kodakman7 Posted December 21, 2021 Report Share Posted December 21, 2021 I have recently moved the 2901 to another location (150m) and split the unit to move. We retanked at the new locn, had some issues with stb 1 &4 pumps and replaced them as part of retanking the machine. It started and we ran it ( but not putting production through it) for 3 days without issue. On Monday it was started up at 8.30am and then 10.00 it shut down and threw out the supply circuit breaker at our switchboard (not the one on the lab). Since then, if we start the machine up by turning the breaker on, the machine starts up but then throws the breaker after about 10-15 seconds. I had an electrician test the supply and circuit whih was clean, so I am left to look at the Noritsu I am assuming it is something starting up in the lab causing the problem. Suggestions on where to start looking ? What is the sequence of the startup? Was wondering about the heaters. Kind regards Russell Quote Link to comment Share on other sites More sharing options...
Dave S Posted December 21, 2021 Report Share Posted December 21, 2021 Yes I would start with the chemical heaters. try unplugging all the chemical heaters and see if it makes any difference. If it no longer tripps, plug one heater in at a time. The STB heater is a 1000W one, so maybe try unplugging that one first. Quote Link to comment Share on other sites More sharing options...

Dave S Posted December 23, 2021 Report Share Posted December 23, 2021 Great, here are some part numbers for some heaters you can use. It doesn't have to be a 1000W heater, the later 32 series use a 600W heater I029115-00 Heater 600W I029121-00 Heater 800W I029116-00 Heater 1000W Quote Link to comment Share on other sites More sharing options...
