CI-9110 3-7 Board Setup
FAIL-ZERO MODE
(Both Jumpers in B position)
In the "B" position (if the Guard signal remains TRUE), a failure of the AI Command Input
signal (value fails below 0%) causes the pressure output to decay to 0% of scale and remain
there until a normal AI is received. Should the Guard Input go FALSE prior to the AI
command failure, the last pressure output value will be held.
