1. Leave the controller switched on (if the APDs are overheated, they can cool
down sooner, because the fan stays on).
2. Have a look at the ambient temperature in the room. Is it very warm? If so,
try to get it cooler.
3. Is something blocking the ventilation of the controller? Make sure that is not
the case.
4. Wait at least 30 minutes to let the APD module cool down.
5. Restart the system, observing how the LEDs of the APD module are behaving.
6. If they still report a problem, call qutools support.
The most probable cause for this behavior is that the APD module is overheated.
This can happen when the ambient temperature is too high (
> 25
◦
C) or when
the ventilation slots are blocked. Please make sure that the ventilation openings
beneath, at the back and at the front of the controller are kept clear.
