Hi Stano You put "cold" PCB into the oven. What do you expect? Of course the temperature will go down. I don't think it affects the final result of soldering.

Wow, 15 degrees C is too much. Is this a new problem or new oven?

If it's a new problem several things you can check out. Thermocouple placement may have got knocked into the wrong spot, or it could be dirty. I've seen this happen after a PM and a blob of grease landed on the thermocouple. It could be a thermocouple going bad. It could be an I/O card going bad. Try checking/replcing the thermocouple first. If not, swap I/O cards from another zone and see if the problem follows the card.

If it's a new a oven, then you have a problem with the oven.

Can somebody help me? I have an Ersa Flow 7 but the hard drive from the PC is completely damage. I need a copy of the software in order to get my machine running but I do not want to pay Ersa for all kinds of fees to get a copy. I do not mind paying as long as is cheap. Thanks.

Don't know that oven or if the layout is similar at all to a Heller, but in our 1500s you could lose a blower and not get an alarm until a large board blocked vertical airflow.

At that point the thermocouple in the faulty zone would then lose heat moving from the opposing zone's frantically compensating heating element and trip the alarm.
