2.7 Disabling the compressed air supply and discharging

the pressure

The compressed air unit is at location 2 (see fig. 4.4 - 1, page 166). The compressed air working

pressure of the placement machine is set to 0.51 ± 0.01 MPa (5.1 ± 0.1 bar). The position of the

compressed air unit is shown at item 1 in fig. 2.7 - 1

, page 88. The supply of compressed air to

the placement machine can be interrupted with the shutoff valve (item 2 in fig. 2.7 - 1

, page 88).

 Use the placement machine key to release the cover lock.

 Lift the cover (see fig. 2.7 - 1, page 88).

 Turn the lever of the shutoff valve (item 1 of fig. 2.7 - 1, page 88) from the vertical to the hor-

izontal position.

 Monitor the operating pressure manometer (item 5 in fig. 2.7 - 1, page 88). When the place-

ment machine is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.

CAUTION

Interruption to compressed air supply!

 When the placement machine is switched on, do not use the stop valve to interrupt

the compressed air supply for more than 30 minutes.

 If you need to shut off the pneumatic system for longer in order to carry out preven-

tive maintenance or servicing work, you must switch the placement machine off at

the main switch and disconnect it from the power supply.

2.8 Locking and attaching the warning labels

2.8.1 Purpose and scope

Before performing any preventive maintenance work or service work to the placement machine,

a procedure of locking and tagging must be followed. The following procedure, when followed cor-

rectly, eliminates the possibility of an employee being injured by electrical shock in connection with

unexpected movement.

2.8.2 Description

Whenever it becomes necessary to isolate, control and release energy for the placement ma-

chine, the following procedure is to be followed.

 Notify affected employees.

 Switch off the placement machine and any auxiliary devices. 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 placement 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 main switch).

WARNING

Risk of injuries!

Risk of injuries from pressurized compressed air lines.

 NEVER detach compressed air lines while they are still pressurized.

PLEASE NOTE

Minimum requirements

These procedures represent the minimum lock/tag out requirements for the preventive

maintenance or service work on the placement machine. Any additional safeguards

needed to complete work safely can be specified by facilities supervision, the safety of-

ficer, the safety committee and the health department.
