From software version SR.605.xx 07/2008 EN Edition 2.9 Energy state of the machine after switching off at the main power switch
79
The following table specifies the voltages of modules when the machine is switched off at the main
switch, but still connected to the mains supply.

2.9.2 Machine switched off at the main power switch and disconnected
The machine is unpowered, apart from slight residual voltages in the power supply unit.
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) 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
). 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 for the preventive mainte-
nance or service work. Any additional safeguards needed to complete work safely can be speci-
fied 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 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.
