Function description
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.
}The safety outputs are tested periodically using a disconnection test.
Operation
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
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 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.
System reaction time
Calculation of the maximum reaction time between an input switching off and a linked
output in the system switching off is described in the document "System Expansion".

Installation
Operating Manual PNOZ m B0
1002660-EN-02 14
Installation
Install base unit without expansion module
Make sure that the terminators are inserted on the top left and right of the unit.
Control cabinet installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Fit the safety system to a horizontal mounting rail. The venting slots must face upwards
and downwards. Other mounting positions could destroy the safety system.
}Use the locking slide 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
connection to the control cabinet housing.
ATTENTION!
Damage due to electrostatic discharge!
Electrostatic discharge can damage components. Ensure against discharge
before touching the product, e.g. by touching an earthed, conductive surface
or by wearing an earthed armband.

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 of the product in the control cabinet must not exceed the figure
stated in the technical details, otherwise air conditioning will be required.
Mounting distances:

Information
Please note that at the stated minimum distance, it will be difficult to swap
the chip card from above. If you cannot leave a greater distance, remove
the unit from the mounting rail to swap the chip card.
Connecting the base unit and expansion modules
Please refer to the document "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 and connect the units
using the jumper supplied
}Fit the terminator to the unconnected interfaces on the base unit and expansion mod-
ule.
ATTENTION!
Only connect the base unit and expansion modules when the supply voltage
is switched off.

General wiring guidelines
The wiring is defined in the circuit diagram in the Configurator. There you can select the
inputs that are to perform a safety function and the outputs that are to switch this safety
function.
Note:
}Information given in the "Technical details" must be followed.
}Outputs O0 to O3 are semiconductor outputs
}Use copper wire that can withstand 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 safe separation.
}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.
Function test during commissioning
ATTENTION!
It is essential to check that the safety devices operate correctly
– after the chip card has been exchanged
– after a project has been downloaded
– when the project has been deleted from the base unit's memory
("Reset Project" menu)
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
isolated.
ATTENTION!
Do not connect or disconnect expansion modules and terminators during
operation.
Load project from chip card
Procedure:
}Insert the chip card containing the current project into the card slot on the base unit.
}Switch on the supply voltage. The LC display shows the project name, CRC sum and
the date the project was created. Please check this information.
}Load the project by pressing the rotary knob. For the project to be downloaded, the
rotary knob must be held down for between 3 and 8 seconds. Once the project has
been successfully downloaded, the status of the inputs and outputs will be shown on
the display.
Load project via USB port
Procedure:
}Insert a chip card into the card slot on the base unit.
}Connect the computer containing the PNOZmulti Configurator to the base unit via the
USB port.
}Switch on the supply voltage.
} Download the project (see PNOZmulti Configurator's online help).
}Once the project has been successfully downloaded, the status of the inputs and
outputs and the supply voltage will be shown on the display. The "RUN" LED will be lit.
