6 Modular PCB conveyor system
NOTE
Before dismantling motors, light barriers etc. make sure that the problem is not due to poor con-
nections. For connection details please see Section 6.16 and Section 6.17.
6.1 Introduction
The modular PCB conveyor system is used for both the HS-60 and S-27 HM. This service manual
applies to both machine types. The differences between the two machines are mentioned in the
relevant Sections of this manual.
CAUTION
This service manual contains item numbers for the individual spare parts applicable to both the
HS-60 and the S-27 HM. These are for general reference only. When identifying and ordering
spare parts, you should always use the current version of the spare parts catalog for the machine
concerned.
6.2 Safety instructions
DANGER
For all procedures, please observe the safety instructions described in Chapter 2.
CAUTION
Customers must not undo any screws secured with loctite.

DANGER
The machines in the SIPLACE family operate on 3 x 400 V +/- 10%, 50/60 Hz mains voltage.
Consequently, portions of the system carry dangerous high voltage. Inside the machine base this
is true even when the main switch is switched off.
For all work in the vicinity of the PCB conveyor, the machine must be turned off and discon-
nected from the mains. In addition, the compressed air inlet on the main valve of the com-
pressed air unit in the machine base must be turned off and air must be bled from the
compressed air lines by actuating the needle valve. Make sure you have properly secured the ma-
chine so that it can not be restarted by unauthorized personnel!
During assembly and disassembly of PCB conveyor components and the lifting table, there is a
greater danger of injury through pinching, crushing or cutting off a body member, even when
the machine is turned off!
During assembly and disassembly of conveyor components there is also a risk of unhealthy pos-
ture due to the physical positioning and the weight of these components.
Two people must be available for some of these jobs.
Always wear strong protective gloves when removing or installing the PCB conveyor!
When a dual conveyor is involved, there is a risk of having a body member pinched or crushed
between the fixed side of conveyor 1 and the movable side of conveyor 2 when the conveyors are
traveling at maximum width.
If the pneumatic cutter is removed to improve accessibility, you must also comply with the safety
instructions in the chapter „Cutter, pneumatic....“ in the service manual.
There is additional, higher risk of accident when working with the SITEST program.
As a basic rule, the SITEST program may only be started by personnel who have been trained
in its use at Siemens AG and are therefore authorized to do so!
The cutter must always be completely installed for work with the SITEST program and the com-
ponent changeover table must be moved in and correctly connected.
Only authorized personnel are to have access to the key for the key-operated switch. As a final
step, this switch must always be locked (= normal operation) and the key must be locked away.

6.5 Function
6.5.1 General
The standard machine is equipped as a single PCB conveyor. A dual PCB conveyor system is
optionally available. Depending on individual requirements, either the left or right conveyor side
can be selected as the fixed conveyor side.
During placement, the PCB is clamped in place from underneath.The gap between the upper side
of the PCB and the placement head is not dependent on the thickness of the PCB and therefore
remains constant. This has the following benefits:
