2.10 Lock out and tag out procedure From software version SR.605.xx 07/2008 EN Edition

2.9.3 Compressed air conditions in the machine after switching off at the main
power switch
When the system is switched off at the main power switch (item 1 in Fig. 2.9 - 1, page 91) or if the
power supply fails, the electrically-controlled main valve Y1 of the compressed air unit closes (item
1 in Fig. 2.8 - 1
, page 90). The pressure will drop to 0 MPa (0 bar) within 5 seconds.
2.10 Lock out and tag out procedure
2.10.1 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.
PLEASE NOTE These procedures represent the minimum lock/tag out requirements. Any addi-
tional safeguards needed to complete work safely can be specified by facilities supervision, the
safety officer, the safety committee and the health department. 2
2.10.2 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 placement 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 motor contactor.
