kamal pasha Posted April 5, 2011 Report Share Posted April 5, 2011 Dear Perica, Would u pls confirm me that rack motor of dks-3 is driven by +12v dc or +24v dc. Thanks Quote Link to comment Share on other sites More sharing options...
pskaro Posted April 5, 2011 Report Share Posted April 5, 2011 Actually there is no fix voltage for the rack motor because its voltage is regulated by the Tank PCB to mentain the proper rack speed using the information from the coding wheel near the motor and speed set by the chemical choise set in the Chimie.exe. "By knowing the rack motor characteristics as well as the exact value of each components of the tank board, we are able to calculate the THEORETICAL speed of the motor, its returned frequency value for a given analogic instruction and its corresponding voltage applied to the motor." This regulation is derived from +24V input, but on the DKS2 it was about 9V when DKS is working with the 131Hz rack speed, on the DKS3 I never measured the voltage when working, so I do not know what would be the closest voltage.

kamal pasha Posted April 5, 2011 Author Report Share Posted April 5, 2011 Thanks Perica,actually tankk pcb of our dks-3 is gone(2nd time). it is not availavle in our stock. it will take time to get it from distributor as its also not ready in thiere stock. So by this time have any alternative way to drive the rack motor. Need ur help regarding this. Quote Link to comment Share on other sites More sharing options...
pskaro Posted April 5, 2011 Report Share Posted April 5, 2011 You can connect the motor with some power supply which can be fine adjusted wia some potentiometer, by the way if you have KIS 24V power supply, it can be used also. Set start voltage to 8V and observe the reading off the motor speed (in Hz) on the screen and adjust to get correct speed (as it was when everything was working normally) which depend off course off the chemistry used. This is workaround which is not precise but it could help for some time, while you are waiting for the new tank PCB Quote Link to comment Share on other sites More sharing options...
Steven McGee Posted April 6, 2011 Report Share Posted April 6, 2011 I had a worn motor on my DKS 3 which would draw 14.5 v and then the mahine would cut out and switch off. With a new motor fitted the voltage range was about 11.5v with no load to about 13.0v under load. Good luck. Quote Link to comment Share on other sites More sharing options...
Wallie Posted May 9, 2011 Report Share Posted May 9, 2011 Hey Guys, I used the 12V dc wires of the Power Supply (at the back of the DKS 3) My customer had a broken tank pcb but couldn't stop his production ..... to do it this way I had no problems with the frequency of the motor (thank god) and my customer could continue his production. Also I made a on/off switch for him that he would be able to shut off his motor when he was going to sleep .....but a good alternatif for continuing production ! Best Regards, Wallie Quote Link to comment Share on other sites More sharing options...

kamal pasha Posted May 24, 2011 Author Report Share Posted May 24, 2011 500w PSU unit is good enough to solve the problem, Thamks to all for the cooperation. Quote Link to comment Share on other sites More sharing options...
