3.3 Maintenance Procedures
3.3.1 Check of Controller Air Vent Holes
If the air vent holes are blocked, the controller may overheat and malfunction.
To avoid this, perform check on the air vent holes to make sure that air is flowing
freely through them.
Fig. 3.2 Controller side views
a) If there is any obstacle, move it away from the air vent hole so that air flow is
not blocked.
b) Make sure that no contaminant is left on the air vent holes. If any contaminant
is left on the vent hole, remove it.
c) If the controller is placed sideways, make sure that the air vent holes on the
bottom surface of the controller are more than 11 mm away from the floor
surface. Always keep the space of 11 mm or over. The length of rubber shoe
is approximately 11 mm.
