Description
This section describes the PACS 300 control and monitoring system. PACS 300 is an electronic
system that is used to control the various functions of the washer-disinfector. The letters
PACS stand for Programmable Autoclave Control System.
The purpose of the control system is to issue orders and send them to the executive
components of the washer-disinfector so that a number of process steps can be performed in
accordance with a predetermined template. The order signals are worked out by the computer
program of the control unit in conjunction with measurements of actual parameter values for the
current program. These are usually times, temperatures and pressures.
Several different pieces of equipment can be connected to the control unit for programming,
monitoring and documenting the disinfection processes.
The operator communicates with the control unit via a control panel or an ordinary PC.
All operator panels can be used to monitor the processes, since they display all the set
parameter values as well as actual values on request. All relevant data associated with a given
process, such as batch number, operator number, date, etc., can be entered by the operator.
Programs, system definitions and process data can be documented by connecting a printer to
the unit. A host computer can also be connected directly to the CPU of the control system.
When the need arises, a measuring and monitoring system entirely independent of the control
system, can be set up by connecting a PACS SUPERVISOR system, consisting of CPU,
operator panel and connections to the control unit CPU. The measurements of the
SUPERVISOR are made by its own separate temperature and pressure sensors.
The computer contains programs for automatic calibration of the temperature and pressure
sensors. Where alternative correction constants are known, they can be entered manually. The
testing functions include means of activating analog and digital outputs and for monitoring
analog and digital inputs.
