PowerMonitor 5000 Unit Overview

ATT EN TI ON : Only qualified personnel, following accepted safety procedures,

can install, wire, and service the PowerMonitor 5000 unit and its associated components. Before beginning any work, disconnect all sources of power and verify that they are de-energized and locked out. Failure to follow these instructions can result in personal injury or death, property damage, or economic loss.

ATT EN TI ON : Never open a current transformer (CT) secondary circuit with primary current applied. Wiring between the CTs and the PowerMonitor 5000 unit must include a shorting terminal block in the CT secondary circuit. Shorting the secondary with primary current present allows other connections to be removed if needed. An open CT secondary with primary current applied produces a hazardous voltage, which can lead to personal injury, death, property damage, or economic loss.

Product Description

The PowerMonitor 5000 unit is not designed for nor intended for use as a circuit protective device. Do not use this equipment in place of a motor overload relay or circuit protective relay.

The PowerMonitor 5000 unit is the next generation of high-end electric metering products from Rockwell Automation. This new family of meters provides advanced technology, new functionality, faster response, and superior accuracy. The M5 model is the base version and provides an extensive range of metering functionality. The M6 model expands the metering capabilities of the M5 with basic power quality monitoring functionality, including harmonics up to the 63rd, waveforms and logging, and classification of power quality events. The PowerMonitor 5000 unit communicates power and energy parameters to

controllers, HMI software, and applications such as FactoryTalk software over the Ethernet network or other optional networks. The PowerMonitor 5000 unit works with controllers or software applications to address key customer applications including the following:

• Load profiling – logging power parameters such as real power, apparent power and demand, for analysis of power usage by loads over time

(3) 2 PTs used in open-delta configuration.

Voltage Sensing

Circuits rated up to 690V AC line-to-line can be connected directly. Higher voltages require potential transformers (PTs), also known as voltage transformers (VTs), to step the voltage down.

Wiring must conform to all applicable codes and standards. In particular, suitable overcurrent protection must be provided by the user, with current and interrupting ratings selected to protect the wiring.

Pay particular attention to correct phasing and polarity of voltage connections. The diagrams use the ‘dot’ convention to indicate transformer polarity. The dot indicates the H1 and X1 terminals on the high side and low side of the transformer respectively.

When wiring a PowerMonitor 5000 unit to existing PTs and metering devices, the voltage sensing terminals of the PowerMonitor 5000 unit must be connected in parallel with the voltage sensing terminals of the existing metering devices.

IMPORTANT

To s horti ng te rmin al bl ock and current transformer (CT).

Current Sensing

Route the CT secondary wiring through the openings in the PowerMonitor 5000 unit as shown.

Use a shorting terminal block (included in the 1400-PM-ACC accessory kit), test block, or shorting switch (by user) for CT wiring to permit safely servicing connected equipment such as the PowerMonitor 5000 unit without deenergizing the power system.

Use 2.5 mm PowerMonitor 5000 unit and the shorting block. Use 2.5 mm

(14 AWG) or 3.3 mm2 (12 AWG) (maximum) wiring between the

(14 AWG) or larger wire between the shorting block and the CTs, depending on the length of the circuit. Longer circuits require larger wire so that the wiring burden does not exceed the CT burden rating and reduce system accuracy. Note that the diameter of the current sensing wiring openings is 7 mm (0.27 in.).

Ring lugs are recommended for making CT secondary connections. Standard ring lugs do not pass through the current sensing openings of the PowerMonitor 5000 unit. We recommend that the installer pass the wire from the shorting terminal block through the current sensing opening before crimping on ring lugs.

When wiring a PowerMonitor 5000 unit to existing CTs and metering devices, current sensing circuits of the PowerMonitor 5000 unit must be wired in series with the CT secondary and current sensing circuits of the existing metering devices.

Do not install overcurrent protection or non-shorting disconnecting means in CT secondary wiring. Connect the current sensing circuit to a low-impedance earth ground at only one point.

Setup Chapter 3

EXAMPLE

This Metering_Basic page illustrates the setup for a 480V, 3-phase system with 1000:5 current transformer (CT) ratios on all phases and the neutral.

Native Ethernet Communication Setup

Choose the Configuration folder and choose the CommunicationsNative page. The PowerMonitor 5000 unit is set up by default to obtain an IP address automatically from a DHCP (Dynamic Host Configuration Protocol) server. If your power monitor is on a network served by a DHCP server, and the power monitor is connected to the network, it has probably already been assigned an IP address.

We recommend that each power monitor be assigned a static, or fixed, IP address, because DHCP addresses can change from time to time, resulting in loss of communication with client applications. Obtain a fixed IP address, subnet mask, default gateway, and other network setup parameters from your network administrator. Another option can be to set up the power monitor as a reserved client in the DHCP server.

Refer to Communication setup parameters.

on page 181 for more information on communication

Rockwell Automation Publication 1426-UM001F-EN-P - November 2013 45

Chapter 3 Setup

EXAMPLE

IMPORTANT

This example explains how to change from a DHCP-assigned to a static IP address.

The initial network configuration is shown below. The IP address assigned is 192.168.200.8. The network administrator has provided a range of static IP addresses in the same subnet, beginning with

192.168.200.100. In this case, the default gateway and DNS servers remain the same for static or DHCPobtained addresses (verify if this is true in your case with your network administrator).

To change to the new address, from the IP_Address_Obtain pull-down menu choose Static, type in the new IP address, and click Apply Changes.

You can change the network configuration from the USB or network web pages. If you change the IP address from the network Web interface, you need to browse to the new IP address to re-establish communication.

This section describes the functions of the PowerMonitor 5000 unit. Most functions require you to configure set-up parameters to align the unit with your installation and your application requirements. The set-up parameters are listed by name and described in this section. You can view set-up parameters by using the PowerMonitor 5000 web page, and when logged in to an Admin account, make changes to the setup. Set-up parameters are also accessible by using communication.

Basic Metering

Please refer to the Data Tables for additional information on setup parameters including the following:

• Range of valid values

• Default values

• Data type

Set-up parameters can be found in data tables with names beginning with ‘Configuration’, for instance Configuration.Metering_Basic.

The PowerMonitor 5000 unit calculates metering results based on the values of a number of set-up parameters. These basic metering parameters are listed in the table that follows. The basic metering setup is necessary to obtain accurate, properly scaled metering results.

This applies to all models of the PowerMonitor 5000 unit.

Rockwell Automation Publication 1426-UM001F-EN-P - November 2013 51

Chapter 4 Metering

Set-up Parameters

The following set-up parameters specify the configuration of the voltage and current sensing circuit, how the metered values are scaled, nominal values, update rate, and averaging. These parameters are found in the power monitor's Configuration > Metering_Basic web page.

Metering_Mode

Metering_Mode must match the external electrical system and how it is wired to the PowerMonitor voltage and current input terminals. Refer to the wiring diagrams in Chapter 2

0 = Demo 1 = Split-phase 2 = Wye (default) 3 = Delta, 2 CT 4 = Delta, 3 CT 5 = Open Delta, 2 CT 6 = Open Delta, 3 CT 7 = Delta, Grounded B Phase, 2 CT 8 = Delta, Grounded B Phase, 3 CT 9 = Delta, High Leg

. The following are the selections for the Metering_Mode:

V1_V2_V3_PT_Primary V1_V2_V3_PT_Secondary VN_PT_Primary VN_PT_Secondary

These parameters define the transformation ratios of the potential (voltage) transformers (PTs or VTs) used to connect the power monitor to the measured power circuit. When the power monitor is directly connected to the measured circuit (up to 690V L-L), you can specify any 1:1 ratio.

I1_I2_I3_CT_Primary I1_I2_I3_CT_Secondary I4_CT_Primary

These parameters define the transformation ratios of the current transformers (CTs) used to connect the power monitor to the measured power circuit. The secondary value is permitted to be only 5 A.

Nominal_System_LL_Voltage Nominal_System_Frequency

These parameters specify the nominal system (line-to-line) voltage and frequency. The power monitor uses these values to optimize metering accuracy, and the M6 model uses these values to set thresholds for detection of power quality events.

52 Rockwell Automation Publication 1426-UM001F-EN-P - November 2013

Metering Chapter 4

Realtime_Update_Rate

This parameter specifies the averaging used and the update rate of metering results to the data tables and setpoint calculations. You can select from the following:

0 = Single cycle averaged over 8 cycles 1 = Single cycle averaged over 4 cycles 2 = 1 cycle with no averaging

Wiring Diagnostics

The PowerMonitor 5000 unit provides a means for you to verify proper power monitor connections and diagnose wiring errors. To meter power and energ y correctly, voltage and current inputs must be connected to the power circuit with the correct phase rotation and polarity. Indications of wiring errors include the following:

• Indication of negative real power (kW) on a load, or indication of positive power on a generator

• Power factor outside the range of 45% lagging to 80% leading

• Very different power and/or power factor values on different phases

Wiring diagnostics operate on command in any wiring mode, and require a level of measured current at least 5% of the nominal metering scale, or 250 mA of CT secondary current.

The PowerMonitor 5000 unit calculates phase angles of voltage and current, and checks these against three distinct ranges of system power factor:

• Range 1: lagging 97% to leading 89%. This range is for very high lagging or significantly leading power factors. Examples of loads in this range include data centers, over-excited synchronous motors, and circuits with power factor correction.

• Range 2: lagging 85% to leading 98%. This range includes most industrial circuits that range from lagging to slightly leading power factors, including circuits feeding AC variable-frequency drives.

• Range 3: lagging 52% to lagging 95%. This range exhibits lower lagging power factors. Examples include lightly-loaded motor circuits and DC SCR drives.

Rockwell Automation Publication 1426-UM001F-EN-P - November 2013 53

Chapter 4 Metering

The power monitor displays wiring diagnostic status results for all three power factor ranges when a command is issued. You decide which power factor range applies based upon your knowledge of the circuit and its load characteristics. You can expect more reliable wiring diagnostic results when the circuit is operating in a normal condition, that is, not especially lightly loaded.

Figure 21

ranges show the I1 phase angle limits for each range. The phasor diagram shows the fundamental voltage and currents in a three-phase, 4-wire system operating with a lagging power factor of roughly 85%. In this example, ranges 2 and 3 wiring diagnostic can return good results, but range 1 can incorrectly indicate that all currents are inverted and displaced by a phase, as shown by the –I1, -I2 and –I3 phasors.

Figure 21 - Power Factors and Wiring Diagnostics

In addition to wiring diagnostics on command, the PowerMonitor 5000 unit updates voltage and current magnitude and phase angle data continually. These values are used by FactoryTalk EnergyMetrix RT software to display a system phasor diagram.

Semantics

Magnitudes are the scaled RMS value of the voltage or current. In Wye and splitphase modes, voltages are reported as line-to-neutral. In Delta modes, voltage is reported as line-to-line. Phase angles are referenced to Phase 1 Voltage, which is defined as zero, consistent with the 4-quadrant metering diagram included in

Power Metering

Note that current angles in Delta modes include a 30° offset due to the phase angle difference between Wye and Delta modes as shown in the following diagram.
