` Muting function
` Max. 8 expansion modules and 1
fieldbus module can be connected
` LED indicator for:
– Diagnostics
– Supply voltage
– Output circuits
– Input circuits
` Test pulse outputs used to detect
shorts across the inputs
` Monitors shorts between the safety
outputs
` Plug-in connection terminals (either
cage clamp terminal or screw terminal)
Chip card
Chip cards are available with memories of 8 kByte and 32 kByte. For largescale projects we recommend the 32
kByte chip card (see chapter containing the order references).
The chip card with a memory of 32
kByte can only be used from
PNOZ m1p Version 2.0.
Safety features
The relay conforms to the following
safety criteria:
` The circuit is redundant with built-in
self-monitoring.
` The safety function remains effec-
tive in the case of a component failure.
` The relay contacts meet the re-
quirements for safe separation
through increased insulation compared with all other circuits in the
safety system.
` The safety outputs are tested peri-
odically using a disconnection test.
Unit description
The PNOZmulti modular safety system
is used for the safety-related interruption of safety circuits and is designed
for use in:
` Emergency stop equipment
` Safety circuits in accordance with
VDE 0113 Part 1 and EN 60204-1

Function description
The function of the inputs and outputs
on the safety system depends on the
safety circuit created using the
PNOZmulti Configurator. A chip card
is used to download the safety circuit
Wiring
The wiring is defined in the circuit diagram in the Configurator. There you
can select the inputs that are to perform a particular safety function and
the outputs that will switch this safety
function.
Please note:
` Information given in the "Technical
details" must be followed.
` Outputs:
– O0 to O5 are safety outputs.
– O4 and O5 are relay outputs
– O0 to O3 are semiconductor out-
puts
– OA0 is an auxiliary output.
` To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).
` Use copper wire that can withstand
75 °C.
` Sufficient fuse protection must be
provided on all output contacts with
inductive loads.
` Power for the safety system and in-
put circuits must always be provided from a single power supply. The
power supply must meet the regulations for extra low voltages with
safe separation.
` Two connection terminals are avail-
able for each of the supply connections 24 V and 0 V (semiconductor
outputs), plus A1 and A2 (power
supply). This means that the supply
voltage can be looped through several connections. The current at
each terminal may not exceed 9 A.
` 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.
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.
` Test pulse outputs are also used to
supply safety mats that trigger a
short circuit.
Where test pulses are used for the
safety mat, they may not be reused
for other purposes.
Safety mats are supported from
Version 4.3 of the base unit.
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.
