Operator control
8.1 Device interface
SENTRON PAC4200
114 System Manual, 09/2009, A5E02316180B-02
Function keys: Key labeling - Key surfaces
The four function keys F1 to F4 enable operator input to the device:
● Navigation in the menus
● Selection of the measured value displays
● Display and editing of the device settings
The keys have multiple assignments. Function assignments and key labeling change
according to the context of operator input. The designation of the current key function can be
seen above the key number in the footer area of the display.
A short press on the key triggers the function once. Holding the key down for longer switches
on the autorepeat function after approximately 1 second. The function of the key is triggered
repeatedly while the key is held down. Autorepeat is useful, for example, for fast
incrementing of values when parameterizing the device.
