Lights flashing in sea water


(GLEIBER RANIERE GALVAO NOGUEIRA) #1

I put my BlueRov2 Hard Config. in sea water for the first time, and its four lights began to flash weakly. They were turned off. When I turned them on, they flashed strongly, like loosing contact. Worried, I came back home and did another dive in the swimming pool and then, everything worked normally, as always. I saw no sign of leakage.
What could have happened?

We have done a lot of tests in swimmingpoll and sea water.
The 4 Lumen Subsea Lights in swimmingpoll works perfectly, but in sea water they do not work well.
Please, see videos in https://1drv.ms/f/s!Ak5U2EjK4yRpivMurF53QNO6W9tV1w.
When the lights are OFF and some joystick command is acioned the lights flashes.
When the lights are ON and some joystick command is acioned the lights flashes strongly and go out.
Does anyone know what could be happening?

@Gleiber @marcos.anselmo We’ll discuss internally on Monday and get back to your e-mail. We aren’t quite sure right now.

Hi all,
I’ve dived only a couple of time, only in salty water. In “manual control” mode I have the control of lights level, but in “depht hold” and “stabilyse” mode lights are turned on and they blink indipendently (maybe related to rotor?). Is it possible to turn off them and to handle the lights level totally by controller?

I did have same problem when diving in salt water. One of the lights start flashing at app 1 Hz when lights was of. I could se a small amount of water inside when i held the light with lens downwards. The problem was a bad sealing at blind plug.Last light in the chain of four.

Hi @kdm, this sounds like an electrical/noise isolation problem. There may be some conductive path that should not exist, likely as a result of water ingress.
