tion of safety circuits and are designed for use in:
}E-STOP equipment
}Safety circuits in accordance with VDE0113 Part 1 and EN60204-1
The coated version of the product PNOZ mi1p is suitable for use where there are increased
environmental requirements (see Technical details [ 16]).
The following is deemed improper use in particular:
}Any component, technical or electrical modification to the product
}Use of the product outside the areas described in this manual
}Use of the product outside the technical details (see Technical details [ 16]).
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product
may cause interference if installed in other environments. If installed in other
environments, measures should be taken to comply with the applicable
standards and directives for the respective installation site with regard to in-
terference.
3.2 System requirements
Please refer to the "Product Modifications PNOZmulti" document in the "Version overview"
section for details of which versions of the base unit and PNOZmulti Configurator can be
used for this product.
3.3 Safety regulations
3.3.1 Safety assessment
Before using a unit it is necessary to perform a safety assessment in accordance with the
Machinery Directive.
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.

Safety
Operating Manual PNOZ mi1p
20880-EN-06 9
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 someone who, because of their training, experience and current pro-
fessional activity, has the specialist knowledge required to test, assess and operate the
work equipment, devices, systems, plant and machinery in accordance with the general
standards and guidelines for safety technology.
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 this description under "Safety"
}And have a good knowledge of the generic and specialist standards applicable to the
specific 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 unit meets all the necessary conditions for safe operation. However, you should always
ensure that the following safety requirements are met:
}This operating manual only describes the basic functions of the unit. The expanded
functions are described in the PNOZmulti Configurator's online help. Only use these
functions once you have read and understood the documentations.
}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 conforms to the following safety criteria:
}The circuit is redundant with built-in self-monitoring.
}The safety function remains effective in the case of a component failure.
4.2 Functions
The expansion module provides additional inputs.
The function of the inputs on the safety system depends on the safety circuit created using
the PNOZmulti Configurator. A chip card is used to download the safety circuit 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 online help on the PNOZmulti Configurator contains descriptions of the operating
modes and all the functions of the PNOZmulti safety 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 General installation guidelines
}The control system should be installed in a control cabinet with a protection type of at
least IP54. Fit the control system to a horizontal mounting rail. The venting slots must
face upward and downward. Other mounting positions could destroy the control system.
}Use the notches on the rear of the unit to attach it to a mounting rail. Connect the con-
trol system to the mounting rail in an upright position, so that the earthing springs on the
control system are pressed on to the mounting rail.
}The ambient temperature of the PNOZmulti units in the control cabinet must not exceed
the figure stated in the technical details, otherwise air conditioning will be required.
}To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
CAUTION!
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.

5.3 Connecting the base unit and expansion modules
Connect the base unit and the expansion modules as described in the operating manuals
for the base modules.
}The terminator must be fitted to the last expansion module
}Install the expansion module in the position configured in the PNOZmulti Configurator.
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.

Commissioning

6 Commissioning
6.1 General wiring guidelines
The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
}Information given in the Technical details [ 16] must be followed.
}Use copper wire that can withstand 75°C.
}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.
6.2 Preparing for operation
The N/C contact on the trigger element (e.g. E-STOP) must be connected to the input cir-
cuit. A short circuit in the input circuit may or may not be detected, depending on the config-
uration and wiring. The test pulse outputs on the base unit must be used to detect shorts
across contacts. The input assignment is defined in the PNOZmulti Configurator.
The input circuit should be connected as described in the table. The wiring at I0 and I1 is il-
lustrated as an example; inputs I2 ... 17 are wired in a similar way.

6.5 Download modified project to the PNOZmulti system
As soon as an additional expansion module has been connected to the system, the project
must be amended using the PNOZmulti Configurator. Proceed as described in the operat-
ing instructions for the base unit.
NOTICE
For the commissioning and after every program change, you must check
whether the safety devices are functioning correctly.

Operation
Operating Manual PNOZ mi1p
20880-EN-06 15
7 Operation
When the supply voltage is switched on, the PNOZmulti safety system copies the configur-
ation from the chip card.
The LEDs “POWER”, “DIAG”, “FAULT”, “IFAULT” and “OFAULT” will light up on the base
unit.
The PNOZmulti safety system is ready for operation when the "POWER" and "RUN" LEDs
on the base unit are lit continuously.
Status indicators:
}I0 ... I7 lights: Safety input I0 ... I7 carries a high signal.
}I0 ... I7 does not light: Safety input I0 ... I7 carries a low signal.
