5.2.7.2 Voltage Supply for Hood Fans
The increase in placement performance, optimization of travel paths, rotated gantry and the overlapping
of individual axes leads to increased heat generation inside the machine. This heat can affect the
placement accuracy and the MTBF times. For this reason, each machine hood has been equipped with
four fans for cooling the processing areas.
5-13: Voltage Supply for Hood Fans
The fans are supplied with 24V from the computer unit by the DC/DC converter and are switched via the
safety circuit.
