 General notes

General notes
Please read this operating manual carefully before commissioning the device. The
functionality and value-retention of this steam sterilizer depends on the care accorded to
it. Please store this operating manual carefully and in close proximity to the device. It
represents a component of the product.

Symbols used
Symbol Explanation

Indicates a dangerous situation, which if not avoided, could entail slight to life-
threatening injuries.
Draws your attention to a situation, which if not avoided, could result in damage to
the practice fittings or the device.
Draws your attention to important information.

Symbols on the device

Symbol Explanation

In affixing the CE mark, the manufacturer declares that this product fulfils the basic
requirements of the EMC Directive and the Low Voltage Directive.

The symbol of the struck out waste bin identifies a device that may not be disposed
in the domestic waste. The vendor is responsible for appropriate disposal of the
device - it must be delivered to the vendor to be disposed of.
With the designation of an apparatus with this symbol, the manufacturer
furthermore declares that he satisfies all requirements of the law concerning the
release, redemption and environmentally sound disposal of electric and electronic
appliances.

Disposal
MELAG devices are synonymous for long-term quality. When you eventually need to decommission your
MELAG device, we offer a special disposal service. Simply contact your stockist.
The packaging protects the device against transport damage. The packaging materials have been
selected for their environmentally-friendly and recycling properties and can be recycled. Returning the
packaging to the material flow reduces the amount of waste and saves raw materials. Dispose of all non-
required packaging materials at the collection points of the dual system.

Safety instructions
When operating the log printer, please observe the following safety instructions as well as those contained
in subsequent chapters.

Cable and power supply

 Operate the log printer only with the power cable included in the scope of delivery.
 Liquids may not be permitted to penetrate the interior of the log printer. This could result in
electrical shocks or short circuiting.
 Only connect the log printer to those devices intended for operation with this log printer.
 Disconnect the log printer from the mains during long downtimes.
 Only operate the device with 5 volts DC.

Installation location and storage

 Setup the log printer in such a way that it is protected against strong direct sunlight and heat.
 Store and operate the log printer only in a dust-free environment protected against heat and
damp.
 Do not place the log printer directly on the steam sterilizer. The steam sterilizer will become hot
upon operation. Non-observance could result in restricted function and damage to the log printer.

Repair
 Do not open the log printer. Incorrect opening and repair can compromise electrical safety and
pose a danger to the user.
 The log printer may only be dismantled or repaired by authorized persons.

Determining the network situation and changing the computer IP address

(temporary)
To enable the MELAG device to recognise the log printer in the (practice) network, it mus be located in the
same subnetwork as the MELAG device. The factory setting of the log printer IP address is
192.168.40.240.
If this is not the case, the IP address of the label printer must be adapted as follows:
1. Where required, connect the network adapter power supply.
2. Connect the Ethernet cable to the Ethernet socket on the network adapter and connect the other
end with the computer.

PLEASE NOTE
The following instructions apply to the procedure for a Windows operating system. Should a
different operating system be installed on your computer, change the IP address (e.g.
192.168.40.100) manually in accordance with the relevant instructions.

3. Working on the computer, via Start → Control panel → Network and Internet open the →
Network and sharing centre.
4. Select LAN connection and open the Properties window (right mouse-click).
5. Working in the list Internet protocol version 4 (TCP/IP) select Properties.
6. To change the IP address of the computer, select the applicable version:
 The computer has a fixed IP address
 The computer obtains the IP address automatically:

number block is specified by the (practice) network administrator.
3. Enter the password “MELAG” under Authentication.
4. Accept the settings with [Apply configuration].

Connecting the label printer in the (practice) network:

1. Disconnect the Ethernet cable from the computer and connect the cable directly to the steam
sterilizer integrated in the network, or to a free network socket.
The IP address (e.g. 192.168.40.100) must be returned to the original IP address after configuration.

Re-establishing communication between the computer and the (practice) network:

1. Working on the computer, via Start → Control panel → Network and Internet open the →
Network and sharing centre.
2. Select LAN connection and open the Properties window (right mouse-click).
3. Working in the list Internet protocol version 4 (TCP/IP) select Properties.
4. To perform the original computer settings, select the applicable version:

Registering the log printer on the MELAG device

For MELAtherm 10 / Premium-Class / Vacuquick:
The (practice) network must be operated in the subnetwork 192.168.40.xx so that the log printer can be
recognised automatically in the MELAG device without any further settings being performed.

Proceed as follows to register and save the log printer in the MELAG device:
1. Activate the MELAG device and wait until the main menu is displayed.
2. Connect the log printer power supply to the socket.
3. Switch off the MELAG device and then on again. The MELAG device will recognise and save the
IP address of the log printer automatically.

PLEASE NOTE
Should these steps not be successful, it is probable that the IP address saved in the MELAG
device and the log printer do not belong to the same subnetwork.
 In this case, change the IP address of the log printer in the MELAG device. Consult the
technical manual of the MELAG device.

For Premium-Plus-Class / Evolution / Cliniclave Series:

The (practice) network must be operated in the subnetwork 192.168.40.xx so that the log printer can be
recognised automatically in the MELAG device without any further settings being performed.

Proceed as follows to register and save the log printer in the MELAG device:
1. Select the Settings menu.
2. Navigate to the Log printer option. The display switches to the "Log printer" window. If a log
printer has not been setup, the "IP address" and "MAC address" fields are empty.
3. Select SEARCH to display a list of all available log printers connected in the network.

5. Select the desired log printer from the list and confirm with SAVE.
6. The display returns to the "Log printer" window.

7. Press the symbol to exit the menu.

8. Then, working in the Settings menu Logging, select the log printer for the log output.

PLEASE NOTE
Should these steps not be successful, the IP address saved in the MELAG device and the
network adapter do not belong to the same subnetwork.
 Arrange for MELAG to adapt the IP address of the network adapter to the IP address of your
(practice) network. Please consult your stockist.

PLEASE NOTE
 If the log printer is connected with multiple MELAG devices, check whether the serial number
of the MELAG is correct on every log printout.

PLEASE NOTE
 Check the legibility of the log printout on an annual basis. Given reduced legibility, produce a
copy.

Setting the log printer as the output medium

Please note that you need to select the log printer MELAprint 42 as the output medium for immediate or
subsequent log output independently of registration on the respective MELAprint device. The operating
manual of the respective MELAG device shows how to set the output media on the device.

Test output
You can perform a test output to check the connection of the log printer to the MEALG device. Simply
select any log and print it. Further instructions on selecting a log are outlined in the user manual of the
respective MELAG device. How to perform a self-test: Self-test
