BFT SubR not opening/closing sometimes

[SamA]

Hi Joe,
thanks for your reply. It's the underground Sub R motor with slowdown facility fitted in 1996. The good news is that as the temperature has now risen to above zero they are working again as before and opening and closing fine. The only issue I have had for some time is that on closing, one leaf stops mid cycle then starts again and closes. I'm wondering if it needs bled and/or topped up with fluid.
Regards
Jim

Hi Jim,

Usually if the gate stops halfway through a cycle this is due to resistance, I would recommend increasing the force via the control board incrementally or you could top the fluid up to make sure the hydraulic pressure is where it needs to be to bypass certain resistances.

Kindest Regards,

Sam.
