Fitting the protective membrane
For special applications such as in the food industry, the
keypad must be protected against the ingress of dust, liquids
etc. In this case fit the protective membrane over the display/
operator unit.

Danger!
Ensure that the diaphragm fits snugly in the groove of the
display/operator unit. Otherwise a proper seal cannot be
guaranteed and particles may enter underneath the
membrane. This may cause malfunctions in the keypad.
In food industry applications, there is the risk of bacteria
building up underneath the membrane.
