Each value of the data can be measured and / or calculated in real time and continuously by appropriate means of said installation and compared with a predetermined value. In the example described below, the characteristic data of the cleaning fluid contamination will be expressed in number of plant operating cycles still called cleaning cycles.
  • This data will be measured at by means of a counter incrementing after each cycle of cleaning in such a way that when it reaches a value predetermined cycles, it stops the installation. he can also be expected, in simpler versions of the installation, whether the data is measured by a sensor such as, for example, a sensor for measuring the level of cleaning fluid in the rinsing reserve 11 which, when it detects a fluid level value of predetermined cleaning in reserve 11, emits a signal which causes the shutdown of said installation. Once this stop signal issued, it is mandatory to a new installation of cleaning fluid.
  • This new set up will mean in the most case simple by replacing the barrel 3 for storing the fluid cleaning so as to fill the rinsing reserve 11 with a new cleaning fluid and carry out the washing and rinsing operations with a clean cleaning fluid.
  • a system is judged by some to be insufficiently coercive towards the user. Indeed, the user can reuse the even was to carry out new operations of cleaning. In this case, the solvent, recovered after these new washing and rinsing operations, will particularly soiled.

  • Line 9 consists of coded data to control and report either actions not in accordance with use normal machine, such as organ opening shutter 5 during an operating cycle, removal of the storage drum 3 during a cycle either to report faults.
  • the manufacturer of solvent must have a computer reading system and writing electronic chips to charge the data from preset files and to collect information stored for analysis. These information should allow the solvent manufacturer to carry out a rapid and reliable reprocessing of said solvent, this has a lower cost.
  • the data extracted from a data carrier 16 by the read / write 15 integrated in the control and command, is coupled with data identifying the data carrier 16, that is to say of the smart card, to prevent the substitution of a data medium 16 by another data medium as long as the number of predetermined wash cycles is not reached. From this done, when the user has set up a keg 3 of cleaning liquid storage in the installation, if subsequently decides to replace this keg 3 with another keg, he can only do this from the moment the credit of the data carrier 16 will have been completely exhausted. As this was clarified above in the content of the chip there sensors may be provided to specify to the manufacturer of resolve incidents encountered during a certain number of operating cycles.
