When teaching in the MR329 it isn’t required to set the 3dead turn parameter if the block will reach the ground before running out of rope on the drum.
If you previously set the 3 dead turn and need to get rid of the saved information on CSS, unpair the hook height encoder, pair it. Turn off CCS and turn it back on. Teach the zero height, and the upper height and then escape out of the teach in menu. A prompt will warn you on startup that 3 dead turns has not been set.
This is important because if you have a crane that reaches below the base of the crane the 3 dead turn function may preclude you from going low enough.
You can get around this if you want by pulling out rope onto the ground and setting the 3 dead turns but it may screw you on the next jobsite.
to access the valves the A/C unit must be removed.
