the corresponding phase loss alarm bit in register 146 will be true.

Phase Loss Imbalance Threshold in Percent. Default is 25% phase

to phase dierence. For a 3-phase Y (3 + N) system type (40 in register 130), both Line to Neutral and Line to Line voltages are tested. In a 3-phase  System type (31 in register 130), only Line to Line voltages are examined. In a single split-phase (2 + N) system type (12 in register 130), just the line to neutral voltage are compared.

Pulse Contact Closure Duration

in msec. Read-only. Set to the slowest duration that will keep up with the theoretical max. system power (register

If the read condition is not removed the meter continues to write the log data as it normally would.

This bit is cleared to 0 on the rst demand interval with Logging Page Register = 0. Bit 3: Logging Reset – The log has been reset during the previous demand sub-interval. Bit 4: Logging Interrupted – Logging has been interrupted (power cycled, log conguration change, etc.)
