About Panoramic Power^® and the Bridge 

The Panoramic Power System monitors electrical energy consumption at the site level as well as at the individual circuit level. It detects excess usage, allowing organizations to identify and reduce energy, maintenance expenses and monitor site level consumption. 

The system consists of wireless, self-powered sensors engineered to allow for rapid, non-invasive installation, with almost no disturbance to operations. Sensors are easily attached to circuit breakers by snapping them onto the outgoing electrical wire. They monitor the flow of electricity through the magnetic field it creates and also use it as a power source. The sensors do not require any maintenance.

Sensors report the power consumption to the Bridge. The Bridge in turn transfers the circuit level information, along with readings originated by the utility meter and read through a pulse input on the Bridge, to the solution's cloud–based analytics platform. A single Bridge can collect data from up to 250 sensors and two utility meters, and multiple Bridges can be used in a single site to increase coverage.

Four generations of Bridges were developed, with the fourth generation now available: 

Basic Entry Level Bridge (PAN-2-E-EWC-US/EU) 

Advanced Cellular Bridge (PAN-2-H-3G-US/EU), featuring a SIM card slot.

Gen 3 Bridge (PAN-2H-3G-US/EU V3), featuring a SIM card slot.

Gen 4 Bridge (PAN-2H-3G-US/EU V4), featuring a SIM card slot and two KY pulse inputs.

Gen 4+ LTE Bridge (PAN-2H-3G-US/EU V4+ (LTE)), featuring LTE SIM card slot, two KY pulse inputs and a Modbus RS-485 connector, or LAN Bridge (PAN-2H-US/EU V4+ (LAN)), which does not include a cellular module.

The table below lists the key features of each Bridge.

T

The Advanced 3^rd and 4^th Gen Bridge provide store-and-forward capability. In case of a network loss that impacts connectivity with the cloud-based server, the Bridge stores measurements until communication is restored.

The Bridge storage capacity is shown in the table below:

Pulse input data is stored for up to 30 days.

This guide explains how to install and configure the Advanced 4^th Gen Bridge. For information on previous generations of Bridges, see the corresponding installation and configuration guides.

Install the Bridge as explained in Mounting the Bridge.

Network Time Protocol (NTP) configuration

To operate properly, the Bridge requires accurate time-of-day information. After reset, the Bridge gets this information using the standard NTP protocol. This protocol is also used to periodically verify the accuracy of the internal clock.

By default, the Bridge uses a set of predefined publicly accessible NTP servers. In this mode, when using a corporate (Ethernet or Wi-Fi) network, a firewall rule allowing outbound NTP access is required.

Alternatively, a dedicated NTP server address can be specified. This mode is useful for deployments within corporate networks, when the NTP Bridge is internal. In this case, there is no need to open the NTP firewall port.

Import / Export Network Configuration

The ‘Network Setup’ tab contains two buttons for exporting and importing the network configuration (see highlighted in blue in the image above).  This can be used by installers of multiple Bridges with similar network configurations in the following way:

• Configure one Bridge with network parameters
• Export the configuration
• Edit the configurations where necessary (e.g. to add the Wi-Fi password which is not saved during export)
•  Import the configuration to other Bridges. 

Export: 

Export network configuration will allow you to save each of the network settings to a text file in INI format.

Note: Wi-Fi passwords will not be saved to the file. The format of the configuration file is covered in ‘Network export file structure’ on page 44.

Import: 

Import network configuration will allow you to upload each of the network settings from a text file in INI format.

Note: Wi-Fi passwords are not saved in the file and should be added manually before importing. 

Bridge Connection setup

The ‘Connection Setup’ tab, configures the main Bridge operating mode. Panoramic Power Bridges can have three operating modes:

• Connect to PowerRadar – This is the default mode in which all sensor data received is sent to the cloud for processing and display. This mode is used by customers who use the cloud-based server for data analytics and processing or those who use the platform’s cloud base export. 
• Stand Alone Mode (Modbus) – In this mode the Bridge processes and displays sensor readings locally. It makes these readings available in the Bridge UI and via Modbus TCP or RTU interface to be read by a Modbus master server.  This mode does not require cloud access and is used to integrate sensor data to local 3^rd party systems. 
• Dual mode - Both options above can be activated simultaneously allowing sensor data to be sent to the platform and processed locally at the same time.

How to Proceed

1. In the Connection Setup tab, apply the right checkbox based on the desired mode:

• Check Connect to PowerRadar to establish connection and send sensor data to the cloud.
• Check Enable stand-alone Modbus mode to enable processing of sensor data locally and to enable a local Modbus interface to be used to retrieve sensor data. Select either Modbus TCP or select Modbus RTU and provide the Base Address in the field (1 to 247).
• Check Enable remote firmware update to allow the server to periodically upgrade the Bridge firmware when a new version is available. This option is only supported when Connect to PowerRadar is checked. 

2. By default, the connection to the cloud-based server (if enabled) will be using TLS. To change the default connection URL or protocol, click Advanced Settings. 
3. To discard changes made to an unsaved configuration and return to the saved settings, select Cancel. Otherwise, to save the configuration to the Bridge, click Save and Reboot.

The Bridge will start uploading the file from the disk. The Bridge power LED will blink Red (the same as in USB or remote upgrade). At the end of the process, there will be a note on the screen and the Bridge will restart.

Resetting the Bridge Configuration to Factory Defaults

Important Restoring to factory defaults will erase all your Bridge data and settings and revert to Ethernet networking. 

How to Proceed 

1. Access the Bridge web interface.
2. Select Bridge Configuration.
3. Click Reset to factory default at the bottom of the page.
4. At the prompt, click OK.
5. The Bridge will reboot with factory setting. 
6. Follow the steps described in ‘Initial Bridge Configuration’ on page 12 to reconfigure the Bridge using config mode.

Starting with firmware V470, the Bridge can operate in stand-alone mode. In this mode, sensor data is stored and displayed on the Bridge itself and can be made available to an external Modbus server.

Enabling stand-alone mode

By default, the stand-alone mode is disabled, and the Sensors tab is also disabled. To enable the stand-alone mode: 

1. In the Connection setup tab, select the checkbox next to Enable stand-alone Modbus mode. 
2. This mode can work in conjunction to Connect to PowerRadar mode.
3. Select the Modbus connection type: Modbus TCP or Modbus RTU.
4. When selecting the Modbus RTU, enter the Base Address (1 to 247).
5. Set the RTU connection rate by selecting a port rate (bps) from the dropdown menu
6. Click Save and Reboot to make this change in the Bridge
7. When the Bridge reboots, the Sensors tab will become enabled and allow the configuration of sensors to process.

The Sensors tab

When working in stand-alone mode, the Bridge can store readings of up to 32 data points (A single phase sensor or a phase in a 3-phase sensor), display them in the Sensors tab and make them available via Modbus.

In stand-alone mode, each sensor (identified by its serial number) is assigned to a slot (a 3-phase sensor is assigned to 3 consecutive slots). Whenever the Bridge receives a reading from this sensor, it updates the slot readings and makes it available to be retrieved by Modbus. This way each sensor is always located in a specific location.

Assigning a sensor to a slot

1. In the Sensors tab, select the slot to which you want to assign the sensor.
2. + sign.

3. In the popup dialog choose the Type of sensor:

4. For other than PAN-42, Provide the serial number of the sensor to use and move to the Calibration Key field

5. Type the calibration key if you have it or click ‘Get Key’ to have it automatically retrieved and inserted (The web site must be reachable from the configuration laptop).
6. Click Save to populate the slot and close the pop-up window.

7. Type the sensor’s serial number. The sensor is registered in 3 slots (for 3 phases).
8. Press the Save button.

Note 1: Stand-alone mode supports the following sensor types: PAN-10, PAN-12, PAN-14 and up to 3 PAN-42 sensors.

Note 2: The calibration key is a unique, per-sensor, value used by the Bridge to calibrate each reading for accuracy. It is a mandatory, sensor specific, value.

Note 3: When clicking ‘Get Key, your browser communicates with the software to get the calibration key. It is, therefore, essential that the laptop has Internet connectivity.

Note 4: If having issues retrieving the calibration key, please contact support who can provide an offline list of calibration keys to be entered manually. 

9. Repeat this for as many slots as needed. 
10. Once complete, click Save Settings at the bottom of the tab to flush the updated table to the Bridge memory. 

Viewing sensor data

Once a sensor has been assigned to a slot, every sensor reading received by the Bridge will be displayed in the table.

The table will always show the latest reading received. A new reading will override the previous one.

Information displayed includes:

• Slot number
• Serial Number of the sensor assigned to this slot
• Sensor type
• Last reading timestamp as measured by the Bridge RTC clock
• Last Current reading in Ampere
• The reception level[2] of the recent message (RSSI) 

Scroll Right for additional readings:

Note 1: The information provided here is also available via the Modbus TCP/RTU interface. Please refer to the Bridge Programmers Guide for more information.

Note 2: The current readings shown here have already been individually calibrated by the Bridge for accuracy, using the calibration key.

Note 3: PAN-10 and PAN-12 current readings can be used as-is. For PAN-14, these values should be multiplied by the CT Rate of the CT used. 

For PAN-42, the table will show the following additional values:

• Voltage [V]: The last measurement in Volts RMS
• Active Power [W]: The last measurement in Watts
• Reactive Power [VAR]: The last measurement in VARs
• Power Factor: The last measurement power factor
• Frequency [Hz]: The last measurement in Hertz

Note 4: For PAN-42 the current, active power and reactive power reading values should be multiplied by the CT-Rate of the CT used.

Removing a sensor from a slot

It is possible to remove a sensor from a slot.

1. In the Sensors tab, select the slot you want to edit or clear.

2. You can delete a PAN-42 sensor by pressing the Trash-Can at any of the 3 sensor lines, all 3 lines will be deleted.

Once complete, click Save at the bottom of the tab to flush the updated table to the Bridge memory. 

Configuring the Pulse Inputs

If you connect the Bridge to a meter’s pulse output, you will need to enable the pulse inputs in the Bridge configuration.

Prerequisites

Have the pulse outputs connected to the pulse input connectors on the side of the Bridge.

How to Proceed

1. In the Pulse Setup tab, select the checkbox next to the pulse input you want to enable
2. The Bridge counts the pulses automatically. The counters update every 10 seconds.
3. When connected to the platform, the pulse count is sent to the platform automatically.
4. When Stand-alone (Modbus TCP/RTU) mode is enabled, the pulse reading is available via Modbus TCP/RTU.
5. Pulse inputs are of type KY (2 terminals) but the counter counts both the Rising and Falling edges of the pulses. If the connected device is of type KY, you need to divide the reported counter value by 2. If the connected device is of type KYZ, connect either the K and Y terminals or the K and Z terminals. You do not need to divide the reported counter value by 2.

Upgrading the Bridge Firmware 

This section explains how to upgrade the Bridge to the latest firmware version.

Upgrading using a USB stick

Prerequisites

Make sure you have a USB flash drive with the upgraded firmware, or a FAT-32 formatted USB flash drive if you need to download the firmware from your email account.

How to Proceed

1. Download the firmware to the root directory of the USB flash drive, if necessary.
2. Make sure the firmware file name is pan_gen.fw in the root directory of the USB flash drive. If the name is different, change it to pan_gen.fw.
3. Connect the USB flash drive to the USB port on the Bridge. The power LED will turn off for a short blink. This tells you that the Bridge recognized the USB flash drive.
4. e is not yet operational. 

Note If you proceed to the next Step before the self-test sequence ends, the Bridge enters configuration mode rather than upgrade mode.
 

5. If the Bridge is connected to the LAN network, disconnect it from the LAN network.
6. Press the Configuration button for approximately 20 seconds. After 5 seconds the LED Red turns on to show that you can enter to configuration mode (by releasing the button). Keep pressing the button and the Red LED will turn off. After approximately 20 seconds the LED will turn Orange (Red and Green). You can release the button.
7. The LED lights Orange. All other LEDs are off. The Bridge is in firmware upgrade mode.
8. Wait several minutes for the upgrade process to complete (up to 5 minutes). When the Bridge loads the file into the internal flash, the LED blinks fast in Orange. Then, the Bridge reboots, the blinks stop shortly and starts blinking Orange again while the firmware is installed into the controller.

After a successful upgrade the Bridge will reboot. TheLED lights green, and the Bridge returns to normal operation. A LED self-test sequence occurs, and the Bridge returns to normal operation.

9. Disconnect the USB flash drive.

Note 1: If the firmware file is missing, the Bridge will blink the Power LED and the LED in Red, three times, and stop the upgrade process.

Note 2: If the firmware version on the USB drive is identical to the one installed, the Bridge will blink the LED and the Link LED in Green, three times, and stop the upgrade process. The Bridge will not be updated, and the power LED will turn red. A lower version will result in downgrading the Bridge’s firmware and a reset of the Bridge configuration.

‘Over the air’ firmware upgrades

When connected to the cloud-based server, the Bridge can automatically receive firmware upgrades from the cloud. To enable this feature, go to the Connection Setup tab and check Enable remote firmware updates. 

Note 1 To complete the setup, please also enable firmware updates on the platform’s Bridge settings. Please refer to the software documentation for more information.

Note 2 Over the air firmware updates only work when the connection to the server is secure (over TLS port 443). It will not work is If the Bridge is set to TCP connectivity. 

Upgrade through the Configuration Tool UI

The user can upgrade the Firmware from the Bridge Configuration screen.

Pressing the “Upgrade Firmware File” button will open a file selection window to select a file from the local disk. Select the Firmware file (pan_gen_.......fw) and press the “Open” button.
The Bridge will start uploading the file from the disk. The Bridge LED will blink Red (the same as in USB or remote upgrade). At the end of the process, there will be a note on the screen and the Bridge will restart.

Troubleshooting & Diagnostics 

Hardware based ‘Revert to factory settings’ 

When reverting the Bridge to factory settings, all Bridge configuration is erased and returned to its factory default (including the Bridge admin credentials). This procedure can be done from the admin UI or using a special hardware interface sequence.

From the “Bridge Configuration” section of the Bridge Configuration Tool, click on the red “Reset bridge to factory settings” option under the Upgrade Firmware File option

When the Bridge admin interface cannot be accessed (due to unknown credentials or other reasons), it is possible to perform a hardware factory as described below: 

How to Proceed

1. Remove all connections or cables from the Bridge.
2. Connect the Bridge to the power source.
3. Press the Configuration button for approximately 5 seconds, until the LED lights solid red. The Bridge is now in configuration (Config) mode.
4. Press the Configuration button five (5) times at a rate of one press per second. 
5. The Bridge should now reboot with default factory settings
6. If the Bridge does not reboot, you may need to re-try steps 1 through 4 again a few times, until the Bridge reboots. 

The Diagnostics tab

The Diagnostics tab is where you can test the Wi-Fi or cellular connection while in config mode.  This Tab is only available when connected in Config mode

How to Proceed

1. Access the Bridge web interface as explained in Accessing the Bridge Web Interface via ‘Config Mode’ on page 10.
2. Select the Diagnostics Tab.
3. Click Verify server connection to make sure the Bridge communicates with the cloud-based server. 

Note: This method will work only for Wi-Fi and Cellular networking modes. It will not work in Ethernet mode, since in Config Mode the Bridge’s Ethernet cable is connected to the Configuration laptop.  

4. Click Ping to google.com to make sure the Internet connection is working. 

Bridge Console

The Bridge console is for Panoramic Power technician use only and should not be used by end customers unless directed by customer support.   

Troubleshooting

If you encounter a problem, try the solutions listed in this section. 

Otherwise, contact Customer Support for help by submitting a support ticket at https://www.powerradar.energy/support .

Problem

The Bridge is not receiving sensor data (theLED is off).

Solutions

Try moving the Bridge closer to the electrical panel. 

Verify the position of the sensors in the electrical panel: make sure they are visible or try moving them to the front of the panel.

Make sure the RF antenna is tightly screwed into the antenna connector of the Bridge.

Make sure the Bridge is not in configuration mode (theLED lights red).

Problem

The Bridge does not connect to the cloud-based server (the Link LED does not turn solid green).

Solutions

If you are using Ethernet:

Look at the LAN port (RJ-45 connector) on the Bridge. It contains two small built-in LEDs. One of them should light solid green and the other should be blinking orange. If this does not happen, tighten both ends of the LAN cable or replace it. 

If the Link LED blinks green but does not turn solid, it means that local network connectivity is established but the Bridge cannot access the cloud-based server. This is often caused by local firewalls blocking TCP port 8051. Please verify this with your system administrator.

If you are using Wi-Fi:

Verify the wireless network reception strength in the status page. The level should be at least two, preferably three (out of five). 

If no reception level is showing and “Connecting…” is shown instead, it means that the Bridge cannot establish Wi-Fi network connectivity. In this case, please verify your Wi-Fi credentials (SSID, Security Type or password). 

If the Link LED blinks green but does not turn solid, it means that local network connectivity is established but the Bridge cannot access the cloud-based server. This is often caused by local firewalls blocking TCP port 8051. You can verify this using the Diagnostics tool or with your system administrator.

If you are using cellular:

Verify the cellular network reception strength in the status page. The level should be at least three (out of five). 

If no reception level is showing and “Connecting…” is shown instead, it means that the Bridge cannot establish cellular network connectivity. In this case, please verify your cellular credentials (APN, PPP credentials where needed), and make sure the SIM card has a valid and enabled data plan.

You can test the cloud connectivity using the Diagnostics tool.

Problem

The Bridge does not connect to the cellular network when using the SIM card (Link LED is off).

Solutions

Make sure the SIM card is in place before connecting the Bridge to the power source.

After verifying that the SIM card is tightly secured in its slot, disconnect the Bridge from the power source and reconnect it.

Verify with your service provider that a data plan is enabled for your SIM card. The Bridge connects to the cellular data network only if the SIM card has a data plan.

In low reception areas it may take a while for the Bridge to connect. Enter configuration mode and check the reception bar in the Status page.

Problem

The Bridge does not return to normal operation after a firmware upgrade ( LED lights red).

Solution

The upgrade was unsuccessful, and the Bridge rolled back to the previous firmware version.

How to Proceed

1. Disconnect the USB flash drive from the Bridge.
2. Disconnect and reconnect the power cable to the Bridge.
3. The Bridge performs a self-test and the LED lights green. The Bridge is ready for normal operation with the rolled-back version.
4. Enter configuration mode and check the running firmware version in the Status page.
5. Contact Customer Support if you need additional assistance.

Bridge Log Extraction

In cases where we want to investigate issues in the Bridge, there is a debug log in the Bridge.

To extract the log, follow these steps:

1. Disconnect the PC from all communication (Bluetooth, Wi-Fi, etc.).
2. Connect the PC to the Bridge and enter configuration mode as explained in Accessing the Bridge Web Interface via ‘Config Mode’ on page 10. 
3. Open the command line in the console.
4. Type: ipconfig.
5. If the default gateway is 10.0.0.13, you can connect the computer to the Bridge. If not, type ipconfig /release.
6. After the operation is done, type: ipconfig/renew. Then type: telnet 10.0.0.10.

8. Click ‘d’ (lowercase only as this is case-sensitive).
9. The log history will be printed on the terminal until this row appears:
    

10. Copy the log by right-clicking on the CMD, and then Edit Select All, Ctrl C, and copy the information to a Notepad or Word file and send the file to Support via submitting a support ticket.,

Check if your network blocks connection to the cloud-based server

1. Take a laptop and connect it to the same network as the Bridge.
2. Open the cmd terminal and type: 

3. If you enter a black empty screen, this means you can reach this URL from this network.
4. If you do not enter a black empty screen and instead you see the message below, it means there is likely a problem in the firewall.

5. If step 4 occurs, connect the Bridge via a hotspot from your cellular device and see if the Bridge can connect. 
6. If step 5 was unsuccessful, the unit may have a hardware issue, please contact support. 
7. If step 5 was successful – talk to the local IT – the TLS connection is probably blocked or there could be a mismatch on the port: the Bridge is working on full duplex (configure as auto on both sides) of 100baseT.
8. If auto and auto still don’t work configure the switch’s port to be 100 full. 
9. Without a DNS server the Bridge will not be able to connect, so make sure there is an active DNS service on the network.
10. If public NTP port (123) is blocked by IT, you can supply an alternative local NTP server for the Bridge to use. 

Handling failed Firmware upgrades 

When upgrade was unsuccessful, the Bridge rolls back to the previous firmware version and stays in this mode. In this case the power LED lights red

1. Disconnect the USB flash drive from the Bridge.
2. Disconnect and reconnect the power cable to the Bridge.
3. The Bridge performs a self-test and the LED lights green. The Bridge is ready for normal operation with the rolled-back version.
4. Enter configuration mode and check the running firmware version in the Status page.
5. Contact Customer Support for further help.

 Network export file structure

The following image is an example of the INI file created when exporting the Bridge network configuration. The file contains five sections with key value pairs. 

Most values are self-explanatory strings, below are some values that are enumerations of possible options: 

Connection: 
1-Ethernet
2-Cellular
3-WIFI

wifiSecurity: 
0-no Security
1-WEP 64
2-WEP 128
3-WPA
4-WPA2
5-WPA Ent,
6-WPA Ent2

ipSettings: 
0-Automatically obtain IP address and DNS server
2-Use static IP address and DNS server
3-Automatically obtain IP address and use static DNS
4-Use static IP and obtain DNS server

ntpSettings:
0-Automatically connect to a public NTP server
1-Use specific NTP server

Problem

The Bridge is experiencing multiple reconnections when set to Wi-Fi connection type.

Solution

Run a Diagnostics command to determine the Wi-Fi signal strength of the Bridge.

How to Proceed

Connect laptop to the bridge and put it in Configuration Mode.  

Once the Bridge is configured for Wi-Fi, check the Status page to ensure the Bridge’s Wi-Fi network has at least 4 bars

If it is 3 bars or less, in the Diagnostics tab, run the following AT command in the Console field to check the RSSI signal strength:

• AT+WRSSI=?
• On screen it will be:

AT+WRSSI=?

-63

OK

RSSI (WIFI) >=-60dBm. 

NOTE: If during installation customer have 3 bars, it is good indication that in the future he might have WIFI disconnections.
