look for the unload valve controller it should have to hose . on the top of the solenoid for the unlod valve is an small button that activate it. Press it. And take a look. If any hose is broken.
Also check on the controller and look foe the hardware submenu then look for the unload system and open the aensor menu
Press the button that we talked on the previous steps and lool if it chenge it state from on and off.
In caae sebsor is bad replace it. You should have and spare kit that usually xomes with the magnus.
in case hose is leaking compresses air , replace it.
Also check for the unload air cylinder movement, if the seals are damaged it won't move.
