E31xY63 Series
Branch Circuit Power Meter with Split-Core CTs
Product Overview
*
*The CE mark indicates RoHS2 compliance. Please refer to the CE Declaration of
Conformity for additional details.
The E31 Series Branch Circuit Power Meter is designed to measure the current, and on some models voltage, and
energy consumption of up to 92 circuits (84 branch circuits, 2 3-phase mains, 2 neutrals) on a single board. One E31
can monitor up to two panels. The E31xY63 model includes a main circuit board and two adapter boards mounted
to a single plate, with custom designed flat ribbon cables connecting the main board to the two adapter boards. Up
to 42 split-core CTs (50A 100A, or 200A, sold separately) allow the E31xY63 to monitor up to 42 branch circuits. Each
conductor passes through a current sensor and terminates at the breaker. Each sensor transmits the current data to
the data acquisition board.
The E31xY63 can be expanded to monitor 84 branch circuits by adding two additional adapter boards, two ribbon
cables, and 42 additional split-core CTs. However, these parts must be purchased and mounted separately. When
fully equipped, the E31 system measures the current, voltage, and energy consumption of up to 92 circuits (84
branch circuits, two 3-phase mains, two neutrals) with eight auxiliary inputs on a single board. One E31 system
can monitor up to two panels. The E31 can easily accommodate different panel configurations, including any
combination of multi-phase breaker positions, voltage phase mapping, and breaker sizes. To configure the E31 for
operation, download the NetConfig configuration software tool and the E3x Commissioning Guide from the Veris
website at www.veris.com/modbus_downloads.
Data is transmitted using an RS-485 Modbus protocol. The data acquisition board requires two addresses, one for
each set of 42 current sensors and four auxiliary inputs. Data is updated roughly every two seconds. As a circuit
approaches the user-defined threshold, the E31 activates the alarm indicators.
The E31A measures both current and power for the mains and branch circuits. The E31B measures both current and
power for the mains, and current only for each branch circuit. The E31C measures current only for the mains and
branch circuits.

E31xY63 Series Installation Guide
Data Outputs
TM
The E31 provides several types of measurements that give a comprehensive view of power consumption for every monitored load
on the panel (the table below shows which measurements are offered on each model):
• Real-time measurements: A live and up-to-date view of present power levels and the factors that affect them.
• Demand measurements: Averages of values measured over a specified time interval. The time interval (typically
15 minutes) can be set from 10 seconds to more than a day. The demand calculation can be configured to use single
intervals or the sliding average of up to 6 sub-intervals. Demand measurements are useful for tracking or graphing
load levels over time to correlate with total energy consumption.
• Historic maximum measurements: These measurements store the largest value recorded for a specific measurement
since the last time they were cleared. They are useful for identifying peak levels critical to equipment sizing or demand
limits in utility agreements.
• Accumulated energy measurements: Ongoing totals of cumulative energy used since the last time the value was
cleared. Energy values provide the informational basis for billing, cost allocation, carbon offset, BTU equivalent
calculations, and other applications of overall energy use.
• Energy snapshots: Energy totals that only change when the demand intervals are updated. They are samples of the
free-running energy accumulators at the end of each demand interval, as configured by the user. These provide energy
readings that are easily correlated to the demand values to simplify the tasks of sub-billing and cost allocation.
• Alarms: Provide a warning of excessively high or low current on each branch and aux channel. The user can set two
high-level and two low-level thresholds, and a delay time for latching alarms. Alarms are reported as both non-latched
events and latched events. Non-latching alarms are active while the current exceeds the threshold, but go inactive if
the current returns to a level within the specific thresholds. Latching alarms become active when the current exceeds
the threshold for a time period greater than the specified delay and remain active until they are cleared remotely.
Alarm status can be polled via any protocol. Via BACnet, Subscribe_COV can be used to generate alarm notifications.
Via SNMP, alarms drive SNMP event notifications.
Advanced Features - The E31 supports a number of advanced features. Some are always active, and others are configured
manually via Modbus register 62017, BACnet object AV164, or SNMP MIB variable “spanels/panel1/p1Configuration/p1Setup/
p1UserDefinedSettings” (OID .1.3.6.1 .4.1.40845.1.30.1.1.6.3.4.0). For models with 42 channels or more, these features are
configured independently for each panel.
• Logical meter support: The E31 can be configured to map any set of 1, 2 or 3 channels that are adjacent in the panel
to a logical meter, referred to in the point map as a logical circuit, that provides accurate multi-phase measurement
totals. Map these logical circuits by writing the desired logical circuit number into a set of registers/data objects
provided for each branch and aux channel (per panel).
• The channels assigned to each logical circuit must be adjacent in the panel (usually used for multi-phase breakers), but
there are no limitations on where those adjacent channels are aligned in the panel (any position where a multi-phase
breaker can be installed). This functionality is always active, but a user selection affects the how the data can be
accessed via Modbus. Measurement data via Modbus for logical circuits is presented in two ways, arranged either by
logical circuit number (looks more like a collection of individual meters) or by measurement type (arranged similar to
the single-phase data section of the point map).
• Legacy point map or alternate logical circuit point map: The E31 can be configured to select a preferred version of the
Modbus registers in the address range 4000 to 9999. If enabled (default), the logical circuits by measurement type is
active. Otherwise, the legacy point maps for 2-phase and 3-phase breakers used in E3x models with a firmware version
earlier than 1.023 is active. The logical circuits functionality can also be accessed via the “Logical Circuits by Circuit”
section of the point map (address range 10000 to 45000), regardless of the state of this selection.
• Phase angle measurements: The E31 measures the phase angle of every voltage and current input and presents these
measurements (in degrees) in additional data registers/objects. These values are used to verify that current inputs are
assigned to the proper voltage phases and to help determine how power factor variations are influenced by current
phase changes vs. harmonic distortion. Phase angle measurements are instantaneous and always active.
• User CT phase assignment: In the default mode, the E31 assigns each channel to the corresponding phase that most
3-phase panels implement, so that the user does not have worry about it. The user can opt to replace this selfassignment paradigm with a mode that allows explicit specification of the phase assignment for each channel. The
explicit assignments set by the user are stored by the E31 in non-volatile memory.
• Phase angle reference: The E31 measures the phase angle of every current and voltage input. The user can select
whether the phase angles are stated relative to an absolute reference (the phase angle of voltage input V1) or relative
to the voltage phase assigned to that specific current input channel.
• Signed power: Users can configure the E31 to report power as a signed value indicating whether the power is currently
being delivered (imported from the grid) or received (exported to the grid) for channels with generation sources
or bi-directional (regenerative) loads. When signed power is disabled, the energy accumulators include all energy

measured, regardless of direction. When signed power is enabled, the energy accumulators only include all energy
delivered (imported from the grid).
• Signed power factor: By default the E31 reports power factor as an unsigned value. The user can set it to report as a
signed value, where the sign indicates whether the current phase angle leads or lags the corresponding voltage phase.
• Demand/snapshot time interval source: The E31 offers two mechanisms for driving the demand/snapshot time
interval, an interval timer or an RTC (real-time clock). The legacy mode (default) uses an interval timer that does not
need to be set to an absolute time. When using the interval timer the demand/snapshot interval can be set from
10 to 32767 seconds (over 9 hours). An alternate mode utilizes an RTC set to a specific date and time to synchronize
the results with a larger system. The RTC must first be set in order to run and capture demand values and energy
snapshots. When power is interrupted, the RTC resets to a default date and time and must be set again in order to run.
When using the RTC, the demand/snapshot interval can be set from 10 to 3600 seconds (1 hour).

Wiring
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR
ARC FLASH
• While removing or installing panels and covers, assure that
they do not contact an energized bus.
• NEVER bypass external fusing.
• NEVER short the secondary of a potential transformer.
• Before closing covers and doors, carefully inspect the work
area and remove any tools, wire scraps or other objects that
may have been left inside the equipment.
Failure to follow these instructions will result in death
or serious injury.
For all steps in this section, when tightening terminals, apply the correct torque.
Aux CT inputs on main board: 3.5 to 4.4 in-lb (0.4 to 0.5 N-m); removable connectors on main board: 4.4 to 5.3 in-lb (0.5 to 0.6
N-m); terminals on Branch CT adapter boards: 1.9 to 2.2 in-lb (0.22 to 0.26 N-m).

1. Connect 2-wire 90 to 277 Vac power to main power terminals. Observe polarity. For the E31A and E31B, connect voltage lines
to the voltage taps (Figure 8). Provide overcurrent protection and disconnecting means to protect the wiring. Use Veris AH02,
AH03, AH04, or equivalent. Suggested: 0.5 A, time delay fuses.

120 V/240 V Delta High Leg (where the center tap of one of the three phase-to-phase transformers is grounded): the E3x supports
these applications, as long as the line-to neutral voltage [especially of the High Leg] does not exceed 300 Vac (as in North American
120/240 V High Leg Delta configurations).
In 3-wire (ungrounded) Delta applications, the E3x supports these applications with the following caveats:
Control Power for the meter cannot exceed 277 Vac. In applications where the L-L voltage is 277 Vac or less (e.g. 208 V line-toline) it can be connected to two of the phases being monitored without exceeding the limit. For higher voltages (e.g. 480 V
line-to-line), this must be supplied from a source that is 277 Vac or less. It could be a separate source or a transformer can be
used to step it down from two of the phases being measured.
All of the CT inputs (both branches and Aux inputs) are neutral-referenced. One side of each CT is essentially connected directly
to the neutral voltage input. If this is left floating, the solid-core CT strips, split-core CT adapter boards and all CTs will float at
the same potential (while the panel is energized). This does not present a risk to the equipment as long as it is within 300 V
of ground, but should be considered from a safety perspective in the overall application. The E3x will provide measurements
in this application with the accuracy specified, with the exception of line-to-neutral voltages, which will be calculated and
reported, based on a derived virtual neutral voltage, even though they are not relevant.
Corner-grounded delta: the E3x does not support these applications at any voltage level.
The E3x supports all 4-wire Wye, 3-wire split-phase and 2-wire single phase and configurations that operate between 90 and 300
Vac line-to neutral.

2. Address Configuration: Each Modbus device on a single network must have a unique address. Set the switch block to assign
a unique address before the device is connected to the Modbus RS-485 network. If an address is selected that conflicts with
another device, neither device will be able to communicate.
3. The E31 uses two logical addresses. Panel 1 uses the base address as set on the DIP switches, and Panel 2 uses this base address
+ 1. Address the E31 as any whole number between and including 1-246. Each unit is equipped with a set of eight DIP switches
for addressing. See below.

Problem
Solution
Product is not communicating over Modbus daisy chain
• Check the unit Modbus address to ensure that each device on the daisy
chain has a unique address.
• Check Parity.
• Check the communications wiring.
• Check that the daisy chain is properly terminated.
RX LED is solid
• Check for reversed polarity on Modbus comms.
• Check for sufficient biasing on the Modbus bus. Modbus physical
specification calls for 450-650 Ω biasing. This is usually provided by the
master.
The main board has a fast flashing amber light
• Verify ribbon cable connectors are inserted in the correct orientation.
• If cables are correct, reset main board to re-initialize product.
The main board has a slow flashing amber light
• One or more channels is clipping. This can be caused by a signal greater
than the split-core CT size or 277 V L-N, or by a signal with high THD near
the gain stage switching points (1.5 A and 10 A).
The main board has a flashing green light
• Everything is wired properly and the main board has power.
The main board is a flashing or solid red light
• Light may be red briefly while device powers up.
• If light is red for more the 60 sec. device has encountered a diagnostic
event. Contact technical support.
Split-core product is reading zero for some values
• Device was unable to read split-core adapter boards on power up. Verify
adapter boards are connected.
• Verify ribbon cable connectors are inserted in the correct orientation.
• Reset main board to re-initialize product.
Power factor reading is not as expected
• Verify voltage taps are connected in appropriate phase rotation.
• Verify phase rotation of breakers (firmware rev. 1.012 or higher allows for
custom rotation if needed).
Current reading is not as expected, or reading is on different CT
number than expected
• Verify ribbon cable is fully seated and in the correct orientation.
Current is reading zero, even when small currents are still
flowing through circuit
• The product cuts off at 50 mA, and will set the reporting register to 0 mA
for currents near or below this range.
E3x Config Tool returns Modbus error on read/write
• Verify use of the latest release of E3x configuration tool as older versions
may not support all features in current product firmware. Latest version is
available on the Veris website at www.veris.com/modbus.
