Industrial cooler alarm issue

[Imothep]

Hi all !

I have a cooler for my water cooled spindle equiped with an in-built alarm relay in case off high temperature or pump failure, the alarm is wired to the I4 input of the AXBB-E.
My problem is the alarm output of the cooler automaticly change state when the machine is turned off.
The cooler is controller by the M8 function so it will only turn on when a cycle starts, and turn off when the cycle stops.
That's means that the input is triggered in UCCNC when the cooler is not powered, so I can't configure a trigger function to automaticly RESET in case of problem with the cooler.

Some solutions are coming to my mind :

-Alaways turn the cooler on when the CNC is powered (I wish I can avoid this solution because the cooler make a lot of noise and it is a waste of electricity).
-Don't use the alarm (my last option for obvious reasons).
-Use a external NO relays in parallel with the M3 and M4 spindle relays so it only let the alarm signal reach the I4 input of the board when the spindle is powered (need for more relays and extra work for me :'[ but probably the only option).
-Finaly the best option for me would be to set an I/O trigger with a double condition : run the RESET function only when the I4 input and the M3 are both active at the same time.

I hope I made myself clear with my explainations.

Any ideas ?
