The PLC System is operated via a Touch Screen Interface. The programme which operates the Suite has three security levels, as follows:-

Level One
Operator access, allowing the operator to select a pre-determined recipe entering his/her name and batch details. When the operator has completed vacuum loading, the remainder of the operation is automatic.

Level 2
This level is to validate new products and enter all the parameters of the system to be saved as a fixed recipe, by selecting the following:-

A. Open Recipe

The open recipe allows the technician to look at each individual operation of the system giving full control allowing the PLC to log all of the data.

B. Modifying a Recipe

When validating a similar product a fixed recipe can be selected and modified to be saved as another.

Level 3
This level is for the use of the maintenance department allowing the engineer to select manual control to test and service the system.
