Service Manual Process Lens PL - 03/2025 5
1 Introduction
This service guide is a manual or reference work for performing service work on the Process Lens PL
machine.
For additional information, please also observe the instructions on the 0198022 Instruction Guide if
necessary.
1.1 Safety instructions
DANGER
Nonobservance of these safety instructions may cause injury to personnel and damage to the
machine!
► Please observe the safety instructions in the user manual of the relevant machine for all
work!
1.1.1 Conventions for the use of safety instructions and symbols
Safety instructions
This manual contains notes that must be observed to guarantee your personal safety and to avoid
damage to equipment. These notes are highlighted by warning triangles and are indicated as follows
according to the level of risk:
DANGER
Definition
For the purposes of this manual, this indicates that fatal or severe injuries or considerable damage to
property will occur if this hazard warning is not observed.
WARNING
Definition
For the purposes of this manual, this indicates that fatal or severe injuries or considerable damage to
equipment may occur if these warning instructions are not followed.
CAUTION
Definition
For the purposes of this manual, this indicates that minor injuries or damage to property may occur if
this caution is not observed.
NOTICE
Definition
For the purposes of this manual, this note provides information about the product or indicates a part
of the manual that requires particular attention.
1.1.2 Safety instructions for working with strong magnetic fields
DANGER
Strong permanent magnetic fields
Fatal hazard: persons with active implants (e.g. pacemakers, defibrillators, insulin pumps, etc.) are at
risk from strong permanent magnetic fields inside the machine.
Persons at risk should avoid the immediate vicinity of the machine.

CAUTION
Danger of crushing
Danger of crushing for persons with passive metal implants (e.g. plates, screws).
► Do not reach or lean over into the machine when the covers are open.
► Do not bring any metal objects into the danger area.
CAUTION
Strong permanent magnetic fields
There is a risk that the strong magnetic fields could corrupt data on data media or check cards.
► Keep sensitive data media away from the permanent magnets.
1.1.3 Safety instructions for the power supply (without SMPS)
DANGER
The system is electrically driven. When electrical devices are in use, certain parts carry dan-
gerous voltage levels
There is a risk of death, severe injury and/or considerable damage to equipment if these instructions
are not followed.
► Switch off the main switch and disconnect the Process Lens PL solder paste inspection machine
from the power supply before carrying out any work on live components.
●
This means that some parts of the system carry potentially lethal voltages - even when switched
off at the main power switch.
●
Incorrect handling of the solder paste inspection system can therefore result in fatal injuries,
severe injuries or considerable damage to equipment.
●
Measurements and maintenance work must always be carried out by appropriately qualified per-
sonnel.
●
Always follow the applicable accident prevention and DIN regulations (particularly DIN EN 60
204, part 1) or the regulations specific to your country.
●
Before starting any maintenance work, switch the machine off at the main switch and disconnect
it from the main power supply.
●
Always secure the machine against unauthorized reactivation. If these instructions are not
followed, you may be able to touch live parts, which could result in fatal or severe injuries.
Maintaining, Installing or Removing Assemblies
► End all inspection operations on the machine.
► Shut down the Windows operating system correctly, otherwise problems may occur when
restarting or data may be lost.
► Switch the machine off at the main switch.
► Disconnect the machine from the main power supply.
► Switch off the machine and attach warnings signs to indicate that service work is in progress.

1.1.4 Residual voltages and discharge times in the machine
1.1.4.1 Energy state of the machine after the EMERGENCY STOP button is pressed
If the EMERGENCY STOP button is pressed, the voltage are reduced to harmless residual voltages in
a very short time.
WARNING
Some parts of the system carry potentially lethal voltages
The machine is supplied with 1/N/PE ~ 240, 50/60 Hz mains voltage. This means that some parts of
the system carry potentially lethal voltages - even when switched off at the main power switch. Incor-
rect handling of the machine can therefore result in death or severe injury or considerable damage to
equipment.
► Always follow the applicable accident prevention and safety regulations (particularly DIN EN
60204, part 1 or IEC 60204, part 1) and the safety regulations in your own country.
► The covers over the power supply unit may ONLY be opened by appropriately qualified and
trained personnel.

1.1.4.2 Energy state of the machine after switching off the main power switch
WARNING
Some parts of the system carry potentially lethal voltages
The machine is supplied with 1/N/PE ~ 240, 50/60 Hz mains voltage. This means that some parts of
the system carry potentially lethal voltages - even when switched off at the main power switch. Incor-
rect handling of the machine can therefore result in death or severe injury or considerable damage to
equipment.
► Always follow the applicable accident prevention and safety regulations (particularly DIN EN
60204, part 1 or IEC 60204, part 1) and the safety regulations in your own country.
The following components still carry potentially lethal voltages even if the main power switch is
switched off:
●
Mains connection terminals of the main power switch.
NOTICE
Process Lens PL electrical diagrams
For details, please refer to the Process Lens PL electrical diagrams.
To avoid losing data, assess the following criteria before switching off your machine (apart from in
emergencies):
●
Has the machine finished transmitting machine and recipe data?
●
Has the machine finished processing the PCB?
●
Has the machine software completed the shot-down phase?
Machine switched off at the main power switch and disconnected
The machine is unpowered, apart from slight residual voltages in the power supply unit.
