1.1.5 Safety instructions for the gantry
CAUTION
Moving the gantry can damage the placement head.
When moving the gantry, observe the following:
► NEVER move the gantry by pushing with your hands against the placement head.
1.1.6 Safety instructions on hazardous materials
CAUTION
Observe the safety data sheets
Observe the applicable safety data sheet, when handling hazardous materials (e. g. Loctite
241, ethanol).
1.1.7 Classification of the optical systems
1.1.7.1 Classification of the whole machine
Fig.1: Laser class 2
The ready-to-operate overall machine is assigned
to laser class°2.
The laser classes are determined according to
DIN EN 60825-1:2014.
1.1.7.2 Laser classification
The following modules are assigned to laser class 2:
●
Laser light barriers at the board conveyor
1.1.7.3 Classification of the camera systems
WARNING
LEDs
The camera illumination systems are fitted with light LEDs. These are assigned to risk
group 1 according to IEC 62741:2006.
► Do not look into beam!
1.2 Lock out and tag out procedure
1.2.1 Purpose and scope
Before performing any preventive maintenance work, conversion work or service work, a procedure
of locking and tagging must be followed and warning signs must be attached if not stated other-
wise. If it is not necessary to switch off the machine, it is explicitly mentioned.
The procedure, when followed, correctly eliminates the possibility of an employee being injured.
NOTICE
Additional safety measures
These procedures represent the minimum lock/tag out requirements for the machine during
preventive maintenance work and service work. Any additional safeguards needed to com-
plete work safely can be specified by facilities supervision, the safety officer, the safety
committee and the health department.

1.2 Lock out and tag out procedure
Service Manual ASM ProcessLens Dual-lane 09/2018 9
1.2.2 Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is
to be followed:
► Notify affected employees.
► Shut down the equipment. Carry out all normal stopping procedures:
– Press the Stop button.
– Switch off the ASM ProcessLens inspection software.
– Shut down the control computer.
– Switch the machine off at the main power switch.
► Isolate the machine from all its energy sources:
– Disconnect the main power connection.
► Lock out the machine:
– Attach a lock whenever possible (e.g. to the main power switch).
NOTICE
Alternatively: Tag out procedure
If a machine can be locked out, it must be. However, there are situations where energy isol-
ating devices cannot accommodate locks. In these cases, the energy isolating devices
must be tagged to warn employees that the machine is de-energized for servicing. The tag
must be securely fastened, it must be placed in a position visible to all and it may only be
removed by the person who attached it.
► Release stored energy:
Stored energy in the electrical energy in electrolytic capacitors must be released by appropri-
ate means.
– After switching off the machine, wait the specified discharge time, before the machine can
be operated again without risk.
► Verify the lock out:
Testing the lock out can be done simply by pressing the start button.
► The following steps must be taken to restore the machine to operation:
– Check the area. Authorized employees should remove all of their tools and reinstall all
guards.
– Notify all affected employees.
– Before removing even one lock or tag, inform all workers in the area that the machine is
going to be restarted.
– Remove locks/tags
– Each authorized employee must remove his or her own lock. Each authorized employee
will have his or her own lock.
– Turn the machine on. Authorized workers should observe the equipment in operation to
ensure repairs were done correctly.
1.2.3 Testing
Service personnel may test the circuits by activating them briefly without canceling the locking
method. This may be done only when no other work is being performed by any other person on the
equipment being tested.
It is extremely important that all remote start switches be tagged with the Do Not Operate tag to
prevent inadvertent operation of the equipment during these periods.

1.2.4 Responsibility and obligations
●
It shall be the responsibility of the maintenance and service personnel to make sure this pro-
cedure is adhered to.
●
It shall be the responsibility of the maintenance and service personnel’s immediate supervisor
to instruct his personnel on this procedure.
●
It shall be the responsibility of the Safety Officer with assistance from the Safety Committee,
Health Service Department, and the various managers and Vice-presidents to administer the
lock out/tag out procedure.
1.2.5 Training
●
Staff training:
– The safety regulations require training for every individual. Of course, not every employee
is exposed to the same degree of danger or is involved with lock out/tag out as others are.
So extensive training is not necessary for everyone.
– To determine how much training to provide for each worker, the employees are divided into
three groups. Each group has its own level of training.
●
Authorized employees:
– These workers actually install the locks and tags and do the preventive maintenance or
service work. So they must know the most about controlled energy. First, they must be
able to recognize all energy sources and measure the amount of energy. Authorized em-
ployees must look for energy sources out of the realm of the obvious. These energy
sources include electrical, mechanical, hydraulic, pneumatic, chemical, thermal and gravit-
ational. Once these workers can recognize all energy sources they must be taught how to
isolate, control, and release the energy without any risk.
●
Affected employees
– These are workers who operate the machinery or equipment that may be de-energized.
Other employees who may be affected include those who work in an area that contain
equipment that may be locked/tagged out. These employees have to be instructed about
the nature of the energy control program. They must know why lock out/tag out is import-
ant, what tags and locks look like and why they must not remove tags or locks.
●
All others
– As the name implies, any employee who is not affected or authorized fits into this category.
These employees include office personal, managers, and upper management. Although
they do not have a direct relationship to the machinery being locked or tagged, they have
to receive some training.
– To evaluate the lock out/tag out procedure, the safety department will conduct periodic in-
spections. As part of the inspection the safety department will document that all facets of
the procedure are followed. The safety department will follow up with formal classroom re-
view or retraining of the lock out/tag out procedure.
1.2.6 Review
This procedure will be reviewed and amended as required, and at least once a year.
