<p>Since the AUX1 LED on the controller works and the AUX1
controller monitor output does not, I'll be submitting a PR for a
replacement controller.</p>
<p>The ADC was connected to the AUX1 monitor output which should
have an output voltage when the controller AUX1 LED is on. <br>

<p>We found that the Y1 output is a pulsed output, which
won't work with the cRIO as it is currently implemented
(averaging and/or delayed trip will allow it to work).</p>
<p>Despite the manual saying that for an NPN output the
COM+ terminal should be used, when we tried that the
circuit breaker in the box tripped and even though we
used the override keys the SVT still turned off since
those signals are after the breaker.</p>
<p>We also didn't see any voltage on the ERR, SUB, or AUX1
outputs no matter what the leak sensor was indicating.
However, the AUX1 LED on the controller matches the leak
sensor status.</p>
