shut down and protected against being restarted.

Leuze electronic MC3x 7

2.1.1 Proper use

• Safety Relay, sensor and actuator are intended for use in protective door monitoring in accordance with EN 1088 and EN 60947-5-3.

• They are used for the safety-related monitoring of moveable guards and, thus, for the protection of persons at entry or access areas of points of operation on machines and systems (e.g., protective door, sliding gate, protective hoods).

• Safety Relay, sensor and actuator must only be used after they have been selected in accordance with the respectively applicable instructions and relevant rules, standards and regulations regarding labor protection and safety at work, and after they have been mounted on the machine, connected, commissioned, and checked by a competent person.

• When selecting the Safety Relay, sensor and actuator, it must be ensured that their safety-related capability meets or exceeds the required Performance Level ascertained in the risk assessment. For the table of safety-related characteristic parameters, see chapter 13 „Technical data“.

• The MC3x sensors may only be operated with the approved MC3x actuators and MSI-MC3x Safety Relays. Proper function with respect to safety can be ensured only if compatible components are used.

• Safety Relay, sensor and actuator must be in perfect condition and periodically inspected by competent persons.

• If the point of operation can be reached within the stopping time of the dangerous process, a Safety Locking Device must be used instead of the Magnetically Coded Sensor.

• The guard must be dimensioned and mounted in such a way that reaching or stepping around is not possible.

• MC3x only reports persons upon opening of the guard, not whether persons are located in the danger zone. For this reason, a start/restart interlock in the safety chain is essential for access safeguarding.

• Sensor and actuator must be connected to the fixed or moveable guard in a permanent and tamperproof manner. The mounting conditions must be observed (see chapter 6 „Mounting“).

• The sensors and their actuators are to be protected against strong physical shocks and vibrations. Observe the permissible environmental conditions for storage and operation (see chapter 13 „Technical data“).

• Sensor and actuator must be protected against foreign bodies (e.g., iron filings and blasting agents).

• The normally closed contacts of the MSI-MC310 are used to signal the state. Use as safety-related contacts is not permitted.

• Sensor and actuator must be connected in such a way that a dangerous process can only be activated while the guard is closed and so that a stop command that ends the dangerous process is triggered upon opening of the guard.

• Cable gland, insulation materials and connecting wires of the appropriate protection rating are to be used.

• Safety Relay, sensor and actuator must be replaced after a maximum of 20 years (see chapter 13 „Technical data“). Repairs or the exchange of parts subject to wear and tear do not extend the ser vice life.

• Damaged components must be replaced immediately.

• Sensor or actuator must neither be tampered with nor may their correct position be changed.

• External magnets must not be used nor may the contacts be bridged.

• No structural changes may be made to Safety Relay, sensor or actuator. When manipulating, the protective function is no longer guaranteed. In addition, all guarantee claims against the manufacturer shall no longer apply.

Safety

2.1.2 Foreseeable misuse Any use other than that defined under the “approved purpose” or which goes beyond that use of the Safety

Relay, sensor and actuator is considered improper use!

Leuze electronic MC3x 8

Safety Relay, sensor and actuator must not be used under the following conditions, .e.g.:

• The safety of multiple persons is dependent on the function of Safety Relay, sensor and actuator (e.g. nuclear power plants, trains, aircraft, motor vehicles, incinerators, medical devices)

• Where subjected to strong physical shocks or in potentially explosive or easily flammable atmospheres

• Danger posed by ejected objects or the spraying of hot or hazardous liquids from within the danger zone

• Presence detection of persons in danger zones

• Looping into the safety circuit parts that are not relevant to safety

• The combination of non-approved parts with Safety Relay, sensor or actuator

• Combination with non-compatible controls (current limiting, logic)

• Mounting positions that enable reaching or stepping around

• Using the sensor or actuator as limit stop

• Insufficiently stable mounting locations or unsecured mounting of sensor or actuator

• Mounting on ferromagnetic materials.

2.2 Competent persons

3 Device description

The sensor system consists of the MC3x sensor, the MC3xA actuator and the corresponding MSI-MC3x Safety Relay.

The sensor contains a special combination of reed contacts that are contactlessly activated by the coded magnetic field of the actuator. For guards that are accessible from behind, a reset button (RES) can be connected to the MSI-MC3x for manual starting. Evaluation of the RES signal is monitored edge-depen- dent.

If, for example, a door is opened, the actuator mounted here is separated from the sensor, which is located on the stationary part of the guard. If the change in the position of the actuator reaches the maximum value of the defined distance, the switching state is detected by the Safety Relay connected to the sensor and is signaled to the control via two fail-safe OSSD contacts.

As a result, risky machine movements can only be executed while the guard is closed or if a stop command is executed while the guard is being opened.

Moreover, additional switching elements can be integrated in the safety circuit. The monitoring of relays or contactors is possible via their feedback contacts K3, K4 in the start circuit of the MSI-MC3x.

Due to the closed design of the sensors, they can also be used in critical environmental conditions (e.g., in areas where there is exposure to dust).

The system offers a high degree of safety and satisfies the following standards:

• Performance Level (PL) e (EN ISO 13849-1: 2008)

• Safety category 4 (EN ISO 13849-1:2008)

Depending on the application, various MC3x series are available.

4.1 Start/restart interlock

(Connection of the reset button between pin OUT / 24 V and pin SR of the MSI-MC310) (Connection of the reset button between pin A2 and pin SR1 / SR2 of the MSI-MC311) The start/restart interlock prevents automatic release of the safety circuits and automatic start-up of the

system (e.g., if the protective door closes again or an interruption of the voltage supply is restored). The system may not be manually released with the reset button until no persons are located in the danger

zone (see chapter 7.7 „Unlocking start/restart interlock“).

4.2 Automatic start/restart

(Bridge between pin OUT / 24 V and pin A of the MSI-MC310) (Bridge between pin SR1 / SR2 and pin EDM of the MSI-MC311) The automatic start/restart interlock enables immediate release of the safety circuits and automatic start-

up of the system (e.g., if the protective door closes again or an interruption of the voltage supply is restored).

This operating mode is only permitted if it is not possible to reach or step behind the guard (see chapter 7.7 „Unlocking start/restart interlock“).

4.3 Contactor monitoring (EDM)

(Connection in the start circuit between pin OUT and pin SR of the MSI-MC310) (Connection in the start circuit between pin S12 and PIN EDM of the MSI-MC311) The MSI-MC310 / MSI-MC311 monitors the feedback circuits of the connected relays or contactors.

The two OSSDs are not activated until:

• all actuators of the connected sensors are in the specified distance range

• all connected sensors are activated

• opening of the contacts (reset button, EDM contacts) causes the signal at pin SR to drop out

5 Applications

The MC3x series is used in position monitoring of moveable guards, e.g. (sliding) gates, flaps or hoods.

WARNING

Unexpected machine start-up may cause severe injuries. If the guard is accessible from behind, e.g., in the case of access guarding of danger zones, only the

opening of the door is detected; persons present within the danger zone are not detected after the door is closed.

 Only operate access guarding in the start/restart interlock operating mode or take additional safety

measures.

6 Mounting

WARNING

Improper mounting may result in serious injury! The protective function of the sensors is only ensured if used in the intended area of application and if

they are mounted professionally.

 Mounting may only be performed by competent persons.  Observe the relevant standards, regulations and these instructions.  Do not use the sensor in areas under the influence of strong magnetic fields.  After mounting, check the sensors for proper function

6.1 Selecting the position and arrangement of sensor and actuator

WARNING

Improper mounting may result in serious injury! The protective function of the sensors is only ensured if, after the guard is opened, the dangerous

process can be safely stopped before it is reached by a person.

 Mount the sensors with an adequate safety distance to the danger zone.  Take all delay times into account (e.g., the response times of the control elements, the stopping time

of the machine)

Mounting

 Select the mounting locations so that the following conditions are satisfied acc. to EN 1088:

• For doors/flaps that swing open, the position of sensor and actuator is opposite the hinge side.

• The position of sensor and actuator allows the cut-out distance Sar to be reached upon opening of the moveable guard.

• The position of sensor and actuator makes it impossible to reach or step behind the moveable guard.

• Make certain that the gap dimension between the fixed and moveable part of the guard is not wide enough for reaching or stepping behind.

• The position of sensor and actuator makes it impossible for a person to reach the dangerous area during the stopping time of the machine after the guard is opened.

• The position protects the sensor from physical shocks and vibrations that exceed specifications (see chapter 13 „Technical data“).

• Adjacent Magnetically Coded Sensors must be separated by at least 50 mm.

• The position of sensor and actuator must not lie within the range of influence of blasting agents or magnetic particles.

• Mounting on ferromagnetic materials (e.g., iron, nickel, cobalt) is to be avoided.

• When mounting on stainless steel surfaces, spacers are to be used and the safety-related switching distances are to be inspected.

• The position of sensor and actuator must facilitate form-fitting mounting.

• Accessible to qualified personnel for testing and replacement

• Cannot be manipulated by operators though removal, turning, short-circuiting (e.g., by means of covered mounting)

NOTICE Faulty or incorrect alignment will result in an operating fault.  The alignment of sensor and actuator within the scope of start-up is to be performed only by trained

personnel.

 Observe the data sheets and mounting instructions of the individual components.

6.2 Mounting and aligning sensor and actuator

NOTICE Observe the switching distances and ensure that the markings on sensor and actuator line up while the

guard is closed.

Figure 6.6: MC388x Figure 6.7: MC336x Figure 6.8: MC330x

Proceed as follows:  Select the position of the sensor on the fixed part of the guard (see chapter 6.1 „Selecting the position

and arrangement of sensor and actuator“).

 Select the position of the actuator on the moveable part of the guard (see chapter 6.1 „Selecting the

position and arrangement of sensor and actuator“).

 Drill the bore holes acc. to the specified dimensions (see chapter 14 „Dimensions and weights“).  For round actuators, take into account the anti-twist protection by providing an appropriate recess.  Loosely screw the sensor and actuator at the defined positions. Use the washers.  Align sensor and actuator with one another so that when the guard is closed, the markings (e.g., arrows,

notches, lines) are aligned, i.e., are opposite one another. A lateral offset reduces the switching distance.

Leuze electronic MC3x 22

Mounting

 Align sensor and actuator with one another so that while the guard is closed, they do not touch one

another (minimum distance: 1 mm).

 Do not consider sensor and actuator to be limit stops.  Make certain that the cut-in and cut-out points (Sao, OFF, Sar see table 6.1) can be reached without

mechanical tension in the moveable guard.

 Secure sensor and actuator within the specified distance values "Sao" and "OFF".  After aligning, permanently fasten sensor and actuator with locking screws (to 10 Nm).

Proceed as follows:  Align the actuator so that the distance between sensor and actuator is within the specifications (Sao and

OFF) while the guard is closed.

 The fitting position of sensor and actuator can be freely selected.  If necessary, provide a constraining guide for the moveable part of the guard. The edges of the move-

able and fixed part of the guard must be aligned (e.g., door and frame).

 Do not use the sensor as a limit stop, but rather provide a separate mechanical limit stop.  Install a locking or snap mechanism for the moveable part of the guard to prevent it from swinging open.  If it is expected that the moveable part of the guard will warp, the mounting position of sensor and actu-

ator can be adjusted to offset this somewhat if necessary. Check the resulting gap dimensions to determine, e.g., whether it allows a person to reach behind.

 Fasten sensor and actuator with rivets or tamperproof screws on a form-fitting surface so that they can-

not be detached.

 If necessary, mount sensor and actuator so they are covered.  Note the minimum approach speed (see chapter 13 „Technical data“).

7.4 Connecting to the machine control

The safety-related parts of the control include, in addition to the Safety Relay, sensor and actuator described above, the subsequent control elements up to the power-transfer elements that are to be stopped safely and timely. Special attention must be given here to the adherence to the required safety category. Important information on this topic can be found in harmonized European standard EN ISO 13849-1.

Essential prerequisite for the safe operation is the possibility of electrically influencing the interruption of the dangerous movement as well as a sufficiently short machine stand-still time. These must be incorpo- rated in the calculation of the safety distance as must the response times of the safety-related chain (Safety Relay, sensors, contactors, etc.).

Setting the device into service

WARNING

Improper use of the Safety Relay may result in serious injury!  Make certain that the entire device and the integration of the protective device was inspected by com-

petent and instructed persons.

 Make certain that a dangerous process can only be started while the guard is closed.

Prerequisites for start-up:

• Safety Relay, sensor and actuator are mounted according to these instructions and connected according to the wiring plan

• operating personnel have been trained in the correct use

• The dangerous process is switched off, outputs of the MSI-MC3x are disconnected and the system is protected against being restarted

 During start-up, test the function of the sensors and the Safety Relay (see chapter 8 „Testing“).  Prior to the initial start-up on a power-driven machine, make certain that a competent person inspects

the connection of the connected guard at the Safety Relay as well as the integration of the complete system in the machine control.

 Before switching on the supply voltage for the first time, make certain that the outputs of the Safety

Relay have no effect on the machine.

 Make certain that the switching elements that put the machine which poses a danger into motion are

safely switched off or disconnected and are protected against being restarted.

Electrical connection

The same safety measures apply after each function change, after repairs or during maintenance work.

7.5 Switching on

Requirements for the supply voltage (power supply unit):

• Safe mains separation is ensured (acc. to IEC 60742).
