The meter has a number of dierent possible system wiring congurations (see Wiring section). To congure 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 congured 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 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 sucient 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 Phase Loss:
VOLTS - Phase Loss Voltage: The fraction of the system
voltage below which Phase Loss Alarm is on. For system
types with neutral, the Line to Neutral voltage is also
calculated and tested. If the System Voltage is 600 and the
fraction is set to 0.10, then the Phase Loss threshold will be
60 volts.
IMBAL - Phase Loss Imbalance: The fractional difference
in Line to Line voltages above which Phase Loss Alarm is
on. For system types with neutral, the Line to Neutral
voltages are also tested. For system types 1+N (10) and 2
(11) , imbalance is not tested.
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
1
equipped).
2
Wh/P - Set Pulse Energy: In Watt Hours (& VAR Hours, if
5
present) per Pulse. 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-tocomms (Modbus units only).

Data Logging
(ECA only)
The E50C3A includes a data logging feature that records 10 meter parameters, each in its own buer.
Configuration
Use register 150 to set the data logging time subinterval. Writing to the storage buer is triggered by the subinter val timer. The
default subinterval is 15 minutes (at a 15 minute interval setting, the buers 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 buer is full. When the buer 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 buer 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 buers. Each buer is user-congurable 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 buers.
However, the lower 16 bits of an integer energy accumulator can be stored in a single buer (optional).
When the E50C3A is rst installed, the buers contain QNAN data, with a value of 0x8000. This data is considered invalid. If the
buer is reset at any point, all entries in the buers are overwritten with this 0x8000 value, indicating that it is invalid. All invalid
data is overwritten as the meter lls the buer with new data entries.
Reading Data
Use register 158 to choose which buer 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 buer to read. Data from the selected buer
appears in registers 8000 to 13760.

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 buer 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 modied via Modbus commands).

Overview
The E50C2A Full Data Set (FDS) features data outputs such as demand calculations, per phase VA and VAR, and VAh VARh
accumulators. The E50C3A data logging model adds conguration registers 155-178 and buer reading at registers 8000-13760.
For security reasons, conguration and resets on all E50 models are protected by a user congurable passcode. The meter supports
variable CTs and PTs, allowing a much wider range of operation from 90V x 5A up to 32000V x 5000A. 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). Conguration registers at 129 (0x081). Values not supported in a
particular System Type conguration will report QNAN (0x8000 in Integer Registers, 0x7FC00000 in Floating Point Registers).

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, except for system type 10 which is line to neutral. The meter uses
this value to calculate the full scale power for the analog outputs and pulse conguration (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 value is the theoretical max. power the meter can expect to
see on a service. This value is 100% of scale on the analog output (0-5 VDC or 4-20 mA), if equipped. The meter
recalculates this value if the user changes the CT size, system type, or system voltage. This integer value has
the same scale as other integer power registers (see register 140 for power scaling).

Scale Factor I (Current)
Phase Loss Voltage Threshold in percent of system voltage (register
134). Default is 10 (%). Any phase (as congured in register 130)
that 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 dierence. 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 keeps
up with the theoretical max.
system power (register 135).
The open time ≥ the closure
time, so the max. pulse rate
(pulses per sec) is the inverse of
double the pulse time.
Scale Factors
Note: These registers contain a signed
integer, which scales the corresponding
integer registers. Floating point registers
are not scaled. Scaling is recalculated
when the meter conguration is changed.

Logging Read Page Register. Selects which of the Register Logs to read (see registers 169-178). 1-10 are valid
entries that put the meter into log reading mode, temporarily pausing logging. When set to 0 (no variable
selected for reading), normal logging resumes. The meter will buer one set of log entries while in reading
mode if a sub-interval timeout occurs (read/write collision). Default is 0.
Warning: this buered data will be written to the log and logging will resume on the following sub-interval
timeout whether the page register has been cleared or not, resulting in the appearance of data moving in the
buer during reads. To avoid this, log buer reads should be completed and this register set back to 0 in less
time than the Demand Sub-interval (preferred) or logging should be halted by setting Bit 1 in register 158
(logs may be missed)
Logging Conguration Register (Bit Mapped):
Bit 0: Clear to 0 for Continuous log buer mode. Set to 1 for Single Shot logging mode. Default is 0 (Continuous).
Bit 1: Clear to 0 to enable Logging. Set to 1 to halt logging. Default is 0 (Log).

Logging Status Register (Bit Mapped):
Bit 0: Log buer full – Set to 1 when one single shot mode has lled the log buer. The Logged Entry Count will
continue to increment. Cleared to 0 when logging is restarted (see reset command register 129).
Bit 1: Log Buer Read Collision 1 – Set to 1 if the meter tried to save log data while the user was reading the
log (Logging Page Register has been set to something other than 0). On the rst collision, the meter holds the
data until the next sub-interval and then writes the saved data to the log as well as the data for that interval.
This bit is cleared to 0 on the rst demand interval with Logging Page Register = 0.
Bit 2: Log Buer Read Collision 2 – Set to 1 on the 2nd attempt to save log data while the user is reading the log

(Logging Page Register is set to something other than 0). At this point the meter ignores the read condition
and does a double write, rst of the values saved from the previous cycle, and then the present values. 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 conguration change, etc.) during
the previous demand sub-interval.
Bit 5: RTC Changed – The Real Time Clock has been changed during the previous demand sub-interval.
Bit 6: RTC Reset – The Real Time Clock has been reset to the year 2000 and needs to be re-initialized.
Log Buer Wrap / Missed Log Counter. In continous mode, this counter increments each time the internal
circular log buer wraps and overwrites old data. The total number of logged entries since the last log reset is:
(Register 161 x 5760) + Register 163. In single shot mode this counter is the number of log entries lost due to
the buer being full. The counter is cleared on logging reset.
Max Number of Logging Days. Based on the Sub-Interval Length and the depth of the log buer, this register
shows the maximum number of days that data will be logged following a reset until the Buer is full (Single
Shot Mode) or overwrites old data (Continuous).
Number of Logged Entries since the log buer wrapped or was reset. In single shot mode, this is the total
number of valid entries in the buer. Any entries beyond this will read back as QNAN (0x8000).
