AC9-2 Checkweigher Controller

The controller option provides a high security solution for existing and new user of Thermo Scientific AC9 checkweighers. This new, unique, solution for the food industry ensures that unauthorized users do not make changes to the operational settings of the checkweigher. It further enhances the performance of the checkweigher and its ability to protect your brand.

 
 
 
 
The Thermo Scientific AC9 Checkweigher Controller is a state-of-the-art instrument for the measurement and control of packaged weights in the food, pharmaceutical, and consumer industries. The new high security variant of the AC9 addresses one of the outstanding operational issues within these industries. No matter what the performance of a particular checkweigher, the operational efficiency can be greatly impaired, or even negated, by unauthorized changes to its setup.

Thermo Scientific recognizes these issues and has developed the AC9-2 variant to protect its checkweighers from unauthorized operation. Based on work in the pharmaceutical industry to meet the stringent FDA requirements for 21 CFR Part 11, the unit requires an authorized user to enter a unique user ID and passcode. Without this electronic signature a user can interrogate the checkweigher information but is unable to make operational changes to the unit.

The system administrators for the checkweigher have various options at their command, which lets them determine how the security system will operate. They can also determine which level of access is available to each authorized user.

Greater security means better brand protection and higher quality standards for the user. For customers who require a full audit trail on their checkweighers, the option to incorporate the full functionality of FDA 21 CFR Part 11 is available.

The AC9 checkweigher controller is a twin microprocessor design, which allows advanced and extensive user interface functions, and at the same time, provides consistent high performance weighing. The user interface is based on standard PC architecture, incorporating an Intel? 486 processor and color LCD screen. A dedicated 16-bit microprocessor performs the real-time weighing function and controls the I/O activity. The controller can weigh up to 900 packages per minute when connected to the appropriate weighframe. The new high security variant provides superior operator security reducing the likelihood of expensive equipment malfunction.
