Hi Guys
Need some assistance with a fault that has appeared on a SM331 AI module.
It's fitted into a Fire and Gas detection system I have just installed a new detector head replacing an old one and as soon as it was fitted the SF red LED came on.
I have checked the wiring and all the other sensors in the system have been connected the same way.
The module is getting 24vdc.
All other detectors connected to the module are off as well, so no displays on any detector. I think it's down to overflow error as when I inhibit each detector instead of saying normal on the inhibit window it says over.
I'm new to working with PLC's so any help would be greatly appreciated.
Thanks
