1.) Loss of a block within the group. (I.E. any failure which causes the block to no longer communicate on the Genius Bus such as loss of power.)

2.) Autotest failure of the power feed output (point Q16) of any of the blocks in a group.

For discrete output groups there are also two types of faults which may prevent the output autotest from continuing to execute for that output group and thus cause an I/O shut down for the outputs in the group.

1.) Loss of a block within the group. (I.E. any failure which causes the block to no longer communicate on the Genius Bus such as loss of power.)

2.) Output autotest failure detected of a type which could potentially prevent a normally energized output from being tripped off. An example is the short of a source block output to +24 Vdc.

After completing the selections for Autotest, select OK.
