Function description
][Funktionen_ein_zweikanalig _ohne Quer
Single-channel operation: no re-
dundancy in the input circuit, earth
faults in the reset circuit and input
circuit are detected.
Dual-channel operation without de-
tection of shorts across contacts:
redundant input circuit, detects
– earth faults in the reset and input
circuit,
– short circuits in the input circuit
and, with a monitored reset, in
the reset circuit too.

Wiring
][Verdrahtung_Si_unverz
Please note:
Information given in the “Technical
details” must be followed.
Outputs 13-14, 23-24 are safety
contacts.
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical de-
tails).
Calculation of the max. cable runs
lmax in the input circuit:
Rlmax = max. overall cable resist-
ance (see technical details)
Rl /km = cable resistance/km
Use copper wire that can withstand
60/75 °C.
Sufficient fuse protection must be
provided on all output contacts with
capacitive and inductive loads.

Installation
][Montage_PNOZsigma
Install base unit without contact ex-
pander module:
Ensure that the plug terminator is
inserted at the side of the unit.
Connect base unit and PNOZsigma
contact expander module:
Remove the plug terminator at the
side of the base unit and at the con-
tact expander module.
Connect the base unit and the con-
tact expander module to the sup-
plied connector before mounting
the units to the DIN rail.
Installation in control cabinet
The safety relay should be installed
in a control cabinet with a protec-
tion type of at least IP54.
Use the notch on the rear of the unit
to attach it to a DIN rail (35 mm).
When installed vertically: Secure
the unit by using a fixing element
(e.g. retaining brakket or end angle).
Push the unit upwards or down-
wards before lifting it from the DIN
rail.

Service life graph
Lebensdauerkurve_Relais_Text vor Kurve
The service life graphs indicate the
number of cycles from which failures
due to wear must be expected. The
wear is mainly caused by the electrical
load; the mechanical load is negligible.

Example
Inductive load: 0,2 A
Utilisation category: AC15
Contact service life: 2,000,000 cy-
cles
Provided the application requires few-
er than 2,000,000 cycles, the PFH val-
ue (see technical details) can be used
in the calculation.
To increase the service life, sufficient
spark suppression must be provided
on all output contacts. With capacitive
loads, any power surges that occur
must be noted. With contactors, use
freewheel diodes for spark suppres-
sion. Technical details PNOZsigma

Si-Kennzahlen_Zusatz_Relais_Lebensdauer_PDB
It is essential to consider the relay's
service life graphs. The relay outputs'
safety-related characteristic data is
only valid if the values in the service life
graphs are met.
The PFH value depends on the switch-
ing frequency and the load on the relay
output.
If the service life graphs are not acces-
sible, the stated PFH value can be
used irrespective of the switching fre-
quency and the load, as the PFH value
already considers the relay's B10d val-
ue as well as the failure rates of the
other components.
Si_Kennzahlen_Erläuterung_1
All the units used within a safety function must be considered when calculating the safety characteristic data.

INFORMATION
A safety function's SIL/PL values are
not identical to the SIL/PL values of
the units that are used and may be dif-
ferent. We recommend that you use
