8.3 Cleaning Cycle The following is an example of a typical cleaning cycle Drain steps are performed after each rinse or wash phase The final rinse and subsequent drain steps can be repeated until desired final rinse conductivity levels are met • Rinse • Chemical #1 Wash • Rinse • Chemical #2 Wash • Rinse • Final Rinse • Heated Drying (Requires Dryer System option) • Cooling (Requires Dryer System option) All steps are setup as individual operation codes (Opcodes) enabling full customization of cleaning cycles Cycle times are dependent upon many factors such as part type, soil load, available utilities, and drying requirements 8.4 System Automation Sani-Matic provides all programming of the HMI and PLC, enabling automation of the provided system For additional custom system automation (eg, Custom HMI Screens, Additional Security Levels, External System Communications), see the System Automation options • Cleaning sequences will be automatically controlled using wash cycle recipes • Up to (40) different recipes can be stored in the PLC • Each recipe has its own setpoint values (eg, time, temperature, conductivity) which are adjustable • Up to (96) individual steps per recipe • Each step in the recipe is composed of Operation Codes (Opcodes) which define the phase of the wash cycle (eg, caustic wash, final rinse) Opcodes can be arranged, omitted, or duplicated within the recipe as needed • Up to (96) unique Opcodes • Measured process variables have alarms with adjustable high/low setpoint values • Up to (96) different setpoint values (eg, time, temperature, conductivity) • The operator will have the ability to initiate, monitor and edit (with correct security level) the wash cycle, recipes, and setpoint values via the HMI • (3) HMI security levels are included • HMI User security is setup for local users If desired, Active Directory User Authentication can be setup by the facility in which the system is installed 8.5 Automation Interfaces The standard system allows for two (2) 24V DC digital output signals for water fill, as well as two (2) 24V DC digital output signals for chemical addition The signals are used to activate external equipment (eg, zero-static block valve) for water fill and chemical addition cycle steps The cabinet washer system monitors and alarms these incoming utilities as required
