Manufacturing workshops and technical service installations in buildings are increasingly subject to more stringentsafety requirements.Good equipment is safe equipment, which combines:- safety: of persons (risk limited to an acceptable level),- reliability of operation: of the production tool (machine always able to perform its function)Safety is achieved by:- simultaneously optimising safety and reliability of operation,- applying fundamental principles: redundancy, self-monitoring,- making reliability a design consideration (failure causing the machine to react in a specified way, positive safety),- ease of maintenance

All dangerous areas must be identified and have restricted access, controlled in a secure manner, i.e. any breakdownor careless operation must result in the automation system failing to a non-dangerous position.It should be noted that the use of safety products alone does not necessarily mean that the machine conforms to themachinery directive.It is in fact correct operation, wiring, association with other devices and scheme used which make the entire machine safe.It is more important to think in terms of safety solutions rather than safety products.

Self-monitoringConsists of automatically checking,at each operating cycle, theoperation of any component whichchanges state.

The next cycle can be inhibitedor enabled.

RedundancyConsists of compensating for thefailure of one component by thecorrect operation of another, basedon the assumption that both will notfail simultaneously

RedundancyConsists of compensating for thefailure of one component by thecorrect operation of another, basedon the assumption that both will notfail simultaneously

Detection of initial fault.Ensure non-dangerous positioning (machine stops in safe state).Ensure the safety of personnel operating industrial machines.

The use of a Preventa safety module with redundancy and self-monitoring functions allows a category 4 control systemto be built in accordance with standard EN 954-1 (parts of control systems relating to safety).

Redundancy function

This function is achieved by providing dual circuits at the design stage, together with a check function which will only permita control action when at least two output signals are identical.

Self-monitoring function

Preventa safety modules incorporate relays with mechanically linked N/O and N/C contacts.This technique ensures that all N/O and N/C contacts within each relay remain synchronised.The self-monitoring function is achieved by checking the correct operation of the linked contact relays which are energisedduring the current operating cycle.The method for detecting the failure of a N/O contact in a mechanically linked contact relay consists of checking the correctoperation of its N/C contacts which are thus incorporated in the self-monitoring circuit. This is only possible if mechanicallylinked relay contacts are used.

Objective

Basic principles

Definitions


Basic principles

If an initial fault is undetected,corrective action is not initiatedand a second fault may occur thuscompromising safety.

An initial fault in the safety circuits is detected before a second fault can occur(next cycle inhibited).

The control signal from the protection device (emergencystop in the circuit on the left) acts directly on the powercontactor of the device.

In this type of scheme, there is still a risk of simple faults:- Em ergency Stop button auxiliary contact being shorted

out,- KM1 contactor sticking in.

When the operator presses an Emergency Stop button,the instruction is not processed, and another sequencecan begin following the emergency stop, despite thepresence of the fault.

(1) A safety function is a function whose non-executionor untimely execution results in immediate placing of theequipment in a non-hazardous condition.

Operation of the control circuit without interposing relays

Operation of the control circuit with interposing relays

Preventa safety modules provide a reliable interposing relay function by overcoming a number of risks associated with:

- control circuit fault (inputs),- power circuit fault (outputs),- safety module internal component fault.

The safety function remains operative whenever any one of these faults occurs.

For the use of mechanically linked contact relays CA2-DN22/DN31 and LC1-D09/D18/D25, LP1-D09/D18/D25, withcontacts which can be used in the feedback loop, please consult your local representative or agent.

Determining the electrical durability according to EN 60947-5-1 (table C2)

Ie: Operational current measured.Ue: Operational voltage measured.Cos ϕ: Power factor.T0,95: Time taken to reach 95 % of rated current.

The tests are carried out with a frequency of 6 switching operations per minute and with no additional protection of thecomponents connected to the safety outputs.The use of additional protection for the components connected to the safety outputs significantly increases the durabilityof the safety outputs.

Determining the breaking capacity according to EN 60947-5-1 (table 4)

e: Operational current measured.Ue: Operational voltage measured.Cos ϕ: Power factor.T0.95: Time taken to reach 95 % of rated current.

Comments :The maximum values for the breaking capacity of the safety outputs in the various utilisation categories are not fixed anddepend on the power factor and on the switching frequency. The test definition for the “breaking capacity” and “durability”tables in European standard EN 60947-5-1 uses different values for the power factor and the switching frequency.

The power factor (cos ϕ) in the “breaking capacity” table (0.3) is greater than that in the “durability” table (0.7)

The switching frequency of the safety outputs is higher in the “breaking capacity” table (60 switching operations per minutefor the first 1000 switching operations) than in the “durability” table (6 switching operations per minute).

Consequently, the maximum breaking capacity values determined using the “breaking capacity” table are lower thanthose in the “durability” table.

XPS-FB XPS-FB

Preventa safety module XPS-FB meets the safety requirements for monitoring the operation of 2 limit switches used onguards for the protection of personnel (e.g. grilles, protective covers, mechanical shielding, etc.). It is also possible tomonitor the operation of two photo-electric detectors with relay output (e.g. access to robotised areas). To do this, eachdetector must be fitted with a N/O contact and a N/C contact or an N/C + N/O changeover contact. The contacts mustnot, however, be of the make before break type.

Module XPS-FB monitors correct operation of the limit switches connected to it when the guard moves. It automaticallydetects any operating or electrical wiring fault in the limit switches. Detection of a fault (shorting, change of contact stateduring operation, etc.) causes immediate opening of the safety contacts in the module and subsequent stopping of themachine’s dangerous movement.

After the module has been energised, the guard must be opened and closed again to check that the limit switches areproperly connected and no faults are present. This function can be simulated by means of the reset button. With thefeedback loop closed, the safety circuits of the module are actuated after closing the guard and (optional) operation ofthe Start button.

The feedback loop allows self-monitoring of any contactor or control relay used to increase the number of outputcontacts and/or to increase the breaking capacity. Any contactor or control relay used for this purpose must incorporatemechanically linked contacts.

The function of the Start button on module XPS-FB is determined by the terminal connections. When terminals Y3-Y5are linked, the Start button is included in the monitoring circuit and the safety outputs are activated on the falling edgeof the output signal when the Start button is released. When terminals Y3-Y4 are linked, the safety outputs are activatedimmediately after the Start button is pressed. This configuration allows the safety modules to function automatically assoon as the safety guard is closed, provided that the Start button is shorted.

Locking or interlocking device based on the principle of redundancy and self-monitoring.The safety modules perform both functions.

Machines with instant stopping. Locking (stopping time < access time) (1)

High inertia machines with long stopping times. Interlocking (stopping time >access time) (1)

(1) Stopping time: Time elapsed between actuation of the machine stop control and the moment the machine stops(risk eliminated).Access time: Time required for a person to access the hazardous zone (calculated on the basis of an approach speed).

Two-hand control stations are designed to provide protection against hand injury. They require machine operators tokeep their hands clear of the dangerous motion area. The use of two-hand control is an individual protective measure,which can safely protect only one operator. Separate two-hand control stations must be provided for each operator ina multiple-worker environment. Preventa XPS-BA and XPS-BC safety modules for two-hand control comply with the -requirements of European standard EN 574 for two-hand control systems.The control stations must be designed and installed such that they cannot be activated involuntarily or easily renderedinoperative. Depending on the application, the requirements of type C standards specific to the machinery involvedmust be met (additional personal protection methods may have to be considered).To initiate a dangerous movement, both operators (two-hand control pushbuttons) must be activated within an interval≤ 0.5 s (synchronous activation). If one of the two pushbuttons is released during a dangerous operation, the controlsequence is cancelled. Resumption of the dangerous operation is possible only if both pushbuttons are returned to theirinitial position and reactivated within the required time interval.The safety distance between the control units and the hazardous area must be sufficient to ensure that when only oneoperator is released, the hazardous area cannot be reached before the dangerous movement has been completed orstopped.

Components for safety applicationsPreventa safety modulesfor zero speed detection

XPS-VN zero speed detection modules are used to detect the stop condition of electric motors. Their most commonapplications include:- providing the unlock signal for electrically interlocked sliding or removable machine guards,controlling rotation direction signals for reversing motors and engaging locking brakes after a motor has come to astandstill.

As electric motors run down, a remanent voltage is produced in the windings of the motor due to residual magnetism.This voltage is proportional to the speed of the motor and, therefore, decreases as the motor comes to a standstill.This remanent voltage is measured in a redundant manner so as to detect the stop condition of the motor. The cablingbetween the motor windings and the inputs of the XPS-VN module is also monitored to prevent a cabling breakage orfault being seen as a stopped motor.A transformer should not be used to connect the motor to terminals Z1, Z2 and Z3 since there is no monitoring of theconnection with the motor winding via the resistor monitoring.

XPS-VN safety modules are suitable for detecting the stop condition of all types of a.c. or d.c. motor driven machineswhich, when the motor runs down, produce a remanent voltage in the windings due to residual magnetism. Thesemachines can be controlled by electronic devices, such as variable speed drives or d.c. injection brakes.The input filters for standard XPS-VN modules are designed for a frequency of up to 50 Hz.For motors operating at a frequency higher than 50 Hz, which therefore produce a high-frequency remanent voltage,special modules XPS-VN////HS should be used.

XPS-VN safety modules have two potentiometers mounted on the front face of the module which allow independentadjustment of the switching threshold for each input circuit. This allows adjustment for different types of motors andapplication requirements.

To assist diagnostics, XPS-VN modules incorporate 4 LED indicators and 2 solid state outputs to provide informationon the status of the zero speed detection circuit.

Components for safety applicationsPreventa safety modulesfor lift control

When the car is parked at a landing, with the doors open, some lifts automatically correct their level (isolevelling) in relationto the landing in order to compensate for any differences generated by modification of the load in the car. During this operation, European standard EN-81 recommends that the presence of the car be checked within an area of±0.2 mm around the landing (door unlocking zone), by means of a safety circuit which will cause the car to stop if it movesout of the specified zone.The use of an XPS-DA safety module which checks the presence of the car in the specified zone at two points meets thisrequirement.The module is fitted with two safety outputs and two solid state outputs for signalling functions. Four LEDs on the frontface of the module provide visual indication of the state of the safety circuit.The position of the car in relation to the landing is detected by two limit switches in the lift shaft. It is also possible to usenon-contact sensors (magnetic sensors with reed contact).When the car reaches the preset position and when it is within the permissible tolerances in relation to the landing, thetwo safety circuits in safety module XPS-DA close and allow isolevelling of the car with the doors open. Any change inone of the input signals (car outside the specified zone) or detection of a fault (break in the wiring, short-circuit...) causesimmediate opening of the safety outputs in module XPS-DA and therefore stopping of the car.

Safety module GNK-L is used for automatic monitoring of overtravel on all types of linear presses : hydraulic, pneumaticand mechanical. It has been developed for monitoring the overtravel, before the start of production, on presses fittedwith either a two-hand control unit or security light barrier.

This module must be connected to 2 limit switches :- limit switch S2, which detects top dead centre,- limit switch S3, which detects the presence of normal overtravel during the test cycle performed after switch-on (beforeproduction starts). To allow the slide to reach a high speed, limit switch S3 must be located approximately in the middleof the tools full stroke.

The permissible overtravel corresponds to the length S of the linear cam, which operates limit switch S3. Length S isnormally determined by the linear press manufacturer, based on the least favourable conditions (maximum tool weight,operating rate and stroke, high oil temperature, etc.).

Safety module GNK-L operates only during the first press cycle after switch-on : the test cycle.

The length of cam S determines the maximum permissible overtravel distance.

Overtravel does not exceed length S. In this case, the tool stops at the position described under 3 as long as theinstruction provided by the control station is valid. A new instruction must be given to enable subsequent cycles.Safety module GNK-L will repeat the correct overtravel test when the machine is next switched-on.

During the test cycle, overtravel exceeds length S. In this case, the tool is in the position described under 3.Limit switch S3 is deactivated and the tool moves down, then stays at bottom dead centre, the position described under 4.The slide cannot move back up, even if a new instruction is given from the control station. It can be returned to top deadcentre only by pressing the manual “UP” button. The next cycle is inhibited. Maintenance will be required before a furthertest cycle is initiated. Production cannot resume until a further test cycle is performed successfully (normal overtravel).

First case : Normal overtravel

1 Machine idle 2 Start of cycle : 3 Braking as soon as the cam reaches S3tool downstroke

Second case : Abnormal overtravel due to wear, hydraulic leak, unsuitable load, etc.

The XPS-PVT safety module is a dedicated module for monitoring hydraulic safety system valves, which control themovements of dangerous machinery. The operating principle of this module is explained in the circuit diagram of a hydraulic safety system for linear presses(see below).

This hydraulic safety system features a 3-position piston which controls the up and down stroke of the operating cylinder.The circuit is equipped with a safety valve, to complete the redundant system. This circuit must be activated to enable theup and down stroke of the cylinder. If either of the two pistons becomes defective (for example, due to a broken spring or to oil contamination), and the valvepiston shifts from its normal position toward the open position, the XPS-PVT module will detect it and preventresumption of the piston stroke.Proximity sensors integrated into the valve to detect the valve positions and connected to the XPS-PVT module mustbe damped when the valve coils are in the de-energised state (position zero).The sensor circuits of the XPS-PVT module are designed to allow connection of NPN and PNP proximity sensors orsensing components. Either 2-wire or 3-wire types can be used.The diagram on page 38740/4 shows how to connect proximity sensors.

Components for safety applicationsPreventa safety modulesfor dynamic monitoring of double-bodied solenoid valves

Safety module XPS-PVK is specially designed for dynamic monitoring of the safety valves in eccentric presses,conforming to European standard EN 692.This standard establishes the specifications related to safety control systems for presses equipped with friction clutches.To meet the requirements of this standard, the clutch/brake control must be monitored dynamically.

This function is provided by a double-bodied solenoid valve (safety valve for presses) which performs the functions oftwo valves mounted in one body.The position of the two valve pistons can be monitored by proximity sensors, mechanical limit switches or pressureswitches.

Module XPS-PVK checks for the correct operation of the double-bodied safety valves at 3 points in the cycle.

To set up an automatic disconnect of the XPS-PVK module at the first machine stroke, a N/C auxiliary contact mountedon the main control contactor or on another contactor/relay, activated at the same time, can be wired to terminals 7 and8 in parallel with the RESET button.

Operating principle

/ Start at top dead centre: checks the rest position of the two valves./ Take-on point (transfer function): checks that the two valves are in the “activated” (energised) position./ Press stop trigger point: checks that the two valves return to the rest position. Return must be simultaneous for bothvalves within a defined time period.

If a fault is detected during the cycle, the XPS-PVK module will stop the slide stroke and will also inhibit the start of another cycle.

Permissible overtravel zone

Safe

zone(usuallyslideupstroke)

Safety module XPS-OT is used on eccentric presses to monitor overtravel and ensure that the press slide stops ina non-dangerous position, that is, top dead centre (TDC) during normal (non-emergency) operation. Use of thismodule, designed in accordance with standard EN 692 relating to mechanical press safety, makes it possible to createa redundant, self-monitoring control system.

The two essential functions of this safety module are :

Control of the dangerous part of the cycle (generally the slide downstroke) is usually achieved from a two-hand controlstation associated with safety module (type XPS-BC) monitoring this station to qualify as a Category 4 control systemaccording to standard EN 954-1.Overtravel monitoring is performed on each cycle by safety module XPS-OT.

Cam 1 is associated with the OTS limit switch (LS), cam 2 with the UN limit switch (the limit switches must be locatedon different cams for safety reasons).The OTS limit switch is deactivated at TDC, at which point the UN limit switch is activated. Point A1 of cam 1 is located approximately 300° from TDC and, when reached, the press comes to a standstill: A1 isthe press stop trigger point.Point B1, located approximately 10° after TDC, constitutes the end of cam 1: If B1 is exceeded during stopping, theovertravel is abnormally long, the press locks up and the next cycle is inhibited.Point A2 of cam 2 functions like point A1 on cam 1 (contact state of the UN limit switch reversed in relation to thecontact state of the OTS limit switch).Point C2, located approximately 150° after TDC, corresponds to the 8 mm tool closing dimension. Stop instructionsissued after C2 is reached are not executed until point A2 is reached.

Operating principle

/ Trigger the end of cycle stop sequences slightly before top dead centre (at point A) so as to reach a standstillstop at TDC. After TDC, the permissible overtravel is approximately 10°. The safety module immediately detects anyovertravel. Overtravel is indicative of braking device deterioration. In this case, jog mode must be used to move the slideback to TDC. The next cycle will be inhibited to allow maintenance to be performed on the braking device (cam 1).

/ Take over control monitoring during the dangerous part of the cycle (slide downstroke). Any stop instruction issuedbetween TDC (0°) and point C (approximately 150° after TDC) causes an immediate stop of the press. Thisapproximate value of 150° corresponds to the 8 mm tool closure dimension (safety point). When a stopinstruction is issued after this point, the press completes the cycle and comes to a complete stop at TDC (cam 2).

Components for safety applicationsPreventa safety modulesfor amplifier relay applications

The XPS-NS module is designed for reliable detection and amplification of signals generated by :- c 24 V proximity sensors (2-wire, 3-wire NPN or 3-wire PNP types),- magnetic sensors,- limit switches.The amplifier generates output signals which can be used in mechanically linked contact relays in safety circuits.Applications include : solenoid valve proximity sensors for eccentric press clutch/brake functions, magnetic sensors orlimit switches mounted on protective guards, etc.

By applying a nominal voltage to terminals A1/A2, two separate c 24 V supplies are generated, terminals A+ = (+) /A– = (–) and terminals B+ = (+) / B– = (–), the latter being interconnected such that an internal short-circuit is generatedif the proximity sensors are improperly connected. In turn, the short-circuits, are displayed by the corresponding LED“POWER SUPPLY 1” or “POWER SUPPLY 2”.

Two other LEDs indicate the status of their corresponding proximity sensor.Each output relay (linked contacts) contains a N/O volt-free contact and a N/C volt-free contact. A monitoring circuitconnected to terminals 51-52 comprises 2 N/C contacts in series for each of the two output relays. Possible sensor orlimit switch connections and their combinations are shown in the electrical connections diagram on page 38772/3.

Caution : If S1 and S2 are 2 proximity sensors placed close to each other, 2 different types of sensor should be usedto avoid interference.For example : S1 : 2-wire,S2 : 3-wire NPN.

(1) Automatic start: there is no start contact or it is shunted.Unmonitored start: the output is activated on closing of the start contact.Monitored start: the start input is monitored so that there is no start-up in the event of the start contact being shunted or the start circuit being closed for morethan 10 seconds.Start-up is triggered following activation of the start button (push-release function) on opening of the contact.(2) Tool zone guard with 3rd limit switch. Additional rear guard (optional) with automatic start. The opening of the guard cuts all outputs.

Operating principle

Preventa safety modules - monitorsXPS-MP are designed to conformwith category 4 of the standard EN954-1.They enable two independent safetyfunctions (selected from a choice of15 pre-defined configurations) to beperformed using the same product.Configuration selection is easilymade using 3 buttons on the frontface of the module.

The 15 preprogrammed safety functions provide a solution for the majority of safety applications up to level 4conforming to the standard EN 954-1, for example: monitoring emergency stop, limit switches, safety mats and edges,agreement control with handle, monitoring type 4 security light barriers conforming to EN 61946-1 which have relayoutputs (for example, XUS-LA type barriers, see page 30302/3) and monitoring contactless magnetic switches.XPS-MP monitors incorporate 6 safety outputs (3 per function) and 3 solid state signalling outputs for signalling to theprocess PLC.

To aid diagnostics, the modules have LEDs on the front face which provide information on the monitoring circuit status.They also indicate and assist selection of the 2 required configurations.
