Motor thermal/ Refrigerator

Hi guys, I'm new to LinuxCNC, I'm using a Mesa 7i76E card. I'm having trouble generating an alarm on the machine due to a spindle motor problem (the motor has a thermal NC, when heated it opens) I'm not able to make the link on the controller. The same problem happens because my machine has a refrigerator (it is independent of the machine, but it has a signal that any problem in the refrigerator it sends a signal to the controller for example: "problem in the refrigerator" and the machine stops) and I am unable to create and generate the link as I got on the buttons for example: emergency, cycle start, stop, etc ... Anyone can help thank you.

If it was OK just to trigger an estop, you could tie these alarms together using the estop-latch component.
There are other ways but I'm not clear what you want.

The motor thermal is an NF resistor, which when I open (heat) I intend to generate a spindle alarm (not turning on the spindle anymore), the refrigerator already sends a 24vcc signal to the refrigerator in a relay when there is a defect, the relay opens and does not returns the signal (I also intend to block spindle until the problem is solved). I don't know if this information has clarified?

*NC resistor

So for a crude example:

loadrt message names=spindle_overheat, chiller_fail messages="Spindle overheat, Chiller fail"
addf spindle_overheat servo-thread
addf chiller_fail servo-thread

net some_hardware_input_pin spindle.0.inhibit spindle_overheat.trigger
net some_other_hardware_input_pin motion.feed-inhibit chiller_fail.trigger

sorry, more gave this error attached

Sorry, you need to remove the spaces surrounding the"="s
in the loadrt line (I fixed my previous post to reflect this change
