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.
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 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 prevention,
}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-related
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 func-
tions 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 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 expansion module provides additional inputs and dual-pole semiconductor outputs.
The function of the inputs and outputs on the control system depends on the user program
created using the PNOZmulti Configurator. The user program is downloaded from the
PNOZmulti Configurator 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 control system, plus connection examples.
4.2.1 Inputs
The expansion module provides 8 inputs.
Features
}Each input can be used to evaluate run monitoring for press applications.
}Each input can be configured for pulse detection for run monitoring.
– The pulse width has to be a least 1 ms for reliable pulse detection.
– When pulse detection is active, the functions pulse suppression and detection of
shorts across contacts are deactivated via the test pulses.
}In PNOZmulti Configurator the pulse suppression time can be changed for the inputs. A
change of the preset pulse suppression time (see Technical details [ 22]) can be
used to suppress the self-monitored outputs and for interference suppression.
}For detection of shorts across contacts of the inputs:
– In the main program the inputs can be connected with the test pulses of the base unit.
– In the module program the inputs can be connected to the test pulses of the expan-
sion module.

4.2.2 2-pole outputs
The expansion module provides two dual-pole outputs.
Features:
}Signals at the output
– "0" signal (0V) at the output (O+/O-):
Output is high impedance
No current to the load
– "1" signal (+24V) at the output (O+/O-):
Output is low impedance
Current is supplied to the load
}The max. capacity at an output depends on the load (see drawing on the max. capacitive
load). Connecting a higher capacity may lead to an error.
}Operation with electronic contactors has not been tested and may lead to errors. Please
contact our Customer Support team if you are using electronic contactors.
}Open circuit detection
}Cannot be used as a single-pole output
Output tests
The following output tests are carried out:
}Asymmetric test in error-free operation
– In this test, one output transistor is switched on and the other switched off for the test
duration t1 as a maximum. The load is not switched on because of the test. If errors
are detected during this test, then an advanced on test is run.
– The test duration t1 is max. 5 ms.
– The repetition time between the asymmetrical tests t2 is at least 30 s.
– The time t3 between two asymmetrical tests O+ and O- is at least 1 s.
}Advanced on test in the event of an error
– The advanced on test is always run directly after an asymmetric test, in which an er-
ror has occurred. It is used to determine the cause of the error.
– The test is run for the test duration t1 as a maximum
– The test duration t1 is max. 5 ms.
– The test enables precise error diagnostics
– The load must not switch on because of the test.
– The following errors are detected:
Shorts across contacts (external error),
Short circuits and interruptions on the transistors,
Short circuits and open circuit on the connected load

5.1 General installation guidelines
}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 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 ele-
ment (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.
}The ambient temperature of the PNOZmulti units in the control cabinet must not exceed
the figure stated in the technical details. Air conditioning may otherwise be required.
