Does this have a fork height sensor? it will be on the left side upper corner, with a small belt.
If not you may have a problem in the handle or the lift limit is enabled
Lift Limit Without Override (N35ZDR, N45ZR, N30ZDR, N35-40ZR)
Use this setting to enable or disable the Lift Limit Without Override option. Setting the parameter to ON will enable the option, OFF will disable the option. The encoder hardware must be correctly installed along with the settings made for the free lift and lift limit heights. These settings can be made with ETACC.
