librallama Posted April 9, 2017 Share Posted April 9, 2017 Hello, I have a rowe 548 and I was wondering if there was a way to shut off the cooling mechanism and just turn it into a vending machine which has a rotating turret. There's no option to just shut off the cooling because it seems the machine is set to shut off if the health sensor is compromised or above a threshold, so I'm wondering if there's a work around even if it involves soldering or buying some mod part.

AZVendor Posted April 9, 2017 Share Posted April 9, 2017 There is no way to do that because the health safety system is built into the logic board and will disable the machine if the temp goes above 42 deg for more than 5 minutes. It's all electronic. What are you planning to vend from it? Link to comment Share on other sites More sharing options...
librallama Posted April 17, 2017 Author Share Posted April 17, 2017 Is there not some method or apparatus I can use to give the logic board a certain volt reading? From my understanding, the sensor would detect it's 42 degrees and then send .42V. Is there a way I can trick the logic board into thinking it's constantly 42 degrees?

librallama Posted April 18, 2017 Author Share Posted April 18, 2017 Why would it not work to do that? It'd do the same thing as the health sensor, but it'd just give a false reading. Link to comment Share on other sites More sharing options...
librallama Posted April 18, 2017 Author Share Posted April 18, 2017 I'm legitimately curious, mb if I come off as aggressive. Link to comment Share on other sites More sharing options...
AZVendor Posted April 18, 2017 Share Posted April 18, 2017 You would need to emulate the passive sensor in the temp probe. I don't have any idea how you would do that. Link to comment Share on other sites More sharing options...
falls Posted April 18, 2017 Share Posted April 18, 2017 From reading the manual it has an "electronic digital thermometer". You need to work out if it is self powered and at what voltage. If it's only a 2 wire cct it is probably changing resistance by temperature, and can probably be replaced with a variable resistor. If the sensor board is powered externally and there is a 2 wire 'control' cct to the board (the .42 V you mention) you will need to add a voltage splitter including the variable resistor . Vin and Vout will determine the values of the resistors. Link to comment Share on other sites More sharing options...
