2.11.1.2 Machine Switched off at Main Switch and Disconnected From Power
The machine 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 you switch off the main switch (item 1 in fig. 2.11 - 1, page ) or if the power supply to the
machine fails, the electrically controlled main valve Y1 of the compressed air unit will be closed
(item 1 in 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
2
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.
2
2.12.2 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 the machine, including the SWS.
– Attach a lock whenever possible, e.g. to the motor contactor.
CAUTION
The following instructions also apply to the SWS modules.
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.
