chasing down how they prove the 235 degree safety switch is working after if the high limit switch fails?
A 235 degree safety switch? Never heard of it.
I work on U.S. units. You're apparently in a foreign market. Given that manufacturers sometimes must incorporate additional safeties in equipment designs for equipment sold abroad, you made me look in the manual. I found no such safety switch. The high limit IS the safety - designed to disable the fryer if the main temperature control fails and causes a run-away or over-temperature condition.
Per your model number, that is a 17kw dual-vat unit. Dual vat means that it's a single, standard sized vat that has a partition down the middle so each side operates independent of the other and able to accommodate a single basket.
Is that what you've got?
If so, then NON-CE dual vat units, the high-limit used in those opens at 224°C. For CE dual vat units, the high-limit in it opens at 213°C. In either case, the high-limit is designed to automatically reset at around 177°C.
Thanks fro the response!
That is the correct unit we have 17kw Dual-Vat. How do you test the high limit switch to get to 224 deg C simulating a faulty controller or over temp condition.
Doing that test requires temporarily altering the fryer's circuitry and should ONLY be performed by a factory-trained technician. Otherwise, without proper knowledge and understanding of the circuit's operation...and the use of suitable test equipment, there could be harm done to the fryer, the person doing it or could result in a fire.
So...NO, I cannot share that information.
Why do you feel a need to test it?
