2.7 Disabling the compressed air supply and discharging
the pressure
The compressed air unit is located on the back of the SWS (see fig. 2.7 - 1, page 56 ). The com-
pressed air working pressure of the SWS is set to 0.50 ± 0.025 MPa (5.0 ± 0.25 bar).

WARNING
Risk of injuries!
Risk of injuries from pressurized compressed air lines. The compressed air supply to the
SWS is made available by the SIPLACE CA4 V2.
Switch the compressed air off at the SIPLACE CA4 V2.
NEVER detach compressed air lines while they are still pressurized.

2.8 Locking the SIPLACE Wafer System and attaching
warning labels
2.8.1 Purpose and scope
Before performing any preventive maintenance work or service work on the SIPLACE Wafer Sys-
tem, a procedure of locking and tagging must be followed. The procedure, when followed correctly
eliminates the possibility of an employee being injured.
2
2.8.2 Description
Whenever it becomes necessary to isolate, control and release energy for the SIPLACE Wafer
System, the following procedure must be followed
Notify affected employees.
Switch off the SIPLACE Wafer System and any auxiliary devices. Carry out all normal stop-
ping procedures:
– Shut down the SIPLACE Wafer System.
– Switch off the SIPLACE Wafer System at the main switch.
Disconnect the SIPLACE Wafer System from all its energy sources:
– Switch off the compressed air at the SIPLACE CA4 V2, thereby interrupting the supply
of compressed air to the SIPLACE Wafer System.
– Interrupt the power supply to the SIPLACE Wafer System.
Lock out the machine.
– Attach a lock whenever possible (e.g. to the main switch).
PLEASE NOTE
Minimum requirements
These procedures represent the minimum lock/tag out requirements for the preventive
maintenance or 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.

Alternatively: Tag out procedure
If a machine can be locked out, it must be. However, there are situations where energy iso-
lating 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. 2
Release stored energy
Stored energy in the compressed air supply or electrical energy in electrolytic capacitors must
be released by appropriate means. 2
After switching off the SIPLACE Wafer System, wait the specified discharge or pressure
unloading time, before the SIPLACE Wafer System can be operated again without risk.
Verify the lock out.
Test the SIPLACE Wafer System lock.
The following steps must be taken to restore the SIPLACE Wafer System 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 on the SIPLACE Wafer System and the SIPLACE CA4 V2. Authorized workers
should observe the equipment in operation to ensure repairs were done correctly.
2.8.3 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.
