F Red Turns off when the board

The Analog I/O board may only be used in the first I/O slot.
This also means that only one Analog I/O board can be used
per system.
The Analog I/O board, DSQC 209, converts analog input
signals to digital and vice versa. The signal level equals 10V
in and out with a resolution of 12 bits including characters.
The board is supplied with ±15V, either internally or externally.
The analog side of the board is galvanically insulated from
the system. The first output, is the current output, which can
drive or sink a current of 20 mA. The board has a test input/
output on the front panel and a test switch which can be
used to test whether the board is working properly. By
turning the test switch to the position for measuring inputs,
a power supply can be connected to the test terminal
(protecting resistance should be used in the serial channel)
to test whether the inputs are working properly.
If replaced, there are no adjustments or procedures required.
The I/O window can be used to check the status of the inputs
and outputs. Outputs can be controlled manually and inputs
can be read from the I/O window. Common causes of errors
are cable faults or faults in external equipment. If none of the
channels work, check that the internal or external ±15V
supply is OK and correctly connected. If the red F-LED is lit,
the board is probably faulty or the system parameters are
incorrect (i.e. the board is not defined). Refer to the Manual
Operation (page 11-19) in this chapter.
