Mounting the Protective Cover
The protective cover is provided for using the device in aggressive
environments. This protects the display and the keypad against mechanical
damage or destruction. Protection to IP65 is maintained.
The protective cover can be opened so that the keypad can be used.
The protective cover can be closed with a sealing facility to provide protection
against unauthorized operation.
Before mounting the display/keypad, fit the protective cover.
ATTENTION
Ensure that the membrane fits snugly in the groove of the
display/keypad.
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.
IMPORTANT
If the protective membrane needs to be replaced, the
display/keypad must be removed. Replace the membrane
and refit the device.
