Yale ERC050:
ERC050GHN48TE084 forks drift when being lowered

The problem i am having is when the forks are raised you go to lower them and sometimes once you let off the mini lever it continues for a foot or so of decent.. i have tried a new mini lever, i pulled the solenoid and valve to clean them and check for damage.. i probed the back of the solenoid electrical conector for the signal. when the mini lever is released the voltage stops imediatly, but the forks still coast.. do not have the pasword to calibrate mini levers.. any help would be great..

I've seen this happen before in a zapi controlled system.
There is a setting in the hydraulic setup that is like a ramp speed or a delay for the lowering control. We had to go into several trucks when they first came out and adjust this setting so it would stop quicker when the control lever was released. For some strange reason the factory had them setup with a delay and it was causing alot of complaints with the customers because the forks would not stop immediatly when the lever was released.

It could also as suggested be a cylinder problem, air in the line or even a slow or sticky solenoid valve. But if it is consistent it may just be a control setting.

just some things to consider while troubleshooting

What type of upright do you have.2 or 3 stage with freelift. Could be a problem in one of the hoist cylinders
