Power & Energy Logger Model PEL 102 and PEL 103
For multiple-phase measurements, start by marking the accessories using the color-coded ID markers supplied with the
device; a different color for each current terminal.
Connect the measuring leads to your PEL as follows:
■ Current measurement: I1, I2, I3 4-point connectors
■ Voltage measurement: V1, V2, V3 and N terminals
The measuring leads must be connected to the circuit to be monitored according to the selected hook-up diagram. Do not
forget to dene the voltage and current transformer’s ratios when necessary.
2.5 Installation of the Color-coded ID Markers
Refer to the current sensor’s safety sheet or user manual before connecting it.
Twelve sets of color-coded rings and inserts are supplied with your PEL instrument. Use these ID markers to identify the
leads and input terminals.
■ Detach the appropriate inserts from the color-coded marker and place them in the holes provided under the
terminals (larger inserts for current terminals, smaller inserts for voltage terminals).
■ Clip the rings of the same color to the ends of the lead you will be connecting to the terminal.

2.11 Memory Capacity
The PEL accepts FAT32 formatted SDHC cards up to 32 GB in size. This much data can require a lot of demand on
a computer and a long download time (depending on the performance of the PC and connection type being used).
Furthermore, some computers may have problems handling such a large amount of data and spreadsheets can only
accept a limited amount of data.
Recording rates for the different types of session data are as follows:
■ 1s Harmonics: 83 MB per day.
■ 1s Trends: 17 MB per day.
■ Aggregated data: 1.2 MB per day for 1 minute periods.
For longer periods, this rate is divided by the period in minutes.
Example: for an aggregation period of 10 minutes, the rate will be 0.12 MB per day.
We recommend managing the data on the SD card and only recording that which is needed. For reference purposes,
a 5 day recording, with a 15 minute demand interval and recording 1 second data and harmonics on a 3-phase 4-wire
network would consume approximately 530 MB of storage space. If harmonics are not needed and the recording of them
is disabled, the space requirement is reduced to about 87 MB.
The recommended maximum recording times are:
■ seven days when the recording includes the aggregated values, 1-second data, and harmonics.
■ one month when the recording includes the aggregated values and 1-second data but not the harmonics.
■ one year when the recording contains only the aggregated values.
Also avoid exceeding 32 recorded sessions on the SD card.
NOTE: For recordings with harmonics or with a duration longer than one week, please use class 4 or higher SDHC cards.
We recommend not downloading large sessions through Bluetooth as it will take a very long time. If a Bluetooth download
is required, consider not recording 1 second trends and harmonics. The same 30 day recording would be reduced to just
2.5 MB.
Downloading over USB and Ethernet may be acceptable depending on the session size and network speed. We recommend putting the SD card into your PC directly or with the external card reader for fastest download time.

battery.
■ When the power is on, the battery is charging until it is full.
■ LED OFF: Battery full (with or without power supply).
■ Yellow LED ON/No blinks: Battery is charging.
■ Yellow LED blinks twice per second: Battery is recovering after a full
discharge.
■ Red LED blinks twice per second: Low battery (and no power supply).
Figure 9
After prolonged storage, the battery may be completely discharged. If so, the LED blinks twice per second. In
this case, at least 5 charge/discharge cycles will be necessary for your battery to recover 95% of its capacity.
3.2 Operating the PEL
IMPORTANT: The following OPERATION instructions assume that the PEL has been configured by the user prior to
use. The PEL can only be fully configured through the PEL Control Panel distributed with the DataView® software,
although on the PEL 103 some parameters (such as hookup type) can also be set through the LCD display on the
device itself. Please refer to § 4.3 for setup instructions using DataView®, and § 3.7.6 for setup through the PEL 103
LCD display.
■ The PEL must be first programmed before recording. This is done through the PEL Control Panel (see § 4.3) or, for
the PEL 103, this can also be done on the LCD display (see § 3.7.6).
■ The PEL is then connected to a power supply and will turn on automatically (see § 3.3.1).
■ Recording is started by pressing the Control button
■ The PEL can be turned OFF when disconnected from the power supply (and when the recording session is
completed - see § 3.3.2).
(see § 3.4).

Power & Energy Logger Model PEL 102 and PEL 103
3.3 Turning the Instrument ON/OFF
3.3.1 Turning the PEL ON
To turn the PEL ON:
■ Connect the PEL to a power outlet with the AC power cord and the PEL will turn ON automatically. If it does not,
press the ON/OFF button for >2 seconds.
■ The GREEN LED under the ON/OFF button turns ON when the PEL is connected to a live supply source.
NOTE: The batteries automatically begin recharging when the PEL is connected to a live power outlet. Battery life
is limited to approximately 1/2 hour when the battery is completely charged. This enables ride through during brief
power outages and power shutdowns.
3.3.2 Turning the PEL OFF
The PEL will not turn OFF as long as it is connected to a power supply source and if a recording is ON.
NOTE: This is done as a precaution to ensure that the PEL is not accidently turned OFF when recording and to ensure that
the PEL turns on when the power supply is turned back on after an outage.
To turn the PEL OFF:
■ Unplug the AC power supply outlet.
■ Press the ON/OFF button for more than 2 seconds until all LEDs turn on. Then release the ON/OFF button.
■ All LEDs and the display will turn off as the PEL powers down.
■ If the PEL has supply power present it will not turn OFF.
■ If a recording is pending or in progress it will not turn OFF.
NOTE: Pressing the ON/OFF button when the instrument is powered and/or recording (or pending) does not stop
the instrument. This is done to avoid any accidental or unintentional recording stoppage by the user. You must first
unplug the power cord from the supply outlet, stop any recording session, power down by pushing the ON/OFF
button for more than 2 seconds until all LEDs light up and then release the ON/OFF button.

3.4 Starting/Stopping a Recording and Enabling Bluetooth
Recordings are stored only on the SD card.
To Start a Recording:
■ Insert the SD-card into the PEL.
■ Use the Control button
■ Press the Control button for more than 2 seconds and hold it down.
■ The green REC LED (see #1 Figure 8) will light up for 3 seconds, followed by the lighting of the blue Bluetooth
LED (see #2 Figure 8) for 3s - one after another. During the time these LEDs are lit, you will be able to control their
respective function as described below.
■ Releasing the Control button during (and only during) the 3 seconds lighting of a particular LED performs the
associated function:
■ REC LED (START/STOP)
- A release while LED is lit starts a recording (if recording is OFF)
- A release while LED is lit stops a recording (if recording is ON)
■ BLUETOOTH LED (ON/OFF)
- A release while LED is lit turns ON Bluetooth (if Bluetooth is OFF)
- A release while LED is lit turns OFF Bluetooth (if Bluetooth is ON)
If you want to make changes to both the Recording and Bluetooth, you need to go through the process twice.
to start or stop a recording session and to enable or disable Bluetooth.
NOTE: If the Control button is locked (disabled) by the PEL Control Panel (see § 4), you cannot use it to start
or stop a recording, or enable/disable Bluetooth. Instead, upon pressing the Control button while it is locked
you will see the Bluetooth and REC lights blink twice, with no changes taking effect on the instrument. To enable
the Control button, you must open the PEL Control Panel on your PC and de-select the “Lock out the Control
button…” option in the Configure Instrument dialog box, as explained in the PEL Control Panel online Help.
3.5 Connections
3.5.1 Power Supply
The PEL is powered by standard AC power through an external C7 cord (gure-eight type, non-polarized power plug).
This power cord is available in many computer or electrical supply stores. It is also referred to as a Laptop or Netbook C7
power cable. For replacement, be sure to buy the non-polarized cord. Replacement power cords are also available from
the factory.
The PEL can be supplied from nominal 110V to 250V (accepts ±10%) 50/60Hz to accommodate available supply voltages
globally.
NOTE: Never use power cords with inadequate rating.
■ When the instrument is powered by AC power, the instrument is always ON.
■ Applying AC power to the PEL turns the instrument ON if it was OFF and starts recharging the batteries
automatically.
■ When AC power is not present (power supply OFF or disconnected from a power supply), the instrument will run
on battery power for approximately 30 minutes or less when Auto Power Off is enabled (see below).
■ The PEL has a built in Auto Power OFF, which can be set to 3 to 15 min or disabled.
■ When the battery level is too low and a Low Bat condition occurs (the red LED blinks twice per second), the
instrument will eventually turn OFF. The PEL will start up again once it has been reconnected to a power supply.
18
Power & Energy Logger Model PEL 102 and PEL 103
■ When the instrument is not powered by AC power, it can be turned ON with the ON/OFF button (see § 3.3.1).
■ When the instrument is not powered by AC power and no recording is pending or in progress, it can be turned
OFF with the ON/OFF button (see § 3.3.2).
3.5.2 Standby Mode (and Display Brightness)
When the instrument is ON and there is no activity for a denite time period, the LCD (PEL 103) automatically goes into
Standby mode.
The measurements and recording stay active, but the LCD backlight brightness diminishes to a user preset level. The
Standby LCD brightness level is user programmed through the PEL Control Panel (see § 4.4.1).
To re-establish the LCD Brightness, press the Enter or Navigation buttons.
Note that the overall display brightness is also programmed through the PEL Control Panel (see § 4.4.1).
3.5.3 Memory Card (SD-Card)
The PEL 102 and PEL 103 use an SD card for data storage. SD-Cards (up to 2 GB) and SDHC-Cards (4 GB up to 32 GB)
formatted FAT32 are supported. The PEL is delivered with a formatted SD card in the instrument. If you want to install a
new SD card, you must format the card before use.
■ Formatting the SD-Card is possible through the PEL DataView Control Panel when connected to the instrument
and if no recording is pending or in progress.
■ Hot extraction from the PEL is possible when no recording is in progress.
■ PEL les use short names (8 characters), such as Ses00004.
3.5.4 USB Connection to the PEL
The PEL 102 and PEL 103 can be connected to a computer through a USB (type A/Type B connectors) to congure the
PEL, prepare a recording session (real-time connection) and download recording sessions.
NOTE: Connecting the USB between the PC and the PEL will not power the logger or recharge the batteries.
3.5.5 LAN Ethernet Connection to the PEL
A LAN connection can be used to view real-time data, instrument status, congure the PEL, setup and start a recording
session and download recorded sessions.
The PEL has an IP address. When configuring the PEL with the PEL Control Panel, if the checkbox next to “Enable DHCP”
is checked in the Communication tab of the Configure Instrument dialog box (see § 4.4.2), the instrument sends a request
to the network DHCP server to automatically obtain an IP address.
If for any reason the DHCP server is not available, after 60 seconds the PEL Control Panel will enter auto-IP mode, using
the default IP address 169.254.0.100 (the same IP address used when “Enable DHCP” is not selected). This auto-IP mode
is compatible with APIPA (Automatic Private IP Addressing). A cross-over cable may be needed in auto-IP mode.
The Internet Protocol used is UDP. Port 3041 is used by default, but it can be modified in the PEL Control Panel (see §
4.4.2) to allow multiple PC connections to multiple PEL instruments behind a router.
NOTE: The LAN parameters cannot be modified while connected over a LAN link. A USB connection must
be used to modify them.

3.5.6 Bluetooth Connection to the PEL
The PEL 102 and PEL 103 are designed for a Bluetooth wireless connection to a computer. The Bluetooth connection can
be used to configure the PEL, to prepare a recording session and to download recorded sessions.
To communicate using the Bluetooth connection you will need a computer with Bluetooth capability. Some computers are
supplied with this capability, while others will need to have an external Bluetooth adapter.
The pairing procedure varies depending on your operating system, Bluetooth equipment and driver software.
The default pairing code is 0000 if needed. The pairing code cannot be modified through the PEL Control Panel (DataView®
software).
NOTE: The information in the following section is only necessary the first time an instrument is connected.
3.5.6.1 Pairing using Windows 7
The following example uses the Windows 7 operating system procedure. The pairing procedure for older versions of Win-
dows may vary.
1. First, make sure Bluetooth is enabled on the instrument (see § 4.4.2)
2. Connect the USB adapter to the PC.
3. A Bluetooth symbol, similar to this
, will appear in the taskbar (bottom-right side of your computer screen) once the
driver is installed.
4. Double-click on the icon and select “Add a Device”.
5. In the “Add a Device” window, select the PEL model you wish to connect to and select “Next”.
