Cleaning and servicing
The controller normally runs without wear and requires no maintenance. In order to ensure correct
function and safe operation it is necessary to regularly check that all connections are in good
condition and that air supply to the ventilation openings of the housing is unhindered.
Procedure
Switch the controller off at the main switch and unplug the power plug.
Wait approximately 2 minutes to allow the energy stored in the capacitors
can discharge.
Check the power supply, the power supply cords of external consumers
and all motor cables for visible signs of damage. Damaged or cracked
lines must be replaced at once.
Check the ventilation slots on the front and rear panels. They must be free
of swarf and accumulated dust. If necessary, clean the slots with a
vacuum cleaner. Avoid blowing them clean with compressed air under
any circumstances! This could lead to swarf being blown into the interior
of the controller. Swarf and small parts could break free and cause
injuries. Use a paintbrush or soft brush if there is stubborn soiling.
If necessary clean the surface of the housing with a slightly damp cloth.
Avoid using aggressive cleaning agents or solvents. If liquid gets into the
housing by mistake DO NOT start using the equipment again, but have it
checked by a specialist.
