6.1 Actuating directions

The sensor recognises the actuator from three different directions 2�

► When mounting the device, align the central marks

in parallel to each other�

Reference marks (central mark) Actuating direction

of the sensor and the actuator

• The actuator must not touch the sensor during operation�

• Do not adjust the device using mechanical force�

• Only mount on a flat surface to avoid damage or changes of the sensing range� When using several sensors, a minimum distance of 50 mm in each direc-

tion must be maintained�

► Fasten the sensor and the actuator with two screws each (M4, > 18 mm) (tight-

ening torque 0�8��2 Nm)�

Using less than two screws for each component is not permissible� According to EN ISO 14119, the actuator must be fixed immovably�

Safety screws with one-way heads, rivets or the like are to be used� After mounting, insert the supplied cover caps to make it more difficult to access

screws or rivets�

Safety-related logic unit Programmable Logic Controller (PLC) Programming input (MN702S, MN705S)

In case of a single fault, the supply voltage must not exceed a maximum of 60 V DC� (This requires the safe separation between power supply and transformer SELV / PELV�)

The maximum permitted cable length is 50 m�

8 Programming

The programmable version of the sensor is provided with a special programming input (IN3) that recognises the stored code in a new actuator�

The programming can be repeated as often as you like� After successful programming, the sensor will only recognise the code of the most recently programmed actuator�

The sensor may only be programmed by qualified staff�

9 Operation

9.1 Switching state of the outputs

9.1.1 The safe state

The safe state is when the output is switched off (zero-current state: Logic "0") of at least one of the outputs OS1 or OS2 (OSSDs)� If one of the outputs OS1 or OS2 is switched off, the subsequent safety-related logic unit must bring the complete system into the state defined as safe�

9.1.2 The switched state

If the coded actuator is in the enable zone and if there is no sensor error, both outputs OS1 and OS2 (OSSDs) are enabled (logic "1")�

9.1.3 Cross fault / short circuit

• A cross fault between both outputs (OS1 and OS2) is detected by the fail-safe

UK

sensor and results in the outputs (OSSD) being switched off� The outputs OS1 and OS2 remain switched off until the error has been removed or a voltage reset has been carried out�

• A cross fault (short circuit) between one of the two outputs (OS1 or OS2) and

the supply voltage results in the other output (OS2 or OS1) being switched off�

9.2 Interface classification

The interface complies with interface type C class 2 according to the ZVEI position paper CB24I Ed� 2�0�
