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 Process Lens PL 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 isolating
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 appropriate
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 pre-
vent 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 proced-
ure 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 ser-
vice 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 employees must
look for energy sources out of the realm of the obvious. These energy sources include elec-
trical, mechanical, hydraulic, pneumatic, chemical, thermal and gravitational. 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 important, 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 review 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.

1.3 Other instructions
1.3.1 Environmentally-friendly disposal of materials and components
Our products are manufactured using only materials and parts that can be easily separated and dis-
posed of in an environmentally-friendly way.
NOTICE
Observe the applicable regulations
The company operating the system has sole responsibility for the proper, environmentally-friendly dis-
posal of machines, working materials, consumable materials and wear parts.
► Please observe your national statutory provisions for waste disposal and environmental protec-
tion.
1.3.2 Use of original accessories and spare parts
Only use original spare parts and authorized accessories. The use of other parts will affect safety and
will invalidate the liability for any consequential damage.
1.3.3 Information about this service manual
WARNING
Additional qualifications required
The service work described in this manual may only be performed by specially trained service techni-
cians, with appropriate qualifications and expertise.
If you should have any questions during the service work, please contact the customer hotline directly
or send an e-mail.
1.3.4 ESD guidelines
1.3.4.1 What does ESD mean?
Fig.2: ESD label
Almost all of the modules in use today are equipped with highly integ-
rated Metal-Oxide-Semiconductor (MOS) blocks and components. The
manufacturing techniques used mean that these electronic components
are extremely sensitive to overvoltage and thus to electrostatic dis-
charge.
The abbreviation for such modules is "ESD" (Electrostatic Sensitive
Device). "ESD" is used internationally. The following symbol on cabinet
rating plates, racks or packaging indicates that components which are
sensitive to electrostatic discharge have been used and thus that the
modules concerned are also touch-sensitive.
ESDs can be destroyed by voltages and power levels that are far below the level that can be per-
ceived by humans. Such voltages occur if a person touches a component or module without earthing
themselves. Components that are exposed to such overvoltage do not generally appear to be defect-
ive immediately - incorrect behavior starts after the component or module has been in operation for
some time.
1.3.4.2 Important measures to protect against static charging
► Most plastics can easily become charged and must therefore be kept away from at-risk compon-
ents.
► Always ensure that people, the workplace and packaging are safely earthed when handling elec-
trostatic sensitive components.
