8.1 Fan Filter Cleaning

Regularly clean the two DCV controller ventilation filters to maintain the airflow in the DCV controller. If
the filters become blocked, the temperature will increase, resulting in DCV controller malfunctions.
 Cleaning Cycle
At oil and steam-free locations: clean once every six months.
At locations subject to oil and steam: clean once every two weeks.
If the DCV controller is placed outside the robot enclosure: clean once every two weeks.
Figure 8.1 shows the locations of the DCV controller ventilation filters. One is located on the front of the
DCV controller and the other is located on the side of the DCV controller.
Notes:
1. When cleaning, do not aim an air gun directly at the filter to clean it. If there is water inside the air
gun, it will cause damage to the DCV controller components, or cause a danger of short circuiting
when the power is turned on.
2. The correct cleaning method is to remove the filters and then clean them. Replace the filters into the
DCV controller after cleaning is complete.
