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.

Unit Configuration Chapter 3

Editing Decimal Point and Multiplier

When the cursor is beneath the last digit on the left, pressing Exit (6) lets you change the decimal point and the multiplier (9) (k or M). The blinking ‘dP’ (decimal point) text (10) indicates this capability.

To modify the decimal point position and the multiplier, use the Up and Down arrow (7) to select the desired value.

Chapter 3 Unit Configuration

Configuration Flow Chart

• 10 CHANGE PAS: this function lets you modify the PASS value with a new value (from 0…9999).

• 20 BACKLIGHT: adjusts backlight time from 0…255 minutes (0 = always on).

• 50 SYSTEM: this function lets you select the type of electrical system.

Refer to pages 17 diagrams corresponding to the system type designations, such as, 3P and 3P.n.

• 60 CT RATIO: this function lets you select the value of the CT ratio (primary/secondary ratio of the current transformer being used). Example: if the CT primary (current transformer) has a current of 300 A and the secondary a current of 5 A, the CT ratio corresponds to 60 (300 divided by 5).

• 70 PT RATIO: this function lets you select the value of the PT (VT) ratio (primary/secondary ratio of the potential/voltage transformer being used). Example: if the primary of the connected PT is 20 kV and the secondary is 100V, then the PT ratio corresponds to 200 (20,000 divided by 100).
