3 Safety
3.1 Intended use
The expansion module may only be connected to a base unit from the PNOZmulti system
(please refer to the document "PNOZmulti System Expansion" for details of the base units
that can be connected).
The configurable small control systems PNOZmulti are used for the safety-related interrup-
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 module can be used in furnaces. If the module's relay outputs shut down the entire fuel
supply and the furnace is used in continuous operation, appropriate external measures
must be used to establish diversity of the shutdown elements (requirement of EN 50156-1).
For example, an appropriate measure may be an additional, monitored switching element
(contactor or relay), which is controlled by a safe semiconductor output and is switched in
series with both relay outputs.
Alternatively the expansion module PNOZ mo5p can be used.
The coated version of the product PNOZ mo4p is suitable for use where there are in-
creased environmental requirements (see Technical details [ 20]).
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 [ 20]).
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.

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 relay contacts meet the requirements for protective separation through increased in-
sulation compared with all other circuits in the safety system.
4.2 Functions
The expansion module provides additional relay outputs.
The function of the outputs on the safety system depends on the safety circuit created us-
ing 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 locking elements on the rear of the unit to attach it to a mounting rail. Connect
the control 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 devices in the control cabinet must not exceed the figure
stated in the technical details. Air conditioning may otherwise be required.
}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.

6.4 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 in the PNOZmulti Configurator and downloaded back into the base unit.
Proceed as described in the operating manual for the base unit.
NOTICE
For the commissioning and after every user program change, you must
check whether the safety devices are functioning correctly.

Operation

7 Operation
When the supply voltage is switched on, the PNOZmulti copies the configuration from the
chip card.
The PNOZmulti system is ready for operation when the "POWER" and "RUN" LEDs on the
base unit are lit continuously.

7.2 Function test of the relay outputs
When the relay outputs are switched on, the mechanical contact on the relay cannot be
tested automatically. Depending on the operational environment, measures to detect the
non-opening of switching elements may be required under some circumstances.
When the product is used in accordance with the European Machinery Directive, a check
must be carried out to ensure that the safety contacts on the relay outputs open correctly.
Start the device again or open the safety contacts (switch off output), so that the internal
diagnostics can check the correct opening of the safety contacts
}for SIL CL 3/PL e at least 1x per month
}for SIL CL 2/PL d at least 1x per year
