Minilab service Posted May 25, 2021 Report Share Posted May 25, 2021 If you are talking about circulation pumps then check level sensors and temperature protection sensors. Quote Link to comment Share on other sites More sharing options...
Dennis-fotogold Posted December 19, 2021 Report Share Posted December 19, 2021 Hi, I have the same problem, the pumps sometimes do not switch off, what could be the cause? I assume that : level sensors and temperature protection sensors - is if they do not turn on But if they don't turn off ? Thanks Zdenek Quote Link to comment Share on other sites More sharing options...

Thanks Zdenek Are you talking about the circulation pumps or the replenisher pumps? In what situation are you experiencing the pumps not switching off? Obviously when the machine is in normal operation the circulation pumps will be running, and the replenisher pumps will be operating on and off while prints are being made.

Dennis-fotogold Posted December 19, 2021 Report Share Posted December 19, 2021 In the evening when I turn off qss32 and activate the timer, sometimes (about 2-3 times a month) some pumps will remain working I have to turn off the main circuit breaker, then I turn on QSS, I start to turn off and activate the timer and the pumps are already off Quote Link to comment Share on other sites More sharing options...
Dave S Posted December 19, 2021 Report Share Posted December 19, 2021 Check the date and time is correct. Check the program timer times are set correctly, if the off time is set later than the time you are switching it on to the program timer the pumps will remain on until the off time is reached. People often seem to get confused by the off time setting, and set it to the time they close the shop, this is incorrect. The off time should be the latest time you want to machine to remain on for while in timer mode. When you press the yes key the machine goes into operation mode and the program timer is disabled. Normally it’s something like this:- On 07:30(am) The machine will be ready for 08:30 Off 10:00(am) The machine will remain heated until 10:00 then will switch off if nobody has put the machine into operation mode.

Dennis-fotogold Posted December 20, 2021 Report Share Posted December 20, 2021 oooo, You are right, You are best I turned QSS off at 12:15 and the timer is set at 12:20, so the pumps remain on When I switched the machine off and on again it was already after 12:20 and therefore the pumps were already switched off Thank you very much for the explanation Zdenek Dave S 1 Quote Link to comment Share on other sites More sharing options...
