Congratulation on your new Blu-Link!

...

  1. The color of LED reflects on the problem type:

    1. Yellow indicates a warning

    2. Red indicates a critical problem

  2. Number of blinks determines what exactly the problem is (for reference, read DTC explanations presented later on in this guide)

DTC explanations

  • grafika - flaga w kolorze i z liczba plus strzałki wyjaśniające

  • dodać za liczbą mignięć znak “x” np. 2x

  • przemyśleć bardziej obrazowe oznaczanie liczby mignięć, np. warfet, 4 błyśnięcia:

Notice
If you use an ETU connected to Blu-Link, check also the ETU's DTC. Blu-Link is designed to withstand higher power load and lower voltage than ETU, so in most cases, an ETU protection turns on earlier and the Blu-Link does not detect the problem.

WHAT HAPPENED

POSSIBLE REASON

WHAT TO DO

ULL – Blu-Link has detected a too high load.

  1. User load limit was exceeded

  1. Modify adjustable smart fuse settings

  2. Contact us at support@gatee.eu

OCP – Blu-Link has detected a too high current. The overcurrent protection was activated.

Current limit set in the adjustable smart fuse settings was exceeded

  1. Motor is damaged

  2. Motor or gearbox is jammed

  3. Motor connections short circuitModify the current limit

  1. Replace the motor

  2. Unjam the motor or gearbox

  3. Check and fix the motor wires insulation

SCP – Blu-Link has detected a current over the set limit270A. The short circuit protection was activated.

Short circuit protection activation level set in the smart fuse settings was exceeded

  1. Motor damaged

  2. Motor or gearbox jammed

  3. Motor connections short circuitModify the short circuit protection activation level

  1. Replace the motor

  2. Unjam the motor or gearbox

  3. Check and fix the motor wires insulation

OTP – Blu-Link temperature is too high. Over temperature protection was activated.

Temperature limit set in the adjustable smart fuse settings was exceeded

  1. Outside temperature is too high in correlation with the demanding AEG

  2. Frequent short circuits and Blu-Link electrical overloadsModify the temperature limit

  1. Wait until the temperature drops

UVP1 – Battery protection was activated.

The battery is discharged

Charge the battery

UVP2 – The voltage dropped below level critical for Blu-Link to work properly.

1. The battery is discharged

2. The battery is worn out and has too high internal resistance

3. Inadequate battery type for given AEG configuration

4. Too much electrical resistance between Blu-Link and the battery

5. Motor too powerful for the battery connected

6. Motor connections short circuit

7. Motor jammed

8. Motor damaged

  1. Charge the battery

  2. Replace the battery

  3. Use a battery of a greater capacity or voltage

  4. Do not use any adapters

  5. Use standard or high-torque motors instead of high-speed ones

  6. Check and fix the motor wires insulation

  7. Unjam the motor

  8. Replace the motor

 

UVP3 – Protection against over-discharge of the battery. Battery protection activated immediately after the battery was connected.

  1. Number of cells differs from the number set in the GCS

  2. The battery is discharged

  1. Set the same number of cells in GCS as in the battery

  2. Charge the battery up
