�
Correct UseThe safety system MGB is an electromagnetic interlock device with guard lock-ing.
The system comprises at least one locking module MGB-L1-AR-.../MGB-L�-AR-... and one handle module MGB-H...
The locking module MGB-L1-AR-.../MGB-L�-AR-... can be integrated into a switch chain for the safety system CES-AR or operated as a separate system.
In combination with a separating safety guard and the machine control, this safety component prevents the safety guard from being opened while a dangerous machine movement is being performed.
For the control system, this means that
starting commands which cause hazardous situations must become active only when the safety guard is in protective position and the guard locking is in locked position. The locked position of the guard locking must be released only when the haz-ardous situation is no longer present.
Before safety components are used, a risk assessment must be performed on the machine in accordance with
EN ISO 1�849-1, Safety of machinery. Safety related parts of control systems. General principles for design, Annex B
EN ISO 141�1, Safety of machinery. Risk assessment. Principles.
Correct use includes compliance with the relevant requirements for installation and operation, in particular
EN ISO 1�489-1, Safety of machinery. Safety related parts of control systems. General principles for design
EN 1088, Safety of machinery. Interlocking devices associated with guards. Principles for design and selection
EN 60�04-1, Safety of machinery. Electrical equipment of machines. General requirements.
The safety system MGB can only be combined with the intended modules in the MGB system family.
On the modification of system components, EUCHNER provides no warranty for safe function.
Connection of several devices in a CES-AR switch chain is permitted only using devices intended for series connection with the CES-AR. Please check this in the operating instructions of the respective device. For detailed information on opera-tion in a CES-AR switch chain, please see the related CES-AR system manual.
Important!
The user is responsible for safe integration of the device in a safe overall system. For this purpose the overall system must be validated, e.g. in accor-dance with EN ISO 1�849-�.The permissible operating parameters must be observed for correct use (see Technical data).If a product data sheet is included with the product, the information on the data sheet applies in case of discrepancies with the operating instructions.

Important!
In the estimation of the PL for the overall system, a maximum value of 100 years can be assumed for the MTTFd according to the limit value in EN ISO 1�849-1:�008, Section 4.5.�. This corresponds to a minimum value for the PFHd of �.47 x 10-8/h.When up to 10 devices are connected in series, these limit values can be assumed for the entire switch chain as a subsystem. As a subsystem, this switch chain achieves PL e.
Exclusion of Liability and WarrantyIn case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed, or if any servicing is not performed as required, liability will be excluded and the warranty void.
General Safety InstructionsSafety switches fulfill personal protection functions. Incorrect installation or tamper-ing can lead to fatal injuries to personnel.
Check the safe function of the safety guard particularly
after any setup work
after the replacement of an MGB component
after an extended period without use
after every fault
Independent of these checks, the safe function of the safety guard should be checked at suitable intervals as part of the maintenance schedule.
Warning!
Loss of safety function in the event of incorrect connection or incorrect use. Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective.On this topic pay attention in particular to the measures for reducing the pos-sibility of bypassing from EN 1088:1995+A�:�008, section 5.7.The switching operation is only allowed to be triggered by the intended han-dle module MGB-H... that is positively fastened to the safety guard.
The device is only allowed to be installed and placed in operation by authorized personnel who are familiar with the correct handling of safety components who are familiar with the applicable EMC regulationswho are familiar with the applicable regulations on health and safety who have read and understood the operating instructions and the system manual

Important!
Prior to use read the operating instructions and the system manual, and keep these in a safe place. Ensure the operating instructions and the system manual are always available during mounting, setup and servicing. EUCHNER cannot provide any warranty in relation to the readability of the CD for the storage pe-riod required. For this reason you should archive a printed copy of the system manual. If you should lose the operating instructions or the system manual, you can download these documents from www.EUCHNER.de.
FunctionTogether with a handle module, the locking module makes it possible to lock moveable safety guards. The combination also serves as a mechanical door stop at the same time.
The following switch-on condition applies for the safety outputs OA and OB (see also System status table):
Safety guard closed
Bolt tongue inserted in the locking module
Locking arm in locking position
Both safety inputs (IA and IB) must be on
The locking module detects the position of the safety guard and the position of the bolt tongue. The position of the locking arm is also monitored.
The bolt tongue in the handle module is retracted and extended by actuating the door handle.
When the bolt tongue is fully inserted in the locking module, the locking arm locks the bolt tongue in this position. Depending on the version, this locking is by spring force or solenoid force.
Version MGB-L1-AR-...The locking arm is held in the locked position by spring force and is unlocked by solenoid force (closed-circuit current principle).
Version MGB-L2-AR-...The locking arm is held in the locked position by solenoid force and is unlocked by spring force when the solenoid is switched off (open-circuit current principle).
Warning!
The safety guard can be opened immediately in the event of interruption of the solenoid power supply!Usage only in special cases in accordance with strict evaluation of the acci-dent risk (see EN 1088:1995+A�:�008, section 5.5).
Typical case: If the risk of accidental locking inside a safety guard during a power failure is higher than the risk of ineffective guard locking.

Protection Against Environmental EffectsLasting and correct safety function requires that the system must be protected against foreign bodies such as swarf, sand, blasting shot, etc. which can become lodged in the locking and handle modules. For this purpose a suitable installation position should be selected.
Cover device during painting work!

Electrical ConnectionWarning!
In case of an error, loss of the safety function through incorrect connection.To ensure safety, both safety outputs (OA and OB) must always be evaluated.The monitoring outputs O1 ... O4 must not be used as safety outputs.Lay the connection cables with protection to prevent the risk of short cir-cuits.
Caution!
Risk of damage to equipment or malfunctions as a result of incorrect connec-tion.Do not use a control system with pulsing or switch off the pulsing function in your control system. The device generates its own clock signal on the output lines OA/OB. A downstream control system must tolerate these test pulses, which may have a length of up to 1 ms. The pulses are also present when the safety outputs are switched off. De-pending on the inertia of the connected device (control system, relay, etc.), this can lead to short switching processes.The inputs on an evaluation unit connected must be positive-switching, as the two outputs on the safety switch deliver a level of +�4 V in the switched-on state.All the electrical connections must either be isolated from the mains supply by a safety transformer according to EN IEC 61558-�-6 with limited output voltage in the event of a fault, or by other equivalent isolation measures.For use and operation as per the requirements, a power supply with the feature "for use in class � circuits" must be used. The same requirement ap-plies to the safety outputs.Alternative solutions must comply with the following requirements:a) Electrically isolated power supply unit with a max. open-circuit voltage of �0
V/DC and a limited current of max. 8 A.b) Electrically isolated power supply unit in combination with fuse as per UL�48.
This fuse should be designed for max. �.� A and should be integrated into the �0 V/DC voltage section.
All electrical outputs must have an adequate protective circuit for inductive loads. The outputs must be protected with a free-wheeling diode for this pur-pose.Power devices which are a powerful source of interference must be installed in a separate location away from the input and output circuits for signal pro-cessing. The cable routing for safety circuits should be as far away as pos-sible from the cables of the power circuits.To prevent EMC problems, it is imperative you follow section Notes on cable laying, page 16.
Important!
If the device does not appear to function when operating voltage is applied (e.g. green DIA LED does not flash), the safety switch must be returned uno-pened to the manufacturer.To ensure the stated degree of protection IP67 is achieved, the cover screws must be tightened to a tightening torque of 1 Nm.Tighten screw for the cover for the mechanical release to 0.5 Nm.
System Manual Safety System MGB-AR in Combination with a Locking Module
15
Safety in case of faultsThe operating voltage UB is reverse polarity protected.
The contacts IA/IB and OA/OB are short circuit-proof
A short-circuit between IA and IB or OA and OB is detected by the switch.
A short circuit in the cable can be excluded by laying the cable with protection.
Fuse protection for power supplyThe power supply must be provided with fuse protection depending on the number of devices and current required for the outputs. The following rules apply here:
Max. current consumption of an individual device Imax
Imax = IUB + IUA + IOA+OB
IUB = Device operating current (80 mA)
IUA = Load current of monitoring outputs O1 ... O4 (4 x max. �00 mA) + sole-noid + control elements
IOA+OB = Load current of safety outputs OA + OB (� x max. �00 mA)
Max. current consumption of a switch chain Σ Imax
Σ Imax = IOA+OB + n x (IUB + IUA)
n = Number of devices connected

Requirements for connection cablesCaution!
Risk of damage to equipment or malfunctions as a result of unsuitable connec-tion cables.On the usage of other connection components, the requirements in the fol-lowing table apply. EUCHNER provides no warranty for safe function in case of failure to comply with these requirements.

Information on operation in a CES-AR switch chainSystem timesThe locking module has longer response times than a CES-AR switch (see Technical data and diagram of Typical system times, Figure �0 and �1).
Position in a CES-AR switch chainThe locking module must be the last device in the CES-AR switch chain (see Figure 19).
Important: lay cables in a common harness
Figure 19: Position in a CES-AR switch chain
Output currentThe safety outputs on the guard locking module have a lower maximum output current than a CES-AR switch (see Technical data).
Number of devices in the switch chainsIn a pure MGB switch chain a maximum of ten devices can be connected in series. In mixed switch chains (e. g. together with CES-AR) the maximum number of devices is also reduced to ten.

Setup
Teach-in operationThe handle module must be assigned to the locking module using a teach-in func-tion before the system forms a functional unit.
During a teach-in operation, the safety outputs are in high-resistance state, i.e. the system is in the safe state.
Important!
The locking module disables the code for the previous handle module if teach-in is carried out for a new handle module. Teach-in is not possible again immediately for this module if a new teach-in process is carried out. The disabled code is deleted in the locking module only after a third code has been taught.The locking module can only be operated with the last handle module taught.If the locking module detects the learned or a locked handle during learning readiness, the learning readiness is ended immediately and the locking mod-ule enters normal mode or indicates a fault.If the bolt tongue is in the operating distance for less than 60 s, the handle module is not taught.
Teaching in handle moduleFit handle module.
Close safety guard. Check for correct alignment and distance using the mark-ing on the locking module and re-adjust if necessary.
Insert bolt tongue in the locking module.
Apply operating voltage to the locking module.
The green LED (DIA1) flashes quickly (approx. 10 Hz)
A self-test is performed during this time (approx. 8 s). After this, the LED flashes cyclically three times and signals that it is in standby state for teach-in. Standby state for teach-in remains active for approx. � minutes.
Teach-in operation starts, green LED (DIA1) flashes slowly (approx. 1 Hz). During teach-in, the locking module checks whether the handle module is a disabled handle module. Provided this is not the case, the teach-in operation is completed after approx. 60 seconds, and the green LED (DIA1) goes out. The new code has now been stored, and the old code is disabled.
To activate the handle module's code from the teach-in operation in the locking module, the operating voltage must then be switched off at the locking module for min. � seconds. As an alternative, �4V can be applied to the input RST for min. � seconds.
Mechanical function testIt must be possible to easily insert the bolt tongue in the locking module. To check, close safety guard several times and actuate door handle.
If available, check function of the escape release. It must be possible to operate the escape release from the inside without excessive effort.

Typical system timesReady delayAfter switching on, the unit carries out a self-test for 8 s. The system is ready for operation only after this time.
Risk time according to EN 60947-5-3If the guard locking is no longer effective, the safety outputs OA and OB on the locking module are deactivated after a maximum of �00 ms.
Difference timeThe safety outputs OA and OB switch with a minor time offset. They have the same signal state at the latest after a difference time of 10 ms.
Max. time delayFrom the control command to deactivate the guard locking to the shut down of the safety outputs the maximum delay is 500 ms.
Important!
The system times given are maximum values.

Troubleshooting
Latching fault when actuating the escape releaseIn order to achieve monitoring of the locking device in category 4, PL e according to EN ISO 1�849-1, an internal monitoring logic system is integrated into every locking module.
Result:: The MGB system enters into a latching fault when the escape release is actuated (see System status table on page ��).
Note!
The system might not enter into a latching fault if the escape release is actuated very slowly.
Fault resetProceed as follows:
Open the safety guard.
Switch the operating voltage off at the locking module for min. � seconds. As an alternative, �4 V can be applied to the input RST for min. � seconds.
The green LED (DIA1) flashes quickly (approx. 10 Hz). A self-test is performed during this time (approx. 8 s). The LED then cyclically flashes three times.
Close safety guard and switch guard locking on.
The system is in normal mode again.
