Functional Safety HiC2883
Operation
Proof Test Procedure
1. Prepare a test set-up, see figure below.
2. Test the devices in the mode of operation they are used in. If necessary,
change the configuration of the device. Verify the input and output values as
given in table below.
3. Set back the device to the original settings after the test.

Tip
The easiest way to test HiC devices is by using a stand-alone HiCTB**-SCT-***-
**-** termination board. In this test, it is not necessary to disconnect the wiring of
the existing application. Faults in a subsequent wiring can be avoided.
