Introduction
The PM172 is a compact, multi-function, three-phase AC powermeter and power
quality analyzer specially designed to meet the requirements of users ranging
from electrical panel builders to substation operators.
If you are familiar with the PM172 Powermeter, use this quick start guide to
prepare the units for operation. If you are not familiar with the PM172, read the
Installation and Operation Manual carefully before installing and using the unit.
This quick start guide does not contain information on all the features of PM172.
See the Installation and Operation Manual for full operating details and features.

IMPORTANT!
Only qualified personnel can perform setup.
All incoming power sources must be turned off during installation. During operation of the
Powermeter, hazardous voltages are present on the input terminals. Failure to observe precautions
can result in serious or even fatal injury, or damage to equipment.
Refer to the installation and operation manual for further information.

Figure 7: Typical Installation 1
The typical installation diagram above shows a 4-Wire Wye 3-element connection
using 3 PTs and 3 CTs. The wiring mode is 4LL3 or 4Ln3.
Figure 8: Typical Installation 2

PM172 Quick Start Guide
Series PM172 Powermeters 7
The typical installation diagram above shows a 4-Wire Wye 2½-element
connection using 2 PTs and 3 CTs. The wiring mode is 3LL3 or 3Ln3. The voltages
must be balanced for the configuration to provide accurate power measurements.
There are approximately nine different wiring configurations in the PM17X Series.
Refer to the Installation and Operational Manual for additional configurations.
For electrical installation of the display panel follow the following steps:
1. Connect the remote display using the pinout tables below, either for a
self-powered display or a remote powered display. Refer to the
Installation and Operation Manual for the wiring schematic diagrams.

Using the Navigation Buttons
Figure 9: Navigation Buttons

PM172 Quick Start Guide
8 Series PM172 Powermeters
Setup is performed directly from the display panel or via the communication ports
using PAS communication software.
In Data Display mode, the navigation buttons function as follows.
The MIN/MAX button switches to the Min/Max Maximum Demands display pages.
When briefly pressed again, it switches back to the common measurements
display.
The TDD/THD/ESC button switches between different total harmonics
(THD/TDD) displays. Individual harmonic analysis is available in the PM172EH
model only. When briefly pressed once again, it switches back to the common
measurements display.
The UP and DOWN arrow buttons, labeled by arrowheads, scroll forwards and
backwards through the display pages. Pressed briefly, they move one page
forward or backward. If you hold the button down, the display pages are scrolled
at rate of a twice per second.
Pressing both the UP and DOWN arrow buttons together returns to the first page
within the current display.
The SELECT button operates once it’s released. The button has two functions:
o When pressed briefly, switches to programming mode.
o When pressed together with the ENTER button for more than
5 seconds, it resets Min/Max records, maximum demands, or
energies depending on the currently displayed page. If the
meter is password protected, and a simple reset of data from
the display is not allowed, the action has no effect.
The ENERGY/ENTER button switches to the Energy display. If TOU registers are
configured in the meter, you can repeatedly press this button to scroll through all
available TOU registers. When briefly pressed once again, it switches back to the
common measurements display. The energy measurements are not available in
the PM172P model. In this model the ENERGY/ENTER button is replaced by the
ENTER button.
Auto Return
If no buttons are pressed for 30 seconds while the display Auto Return option is
enabled, the display automatically returns to the main screen from any other
measurement display.
The Auto Return option is enabled through the Display Setup menu
Auto Scroll
If no buttons are pressed for 30 seconds while in the common measurements
display, and the Auto Scroll option is enabled in the meter, the display
automatically scrolls through all available pages. The scroll interval is adjustable in
the Display Setup menu.
To stop auto scrolling, briefly press the SCROLL button.

Basic Setup
Entering the Password
The setup change menu is secured by a four-digit user password. The meter is
primarily shipped with the password preset to 0, and password protection
disabled. You can change the password and enable password protection through
the Access Control menu.
If authorization is not required, just press the ENTER button to move to the Main
menu; otherwise enter a correct password to be authorized to access the meter
setup.
To enter the password:
1. Adjust the first digit with the UP and DOWN arrow buttons.
2. Press the SELECT button to advance to the next digit.
3. Adjust the remaining password digits in the same manner.
4. Press ENTER to confirm the password.
If the password entered is correct, you move to the Main menu, otherwise you
return to the previous menu.
Basic Configuration
Use the navigation buttons to set up the PM172 as required.
The table below shows the available options. The asterisk * shows the default
settings.
The basic menu allows you to configure the basic meter settings that define the
general operating characteristics of the device.
To enter the menu, select the “bASc” entry from the main menu, and then press
the ENTER button.
To select a setup option:
1. Press the SELECT button to activate the middle window.
2. Use the UP and DOWN arrow buttons to scroll to the desired option.
