details of which versions of the PNOZmulti Configurator can be used for this product.
3.3 Safety regulations
3.3.1 Safety assessment
Before using a device it is necessary to perform a safety assessment in accordance with
the Machinery Directive.

Safety
Operating Manual PNOZ m B0
1002660-EN-07 11
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.
3.3.2 Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by competent persons.
A competent person is a qualified and knowledgeable person who, because of their train-
ing, experience and current professional activity, has the specialist knowledge required. To
be able to inspect, assess and operate devices, systems and machines, the person has to
be informed of the state of the art and the applicable national, European and international
laws, directives and standards.
It is the company’s responsibility only to employ personnel who
}Are familiar with the basic regulations concerning health and safety / accident preven-
tion,
}Have read and understood the information provided in the section entitled Safety
}Have a good knowledge of the generic and specialist standards applicable to the spe-
cific application.
3.3.3 Warranty and liability
All claims to warranty and liability will be rendered invalid if
}The product was used contrary to the purpose for which it is intended,
}Damage can be attributed to not having followed the guidelines in the manual,
}Operating personnel are not suitably qualified,
}Any type of modification has been made (e.g. exchanging components on the PCB
boards, soldering work etc.).
3.3.4 Disposal
}In safety-related applications, please comply with the mission time TM in the safety-re-
lated characteristic data.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).
3.3.5 For your safety
The device meets all the necessary conditions for safe operation. However, you should al-
ways ensure that the following safety requirements are met:
}This operating manual only describes the basic functions of the device. Advanced func-
tions are described in the online help for the PNOZmulti Configurator, in the
"PNOZmulti Communication Interfaces" document and in "PNOZmulti Special Applica-
tions". Only use these functions once you have read and understood the documenta-
tion.
}You must note the information stated in the PNOZmulti Safety Manual.

Safety
Operating Manual PNOZ m B0
1002660-EN-07 12
}Adequate protection must be provided for all inductive consumers.
}Do not open the housing or make any unauthorised modifications.
}Please make sure you shut down the supply voltage when performing maintenance
work (e.g. exchanging contactors).

4 Function description
4.1 Integrated protection mechanisms
The relay meets the following safety requirements:
}The circuit is redundant with built-in self-monitoring.
}The safety device remains effective in the case of a component failure.
}The safety outputs are tested periodically using a disconnection test.
4.2 Functions
The function of the inputs and outputs on the control system depends on the safety circuit
created using the PNOZmulti Configurator. A chip card is used to download the safety cir-
cuit to the base unit. The base unit has 2 microcontrollers that monitor each other. They
evaluate the input circuits on the base unit and expansion modules and switch the outputs
on the base unit and expansion modules accordingly.
The LEDs on the base unit and expansion modules indicate the status of the configurable
control system PNOZmulti.
The online help on the PNOZmulti Configurator contains descriptions of the operating
modes and all the functions of the control system, plus connection examples.
4.3 System reaction time
Calculation of the maximum reaction time between an input switching off and a linked out-
put in the system switching off is described in the document "PNOZmulti System Expan-
sion".

5 Installation
5.1 Control cabinet installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Install the system vertically on to a horizontal mounting rail. The venting slots must face
upward and downward. Other mounting positions could damage the safety system.
}Use the locking elements on the rear of the unit to attach it to a mounting rail.
}In environments exposed to heavy vibration, the unit should be secured using a fixing
element (e.g. retaining bracket or end angle).
}Open the locking slide before lifting the unit from the mounting rail.
}To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
NOTICE
Damage due to electrostatic discharge!
Electrostatic discharge can damage components. Ensure against discharge
before touching the product, e.g. by touching an earthed, conductive sur-
face or by wearing an earthed armband.
5.1.1 Mounting distances
With control cabinet installation it is essential to maintain a certain distance from the top
and bottom, as well as to other heat-producing devices (see diagram). The values stated
for the mounting distances are minimum specifications.
The ambient temperature in the control cabinet must not exceed the figure stated in the
technical details. Air conditioning may otherwise be required.

5.4 Connecting the base unit and expansion modules
The position of the expansion modules is defined in the PNOZmulti Configurator. The ex-
pansion modules are connected to the left or right of the base unit, depending on the type.
Please refer to the document "PNOZmulti System Expansion" for details of the number of
modules that can be connected to the base unit and the module types.
The modules are linked via jumpers.
}Remove the terminator on the side of the base unit and on the expansion module.
}Install the base unit and expansion modules on the mounting rail in the order configured
in the PNOZmulti Configurator and connect the units using the jumper supplied.
}Fit the terminator to the unconnected interfaces on the base unit and expansion mod-
ule.

6.1 General wiring guidelines
The wiring is defined in the circuit diagram in the Configurator. There you can select the in-
puts that are to perform a safety function and the outputs that are to switch this safety func-
tion.
Please note:
}Information given in the Technical details [ 32] must be followed.
}Outputs O0 to O3 are semiconductor outputs
}Use copper wiring with a temperature stability of 75 °C.
}Sufficient fuse protection must be provided on all output contacts with inductive loads.
}The safety system and input circuits must always be supplied by a single power supply.
The power supply must meet the regulations for extra low voltages with protective sep-
aration.
}Test pulse outputs must exclusively be used to test the inputs. They must not be used
to drive loads.
Do not route the test pulse lines together with actuator cables within an unprotected
multicore cable.
6.2 Commissioning the control system
Procedure:
}Wire the inputs and outputs on the base unit in accordance with the circuit diagram.
}Connect the supply voltage:
– Supply voltage for the control system:
– Terminal A1: + 24VDC
– Terminal A2: 0 V
– Supply voltage for the semiconductor outputs:
– 24 V terminal: + 24VDC
– 0V terminal: 0 V
Please note: The supply voltage for the semiconductor outputs must always be present,
even if you are not using the semiconductor outputs.
When the voltages are fed separately using two power supplies, the supply voltage for the
control system and the supply voltage for the semiconductor outputs are galvanically isol-
ated.
CAUTION!
Do not connect or disconnect expansion modules and terminators during
operation.
