Edition 08/2011 EN 2.12 Lock Out and Tag Out Procedure
111
2.11.1.2 Placement System Switched off at the Main Power Switch and Disconnected ...
The automatic placement system is unpowered, apart from slight residual voltages in the power
supply unit.
The SWS must be separately disconnected from the mains power supply!
2.11.1.3 Compressed Air Conditions in the Machine after Switching off at the Main
Power Switch
When switching off the main switch (item 1 of fig. 2.11 - 1) or if the main power supply to the ma-
chine fails, the electrically controlled main valve Y1 of the compressed air unit (item 1 of fig. 2.10
- 1). The pressure will drop to 0 MPa (0 bar) within 5 seconds.
2.11.2 Main switch at the SWS
Each SWS has its own main switch for the voltage supply.
2.12 Lock Out and Tag Out Procedure
CAUTION 2
The following instructions also apply to the SWS modules.
2.12.1 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.
NOTE
This process contains the minimum requirements for locking the machine or attaching warning la-
bels to the machine for maintenance or service work. Any additional safeguards needed to com-
plete work safely can be specified by facilities supervision, the safety officer, the safety committee
and the health department. 2
