Lumentation Posted February 3 Report Share Posted February 3 Hello Everyone, We have a Noritsu V30 developer and the temperature of all the chemicals won't heat up, they perpetually drop as time goes on and we don't know what to do. One very big factor is that the Northeastern US is in a n almost record-breaking low temperature (outside it's currently 15F and with wind chill it's -3F. So we don't know if the V30 is completely failing or if temperatures are just so low that we can't expect it to get up to temp. We have our heat set to around 70F inside, but it's close to the floor that's fairly cold. The lab is backed up with orders already and we feel like it's a crap shoot to wait and see if it's the cold and fall further behind with orders, or if we can hope that after the temperature starts to rise outside we can expect the V30 to function. It's a borderline emergency for our situation so please let us know whatever thoughts you have and we would be incredibly grateful. Quote Link to comment Share on other sites More sharing options...
TECNOR Posted February 3 Report Share Posted February 3 First check the level sensor, in the main relay pcb check all fuses. Quote Link to comment Share on other sites More sharing options...
Lumentation Posted February 3 Author Report Share Posted February 3 Thank you for your prompt response. fuses look good. can you please explain what you mean when referring to the level sensor. I couldn't find anything referring to that part in the manuals Quote Link to comment Share on other sites More sharing options...
davidlam Posted February 4 Report Share Posted February 4 that is Safety design... IF one or more tank chemical level goes low, protection circuitry ( detected by level sensor(s) ) will turn OFF the pumps and chemical heater to avoid further severe damage . check the LID microswitch also Quote Link to comment Share on other sites More sharing options...
Dave S Posted February 4 Report Share Posted February 4 I'm assuming this machine has been installed and in use for a while? If not, check the mains wiring is correct. If so, go into input check, processor and check if all the circulation pumps show on or not. Quote Link to comment Share on other sites More sharing options...

Hey Dave, We've used it for 4-5 years at this point so we believe the wiring should be ok. We looked recently while the machine was in temperature adjustment and it showed the pumps being off. Any idea of what we can do or check next? Quote Link to comment Share on other sites More sharing options...
kodak_service Posted February 5 Report Share Posted February 5 Please post a photo of the display while waiting for heating and a photo of all pages in the menu MAIN MENU-CHECK -INPUT CHECK-PROCESSOR Quote Link to comment Share on other sites More sharing options...

The most likely cause will be high resistance contacts on the processor lid micro-switch, it is located in the back corner, near the extract fan. Probably the pump error alarm has been set to off (standard setting 3 Pump error) which is why there is no error. Quote Link to comment Share on other sites More sharing options...

I'm not sure what "standard setting 3 pump error" is, but I know a few months ago we put the machine into service mode to disable the circulation pump error alarm. Our machine was indicating that our CD circulation pump was faulty even though it was operating completely normally. Any ideas? Quote Link to comment Share on other sites More sharing options...

To fix the issue replace the micro-switch https://www.mouser.co.uk/ProductDetail/Omron-Electronics/D2SW-3L1MS?qs=0w99tykdtPJ5X%2Fslyh2IRQ%3D%3D Standard setting 3, pump error off, will have been the setting that you changed to disable the circulation pump error for the CD pump. There are 2 pumps on the CD, maybe one of them is faulty and not working properly. Quote Link to comment Share on other sites More sharing options...
