Installation
Before installation, read and understand the operating manual
provided with the product.
-
Mount the relay in a safe location, away from heat sources and
vibration. -
Connect the power supply according to the specified voltage
range (24 VDC or 48-240 VAC/DC). -
Connect the safety devices (emergency stop, safety gates, light
curtains, etc.) to the appropriate input terminals. -
Connect the output terminals to the control elements
(contactors, motor starters, etc.) that need to be monitored. -
Check all wiring for correct connections and insulation.
Usage
Before using the relay, make sure that all safety devices are
properly connected and functioning correctly. Follow these steps
for safe operation:
-
Apply power to the relay within the specified voltage
range. -
The relay will perform a self-test and check for any faults or
errors. -
If no errors are detected, the status indicator will show a
green light and the relay is ready for operation. -
If an error is detected, the error indicator will show a red
light and the relay will not operate until the error is
resolved. -
When a safety device is activated, the relay will immediately
interrupt the control circuit and stop the machine or system. -
After the safety device is released, the relay will reset
itself and allow the control circuit to be re-energized.

Installation
Install base unit without contact expansion module: } Ensure that the plug
terminator is inserted at the side of the unit.
Connect base unit and PNOZsigma contact expansion module: } Remove the plug
terminator at the side of the base unit and at the contact expansion
module. } Connect the base unit and the contact expansion module to the
supplied connector be-
fore mounting the units to the DIN rail.
Installation in control cabinet } The safety relay should be installed in a
control cabinet with a protection 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 bracket or end angle).
} Push the device upwards or downwards before lifting it from the DIN rail.
Wiring
Please note: } Information given in the “Technical details [ 22]” must be
followed. } Outputs 13-14, 23-24, 33-34 are safety contacts; output 41-42 is
an auxiliary contact (e.g.
for display). } Auxiliary contact 41-42 and semiconductor output Y32 should
not be used for safety cir-
cuits! } To prevent contact welding, a fuse should be connected before the
output contacts (see
Technical details [ 22]). } Calculation of the max. cable length lmax in the
input circuit:
Rlmax I= max Rl / km
Rlmax = max. overall cable resistance (see Technical details [ 22]) Rl / km =
cable resistance/km } Use copper wiring with a temperature stability of 75 °C.
} To prevent EMC interferences (particularly common-mode interferences) the
measures described in EN 60204-1 must be executed. This includes the separate
routing of cables of the control circuits (input, start and feedback loop)
from other cables for energy transmission or the shielding of cables, for
example. } Adequate protection must be provided on all output contacts with
capacitive and inductive loads. } With UB 48 240 VAC/DC: Connect S21 to the
functional earth. } When connecting magnetically operated, reed proximity
switches, ensure that the max. peak inrush current (on the input circuit) does
not overload the proximity switch. } On 24 VDC devices: The power supply must
comply with the regulations for extra low voltages with protective electrical
separation (SELV, PELV) in accordance with VDE 0100, Part 410.
NOTICE If you connect contact expansion modules to a base unit with a
universal power supply, you will need to limit the conventional thermal
current at the contact expansion modules’ safety contacts to 70 % of the
stated current (see technical details for contact expansion module).

Preparing for operation
Operating modes The operating mode is set via the rotary switch on the unit.
You can do this by opening the cover on the front of the unit.
NOTICE Do not adjust the rotary switch during operation, otherwise an error
message will appear, the safety contacts will open and the unit will not be
ready for operation until the supply voltage has been switched off and then on
again.
Set operating modes } Switch off supply voltage. } Select operating mode via
the operating mode selector switch “mode”. } If the operating mode selector
switch “mode” is in its start position (vertical position), an
error message will appear.

Operation
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. Open the safety contacts (switch
off output) and start the device again, so that the internal diagnostics can
check that the safety contacts open correctly } for SIL CL 3/PL e at least 1x
per month } for SIL CL 2/PL d at least 1x per year
NOTICE The safety function should be checked after initial commissioning and
each time the plant/machine is changed. The safety functions may only be
checked by qualified personnel.
The unit is ready for operation when the Power LED is permanently lit. LEDs
indicate the status and errors during operation:
LED on LED flashes LED off
INFORMATION Status indicators and error indicators may occur independently. In
the case of an error display, the “Fault” LED will light or flash (exception:
“Supply voltage too low”). An LED that is also flashing indicates the
potential cause of the error. An LED that is lit and is static indicates a
normal operating status. Several status indicators and error indicators may
occur simultaneously.
Status indicators

IN1 Input circuit at S12 is closed.
IN2 Input circuit at S22 is closed.

Supplementary data
CAUTION! 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 frequency and the load of the relay
output. If the service life graphs are not accessible, the stated PFH value
can be used irrespective of the switch frequency and the load, as the PFH
value already considers the relay’s B10d value as well as the failure rates of
the other components.
Service life graph 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. Unit types with UB 24 VDC

000 000 cycles Provided the application to be implemented requires fewer than
2 000 000 cycles, the PFH value (see Technical details [ 22]) 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 DC contactors, use flywheel diodes for
spark suppression.

Example } Inductive load: 0.2 A } Utilisation category: AC15 } Contact service
life: 1 000 000 cycles Provided the application to be implemented requires
fewer than 1 000 000 cycles, the PFH value (see Technical details [ 22]) can
be used in the calculation. To increase the service life, sufficient spark
suppression must be provided on all relay contacts. With capacitive loads, any
power surges that occur must be noted. With DC contactors, use flywheel diodes
for spark suppression.
