7 2 Getting to Know the Portable Power Line Lab Figure 2-1 (PPLL top view) shows a top view of the PPLL. A detailed description of each of its components follows in the sections below. 2.1 PPLL Line Isolator Figure 2-1: PPLL top view The PPLL line isolator is shipped with your PPLL. You must connect it between the AC outlet and the PPLL. It is meant to protect from possible electrical hazards. 2.2 Power Supply Input Connector The power supply input connector receives power from the PPLL isolator. The power cord from the PPLL isolator is attached to the PPLL using a clip to prevent removing the PPLL isolator. The PPLL is protected against overload by a slow-blow fuse located in the power supply input connector. The replacement parts are listed in the following table. Page 7 of 30

8 Table 2-1: Fuse replacement parts PPLL Model Fuse Description Manufacturer Part Number Portable Power Line Lab 120 VAC (P/N: P-5-PPL ) 239 Series 5 x 20 mm Slo-Blo UL/CSA cartridge type fuse 4 A / 125 V / 5 x 20 mm / CSA / UL LITTELFUSE Portable Power Line Lab 240 VAC (P/N: P-5-PPL ) 218 Series 5 x 20 mm Slo-Blo cartridge type fuse 3.15 A / 250 V / 5 X 20 mm / UL & SEMKO LITTELFUSE Power Switch The power switch is used to power ON/OFF the PPLL. Setting it to I powers up the PPLL. The LEDs take approximately 5 seconds to light up on power up. 2.4 AC Outlets The PPLL has three pairs of outlets, identified respectively A, B and C. These outlets supply power to the power line devices and permit them to communicate over the medium. The 120 VAC model contains NEMA 15 AC outlets for North America. The 240 VAC model is reserved for the European market and contains continental Europe CEE 7 outlets. 2.5 Permanent Input Filter A permanent filter is located at the input of the PPLL. This filter serves two purposes: 1. Filter out noise from the grid. The filter provides an efficient filtering and insures the lowest noise level achievable on the outlets even if the attenuators are set to the lowest attenuation values. 2. Force a minimal 150-Ω (approx.) input impedance at 100 khz at the input of attenuator A. This constraint allows you to easily inject signals in the BNC input connector and obtain attenuation levels of -80 db and even more. The frequency response (see Figure 2-2: Frequency response of input filter) shows the efficiency of the permanent input filter. If a device with an output impedance lower than 150 Ω is to connected to the leftmost BNC connector, the performance of the input filter may be affected. Page 8 of 26

Page 9 of 30

10 Each attenuator is made of two components: Portable Power Line Lab User s Manual 1. A low-pass filter that attenuates all signals over 100 khz by at least 110 db. This filter allows the devices connected to the outlets to be supplied by the AC line. 2. An adjustable coupler that allows any signals in the 100 khz-400 khz range to bypass the low-pass filter. The PPLL has three adjustable attenuators, labeled Attenuator A, Attenuator B and Attenuator C in the figure above. Each attenuator can be controlled independently. Attenuator A is located between the filtered AC line and outlet pair A. Attenuator B is located between outlet pair A and outlet pair B. Attenuator C is located between outlet pair B and outlet pair C. Section 7 (Attenuator ) provides more details about the response of these attenuators Attenuator Status The current attenuation setting, for the 100 khz-400 khz range, can be read on the LED bar graph display shown in Figure 2-4 (LED bar graph display): Figure 2-4: LED bar graph display There is a 10-dB interval between each LED. When all LEDs of a bar are lit up, there is no attenuation for the corresponding attenuator. The maximum attenuation is reached when only the 100 db LED is lit up Attenuator Control The current attenuation setting can be controlled on the panel shown in Figure 2-5 (Attenuator control panel): Page 10 of 26

11 Figure 2-5: Attenuator control panel The desired attenuator is selected by pressing the SELECT button. The green LED corresponding to the selected attenuator is lit up. The arrow keys are used to increase or decrease the attenuation level by steps of 10 db. The up arrow decreases the attenuation, while the down arrow increases the attenuation. If no button is pressed for 30 seconds after the attenuation setting has been changed, the PPLL saves the current setting. The last saved setting is restored on power up Attenuators Combination / Coupling The attenuation between two non-consecutive sections is the sum of the two attenuators between these sections. For example, if attenuator B is set to 20 db and attenuator C is set to 60 db, the attenuation between pairs of outlets is the following: -20 db between pairs A and B -60 db between pairs B and C -80 db between pairs A and C However, undesired coupling may happen through internal wires and chassis of the PPLL and external devices connected to the PPLL outlets. Therefore, the actual sum may not exceed -110 db. As an example, -80 db on attenuator B and -80 db on attenuator C may result in an attenuation of -110 db between pairs A and C. Tips to Reduce Undesired Coupling Between Devices The devices should be kept away from each other; Each device should be placed on an isolated plate (wood, glass, etc.); The device s power cords should be kept away from each other; For plug-in devices, it is recommended to use an extension cord for each device to ensure that devices are not too close from each other. Page 11 of 30

12 2.6.4 Effects of Impedance on the Attenuators For the LED bar graph display to accurately reflect the actual attenuations, the devices connected into the outlets must have an output impedance of 75 Ω or higher in the 100 khz-400 khz range. If devices with lower impedance are connected into the outlets, the attenuation reading may be erroneous. In this case, the user can measure a frequency response between the input and the output using a device such as a spectrum analyzer or an oscilloscope connected to BNC connectors - see section 2.7 (BNC Connectors). A cross-reference between the actual values and those displayed on the LED bar graph display can then be established Ground Path Communication The PPLL is designed to provide attenuation between phase and neutral paths only. The ground path cannot be considered for power line communication due to the UL regulations. Note that a current leak can occur over the ground and potentially reduce the efficiency of the attenuator circuits, especially for high attenuation settings. The attenuator circuits cannot be used for testing power line devices that communicate or leak current over the ground. 2.7 BNC Connectors Description The PPLL system has four BNC connectors allowing to monitor or add signal between each stage of attenuators. Refer to Figure 2-3 (Attenuators interconnections) to identify the connectors points of insertion. These connectors can be used to both monitor and add signal to the line. They are isolated from the power line: when monitoring, the AC signal is already filtered out. When adding signal to the line, the PPLL properly couples the signal to the power line. Thus, a standard device such as a waveform generator or a scope can be directly plugged into any of the BNC connectors Restrictions on Using the BNC Connectors Monitoring instruments (scope, spectrum analyzer, etc.) should have input impedance greater or equal to 75 Ω. If the impedance is adjustable, it is recommended to set it to 1-MΩ. If a device is used to add signal via a BNC connector, its input impedance should be at least 75 Ω. Signals added to the power line via BNC connectors must not have amplitude greater than 3 V peak in the khz range. The input impedance of the BNC connector is 27 Ω and may affect the injected signal s amplitude depending on the output impedance of the signal source. 2.8 RS-232 Serial Port The RS-232 serial port is used to read and control the attenuation settings RS-232 Connector Figure 2-6 (RS-232 ) shows the location of the pins on the RS-232 connector. Page 12 of 26

13 Figure 2-6: RS-232 outline The connector is a standard female DB-9. The serial port s baud rate is 9600 baud. Note: There must be at least a 15 ms delay between primitives sent to the PPLL.

14 3 Installation of the Portable Power Line Lab 3.1 Portable Power Line Lab s Line Isolator The PPLL line isolator is shipped with your PPLL. You must connect it between the AC outlet and the PPLL. It is meant to protect from possible electrical hazards. Installation of the line isolator is straightforward. 1. Turn the PPLL OFF. 2. Connect the free connector from the PPLL (male twist-lock inlet) to the isolator female twist-lock outlet. 3. Connect the isolator male power connector to the grid. 4. Power the PPLL ON. Figure 3-1: Interconnecting the line isolator with the PPLL 3.2 Permanent Installation The PPLL complies with IEC third Ed Part 1: Panels and racks standard and can be mounted into a 19-inch rack mount frame using the two brackets provided with the PPLL. It is necessary to screw the rack mount brackets on each side of the PPLL before installing the PPLL on a rack mount. Remove the PPLL from its plastic case by pulling the two metal handles and refer to Figure 5-1 (Portable Power Line Lab mechanical specification) to screw the brackets correctly. 3.3 Field Installation The PPLL comes with a handy portable plastic case that allows you to easily carry it in the field. To safely operate the PPLL, remove the PPLL from its plastic case by pulling the two metal handles, and install it on a dry and stable surface. Page 14 of 26

15 4 How to Use the Portable Power Line Lab System You must carefully read chapter 1 (Introduction) before operating the PPLL. 4.1 Powering up the PPLL To power up the PPLL 1. Make sure that the PPLL is installed properly (refer to section 3, Installation of the Portable Power Line Lab). 2. Set the power switch to I. a) The LEDs take about 5 seconds to light up. b) The LED bar graph display indicates the last selected attenuation settings. 4.2 Changing the Attenuation Settings To change the attenuation settings 1. Press the SELECT button to select the attenuator. 2. Press the arrow buttons to modify the attenuation value. a) The up arrow increases the signal strength (reduces the attenuation). b) The down arrow decreases the signal strength (increases the attenuation). c) The LEDs on the bar graph show the corresponding signal strength or attenuation value for each attenuator. When all LEDs are on, it indicates that the maximum strength signal is going through the corresponding attenuator. 4.3 Measuring the Signal at the PPLL AC Outlets To measure signal strength at PPLL AC outlets - Connect the external measurement equipment on the corresponding BNC connector. 4.4 Generating Noise at the PPLL AC Outlets To generate noise at PPLL AC outlets - Inject noise signal using proper noise generator equipment through the corresponding BNC connector, and/or - Connect a noisy device on the corresponding PPLL AC outlet. You must make sure that the maximum input voltage to the BNC connector or the total maximum load of all connected devices do not exceed the limit specified in section 5.1 (Electrical Specifications). 4.5 Reading Attenuation Settings with a RS-232 Interface To read the attenuation settings - Send the following primitive to the PPLL: FF FF FF <Attenuator ID> <Checksum> Page 15 of 30

16 The PPL responds with the following confirm message: FF FF FF 80 <Attenuator ID> 01 <Attenuation Value> <Checksum> 4.6 Changing Attenuation Settings with a RS-232 To read the attenuation settings - Send the following primitive to the PPLL: FF FF FF <Attenuator ID> 01 <Attenuation Value> <Checksum> The PPL responds with the following confirm message: FF FF FF 80 <Checksum> The table below shows the meaning of the parameters in brackets.

21 6 Troubleshooting For this equipment to perform as expected, a solid ground is required and wiring must be clean. 6.1 About the Ground The PPLL s power cord must be connected to earth. The PPLL s power cord must be plugged directly into a wall outlet. This outlet must have 3 prongs. 2-prong plugs must not be added to the PPLL s plug section. It does not isolate, it impedes on the attenuator s performance. 6.2 About Wiring For attenuations above 70 db, pay a special attention to cables. Two power cords crossing can have enough inductance to mislead you in your tests. Be also careful with static mats that also are slightly conductive. Keep power cords away from the mats. If you want to isolate PowerBus or other messages circulating on the power line, simply set the attenuation on section A to 90 db and you will not need anymore filtering. In some rare cases RS-232 cables are enough to generate coupling through the signal ground. In case of doubt, disconnect the cable. 6.3 Troubleshooting Table The following table contains procedures for troubleshooting common problems that may occur with the PowerBus Portable Power Line Lab. Because a single symptom may be the result of any one of many possible causes, causes and solutions are listed in order, from most likely to least likely. If after attempting all the solutions below, the problem persists, you may contact Domosys technical support team by either phone or on regular eastern time business hours from 8:30 a.m. to 5:00 p.m. at: Domosys Corporation 585 Charest blvd E, 7th floor Québec City, Quebec Canada G1K 3J2 Tel: (418) Fax: (418) support@domosys.com Problem The PPLL LEDs do not light up when the switch is ON. The signal passes through the attenuators even with the maximum attenuation settings. Action Verify all connections. Verify the PPLL fuse. See section 2.2 (Power Supply Input Connector).

23 7 Attenuator Characterization 7.1 Units of Measure The attenuated signal is displayed in db units on the PPLL. It is computed using the following formula: Attenuation (db) = 20 log (Vout / Vin) Where Vout is the resulting signal at the output of the attenuator and Vin is the input signal. Table 7-1 (db Units and signal ratio) shows the computed attenuation in db unit for a corresponding signal ratio. Table 7-1: db Units and signal ratio db Vout/Vin 0 1/1-10 1/ / / / / / / / / / Frequency Response This section shows the attenuators frequency response in a few example situations. Figure 7-1 (-20 db between A and B) shows the frequency response between outlet pairs A and B when attenuator B is set to 20 db, and other attenuators set to 0 db. Page 23 of 30

24 Figure 7-1: -20 db between A and B The three following figures show measurements that have all been taken with the following attenuation settings: -60 db for attenuator B and 40 db for attenuator C. Figure 7-2 (-60 db between A and B) shows the measurement taken between outlet pairs A and B. Figure 7-2: -60 db between A and B Figure 7-3 (-40 db between B and C) shows the measurement taken between outlet pairs A and B. Page 24 of 26

25 Figure 7-3: -40 db between B and C Figure 7-4 (-100 db between A and C) shows the measurement taken between outlet pairs A and C, which is the sum of both attenuations (-60 db db = -100 db). Figure 7-4: -100 db between A and C Figure 7-5 (-140 db between A and C) shows the measurement between outlet pairs A and C for the following setting: -80 db for attenuator B and -60 db for attenuator C. In this case, the total attenuation should be -140 db, but it does not exceed -110 db. See section (Attenuators Combination / Coupling) for details. Page 25 of 30
