SEQUENTIAL LOGIC CONTROLLER - 11607 Multi-program electroniccontoller For a professional solution to your washingneeds - Easy adaptable to any technical and func-tional innovation in washing system- Cost-effective operation, energy savingand concumption optimization- Fully programmable without using program-ming tools and languages

Technical data Description Application Supply voltage The ELD is a programmable controller com-prising a front panel mounting control unit (CPU) and a drive unit (Power) assembled in- side the machine.The two units are connoc- ted via a 10-pole flat cable. Washing programs can be configured or mo- dified directly from the control panel or PC. Special pressure and temperature sensors al- low users to read and configure the washing water level and temperature. A special self-test programme continually con- trols the device and promptly displays mes- sages to indicate any machine anomaly. Various safety features are also provided to prtect the machne from erroneous configura- tion.Programs may be stored on memory cards and then transferred to other machines or to floppy disks. Messages can be displayed in 5 languages. • Industrial washing machines• Cloth ashing systems • Stone wash systems • Metal wash systems 24, 115, 230 Vac;50 and 60 Hz Supply tolerance ±10% Power consumption 10 VA

This level lets user programme several basic sequences for the machine (machine cycles), for example:Washing 1, Rinse 3;Spin 7, etc.Level B:also intended for end users, to link different machine cycles for requires washing program- mes.
