85
2.9.2 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.
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. Any additional 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
Æ Notify affected employees.
Æ Shut down the equipment. Carry out all normal stopping procedures:
– Press the Stop button.
– Shut down the station computer.
– Switch the placement machine off at the main power switch.
