NOTICE
Laser class 1 and 1M
Modules in laser classes 1 and 1M are not labeled.
All installed camera systems and the whole machine (when ready for oper
-
ation) are assigned to laser class 1.
The laser classes are determined according to DIN EN 60825-1:2001.
The following camera systems are assigned to laser class 1:
▪ Stationary component cameras for the SIPLACE TwinStar (TwinHead)
and the SIPLACE Multistar (CPP)
▪ Component camera, stationary, P&P, type 33, 55 x 45, digital
▪ Component camera, stationary, P&P, type 25, 16 x 16, digital
▪ Component camera, stationary, P&P, type 36, 32 x 32, digital
Do not look directly at this with optical instruments!
The following camera systems are assigned to laser class 1M:
▪ CO camera C&P, type 23, 6 x 6 on the SpeedStar
▪ CO camera C&P, type 41, 6 x 6 on the SpeedStar
▪ CO camera C&P, type 30, 27 x 27 on the MultiStar
▪ CO camera C&P, type 30, 18 x 18 on the 12-segment Collect&Place
head
Laser radiation
Do not look into beam!
The following modules are assigned to laser class 2:
▪ PCB barcode scanner
▪ Component sensor on the SpeedStar
▪ Component sensor on the MultiStar
The entire machine is classified as laser class 2 if the coplanarity laser mod
-
ule option is installed.

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 otherwise. 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.
Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is to be
followed.
► Notify affected employees.
► Switch off the machine and all additional devices. Carry out all normal stopping procedures:
⇨ Press the STOP button.
⇨ Shut down the station computer.
⇨ Switch the machine off at the main switch.
► Isolate the machine from all its energy sources:
⇨ Shut off the compressed air supply.
⇨ Shut off the main power supply.
► Lock out the machine.
⇨ Attach a lock wherever possible (e.g. to the main power switch or the motor contactor).
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 complete
work safely can be specified by facilities supervision, the safety officer, the safety committee
and the health department.
Example: attaching a padlock to the motor contactor
► Turn the operating lever (1) counterclockwise.
► Use the screwdriver to push the locking lug (2) out of
the operating lever (1).
► Secure the operating lever with a padlock (3).

► Alternative: attaching warning signs
If a machine can be locked, 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 or label must be securely fas
-
tened, it must be placed in a position visible to all and it may only be removed by the person who
attached it.
► Release of stored energy:
Stored energy in the compressed air supply or electrical energy in electrolytic capacitors must be
released by appropriate means.
⇨ After switching off the machine, wait until the voltages and the compressed air have discharged,
so that work can be performed without any risk.
► Testing the lock out:
The lock can be easily tested by pressing the START button.
► The following steps must be taken to restore the machine to operation.
► Check the working area. Authorized employees should remove all of their tools and reinstall all safety
features.
► Notify all affected employees.
► Before removing even one lock or tag, inform all workers in the affected area that the machine is
going to be restarted.
► Remove locks/tags
► Every authorized employee must remove his own lock and shut it away.
► Turn the machine on. Make sure that authorized staff check the equipment in operation to ensure
that repairs were performed correctly
Testing
Service personnel may test circuits by energizing them briefly without suspending the Lock Out / Tag
Out Procedure. This may only be done 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.
Responsibilities
▪ It shall be the responsibility of the maintenance and service personnel to make sure this procedure
is adhered to.
▪ It shall be the responsibility of the maintenance and service personnel's immediate supervisor to in
-
struct 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.
