How to Detect the Fault? 

Fault Description 

Troubleshooting Steps 

No Power 

When the Fuel sensor is connected to the power source, it does not receive any power 

1. Check that incoming wires from the Power source are properly secured both at the connector harness and at the Galooli DB. 

1. Check if the cables have continuity at both ends. 

1. Make sure the power supply is 12 volts DC. 

No Communication 

When the Fuel sensor is connected to the communication Terminal block, it does not communicate with the Elara unit 

1. Check the cables have continuity at both ends. 

1. Make sure the power supply is 12 volts. 

1. Check termination of the RS485 communication is properly done. 

No communication  

The fuel sensor is receiving power, but the unit is not connected to Elara or K2 

Connect your serial converter to the ports for RS 485 B and pin 4 for RS485 A 

Read all configurations communication protocol  should be set at  

Device ID :15 

Baudrate :19200 

Open the Holykell configuration Tab Set Baudrate at 19200 

Id Scan the fuel sensor and if it lands on a different ID from 15. Click on next Icon and set the default ID and Baudrate as 15 and 19200 respectively.  

If no communication is present 

Open the Holykell configuration Tab Set Baudrate at 9600 

Id Scan the fuel sensor and if it lands on a different ID from 15. Click on next icon and set the default ID and Baudrate as 15 and 19200 respectively.  

The device is communicating but giving the wrong data 

The Fuel sensor should be taken out of the fuel tank and held straight on a flat surface. 

Ensure the tip of the fuel sensor is 2cm from the base of the fuel’s sensor securing rod 

Read all configurations from the Holykell fuel sensor calibration tab on the Services center. 

Once done perform the Zero calibration on the fuel sensor. 

Status 1 LED does not blink
or
You are unable to connect to the unit on the PC

1. First thing, Check the power source. Ensure the terminations of the power cable are correct and the breaker is switched ON.

1. If DC to DC converter is present, confirm that the DC-DC converter output voltage is within range (12v DC). If there is no output voltage from the DC-DC converter AND there is input to the converter, replace the DC-to-DC converter with a functional one.

1. Confirm (on Pin 1 & 2) that Elara is receiving the required input voltage from the power source (Normally around 12v DC). If not, check the cabling between the converter & the Elara.

1. Confirm that Elara PCBs are arranged properly & all the pins are aligned. Rearrange the PCBs if needed.

1. Make sure the power supply input has 48 volts of DC.

2. Ensure that the cable is properly connected on the Elara side.

1. Confirm that Elara PCBs are arranged properly & all the pins are aligned. Rearrange the PCBs if needed.

The status 2 LED is blinking rapidly red
or
Red error in the Power Center

Make sure that the SD card is properly inserted. Push the SD card to release and push it again to lock. if not still working, replace the SD card.

The status 2 LED is blinking slowly red
or
Red error in the Power Center

The SD card should be written with the correct files. Always recommended to delete all existing files & recopy new Elara files to the SD card.

COM LED is blinking red 
or
The connection status will be stuck at a certain point

1. Verify that the Network APN is correct.
   

2. Verify that the server URL is correct.

   

3. Check with the technical support team that the SIM card has been activated.
   

4. If you are using a local SIM card, ensure it is an internet-ready SIM card. Subscribe to an active data package or insert an internet-ready SIM card.
   

5. Make sure the SIM card you are using is active and country-profiled if you are using a roaming SIM card. Contact the service provider for more information.

1. Confirm that the server URL/IP address is whitelisted for the SIM if there are restrictions for RMS SIMs in your country. Consult your local

SIM provider for more information.

COM LED is Green and Blinking Slow

1. Confirm the modem is properly connected. If not unscrew the modem connector and properly screw it back in a clockwise direction.

2. Reposition the modem, and try multiple locations to improve the network reception. Also, ensure crosslink foam is intact

3. If you are using a local SIM card, confirm there is an internet-ready SIM card present.

Wrong time stamp

1. Ensure the GPS time stamp is accurate, if it is not, proceed to the next step

2. Enhance the connection between the Elara and the antenna
   

   

ELARA Unit Not Upgrading

1. Confirm that the Configuration files in the SD card are in the proper order (Expected Files: ELARA.GIB and a folder called "VERSIONS" containing the ELARA.BIN file only). It is recommended to delete all existing files & recopy new Elara files to the SD card

At least one of the MODBUS devices is connected, but others are disconnected

1. Confirm the Elara is on the latest version, if not, upgrade the Elara Unit

2. Confirm the ID and Baudrate configured on the device are correct and match the ID and baud rate assigned on the power center. if not log in to the device and configure the correct ID and baud rate

3. If the device uses different physical and virtual IDs, confirm both IDs are correctly configured. Refer to respective device documentation on the knowledge portal

4. If there are multiple hardware or software versions of the same device, confirm the right one is selected on the power center. Check the device tag or log in to the physical device to confirm the versions

5. Confirm the Device power and communication cable are properly terminated, Rewire the device according to specifications. Refer to respective device documentation on the knowledge portal

6. Confirm Device is configured on the Port-1 Device section. Reconfigure the device as a Port-1 device

All MODBUS Device is Disconnected, none is connected

Confirm the RS485 connection between the terminal block and the Elara RS485 green connector. Check continuity between the RS485 terminal blocks and Elara RS485 Port-1 pins (Do same for A & B).

1. Check the

“Server URL”, and “Network APN” and the modes in both Port 1+2 (Port 1 must be the host and Port 2 binary).

Elara Configuration is OK on the Power center, all LEDs are green, but not reporting on ZON

1. Confirm the Unit ID on the Power Center matches the Unit ID on the Elara labels. If not, replace the Elara and sent the Elara with the wrong ID for reconfiguration of the ID

2. If the Elara is installed the same day, you may use the clear Internal log button on the power center. Note that data stored locally in the unit will be lost.

   

   3. Make sure that the time stamp is accurate. Otherwise, follow the troubleshooting steps for the wrong timestamp

There is no voltage on input 5 on the Elara
or
The hatch is open on ZonMax  

1. Ensure that the two cables connected to the sensor in the Tray/Metal Box are secured on both sides.
