 6 Description

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 energy-
efficient 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 anti-
crush 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.

 Description 7

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

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.

 Preventive maintenance 5

Door
Check that the door seal closes tight and is undamaged and that there is no leakage while a
program is running. Clean or replace the seal if necessary.

Detergent dosing
Check that the suction hose and pump are full of detergent or rinse-aid before running a
program. When the pre-programmed amount of detergent is changed, the consumption must be
checked with a measuring glass.

Washing system

All supply lines must be closed when working on the pipe system.

• Check that the washing arms can rotate freely.

• Check that the holes in the washing arms are not blocked. Clean when necessary.
• Check that the coarse strainer in the bottom of the washing chamber is correctly installed.
Clean when necessary.
• Check that all couplings connecting the washing system to the pump and chamber are
leaktight. Tighten and seal if necessary.

Temperature check
• Check the temperature during a program run. Compare time and temperature with the program
sheet. Time and temperature are especially important in the disinfection phase.
The measuring equipment must be capable of registering temperature and time continuously.
High-performance equipment is essential for reliable measuring results, because of the
relatively rapid temperature changes.
Only one measuring point in the centre of the machine is need for the function check.

Note:
Washer-disinfectors that have been shown not to meet the requirements in terms
of temperature, sequence, washing system and safety must not be used until the
faults have been corrected.

Error codes

P02 OP-D
F00 POWER FAIL

Fault codes indicate that a serious fault has occurred in the washing process. The fault must be
put right by an authorised service technician.

Acknowledging a fault code

Reset the fault code by:
1. pressing U. The alarm signal is silenced.
2. correcting the fault.
3. The machine is still locked but the current process has been aborted. Pressing U again
drains liquid from the machine and the dirty side door goes down.

Note:
If the draining pump is faulty, the water is not drained from the machine.

NOTE:
The goods in the machine are not clean. Start a new process.

Conductivity measurement (extra equipment)

Conductivity is measured with equipment from Endress+Hauser.

This must only be done by authorised personnel.

Function in washing process

The conductivity meter monitors the quality of the water in the final rinse, independently of the
process control.
If the conductivity at the end of the final rinse is higher than the preset value, the machine is
drained with the Emptying 2 phase, ie the machine is drained while at the same time being
supplied with DW/WFI water and the final rinse is repeated automatically.
If, after three repetitions, the conductivity is still above the preset value, the process is stopped
and fault code 11 appears on the display.

Measuring range
The normal measuring range is 0-20 µ S/ cm

Calibration
See under Calibration

Removing a measuring cell

For easy access to the measuring cell, slacken the two screws that keep the electrical cabinet in
place. Remove the right-hand screw. Move the electrical cabinet to the left and rotate it forward.
Unscrew the measuring cell. The cables are long enough to allow the measuring cell to be
immersed in a vessel of calibration liquid.

Booster tank

The booster tank contains hot water. This may cause scalding
injuries if proper procedures are not followed.

It is essential to drain the booster tank when servicing the booster

tank and its valves. This is in order to prevent scalding, since the
temperature of the water in the booster tank is about 85 degrees
Celsius (about 180 degrees F)

Booster tank with drain tap

The tank is drained via a drain tap on the back of the tank. Make sure that the
tap is not open before unscrewing the plug. If a nipple with G ¼ male thread is
used, the associated hose can be fitted to the drain tap. The tank can now be
drained.
After draining, check that the drain tap is working properly. Seal the plug with
PTFE tape and refit it.
The microswitch must be checked as well, since it activates the booster tank.
The booster tank heating must never be on when the door(s) is/are down for
loading/unloading goods.
When servicing is complete, check the entire system for water leaks.
The booster tank must be filled before a process is started. To do this, open the
DW valve via the control system. This is important, in order to avoid unwanted
fault codes when starting the machine.
