Operating Manual XCx 300 / 500 / 540 Version 09/08
1Safety-related Information
The term automation system as used in this manual includes control
units, their components (modules), other parts (such as racks, cables),
operator panels, and the software used for programming,
commissioning and operating the control units. This operating manual
can only describe a fraction of the automation system (e.g. modules).
The technical design of SCHLEICHER automation systems is based
on the EN 61131-2 (IEC 61131-2) product norm. The systems and
devices have CE marking according to the EMC directive 89/336/EEC
and, if applicable, the low-voltage directive 73/23/EEC.
The machinery directive 89/392/EEC is not applicable, because the
safety objectives of the directive are covered by the low-voltage and
EMC directives.
When SCHLEICHER automation systems are part of the electrical
equipment of a machine, the manufacturer must include them in the
conformity evaluation process. In this case the DIN EN 60204-1 norm
must be observed (safety of machines, general requirements for
electrical equipment of machines).
When an automation system is properly maintained and used for its
intended purpose it will not normally cause damage to property or
present health hazards. However, improper configuration, installation,
maintenance or operation of the system or machine, ignoring the
instructions in this manual, or intervention by insufficiently qualified
personnel may result in connected actuators (such as motors,
hydraulic units, etc.) becoming a source of danger.
1.1 Correct Use of the System
SCHLEICHER automation systems are state-of-the-art products and
manufactured to recognised safety requirements. All the same, their
use can cause danger to the health and safety of operators and others,
or damage machines, systems or other property.
The automation system must only be used in perfect technical
condition for its intended purpose, with attention given to safety and
danger, and observing the operating manual. Correct transport,
storage, installation, operation and maintenance of the system are all
prerequisites for smooth and safe operation of the control system.
Malfunctions, in particular those which may affect safety, must be
immediately resolved.
Automation systems are designed exclusively to control machines and
systems. Automation systems are not intended for any other use than
the above. The manufacturer will therefore accept no liability for any
damages resulting from the incorrect use of the systems.
When using automation systems, all instructions given in this manual
regarding mechanical and electrical setup, commissioning and operation
must be observed.

1.2 Selection and Qualification of Personnel
Important!
All configuring, programming, installation,
commissioning, operation and maintenance work on the
automation system must be carried out by trained
personnel such as electricians or electrical engineers.
Personnel responsible for configuring and programming
the system must be familiar with all safety-related issues
in automation technology.
System operators must be instructed on the operation of
the control system and be familiar with the relevant
operating instructions.
All personnel responsible for installing, commissioning
and maintaining the system must have had appropriate
training qualifying them to work on automation systems.
1.3 Configuring, Programming, Installation, Commissioning and Operation
The automation system will in most cases be a part of a larger system
in which machines are controlled. When configuring, installing and
commissioning automation systems to control machines the machine
manufacturer and the user must observe the safetyregulations as
defined in the machinery directive 89/392/EWG. For specific applications
national accident prevention regulations such as VBG 4.0 will apply.
Safety-related components on the controlled machine must be
designed such that they operate independently from the control
system. Emergency stop components must be operational in all control
modes. In an emergency stop the power supply to all switching
elements controlled by the control system must be cut off.
Measures must be taken for restarting an interrupted control program
following voltage dips or power failures. Operating conditions should
never cause danger, not even for a short time. In the event of danger
the emergency stop must be immediately triggered.
In order to prevent an open-circuit in the signal circuit causing non-
controllable conditions in the control system, the relevant hardware and
software safety precautions must be taken for I/O interfacing. Control
elements and their assigned control panel elements must be installed
in a place where they are sufficiently protected against inadvertent
use.
1.4 High Voltages
Warning!
When the cabinet is opened or casing is removed from
system components certain parts of the automation
system are exposed. These parts may be subject to
dangerous high voltages.
The user must prevent any unauthorised and incorrect access to the
system (for example, by ensuring that the cabinet is locked).
Personnel must be familiar with all sources of danger and measures for
commissioning and maintaining the system in line with the instructions
given in this manual.

Safety-related Information
10
Operating Manual XCx 300 / 500 / 540 Version 09/08
1.5 Maintenance Measuring and testing on active devices must be carried out in
accordance with the regulations and instructions of the VBG 4.0
accident prevention regulation. The appropriate power tools must be
used.
Repairs on control components must be carried out at repair shops
authorised by SCHLEICHER. Opening the components and repairs by
unauthorised personnel may lead to personal injury or damage to
property.
Always be disconnected the device from the mains before opening it
(either disconnect the mains plug or use the cut-out switch).
Control modules may only be replaced when the power is switched
off. Disassembly and assembly must be carried out according to the
directives for mechanical assembly.
Fuses may only be replaced with those types specified in Technical
Data.
Batteries mayonly be replaced with those types specified in Technical
Data. Batteries must always be disposed as hazardous waste.
1.6 Dealing With Used Batteries
When the batteries in the automation system are dead they must be
disposed of in a battery return system or through public waste
disposal facilities.
Batteries should be fully discharged before disposal. A battery is
discharged when the function of the device is impaired due to
insufficient battery capacity.
When batteries for disposal are not fully discharged precautions must
be taken to prevent short circuits. For example by sticking tape over
the poles of the battery.

3.1 XCx The XCx must be installed in earthed and closed metal cases (e.g.
enclosures or cabinets) on an electrically conductive metal carrier
board.
Note
To protect the devices against electrostatic discharge,
operating personnel must discharge any electrostatic
charge they may be carrying before opening enclosures or
cabinets.
3.1.1 Installation position The XCx can be installed in any position.

3.1.3 Fixing the XCx to DIN rail
Use DIN rail type TS 35 mm / 7.5 to DIN EN 50022.
The DIN rail must be attached with a good electrical connection to an
electrically conducting carrier board.
DIN rail installation is sufficient for normal mechanical
loads.
For higher mechanical loads please refer to "Fixing
with screws" (only XCx 500 and XCx 540.
Assembly

3.1.4 Fixing with screws
Only XCx 500 and XCx 540 are suitable for fixing with
screws.
The controller must be attached with a good electrical connection to
an electrically conducting carrier board.
Use 4 M4 machine screws with toothed lock washers.
The fixing holes for fixing with screws are on the left and right sides of
the base plate of the device. They are easily accessible from outside.
