PowerMonitor 500 Unit 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 various three-phase, single-phase (2-wire European), and split-phase (3-wire North American single phase) circuits. The unit modular housing can be mounted in a panel that provides IP65 degree protection from the front. The power monitor can be provided with analog or digital (relay) outputs. These outputs can be selected to output a pulse proportional to the real and reactive energy that is measured, or to annunciate alarms. The instrument can also be equipped with a serial RS-485/RS-232 port or an EtherNet/IP port.
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 - report actual energy cost by department or process to integrate energy information into management decisions
Billing and sub billing - charge 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

Chapter 1 PowerMonitor 500 Unit Overview

PowerMonitor 500 Features and Functions

The power monitor connects to your three-phase, split-phase (3-wire North American single phase), or single-phase (2-wire European) 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: 120/208V or 400/600V
An optional pair of digital (relay) outputs
An optional pair of 0…20 mA analog outputs
Optional serial RS-232/RS-485 communication supporting Modbus

These diagrams are simplified. Wiring of the power monitor must comply with all applicable codes, standards, and regulations. Protect voltage and control power wiring with 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 affects the accuracy of the measurements.

Supply Power

Connect the PowerMonitor™ 500 unit to a source of supply power through user­provided disconnecting means, such as a switch or circuit breaker close to the power monitor. Provide overcurrent protection that is sized to protect the wiring. Apply supply power only after all wiring connections are made to the unit.

Additional devices that are provided with RS-485 are connected in parallel. The termination of the serial output is implemented only on the last instrument of the network, with a jumper between (B+) and (T). The jumper applies an internal termination resistance between (A-) and (B+). The RS-232 and RS-485 communication ports cannot be connected and used simultaneously.

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.
See the programming flowchart that begins on page 28 organization of programming menus and submenus. Each page is identified with a number, which is displayed in the top right corner. Menu page numbers end in zero, while submenu 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 submenu pages, and another way when you are editing a menu page.

1 Programming mode indicator Indicates programming mode.
2 Programming menu page Identifies the current programming menu page. See the programming flowchart that begins on page 28
3 Editing mode indicator Does not appear. Indicates the parameter being edited.
4 Cursor Does not appear. Appears beneath the digit currently being edited.
5 Permitted range Displays the permitted range of values for the selected parameter.
6 Exit button When in a menu page, exits Programming mode
without saving changes. Program/select button confirms exit.
When in a submenu page, exits to menu page.
7 Up button Selects the next higher-numbered menu or
submenu page.
Down button Selects the next lower-numbered menu of submenu
page.
8 Program/select button Press and hold for 2 seconds to enter the Program
mode.
Selects a menu page for editing.
When in a menu page with submenus, displays
the first submenu page.
After pressing the Exit button, confirms exit from Programming mode without saving changes.
From End menu page 260, saves new configuration and exits Programming mode.
Moves the cursor one digit to the left.
When the leftmost digit is selected, dP is
indicated and you can change the decimal point and multiplier (see Edit Decimal Point and
Multiplier on page 27).
When held for at least 2 seconds, cancels the edit and restores the previous value of the selected parameter.
Increments the value of the digit indicated by the cursor.
When dP is indicated, increments the decimal point and multiplier.
Decrements the value of the digit indicated by the cursor.
When dP is indicated, decrements the decimal point and multiplier.
Stores the new value of the selected parameter, but does not save the new configuration to the power monitor.

IMPORTANT
TIP
To save programming changes, navigate to the End menu page 260 and press Program/select. To exit the Programming mode without saving any changes, press Exit and confirm by pressing Program/select. If no buttons have been pressed for 2 minutes, the power monitor exits Programming mode without saving any changes.
You can make programming changes by using the PowerMonitor 500 software.

Edit 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.

10
To modify the decimal point position and the multiplier, use the Up and Down arrow (7) to select the desired value.
