The safe lift control is an additional (and optional) safety feature which, if configured, allows the eINST remote control to enable or disable the lifting of the load depending on the hook’s status.
> If the hook’s status is either open or closed, the relay will be closed, allowing the crane to lift the load.
> If the hook’s status is NOT fully open or closed, the relay will be open, not allowing the crane to lift the load, but it will allow to lower it.
To activate it, view the following video.
