Example: Check IO conguration
I/O summary
Alarm:
IO conguration error
IO conguration error
If you get an “IO conguration error” alarm after setting main
switch in ON position, the reasons can be:
• Not all enabled IO functions have been assigned to a
hardware input or output
• The number of enabled IO functions exceeds the number of
available inputs or outputs of the controller
IO summary
Go to Main menu -> IO Status -> IO summary
If the number of enabled IO functions exceeds the maximum
number supported by the hardware, an exclamation mark “!” will
be shown at the IO type in question� This means that you will have
to disable some of the IO functions via the conguration menus
of the suction groups and condenser in order not to exceed the
maximum available inputs or outputs�
If no exclamation mark is shown it means that at least one IO
function has not been assigned to a hardware input or output�
This means that you will have to go into the IO conguration
menu of each IO type, select a free input/output and select the
missing function (if a function is selectable this is the reason for
the IO conguration error alarm)�
An exclamation mark is shown
when max. number of IO is
exceeded !
