8.9.2.5 Lifting System
For the CAN handle, the lift signal is sent to the main controller through the CAN
message; for the mechanical handle, the lift signal is sent to the main controller directly
through the hardware signal.
Lifting Process
The lifting motor is connected to -P and B +of the main controller. When the main
controller receives the lifting switch signal, it outputs DC power to make the lifting motor
work. When it reaches the top and triggers the lifting limit switch, the lifting limit switch is
disconnected. The signal stops the output current and the lifting motor stops.
Lowering Process
The lowering switch is closed and the main controller outputs 24V power between its
B3 hole and B+ hole. Energize the lowering valve by opening its port and lowering
down the fork.
