Check for Soiling
In general, all models of the AViTEQ controllers are maintenance free. In dusty
environments, however, dust can penetrate and collect. This can result in deterio-
ration of the cooling system for the control electronics and short circuits as a
result of soiled strip conductors.
We therefore recommend regularly checking for soiling and cleaning as neces-
sary:
$
Has dust penetrated? Determine the cause so that measures can be taken to
avoid the problem in the future! Clean the controller by vacuuming the dust
layer, e.g. with an industrial vacuum cleaner.
$
Check to see if the perforated plate in the housing has been plugged with
dust! Clean the controller by vacuuming the dust layer, e.g. with an industrial
vacuum cleaner.
$
Depending on the amount of dust in the environment surrounding the control-
ler, a suitable cleaning interval is to be set.
When cleaning with compressed air, note the in-house regulations regarding the
raising of dust!
Raised dust can mix with air and form explosive dust-air mixtures. Take appropriate
measures to eliminate the risk of explosions!
When connected to mains, dangerously high voltages are present inside the con-
troller. Touching electrically live components can be lethal! Before cleaning the
controller, switch off the current supply and protect against unintentional switching
on, i.e. by colleagues! Protect yourself from accidental contact with nearby electri-
cally live components or component groups!
