10. FSK pcb (Qwes-ACT models only) - 11. Photoelectric sensor (Qwes-H/HR models only)
4.2.3.2 Velos Box
In Qwes-LEG models, a velos box is installed to convert the analog
antenna signal to a digital signal that is appropriate for the multiboard
pcb.
The velos box is installed in the control unit.
4.2.3.3 Air Valves Block
The air valves are solenoid valves and supply pressurized air to the
cylinders of the feed dosing unit(s).
The air valves are installed on a valve terminal. A standard configuration
has one solenoid valve and five blanking plates. If an additional feed
funnel is installed, an additional air valve is also installed. The valves are
controlled by the multiboard pcb.
4.2.3.4 Photoelectric Sensor
The photoelectric sensor has a housing that contains an emitting
element (infrared LED) and a receiving element (photodiode). It is
installed on a bracket on the base plate of the control unit.
The photoelectric sensor gets input when a cow is in the COSMIX S.
The photoelectric sensor sends output to the multiboard PCB.
