2.8 Disabling the compressed air supply and discharging
the pressure
The compressed air unit is located in the sector distributor of location 1 (see fig. 4.2 - 1, page 214
). The compressed air working pressure of the machine is set to 0.50 ± 0.025 MPa (5.0 ± 0.25
bar). The position of the compressed air unit is shown at item 1 in fig. 2.8 - 1
, page 104. The supply
of compressed air to the machine can be interrupted with the shutoff valve (item 2 in fig. 2.8 - 1
,
page 104
).
Use the machine key to release the cover lock.
Lift the cover (see fig. 2.8 - 1, page 104 ).
Turn the lever of the shutoff valve (item 1 of fig. 2.8 - 1, page 104) from the vertical to the
horizontal position.
Monitor the operating pressure manometer (item 5 in fig. 2.8 - 1, page 104 ). When the ma-
chine is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.

CAUTION
Interruption to compressed air supply!
When the machine is switched on, do not use the stop valve to interrupt the com-
pressed air supply for more than 30 minutes.
If you need to shut off the pneumatic system for longer in order to carry out preven-
tive maintenance or servicing work, you must switch the machine off at the main
switch and disconnect it from the power supply.

From software version 710.0 Edition 12/2016 2.9 Lock out and tag out procedure
105
2.9 Lock out and tag out procedure
2.9.1 Purpose and scope
Before performing any preventive maintenance work or service work, a procedure of locking and
tagging must be followed. The procedure, when followed correctly eliminates the possibility of an
employee being injured.
2
2.9.2 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.
– Shut down the control computer.
– Switch the machine off at the main power 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 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.
