• Check if probe is bent or damaged
• Move probe to less turbulent area of the tank

Note: If this doesn't resolve the issue, you will need to replace your transmitter.

Note: If this doesn't resolve the issue, you will need to replace your transmitter.

Update the Transmitter's Firmware.

Update the Transmitter's Firmware.

If this doesn't resolve the issue, there may be water inside your transmitter that causes it to fail. If this is the case, you will need to replace or repair the transmitter.

• Tighten transmitter nut that attaches transmitter to probe.
• Tighten shorting block at bottom of probe.
• Ensure the inside connection between probe and transmitter is clean. If there is product or debris, wipe this connection down.
• Ensure there is no product buildup on probe.
• Ensure probe is not damaged.
• Check for potential water damage to the transmitter.

• Adjust HH level in strapping table and reprogram using SensorLink or Titan Install.
• Update Firmware to the transmitter.

Program a strapping table using SensorLink or Titan Install.

Reprogram the transmitter with the latest version of SensorLink or Titan Install.

TD80 transmitter ONLY

1. Cycle the power to the Transmitter.
2. Reprogram the transmitter.

Note: If this doesn't resolve the issue, you will need to replace your transmitter with a TD100.

If this is a brand new unit, this error code appears because the tank has not been filled yet.

• Update the firmware on your transmitter. The latest firmware removes this error code. (Recommended option)
• Run your fingers up and down the probe to simulate loading liquid in your tank. This will also get rid of this error.

• Update the TD100 firmware to the latest version.
• Perform fluid calibration sequence by loading the tank with fluid and allowing the transmitter to self-calibrate.

Check if the shorting block is correctly installed on the probe.

Check if your probe is longer than the strapping table.

Note: This error will appear if you are connecting the transmitter right to the FINCH (without the probe) for testing purposes.

Update the TD100 firmware to the latest version.

Check probe and transmitter for damage.

• Update the TD100 firmware to the latest version.
• Check probe and transmitter for damage.

• Cycle the power to the FINCH II.
• If the error appears again, update the ESP module firmware.

FINCH II-W/6W Display ONLY

For FINCH II Displays: Check B-DIP, switch 3 is ON. Unlock the hardware setting by turning B-DIP, switch 4 OFF. If this doesn't resolve the issue, you will need to replace/repair your FINCH II.

For FINCH III Displays: Use Titan Install to configure your secondary FINCH III display.

1. First check to see if the FINCH II firmware is updated. More Info
2. Next, check if your relay mapping is correct. More Info
3. If both these things are good, try cycling the power to the FINCH II.

Note: If this doesn't resolve the issue, you will need to replace or repair your FINCH II display.

1. First check to see if the FINCH II firmware is updated. More Info
2. Next, check if your relay mapping is correct in SensorLink. More Info
3. If both these things are good, try cycling the power to the FINCH II.

Note: If this doesn't resolve the issue, you will need to replace or repair your FINCH II display.

1. First, check your Fill or Fall alarm levels. More Info
2. Next, check if your relay mapping is correct. More Info

Inspect and fix the wiring connection between the transmitter and the FINCH.

Note: If this doesn't resolve the issue, you will need to replace or repair your transmitter.

Cycle the power to the FINCH II or FINCH III.

Note: If this doesn't resolve the issue, you will need to replace or repair your FINCH display.

Use a digital multimeter to check the voltage. Ensure it is greater than 8V.

Look for corroded wire connections where the power cable connects.

Note: The E0802 error code may be accompanied by other codes such as E0780. There may be multiple errors happening as a result of low or unstable power.

Use a digital multimeter to check the voltage. Ensure it is less than 30V.

Look for wire connection issues along the input power.

1. Cycle the power to the FINCH II OR FINCH III.
2. Check to see if the FINCH II OR FINCH III firmware is the latest version. More Info

Note: If this doesn't resolve the issue, you will need to replace or repair your FINCH display.

Check input voltage.

• If above 8V, the display is defective.
• If below 8V, there is a wiring problem.
