Functional description
Switch on The Control Panel does not have its own mains power switch. As soon as
the power supply is switched on the control panel is activated.
Switching off Control software, as typically applied in Control Panels, enables the
assignment of different rights to all users. A user who is not entitled to shut
down the software may not switch off the Control Panel as an attempt to
shut it down when the software is running could result in the loss of
software data on the Compact Flash memory card (CF card).
If the control panel is shut down while the software is writing a file onto the
CF card, the file will be destroyed. Control software typically writes
something to the CF card every few seconds, so that the probability of
causing damage by switching off while the software is running is very high.
Operation The Control Panel’s membrane keypad may only be actuated by fingertips.
Do not operate with objects
Attention
Attempts to actuate it with other objects can easily result in the destruction
of the device. Neither may the membrane keypad be operated with a
touch screen pen.
The touch screen may only be actuated by finger tips or with the touch
screen pen. The operator may wear gloves but there must be no hard
particles such as metal shavings, glass splinters embedded in the glove.
