General information
Validity of this manual and required compliance
Contents The complete operating manual for the ALX 734, ALX 735 and ALX 736 print dispens-
ers consists of the following parts:
• Operating manual (for operating personnel)
• Installation manual (for service personnel)
• Service manual (for service personnel)

Notes on installation and repair work
General information Before performing any maintenance or repair work:
Block access to the working area of the machine to unauthorised persons.
Post a notification sign, which calls attention to the work.
Electro-static discharge:
When the casing is open, protect the electronics from damage due to electro-static
discharge, e.g. wear an anti-static arm band.
Tools:
Only use suitable tools.
Ensure all tools are at hand before beginning the work.
Do not attempt to improvise or to use improper tools, e.g. loosening an interior-
toothed screw (Torx) with a hexagon socket driver.
Rubber and plastic parts:
Do not allow hoses, seals, and other rubber or plastic parts to come into contact
with grease, petrol, benzene, kerosene or mineral oil.
Environmental
protection
Avoid unnecessary waste, e.g. use cleaning cloths sparingly and reuse packing
material.
Only store operating materials, such as fresh or used cleaning agents, in suitable
containers. Never allow them to enter the sewerage system or to seep into the ground.
Do not put old batteries, removed parts, and used cleaning agents in household
waste. Dispose of them in an eco-friendly manner.
Packaging materials:
Only recyclable materials are used for packaging the machine.
Dispose of unwanted packaging material in an eco-friendly manner.
Eco-friendly disposal:
Sort the waste as much as possible, e.g. separate metals from plastics.
Avoid contaminating the waste if possible.
Drop off the waste at the collection points provided for that purpose
or
Have the waste collected by suitable recycling agencies.
Use any on-site options.
Observe all relevant rules, ordinances, and laws.

Rules for electromag-
netic compatibility Connect all metallic parts to each other via large surfaces, ensuring electric
conductivity.
Only polished metal surfaces are electrically conductive. Painted or oxidised sur-
faces are unsuitable. Aluminium which appears to be polished still has an invisible
oxidation layer on the surface.
Coated or plated surfaces, though electrically conductive, can reach very high re-
sistance values at high frequencies (skin effect).
Clean contact surfaces, polish the metal, use fan disks (washers) or mounting
plates.
Carry out EMC grounding, preferably as a neutral (star) point. A neutral (star)
point prevents loops.
When laying the signal lines and power cable, space them apart.
Lay all control and signal lines at least 50 cm distant from power cables (e.g. mo-
tor line). Minimum distance in the switch cabinet: 20 cm.
Spatially lay out all the lines in the switch cabinet as close as possible to the refe-
rence potential.
Lead the signal lines into the unit or switch cabinet from one side only.
The more lines that are laid in front and in back between the switch cabinet and the
machine, the larger the radiation surface of the radiated electromagnetic energy.
Lead the signal lines out of the machine (in one bundle and from one location, if
possible) and into the switch cabinet.
Twist together unshielded lines from the same circuit.
This reduces interference effects of various kinds.
Wire inductive components to suitable interference suppressors.
Possible inductive components: Relay, solenoid valve
Possible interference suppressors: Diodes, varistors, RC combinations
House all components suspected of being sources of RF interference fields in a
closed metal casing (Faraday screen).
Shield all signal and control lines.
Ground the shielding on both sides at its large surfaces.
For insufficient potential equalisation between the shielding lines: Lay an additio-
nal equalisation lead parallel to the shielding with a cross section at least 10 mm2.
Avoid equalisation currents in the shielding of the signal lines
Equalisation currents can arise between subassemblies with different grounding
conditions.
When the grounding conditions are different, only shield the side with the better
grounding condition.
Only shield both sides when the grounding conditions are the same (e.g. inside a
machine).
Power filter
Mount the power filter direct at the power supply.
Connect the filter casing to the EMC grounding via large metal surfaces.

Lay all lines as close as possible to metal parts, even reserve cables
Freely hanging lines act as transceiver antennas.
Ground all reserve cables and unused wires in the cables at least at one end.
Keep the cables as short as possible
Cable resistance and signal distortion increase with the length of the cable.

After all servicing or repair work
Safe operation
Protect against injuries that can result from electrical current
WARNING!
Danger of crushing between dispenser edge and applicator pressure plate due to
applicator movement !
Prevent personnel from reaching between dispensing edge and applicator by
installing higher-level protective guards a.
a) Movable, separating guards according to EN 953
WARNING!
Risk of an accident due to moving or loose parts!
Re-install all covers and safety equipment.
Check for firm seating of all screw connections that were loosened during the
work.
Remove all tools and other aids used during service and repair from the working
area of the labeller.
Verify flawless functioning of all safety equipment.
WARNING!
This unit operates at mains voltage! Coming into contact with electrically live com-
ponents can cause potentially lethal electrical shocks and burns.
After assembling, check the printer according to the regulations relevant in your
country.
WARNING!
Contact with energised components can result in life-endangering currents through
the body as well as burns. The label dispenser is connected with the mains supply!
Only allow work on the electronics system to be done by authorised electronics
technicians.
Observe the following information unconditionally.
Power connection: The machine side power connector has a definite phase position.
Pay attention to the phase position when connecting the machine.

Protection against injuries that can result from mechanical actions
Before any repair work: Detach the machine from power supply.
Check to ensure it is de-energised.
Secure the power supply against unintentional or unauthorised switch-on.
Casing: Before opening the casing and before removing the PMA(printer) module or the
LMA(dispenser) module, pull the power plug.
The casing may only be opened by trained personnel and when the machine is de-
energised.
Only put the machine into operation when the rear housing is correctly in place and
when the PMA module and the LMA module are correctly installed.
If the machine must be
switched on while the
casing is open for
repair or inspection:
Never touch energised components. This also applies to components with low
voltages.
Ensure the flawless
condition of the
electrical system:
Regularly check the electrical equipment.
Only connect the machine to other machines if these meet the requirements for a
SELV circuit, in accordance with EN 60950.
Re-tighten loose connections.
Immediately replace damaged lines.
After assembling, check the printer according to the regulations relevant in your
country.
WARNING!
Acute risk of injury and long-term bodily injury from working with heavy loads!
Lift or carry the machine with a minimum of 2 persons. If possible, use a crane
or other lifting device.
Only use suitable and defect-free restraining devices during transportation and
installation.
Never allow the machine to stand with loosened mounting brackets, not even for
a short time.
If the machine is fastened to a movable support: Ensure it can not tip over.
WARNING!
Risk of accident due to uncontrolled machine start-up!
Before doing any repair work, switch off the machine.
