Flashing Display Notifications
The Voltage displays will flash when a voltage
is out of range.
Ÿ
In Mode A, the X, Y, or Z to Neutral voltage
display will flash when the voltage is below
108 Volts or above 131 Volts.
Ÿ
In Mode B, a voltage display will flash when
the voltage is less than 187 Volts or greater
than 228 Volts.
Theory of operation: Voltage Measurement:
The first 3 of 4 Voltage displays are the primary voltage
measurements. Normal use is expected to be 3 phase “Y”
with three 120 Volt AC Legs or single phase with two hot
Legs. It also measures Leg to Leg voltages of 208 Volts
AC. Maximum voltage Leg to Neutral or Leg to Leg is 280
Volts AC.
The PL-PM1 also measures Neutral to Ground voltages
th
(4 display, normal mode). The range on the Neutral to
Ground is 0 to 99 Volts AC.
Accuracy is better than 2%, typically 1%.
The Voltage Input connector is a Wago 5 pin model with
the center pin (safety ground) designed to mate first, due
to a longer pin.
The connections are (Left to Right looking at the rear of
the chassis)
1. X- Leg
2. Y-Leg
3. Safety Ground (extended pin)
4. Z- Leg
5. Neutral
Current Measurement:
Current measurement utilizes 4 Current Transformers part
# TRCT600:1. The PL-PM1 presents a 1.5 Ohm resistive
load to the current transformer. It has a 600 to 1 current
ratio. At 400 Amps AC in, the coil delivers 0.66 Amps AC.
The maximum current the PL-PM1 measures is 400 Amps
AC.
Accuracy is better than 2%, typically 1%.
The Current Input connector is an 8 pin Wago to the PL-
PM1 from the current transformers.
The connections are:
1,2:
X-Leg current loop
3,4:
Y Leg current loop
5,6:
Z-Leg current loop
7,8:
Neutral Leg current Loop
Polarity of the current loop inputs does not matter,
although it is recommended to connect the red and black
in a consistent fashion on all the coils.

Changing the PL-PM1RJ IP address
There are two methods of accessing the PL-PM1RJ to change the IP address.
1) Use a router to establish a small temporary network at 192.168.1.1.
2) Use a cross wired cable or two straight cables with a switch to directly connect a computer to the meter's
network connection jack.
Using a Router to set IP address
With the computer connected to the router, access the setup for the router.
Set the router to have an IP address 0f 192.168.1.1 and subnet mask of 255.255.255.0.
Connect the PL-PM1RJ to the router.
Type the IP address
into a browser on the computer to connect to the meter. Note that the PL-
http://192.168.1.200
PM1RJ also responds to ping commands.
When the browser window with the meter display opens, click on the Setup button in the lower right corner. To change
the IP address, simply type the new IP address and Subnet Mask in the boxes, check for accuracy, and click Apply.
The unit can also be given an identifying name in this screen as well. Once set internally, the system will try to contact
the unit at the new address.
To confirm the IP address, press and hold the mode button for more than 3 seconds, and, the IP address will appear
in the top row of LED number displays and the subnet mask will appear in the lower row of numbers. Press the mode
button again to exit this mode.
Note that for subsequent IP changes you must connect to the meter using its current address and the router must be
set correspondingly. The router IP right set of digits should always be lower than the computer and the meter settings.
Using a cross wired cable or Ethernet switch to change IP address
Using a cross wired Ethernet cable, connect a computer to the PL-PM1RJ. Using a web browser, type the IP address
PL-PM1RJ into address bar of the browser. The default address for the meter is 192.168.1.200. Allow time for the
computer to find the unit and open it in the browser window. This method also applies to using a switch with two
standard Ethernet cables to connect to the PL-PM1RJ.
When the browser window with the meter display opens, click on the Setup button in the lower right corner. To change
the IP address, simply type the new IP address and Subnet Mask in the boxes, check for accuracy, and click Apply.
The unit can also be given an identifying name in this screen as well. Once set internally, the system will try to contact
the unit at the new address.

Personalizing Display Features
The PL-PM1RJ has a Display
Parameters menu that allows for
display color changes and the setting
of alerts to indicate out of range
voltage readings. The meter reading
refresh rate can also be changed on
this screen. These settings are
stored as cookies in the web
browser, so they are specific to the
individual computers accessing the
PL-PM1RJ.
