Introduction

Note: The CE mark indicates RoHS2 compliance. Please refer to the CE Declaration of Conformity for additional details.

The PowerLogic™ BCPMSCE Series panelboard monitoring system is designed to measure the current, voltage, and energy consumption of up to 92 circuits (84 branch circuits, two 3-phase mains, two neutrals), enabling users to monitor two panelboards or an entire data center PDU with a single product. It also includes Ethernet capability, allowing communication in multiple protocols.

The BCPMSCE consists of a data acquisition module, up to 4 current sensor adapter boards and up to 84 split-core current sensors (50 A, 100 A, or 200 A), with eight auxiliary inputs. Each conductor passes through the appropriate current sensor before terminating at the breaker. Each sensor transmits the current data to the data acquisition board. The BCPMSCE measures both current and power for the mains and branch circuits. The BCPMSCE can easily

accommodate different panel congurations, including any combination of

multi-phase breaker positions, voltage phase mapping, and breaker sizes. To

congure the BCPMSCE for operation, use the Schneider Electric ION Setup conguration software tool. Get the latest version at

https://schneider-electric.box.com/ionsetuplatest.

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.

When a circuit exceeds the user-dened thresholds, the BCPMSCE activates

the event indicators. The communication interfaces and protocols require some

conguration at the time of installation.

Data Output

The BCPMSCE 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 affect 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 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 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.

• Over-threshold Events (previously referred to as 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 events. Events are reported as both non-latched events and latched events. Non-latching events are active while the current exceeds the threshold, but go inactive if the current

Branch Circuit Power Meter with Ethernet Communication Introduction

Z206857-0C

04/2020

returns to a level within the specic thresholds. Latching events

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. Event status can be polled via any protocol. Via

BACnet, Subscribe_COV can be used to generate event notications. Via SNMP, they drive SNMP event notications.

Advanced Features - The BCPMSCE supports a number of advanced features.

Some are always active, and others are congured manually via Modbus

panel1/p1Conguration/p1Setup/p1UserDenedSettings” (OID .1.3.6.1

.4.1.3833.1.30.1.1.6.3.4.0). For models with 42 channels or more, these

features are congured independently for each panel.

• Logical meter support: The BCPMSCE can be congured 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

BCPMSCE 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

BCPMSCE models with a rmware 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 BCPMSCE 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 BCPMSCE 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 self-assignment 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 BCPMSCE in non-volatile memory.

• Phase angle reference: The BCPMSCE 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.

• Signed power: Users can congure the BCPMSCE 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)

Z206857-0C 04/2020

Branch Circuit Power Meter with Ethernet Communication

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 BCPMSCE 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 BCPMSCE 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 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).

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

Installation

The protective ground connection on the housing should be used if the device will not be mounted to a suitably grounded surface. Assure conductivity to the protective ground.

1. Determine where you will mount the BCMPSCE measurement unit.

The preferred location is inside the enclosure of the panelboard being

monitored. If sufcient space is not available there, then mount the unit

in an appropriate enclosure nearby. Decide whether to mount it vertically or horizontally. The meter is shipped with the brackets placed for vertical mounting. If desired, you can move the brackets from the sides to the ends of the housing. Loosen the screws on the sides of the BCPMSCE that hold the brackets in place (do not fully remove the screws from the housing). Loosen the screws on the two ends of the housing (do not fully remove the screws from the housing), and set the brackets into their new positions. Tighten all screws to 25 in-lb (2.8 N-m).

Figure 5 Brackets positioned for vertical and horizontal mounting

Vertical Mounting Horizontal Mounting

2. Install the BCPMSCE in the panel. A grounding connection is located on

the housing (see below).

Figure 6 BCPMSCE ground stud

Ground

3. Choose a location to mount the adapter boards. If space permits, mount

them in the panelbord being monitored. There are two channel numbering

congurations available, for different applications (see the examples below).

Odd/even numbering is used with panelboards that have odd numbers on one side (usually the left side) and even numbers on the other. Sequential numbering is generally used in other applications, where the panelboard has breakers numbered sequentially or where the branch circuits are used to monitor discrete loads rather than an entire panelboard. Select the

conguration that best ts your application and install the adapter boards

as close as you can to the location where the branch CTs will be installed. Mount the adapter boards using either DIN rail or SNAPTRACK. You can

set the conguration during commissioning by writing to Modbus Register 6

Branch Circuit Power Meter with Ethernet Communication Installation

Z206857-0C

04/2020

(or the corresponding BACnet object or SNMP variable) or use ION Setup

conguration software.

A. Use the supplied screws to secure the plastic DIN clips to the adapter

board. Afx the clip to the DIN rail.

Figure 7 DIN mount configuration options

DIN Option 1: Vertical Mount

DIN Option 2: Horizontal Mount

B. Secure the SNAPTRACK to the mounting surface. Click the adapter board into place.

Figure 8 SNAPTRACK mounting

4. Install the current sensors onto the conductors to be monitored.

NOTE: If the signed power factor feature is NOT enabled, then the current sensor orientation does not affect meter behavior. If this feature IS enabled, orient the current sensors so that the arrow points toward the load for proper operation.

NOTE: Clean split-core contact surfaces before closing. The hinge can detach, allowing the base and the top to separate for easier cleaning and installation.
