How to Use Blu-Link

...

Tip
Note You can use Blu-Link without an ETU. It will work as a smart fuse and a multifunctional wattmeter enabling you to, e.g., read Telemetry data.

...

Open the stock cover
Remove the stock buffer tube end cap
Plug in your AEG/ETU into the Blu-Link OUTPUT connector
Plug the AEG battery into the Blu-Link INPUT connector
Insert Blu-Link and the battery into the stock buffer tube
Replace the stock cover
Replace the stock buffer tube
Enjoy airsofting

Troubleshooting

...

LED	What happened:	What to do:
Image Modified 1 s on start	Self-test completed successfully	Blu-Link is OK Wait for further LED indications
Image Modified	Blu-Link has been connected correctly
Image Modified BLINKING for 120 s	Blu-Link is ready for Bluetooth connection®	Connect Blu-Link to GCS
Image Modified	Self-test failed, Bluetooth® connection is not possible	Disconnect the power supply from Blu-Link, wait 10 seconds and reconnect the power supply If you have a USB-Link, connect it to the INPUT Blu-Link connector, go to Diagnostics in GCS, check Blu-Link DTCs and follow the instructions there Contact us at support@gatee.eu
Image Modified BLINKING	No Blu-Link firmware installed Self-test failed, Bluetooth® connection is possible	Install Blu-Link firmware via GCS Connect Blu-Link to GCS, go to Diagnostics in GCS, check Blu-Link DTCs and follow the instructions there
Image Modified for 120 s	Blu-Link is connected correctly via Blutooth®	Enjoy using Blu-Link
Image Modified	Blu-Link firmware update in progress	Wait until the firmware has been updated Keep the device with GCS as close as possible to Blu-Link
Image Modified	Battery saving mode Battery disconnected	Enjoy using Blu-Link Connect battery
Image Modified	Discharged or damaged battery Battery Deans-T connector is not compatible Damaged power cables	Charge or replace the battery Use the Deans-T battery connector included with the INSTALLATION KIT Replace power cables
Image Modified BLINKING	Overload, DTC displayed: 2 – ULL, 3 – OCP, 4 – SCP, 5 – OTP	Read what to do in the next section or connect Blu-Link to GCS and check the Diagnostics tab
Image Modified BLINKING	Excessively low voltage, DTC displayed: 1 – UVP1, 2 – UVP2, 3 – UVP3	Read what to do in the next section or connect Blu-Link to GCS and check the Diagnostics tab

DTC Codes

Diagnostic Trouble Codes (DTC) indicate basic malfunctions and problems with your battery, AEG, ETU or Blu-Link. You are notified about them by a LED blinking for 120 s after the problem occurs. The Blu-Link DTCs can later be read and cleared in the Diagnostics tab in GCS.

...

Tip
Note If you are using an ETU connected to Blu-Link, also check the ETU DTCs. Blu-Link is designed to withstand higher power load and lower voltage than an ETU, so in most cases, ETU protection is activated earlier and Blu-Link does not detect the problem.

LED	WHAT HAPPENED	POSSIBLE REASON	WHAT TO DO
Image Modified	ULL – User load limit exceeded	The load limit has been set too low in relation to AEG configuration Other possible reasons are the same as in the case of OCP or SCP	Modify the adjustable smart fuse settings Follow the OCP or SCP guidelines Contact us at support@gatee.eu
Image Modified	OCP – Blu-Link has detected excessive current activating overcurrent protection	Motor damaged Motor or gearbox jammed Motor connection short circuit	Replace motor Unjam motor or gearbox Check and fix motor wire insulation
Image Modified	SCP – Blu-Link has detected a current over 270 A activating short circuit protection	Motor damaged Motor or gearbox jammed Motor connection short circuit	Replace motor Unjam motor or gearbox Check and fix motor wire insulation
Image Modified	OTP – Blu-Link temperature is too high activating over temperature protection	Excessively high outside temperature in combination with a tuned replica Frequent short circuits and Blu-Link electrical overloads	Wait until Blu-Link temperature drops
Image Modified	UVP1 – Battery protection was activated	Battery discharged	Charge battery
Image Modified	UVP2 – The voltage dropped below critical level for Blu-Link to work properly	Battery discharged The battery is worn out and has excessively high internal resistance Inadequate battery type for current AEG configuration Too much electrical resistance between Blu-Link and the battery Motor too powerful for the battery connected Motor connection short circuit Jammed motor Damaged motor	Charge battery Replace battery Use battery of greater capacity or voltage Do not use any adaptors Use standard or high-torque motors instead of high-speed ones Check and fix motor wire insulation Unjam motor Replace motor
Image Modified	UVP3 – Protection against battery overdischarge activated immediately after battery was connected	The number of cells differs from the number set in GCS Battery discharged	Set the same number of cells in GCS as in battery Charge battery
