2. General safet regulaons and protecve measures
• The manufacturer and users of the plant / machine on which the protecon is being used are responsible
for implemenng and following all applicable safety regulaons and rules.
• When used in conjuncon with the higher-order controller, the protecon guarantees funconal safety,
but not the safety of the enre plant / machine. The safety of the enre plant / machine must, therefore,
be assessed in accordance with machinery direcve 2006/42/EC or appropriate product norm before
using the device.
• The operang instrucons must always be available at the place of installaon of the protecon.
They must be read thoroughly and observed by all persons involved in the operaon, maintenance and
servicing of the protecon.
• The protecon must only be installed and commissioned by professionals familiar with these operang
instrucons and the applicable operaonal safety and accident prevenon regulaons. All of the instruc-
ons provided in these operang instrucons must be observed and followed.
All electrical work must only be performed by skilled electricians.
• All relevant electrical engineering and Employer's Liability Insurance Associaon safety regulaons must
be observed.
• During work on the switching unit, it is to be switched to zero potenal, checked to ensure that it is at
zero potenal and protected against being restarted.
• If the potenal-free contacts of the relay outputs are supplied externally with a dangerous voltage, make
certain that these outputs are also switched o during work on the switching unit.
• The switching unit does not contain any components that require servicing by the user. Unauthorised
conversions and repairs made to the switching unit will void all guarantees and the manufacturer’s liabi-
lity.
• The protecon system is to be professionally inspected at appropriate intervals and be documented in
such a way that it is comprehensible at all mes.
Safet advice
• The switching unit enables operaon at 230 V or at 24 V. Connecng the operang voltage to the wrong
terminals destroys the switching unit.
• Do not install in the immediate vicinity of strong sources of heat.
• For capacive and inducve loads, ensure adequate protecve circuits.
The manufacturer assumes no liabilit in the event of non-observance or intenonal
abuse.

3. General
The SK 32 switching unit, designed with two channels, is used for evaluang safety contact mats and for
safeguarding locaons where there is a risk of crushing and cung through the use of safety contact edges
and safety bumpers.
The switching unit complies with EN ISO 13849-1:2008, Cat. 3. To meet Cat. 3 requirements, the switching
unit has a redundant structure with two, two-way polling, forcibly actuated safety relays per channel. A
terminang resistor is integrated in the sensor in order to enable monitoring of the standby current. If the
specied standby current is owing, the output relays are acvated and the switching contacts are closed.
If the sensor is actuated or the sensor circuit is interrupted, the corresponding relay switching contacts open.
The switching states of the relays and the applied operang voltage are indicated by LEDs.
4. Proper use
Proper use of the switching unit is the use as protecon in combinaon with safety contact mats, safety
bumpers or safety contact edges.
Any uses above and beyond these uses constute improper use. The manufacturer assumes no liability
for damages arising from improper use. The device may only be used in special applicaons with the
manufacturer’s express consent.

5.4 Connecng mulple sensors per sensor circuit
ASO sensors must not be connected in parallel.
One or more sensors can be connected to sensor inputs Staonary Opening or Staonary Closing.
For this
purpose, the individual sensors are connected in series according to gure 1. An unused input can be bridged
with an 8.2 k� resistor. k� resistor.k� resistor.
Safet edges SKL:
Up to ve SKL may be connected in series. The maximum total length o the SKL shall not exceed 100 m.
The length of one SKL may be up to 25 m.
The total cable length o the in series connected SKL must not exceed 25 m.
Safet bumper ASB:
Up to ve ASB may be connected in series. The maximum total length o the ASB shall not exceed 15 m.
The length of one ASB may be up to 3 m.
The total cable length o the in series connected ASB must not exceed 25 m.
Safet contact mat ASK:
Up to ten ASK may be connected in series. The maximum total area shall not exceed 10 m
2
.
The maximum size of an ASK is 1350 x 2350 mm.
The total cable length o the in series connected ASK must not exceed 25 m.
Before connecng the sensors that are connected in series, it is recommended that the resistance value of
the arrangement is to be measured. The resistance must be 8.2 k� ± 500 � when the sensor is inacve and
must not exceed 500 � when it is acve.
6. Commissioning
6.1 Prerequisites
• When supplying via terminals 24 V AC/DC, the voltage must comply with the requirements for protecve
extra low voltage (PELV).
• Cables installed outdoors or outside of the switching cabinet must be protected appropriately.
• The limit values for the supply voltage and the switching capacity of the relay specied in the "technical
specicaons" are to be observed.
6.2 Electrical connecon
• Connect supply voltage 24 V DC or AC to terminals 24 V AC/DC or 230 V AC supply voltage to terminals
230 V 50/60 Hz
• Connect sensor to terminals Staonary Opening and Staonary Closing; connect 8.2 k� resistor to any
unused inputs.
• Connect the control circuits to be monitored to terminals Stop Opening and Stop Closing.

6.3 Example of use
7. Troubleshoong
An error can be localised in the system with the aid of the LEDs. Only the green Power LED may illuminate
if the supply voltage has been correctly connected. If the red Staonary Opening LED or the red Staonary
Closing LED illuminates, the connecons of the sensor(s) should be checked (for serial connecon of mulple
sensors). If the error is not at the connecons, the funcon of the electronics can be tested by connecng
an 8.2 k� resistor to the respecve sensor input on the switching unit. If the electronics work perfectly aer
performing the test, the sensors must be checked using an ohmmeter. To do this, the connecon of the
sensor to the safety relay must be disconnected and connected to an ohmmeter. The resistance must be
8.2 k� ±500 � when the sensor is inacve and must not exceed 500 � when the sensor is acve.
Circuit diagram in zero-potenal state. Sensor not actuated
Aer the operang voltage is switched on, the exnguished red LEDs indicate error-free operaon. If one of
the sensors is now actuated, the LED that corresponds to this channel illuminates and the respecve relays
switch. The relays interrupt the control circuit as long as the sensor is actuated.
