ralphmalph Posted August 7, 2012 Report Share Posted August 7, 2012 BL and STAB tanks are way to hot and DEV will not come to temp. Happened all of the sudden out of the blue. See attached Please advise Thanks Quote Link to comment Share on other sites More sharing options...
relaxia Posted August 7, 2012 Report Share Posted August 7, 2012 Did you manipulate with heaters connections ? it really looks like you switched wires... or switched heaters in the tanks if not...check offsets a) find any thermometer available - the one for body heat measuring is very suitable. Go to SU-> settings-> processor-> temperature c) measure the temperature AWAY FROM THE HEATERS. if the measured temperatures are away from the machine readings - set the offsets: d) put the masured values in the right windows - press calculate. then press validate.

ralphmalph Posted August 7, 2012 Author Report Share Posted August 7, 2012 Thanks Relaxia I did not touch any connections. I shut the machine down over night and it is now back to normal. Very strange occurrence I could not get it in range yesterday no matter what I tried. If this happen again I will follow the steps you posted Thanks again for the reply Quote Link to comment Share on other sites More sharing options...
damooose Posted August 8, 2012 Report Share Posted August 8, 2012 Check your turbine washers in your bleach tank Strangely in my 1550 if it fails it ends up cooking both tanks when this happens the macihne turns off all heaters and waits for the temps to drop as starts them again but you would normally get a warning telling you your temps are beyond limits shut down macine or continue Blah Blah Blah. Could also be the tankboard starting to play up and or the impag board but that is a rarity.. Quote Link to comment Share on other sites More sharing options...
blusther Posted August 8, 2012 Report Share Posted August 8, 2012 For understanding, this machine only heats stab until temperature in standby, during printing the dryer heater maintans the stab temperature. Very important is the temperature inside your lab, in summer you can get this kind of problem and as damooose says: the circulation of the impelers in the tanks. If you want adjust the temperature with the potentiometers on the tank PCB you have to do it in the morning, There are test points (PT1=dev, PT3=BF,PT5=stab) and potentiometers P1=dev, P2=BF, P3=stab. Voltage to adjust 3,28volt for 40ºC and 3,062 for 38ºC. Put the voltage of BF and STAB a bit lower as for the correct temp. and then when the check LED's of each chemistry starts to flicker measure the temperature in tank and adjust little by little raising the potentiometers until you get the correct temperature. Now you have to check the temperature in the Chemie.exe and the calibration of the temp. probe and adjust them. In summer don't adjust the BF temperature not very far away of the developer temperature. If developer is 40ºC you cannot adjust 35 for BF but 38 will be better. Again for understanding: The adjustment of the temperature is done by potentiometer NOT BY SETTING. Hope I could help you. Quote Link to comment Share on other sites More sharing options...
relaxia Posted August 8, 2012 Report Share Posted August 8, 2012 don't touch any physical settings neither offsets yet. damooose - this would be one slot - not all tanks. here u have at least 2 slots affected. (1 bl/fix+ 3 stab heaters 3 turbines but on one temperature probe). additionally DEV is underheated...interesting machine could swap the slots in the tanks ralphie - look for the gremlins in the neighborhood - U have new people moved in from Ireland nearby ?
