[dsg-svt] [New Logentry] Re: SVT Coolant Leak Sensor for Hardware Interlocks

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).

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.

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.
