The Power & Energy Logger Model PEL 52 is an easy-to-use, single-phase, and split-phase Power and Energy Logger. The instrument has a large, backlit LCD display for crisp viewing and an SD card to store measurements. Designed to operate in 600 V CAT III or lower environments. The PEL records voltage, current, power, and energy on alternating current distribution networks (50 Hz or 60 Hz). The instrument is compact enough to fit into many different distribution panels, has a water and shock resistant housing, operates on phase 1 input, and has a backup battery that charges from the V1 input during measurements. The following measurements and calculations can be made:
Phase-to-neutral and phase-to-phase voltage measurements up to 600 V
Current measurements up to 25,000 A, current sensor dependent
Automatic recognition of the different types of current sensors Frequency measurements
Measurements of active power P (W), fundamental reactive power Q (var), and apparent power S (VA) power
Measurements of fundamental active power Pf (W), non-active power N (var), and distorting power D (var) using the PEL Control Panel
Measurements of active energy at source and load (W·h), reactive energy on 4 quadrants (varh), and apparent energy (VAh)
Total energy meter
Calculation of cos and power factor (PF) Phase angle measurement
Calculation of aggregations of values from 1 minute to 1 hour
In addition to the types of measurements, the PEL 52 offers the following features:

3.1.1 Turning On

Connect the PEL to Network between the V1 and N, and it will turn on automatically. Otherwise, press and hold the ON/OFF button until the device turns on. If the instrument displays LOCK, the selection button is locked. The PEL Control Panel must be used to unlock the instrument (see § 5).
The battery will charge automatically when the PEL is connected to a voltage source between the V1 and N terminals. Battery life is approximately one hour when fully charged. This allows the device to continue operating during brief power cuts.

3.1.2 Auto Off
By default, the device operates in continuous mode, which is indicated by the symbol.
When the device is running on battery power, you can choose to have it turn off automatically after a period with no keyboard activity and no recording in progress to save battery life. This time will be defined in the PEL Control Panel (see § 5).

3.1.3 Turning Off
You cannot turn the PEL off while it is connected to a power source or while a recording is in progress or pending. This is a precaution intended to prevent a recording from being unintentionally stopped by the user.
To turn the PEL off: Disconnect the PEL.
Press and hold the ON/OFF button until the device turns off.

To begin installation: 1. Insert the DataView® thumb drive into an available USB port on your
computer. If Autorun is enabled, an AutoPlay window appears on your screen. Click Open folder to view files to display the DataView® folder. If Autorun is not enabled or allowed, use Windows Explorer to locate and open the USB drive labeled DataView. 2. When the DataView® folder is open, find the Setup.exe file located in
the root directory of the USB drive, and double-click the file to run the installation program. 3. The DataView® setup screen appears.

In the upper left corner of the screen, choose the language version of the Setup interface. (All Setup screens and dialogs will immediately appear in the selected language.)
In the lower left corner are the available installation options. In addition to the DataView® software, you can select Adobe Reader. This links to the Adobe web site where you can download the latest version of Reader. This program is recommended to view DataView.pdf documents.
The option, Firmware Upgrades, links to the website where you can check for new firmware updates for the PEL.
Finally, the option, User Manuals, displays a list of .pdf files contained in the USB drive that accompanies DataView®. (DataView® also comes with a Help system that is installed with the program files.)
To install DataView®, select DataView in the Options list and click Install.

Each AEMC® Instruments product family has their own specially designed Control Panel. If you perform a Complete install, by default all available Control Panels are selected (a check mark next to the Control Panel indicates it is selected). Control Panels take up disk space on the computer; so unless you have other types of AEMC® instruments, we recommend that you select Power Energy Logger (PEL) only and deselect all other instruments. You should also check the option DataView Core, which is a requirement if you plan to create DataView® reports.
After you finish selecting and deselecting Control Panels and/or DataView Core, click Next.

In general, core DataView® features are for creating, viewing, editing, and storing DataView® reports; while the PEL Control Panel is for connecting to, configuring, viewing measurements on, and downloading data from the instrument.
You can access all DataView® features through either the DataView® icon or the Control Panel icon. For users who interact with PEL 100 series instruments, we recommend primarily using the PEL Control Panel. However, there are situations where using the core DataView® icon may be more convenient for some users, such as when viewing multiple archived reports from different AEMC® Instruments product families.

7. MAINTENANCE

NOTE: Except for the batteries, the device does not contain any parts that can be replaced by untrained or unaccredited personnel. Any unauthorized work or part replacement with equivalents may seriously compromise safety.

7.1 CLEANING
WARNING! Risk of electric shock. Before cleaning, disconnect all inputs.

The instrument should be cleaned periodically to keep the LCD clear and prevent the buildup of dirt and grease around the instrument’s buttons and keys. Clean the body of the instrument with a damp and soapy cloth. Do not submerge the instrument in water. Do not use solvents.

For current sensors:
Ensure that no foreign body interferes with the current sensor latching mechanism.
Keep the air gaps of the clamp completely clean. Do not spray water directly on the clamps.

7.2 BATTERY
The device is equipped with a NiMH battery. This technology has several advantages:
Long battery life for a limited volume and weight;
Significantly reduced memory effect, which means you can charge the battery even if it is not completely discharged;
Environmentally friendly with no polluting material, such as lead or cadmium, in accordance with applicable regulations.
The battery may be completely discharged after prolonged storage. If the battery is completely discharged, it must be fully charged. The device may not work during part of the charging. Charging a completely discharged battery may take several hours.

NOTE: If the battery is completely discharged, at least 5 charge/ discharge cycles will be necessary for the battery to regain 95 % of capacity. Refer to the battery data sheet delivered with the device.

To optimize the use of your battery and extend the battery effective life: Charge the device only at temperatures between (50 and 104) °F (10 and 40) °C. Comply with the conditions for use. Comply with the conditions for storage.
