PowerMonitor 500 Overview

Chapter 1

About the PowerMonitor 500 Unit

The PowerMonitor 500 unit is an AC power monitor with a built-in advanced configuration system and LCD data display. The unit is designed for measurement of electrical parameters in a variety of three-phase and single-phase circuits. The unit is enclosed in a modular housing for panel mounting, with IP65 degree of protection in front of the panel. The power monitor can be provided with analog or digital outputs. These outputs can be selected to output a pulse proportional to the real and reactive energy measured, or to annunciate alarms. The instrument can also be equipped with a serial RS-485/RS-232 port, or an EtherNet/IP port, and analog outputs.

Equipped with an optional communication port, the unit communicates power and energy parameters to applications, such as FactoryTalk® EnergyMetrix™ software. The power monitor works with these software applications to address these key customer applications:

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

• Cost allocation - reporting actual energy cost by department or process to integrate energy information into management decisions

• Billing and sub-billing - charging users of energy the actual usage cost rather than allocating by square footage or other arbitrary methods

• Power system monitoring and control - display and control power flow and energy utilization

PowerMonitor 500 Features and Functions

The power monitor connects to the user's three-phase or single-phase AC power system directly or through instrument transformers (PTs and CTs). It converts instantaneous voltage and current values to digital values, and uses the resulting digital values in calculations of voltage, current, power, energy, and demand.

The power monitor family includes several models that combine the following basic components:

• A panel-mounted power monitor in one of two AC voltage ranges: 240 (208Y/120V) or 690Y/400V

• An optional pair of relay outputs

• An optional pair of 0…20 mA analog outputs

• Optional serial RS-232/RS-485 communication supporting Modbus

RTU

• Optional Ethernet port supporting EtherNet/IP and Modbus TCP

• Front protection degree: IP65, NEMA 4X, NEMA 12

Wiring Diagrams

The wiring diagrams in this manual are drawn with European (IEC) conventions. For convenience, a connection diagram is shown below in IEC style on the left and in its corresponding NEMA style (used in the U.S.) on the right.

Figure 7 - Wiring Diagram Interpretation

These diagrams are simplified. Wiring of the power monitor must comply with all applicable codes, standards, and regulations. Voltage and control power wiring must be protected by suitable overcurrent protection. Connect current transformer (CT) secondary wiring through a suitable shorting terminal block.

In these diagrams, ‘balanced load’ configurations permit 3-phase measurement by using only one phase connection. Unbalance in the measured circuit impacts the accuracy of the measurements.

Unit Configuration

Chapter 3

Configure with the Display

The PowerMonitor 500 unit provides menu-based configuration (programming) by using its front panel display. The programming menus let you select parameters to edit, select digits within parameters, and increase or decrease the value of each digit.

Place the unit in Programming mode by pressing Program/select (8) for about 2 seconds. The front panel displays the PASSWORD? menu page 0 in Editing mode. Enter the correct password by using the Up and Down arrows (the default password is 0) and press Program/select. The front panel then displays the CHANGE PAS menu page 10.

Refer to the programming flow chart beginning on page 26 organization of programming menus and sub-menus. Each page is identified with a number. Menu page numbers end in zero, while sub-menu pages end in 1 through 9. For example, the Change Password page is menu 10. Likewise, the Dmd page is menu 80, and the demand interval Time page is menu 82.

While you are programming the power monitor, the display items and control buttons function one way when you are navigating between menu or sub-menu pages, and another way when you are editing a menu page.

Chapter 3 Unit Configuration

Digital Filtering Operation

Digital filtering smooths out the display of fluctuating values. The parameter FILTER S defines the operating range of the filter. This operating range is represented as a yellow band (each small square is one digit). While the measured value (red curve in figure) is within this band, the filter is active. Once the value exceeds the operating range, the filter is deactivated and a new band is active around the new value. The range of fluctuation (in digits) is a good starting value for such parameters.

The parameter FILTER CO represents the filtering coefficient. The higher the FILTER CO, the smoother the curve of the displayed values (black in figure). There is not a theoretical rule to define this parameter, it is set in the field. One rule is to start with the value of the FILTER S coefficient and then increase FILTER CO until the desired stability is reached.

The digital filter affects the values retransmitted both via serial communication and analog output.

Digital Fluctuation

Digital Filter Programming Examples

These sections give digital filter programming examples.

Example 1

This example describes how to stabilize the displayed value of the VL-N variable, which fluctuates between 222V and 228V. The parameters of the digital filter have to be programmed as follows.

FILTER S: The variable fluctuates within the mean value whose amplitude is equal to ±0.75% of the full scale rated value of the variable itself (obtained by the following calculation: (228-222)/ 2= ±3V, then ±3*100/400V= ±0.75% where 400V is the phase-neutral rated value of a 1420-V2 unit input). The ‘range’ parameter, representing the action range of the digital filter, is to be programmed to a value that must be slightly higher than the percentage amplitude of the fluctuation, for example, 1.0%.

30 Rockwell Automation Publication 1420-UM001D-EN-P - September 2013

Unit Configuration Chapter 3

FILTER CO: if the new value measured by the instrument is within the action range of the filter, the new displayed value is obtained by adding algebraically the previous value to the variation divided by the filtering coefficient. As a consequence, a value higher than this coefficient implies a longer settling time and therefore a better stability. You generally obtain the best result by setting the filtering coefficient to a value equal to at least 10 times the range parameter value.

In the following example, 1.0*10=10, the stability of the filtering coefficient can be improved by increasing the filtering coefficient; the allowed values are included within 1 and 255.

Example 2

This example describes how to stabilize the value of the displayed System Real Power (W), which fluctuates between 300 kW and 320 kW. In this example, the load is connected to the instrument by means of a 300/5 A CT and a direct measure of the voltage.

The parameters of the digital filter must be programmed as follows.

FILTER S: the variable fluctuates within the mean value whose amplitude is equal to ±2.78% of the full scale rated value of this variable. This value is obtained by the following calculation: (320-300)/ 2= ±10 kW, then ±10*100/360 kW= ±2,78%, where 360 kW is the rated value of the System Real Power of an 1420-V2 unit input, at the above mentioned CT and VT ratios and obtained by means of the following formula:

VLN * VT * IN * CT * 3

Where:

VLN = rated input voltage (400V for the V1 input)

VT= primary/secondary ratio of the voltage transformer being used

IN = rated current (5 A)

CT = primary/secondary ratio of the voltage transformer being used (in this example 400*1*5*60*3=360 kW).

The RANGE parameter, representing the digital filtering coefficient action range, is to be programmed to a value that must be slightly higher than the percentage of the fluctuation: for example 3.0%.

Rockwell Automation Publication 1420-UM001D-EN-P - September 2013 31

Chapter 3 Unit Configuration

FILTER CO: if the new value acquired by the unit is within the filtering action range, the new displayed value is obtained by adding algebraically the previous value to the variation divided by the filtering coefficient. As a consequence, a value higher than this coefficient implies a higher settling time and therefore better stability. Generally speaking, the best result is obtained by setting the filtering coefficient to a value equal to at least 10 times the value of the range parameters. In the example, 3.0*10=30. To improve the stability, you can increase the filtering coefficient; the admitted values are included within 1 and 255.

Example 3

It is necessary to stabilize the value of the displayed variable AL 1 (phase current 1), which fluctuates in the range 470 A and 486 A.

To be able to manage the alarm function and activation and deactivation of the relay, this value is not to be subject to continuous fluctuations. In this example, we have considered using a 500/5 A CT. The parameters of the digital filter are to be programmed as follows.

FILTER S: the variable fluctuates within the mean value whose amplitude is equal to ±1.60% of the full scale rated value of this variable (obtained by means of the calculation: (486-470)/ 2= ±8 A, then ±8*100/500 A= ±1.60% where 500 A is the value referred to the primary of the transformer being used). The ‘range’ parameter, which represents the action range of the digital filter, is to be programmed to a value slightly higher than the percentage amplitude of the fluctuation, for example 2.0%.

FILTER CO: if the new value acquired by the instrument is within the filtering action range, the new displayed value is calculated algebraically adding to the previous value the variation divided by the filtering coefficient. As a consequence, a higher value of this coefficient implies a higher settling time and therefore a better stability. Generally speaking, the best result is obtained setting the filtering coefficient at a value equal to at least 10 times the value of the range parameter. In the example, 2.0*10=20. To improve the stability you can increase the filtering coefficient; the admitted values are within 1 and 255.

Analog Output Configuration Examples

These examples apply to units with catalog numbers 1420-V1A and 1420-V2A.

Example 1: Power value retransmission by means of a 0…20 mA analog output.

This example describes how to retransmit measured consumed power up to 100 kW by means of a 4…20 mA signal. Program the unit as follows:

• VAR IA BL E: W

• MIN OUT: 20.0% means 4 mA. The calculation to be carried out is the

following: (100*minimum output) / full scale output =100*4 mA/ 20 mA=20%

• MAX OUT: 100.0% means 20 mA. The calculation to be carried out is: (100*maximum output)/full scale output = 100*20 mA/20 mA= 100

• MIN INPUT: 0.0 k; the multiplier k, M, G can be selected on the unit according to the chosen VT and CT values

• MAX INPUT: 100.0 k; the k, M, G multipliers can be selected on the unit according to the selected VT and CT values

Example 2: Retransmission of the power factor (PF) value by means of the 0…20 mA analog output.

In this example, the unit is set up to retransmit the whole range of the allowed values for the PF with a signal from 0…20 mA. The value of the PF variable can vary between C0.001 and L0.000 (for each phase); these values, when retransmitted, correspond to 0 and 20 mA. When the PF value is equal to 1, the analog output value corresponds to the middle of the scale, that is 10 mA. Program the instrument as follows:

• VARIABLE: PF L1 (or L2 or L3 or PF

• MIN OUT: 0.0%

• MAX OUT: 100.0%

• MIN INPUT: C0.001 (the C symbol shows a CAPACITIVE value)

• MAX INPUT: L0.001 (the L symbol shows an INDUCTIVE value).

L0.001 has been chosen as minimum value to be set to avoid undesirable rapid changing of the outputs

The PowerMonitor 500 unit supports the following Modbus functions:

• 0x03 - Read n Holding Registers

• 0x04 - Read n Input Register

• 0x06 - Write one Holding Register

• 0x10 - Write multiple registers

• 0x08 - Diagnostic (with sub-function code 0x00)

• 0x42 - Read n Special Registers (vendor specific)

• Broadcast mode (write command on address 00h)

In this section, Modbus addresses are indicated in two ways. The ‘Modbus address’ is expressed as the 6-digit input register address (example: 300123), used with Modbus function code 0x04. The ‘Physical address’ is the hexadecimal representation of the word address that is to be included in the communication frame.

Modbus function 0x04 can be used with the Modbus address by substituting a 4 for the first digit (example: 400123). With that distinction, functions 0x03 and 0x04 return the same data.

To avoid errors due to signal reflections or line coupling, a termination resistor must be connected at the RS-485 ports of the master station and of the furthest power monitor from the master station. Termination on both ends is necessary even in case of point-to-point connection, with short distances.

The GND connection is optional if a shielded cable is used. For connections longer than 1000 m (3280 ft), a line amplifier is necessary.
