E31E Series

Split-Core Panelboard Monitoring System

Product Overview

The E31E Series panelboard monitoring system is designed to measure the current, voltage, and energy consumption of up to 92 circuits (84 branch circuits, 2 3-phase mains, 2 neutrals), enabling users to monitor two panelboards or an entire data center PDU with a single product. It increases the board’s current monitoring capability by combining the functions of two boards into one device.

The E31E consists of a data acquisition module, up to four current sensor adapter boards, and up to 84 split-core branch current sensors (50A, 100A, or 200A), with eight auxiliary inputs. Each conductor passes through the appropriate branch current sensor before terminating at the breaker. Each sensor transmits the current data to the data acquisition board. The E31E measures both current and power for the mains and branch circuits. The E31E can easily accommodate dierent panel congurations, including any combination of multi-phase breaker positions, voltage phase mapping, and breaker sizes. To congure the E31E for operation, download the E3x Conguration Tool and the E3x Commissioning Guide from www.veris.com.

Data is transmitted via ethernet with Modbus TCP, BACnet IP or SNMP protocol, or via RS-485 with Modbus RTU or BACnet MS/TP protocols. Some protocols can be used simultaneously, and the ethernet protocols all support access by multiple masters. Each data acquisition board requires two Modbus addresses, one for each set of 42 current sensors, and four auxiliary inputs. Data is updated roughly every two seconds. When a circuit exceeds the userdened thresholds, the E31E activates the alarm indicators. The communication interfaces and protocols require some conguration at the time of installation.

Installation Guide Power Monitoring EESeries

Data Outputs

The E31E provides several types of measurements that give a comprehensive view of power consumption for every monitored load on the panel:

• Real-time measurements: a live and up-to-date view of present power levels and the factors that aect them.

• Demand measurements: averages of values measured over a specied time interval. The time interval (typically 15

minutes) can be set from 10 seconds to more than a day. The demand calculation can be congured 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 specic 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 oset, 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 congured 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 specic thresholds. Latching alarms become active when the current exceeds the threshold for a time period greater than the specied 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 notications. Via SNMP, alarms drive SNMP event notications.

Advanced Features - The E31E supports a number of of advanced features. Some are always active, and others are congured manually via Modbus register 62017, BACnet object AV164, or SNMP MIB variable “spanels/panel1/p1Conguration/p1Setup/ p1UserDenedSettings” (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 congured independently for each panel.

• Logical Circuit support: The E31E can be congured to map any set of 1, 2 or 3 channels that are adjacent in the panel to 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 aects 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 E31E can be congured 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 older E3x models 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 E31E 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 inuenced by current phase changes vs. harmonic distortion. Phase angle measurements are instantaneous and always active.

• User CT phase assignment: In the default mode, the E31E 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 specication of the phase assignment for each channel. The explicit assignments set by the user are stored by the E31E in non-volatile memory.

• Phase angle reference: The E31E 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 specic current input channel.

Installation Guide Power Monitoring EESeries

Data Outputs (cont.)

• Signed power: Users can congure the E31E 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 fac tor: By default the E31E 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 E31E oers 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 specic date and time to synchronize the results with a larger system. The RTC must rst 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).
