Safe and simple
The disinfector is controlled by a microprocessor. This has several advantages:
• the built-in service program makes troubleshooting and servicing far easier
• safety and reliability can be kept high by continuous monitoring of the process
• the dosing of detergent, the temperature and the disinfection time can all be altered with great precision to suit different conditions.
The programs can be adapted precisely to suit the needs of each user. Existing programs can be re-programmed via a PC. As standard, the washer-disinfector has two to six programs.
The door and wash chamber are well insulated, so that the washer-desinfector is energy­efficient and silent in operation.
Operation is simple and the control buttons and few and clearly marked.
Programming may only be done by authorised personnel.
Simple service and installation
Valves and electrical equipment are easily accessible from the front for inspection and service.
Door function
The washer-disinfector can be fitted with a single door or double doors. All doors are of the vertical sliding type.
The doors can be motorised for automatic opening and closing. The doors have efficient anti­crush protection.
Machines with double doors have a system of interlocks to ensure that only one door can be opened at a time. This means that the clean-side door must be closed and locked by pressing the W button before the dirty-side door can be opened.
When V is pressed, the door is locked and a yellow lamp flashes (process running) for about 10 seconds. If V is pressed again during this “cancel time”, the dirty-side door is unlocked and the door can be opened manually or alternatively it opens automatically.
The doors can be locked an unlocked individually from the service program (authorisation required).
Manually-operated door
When the door is closed manually and V is pressed, the door is clocked automatically, the yellow lamp flashes and the program starts.
When the program is complete, a green lamp lights up on both sides (if there are double doors) and the clean-side door is unlocked. When the door has been opened manually, the green lamp goes out. With double doors, the clean-side door must be closed manually and locked by pressing the W button before the dirty-side door can be unlocked.
A manually-closed door can be opened by pressing the U button for about five seconds. Press U to unlock the door.

Automatically-operated door
WhenVis pressed, the door is locked, the yellow lamp flashes and the program starts.
When the program is complete, a green lamp lights up on both sides (if there are double doors) and the clean-side door opens automatically. When the door is fully open the green lamp goes out on both sides. With double doors, the clean-side door must be closed and locked by pressing the W button before the dirty-side door opens automatically.
An automatically-operated door can be closed on the dirty side without starting a process. Press and hold U for about five seconds. The door is closed and locked automatically. Press U to unlock the door.
Dosing system
In standard form, the machine has two different dosing systems. One is for alkaline detergent and one is for rinse-aid or acid detergent. The dosing amount can be set individually for each program.
The machine cannot be started until detergent has been dispensed. If the detergent holder is empty “DOS 1-4 Low level” appears on the display.
A third and a fourth dosing system for heat-sensitive goods or instrument milk, for example, can be installed.
Dosing pumps for:
1 Alkaline detergent 2 Rinse-aid or neutralisation 3 Instrument milk or enzyme agent (option) 4 Chemical disinfection (option)

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.
