Congratulations on your Blu-Link!

...

Notice
You can use Blu-Link without ETU. It will work as a smart fuse and power analyzer enabling to, e.g., read telemetry data.

How to read 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. The 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

OVL – The load limit was exceeded.

  1. Too high load

  1. Contact us at support@gatee.eu

OCP – Blu-Link detected too high current. Overcurrent protection was activated.

  1. Too low current is set in smart fuse settings

  2. Motor is damaged

  3. Motor or gearbox is jammed

  4. Motor connections' short circuit

  1. Adjust smart fuse settings

  2. Replace the motor

  3. Unjam the motor or gearbox

  4. Check and fix the motor wires' insulation

SCP – Blu-Link detected current over 270 A. Short circuit protection was activated.

  1. Motor is damaged

  2. Motor or gearbox is jammed

  3. Motor connections' short circuit

  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.

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

  2. Frequent short circuits and Blu-Link’s electrical overloads

Wait until the temperature drops

UVP1 – Battery protection was activated.

The battery is discharged

Charge the battery

UVP2 – The voltage dropped below 1.5 V, which is 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 strong for the connected battery

6. Motor connections' short circuit

7. Motor is jammed

8. Motor is damaged

  1. Charge the battery

  2. Replace the battery

  3. Use a battery with more capacity or more 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 was activated immediately after connecting the battery.

  1. Number of cells is different than their number set in GCS

  2. The battery is discharged

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

  2. Charge the battery

Notice
There may be several codes notified displayed one after another, e.g., SCP and UVP2: 4 red blinks; 2 yellow blinks.
