2.5.1 Safety instructions for closing the protective covers

To avoid risk of injury when closing the protective covers on the machine, the operator must in-

struct the personnel concerned to always follow the instructions below when handling the protec-

tive covers.

CAUTION

RISK OF CRUSHING HANDS

IF THE PROTECTIVE COVERS ARE NOT CLOSED CORRECTLY 2

Fig. 2.5 - 1 Safety instructions for closing the protective covers (example of SX4)

(1) Grab handles

 To open or close the protective covers, always take hold of these by the grab handles.

 When closing, do not reach into the gap between the protective cover and the machine panel.

 When closing the protective cover, make sure that the area in which it is swiveled is free of

obstruction and that no other people are at risk of injury.

2.5.2 Manual insertion of board into the input conveyor

WARNING 2

Risk of injuries to hands when manually inserting a board into the input conveyor.

– The manual insertion of the board is only permitted during the machine installation phase

(machine calibration, test placement, etc.) and may only be performed by specially qualified

personnel.

– Manual insertion of boards is expressly prohibited on any machines released for production,

as these give unprotected access to the travel range of the gantry.

– The operating company is responsible for ensuring that the input and output conveyors are

covered to prevent anyone reaching into these areas with hands or arms. All upstream and

downstream modules (screen printers, conveyors, inspection systems, ovens, etc.) must take

these same precautions.

 Observe the warning instructions when inserting boards into the input conveyor.

 Start moving the board into the conveyor with the Move Board In function on the SC GUI.

2.5.3 Safety instructions for processing capacitors based on powdered metal

There is a risk associated with processing capacitors based on powdered metal (e.g. tantalum).

The risk is that

– an exothermic reaction, i.e. a sudden build-up of heat, may occur, if these components are

damaged. If the ambient conditions are unfavorable, and depending on the capacitance, this

buildup of heat can cause damage.

– This effect can occur when these components are cut.

Please contact your suppliers to clarify whether the components that you handle are affected.

In extremely rare cases, this risk can occur in the tape cutter of SIPLACE machines, with the re-

mote possibility of causing a smoldering fire in the waste tape.

The ambient conditions are unfavorable if:

(1) The components remain on the tape while the set tape cycle is checked (since the operator

can cycle the feeder module onward without removing components during this check).

(2) The components remain on the tape, e.g. due to a tear in the cover foil.

From software version SC.706.xx Version 06/2012 EN 2.5 Safety instructions for operating the SX4/DX4 machine

(3) The components remain on the tape, and the components or tape do not conform to the spec-

ification, thus increasing the pickup error rate.

Please follow the instructions given below to minimize the risk when placing capacitors based on

powdered metal.

(1) If the component tape is cycled onward manually, the operator must remove any components

remaining in the tape pocket.

(2) If the cover foil tears, the operator must remove any components remaining on the tape.

To prevent tantalum capacitors which were not picked up from causing the tape material to burn

when it is cut, the user interface has been extended to include the option "Stop immediately on

pickup error". This option must be enabled in SIPLACE Pro. On the placement machine, the com-

ponent that was not picked up is paced forward again until it is ready for removal from the com-

ponent tape. The track is deactivated and the operator is sent an error message to remind him to

pick up the tantalum component from the tape.

PLEASE NOTE 2

A description of how the operator can manually remove those tantalum capacitors which were

not picked up can be found in section 3.9.1.3, page 148.

2.5.4 Note on the ESD safety of the machines

Only use nozzles that are identified as conductive. This is the only way to meet the requirements

for the ESD safety of the machine.

2.5.5 Safety instructions for correct use of the reject bin

Observe the following instructions to avoid risk of collision between the placement head and com-

ponent or the nozzle reject bin:

 Make sure, that the reject bin is seated correctly in its mount.

 Check that the reject bin does not project over the mount.

PLEASE NOTE 2

A sensor (see section 6.6

, page 330) which indicates the correct position of the reject bin can be

retrofitted for each reject bin.
