11.4 The control panel
The control panel comprises 3 sections:
•
the ESC, SET, control keys
•
the 3-digit 7-segment display
•
dedicated icons for operating status
indication
A flashing icon always indicates a faulty situ-
ation!
Exception:
When switching the unit on, the
complete display flashes 4 times. Then, the
power-on-LED blinks while the device self
test is run.
The
control keys
enable navigation in the
menus and submenus. Their function is as
follows:
„ESC“: cancellation or return to previous level
: move up/down within a menu, sub-
menu or selection list.
„SET“: accept and store a selected setting.
The 3-digit
7-segment-display
serves for
outputting of operational and input data as
well as error code presentation. When control
software expects an input the digits are
blinked. Display semantics are determined by
lightening-up of one or more icons related to
a specific operational situation or device con-
trol environment.
