This morning we had a problem with our Fluid Bed Furnace, It started with the flames going off and only to realize the temperatures
on the screen were not changing value and yet the ones at the OMRON limit were dropping. We switched the panel on and off and the screen
brought a massage ‘PLC is in ERROR’ On opening the panel, the PLC was indicating error with the red light blinking and the panel was indicating
low air flow. We switched on the E-stop switch and we managed to start for 2 hours and the problem come back.
We have observed that the gas for all 3 zones went off. All the pilots were on while the PLC was showing an error & the touch screen had freezed.
Attached are the screen and PLC shots.
What could be the problem?
