5、ect 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
6、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 thatstarting commands which cause hazardous
7、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
8、be performed on the machine in accordance withEN ISO 1849-1, Safety of machinery. Safety related parts of control systems. General principles for design, Annex BEN ISO 1411, Safety of machinery. Risk assessment. Principles.Correct use includes compliance with the relevant requirements for installati

Interlocking devices associated with guards. Principles for design and selectionEN 6004-1, Safety of machinery. Electrical equipment
10、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 devi
11、ces 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 dev
12、ice in a safe overall system. For this purpose the overall system must be validated, e.g. in accor-dance with EN ISO 1849-.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 shee
13、t applies in case of discrepancies with the operating instructions.System Manual Safety System MGB-AR in Combination with a Locking Module4Important!In the estimation of the PL for the overall system, a maximum value of 100 years can be assumed for the MTTFdaccording to the limit value in EN ISO 184
14、9-1:008, Section 4.5. This corresponds to a minimum value for the PFHdof .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 ca
15、se 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 function
16、s. Incorrect installation or tamper-ing can lead to fatal injuries to personnel.Check the safe function of the safety guard particularlyafter any setup workafter the replacement of an MGB componentafter an extended period without useafter every faultIndependent of these checks, the safe function of
17、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 t
18、his 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 allow
19、ed 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 inst
20、ructions and the system manualSystem Manual Safety System MGB-AR in Combination with a Locking Module5Important!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 moun
21、ting, 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
22、 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 OAand OB(see also System
23、status table):Safety guard closedBolt tongue inserted in the locking moduleLocking arm in locking positionBoth safety inputs (IA and IB) must be onThe 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 bo
24、lt 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-.T
25、he 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 curre
26、nt 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 insi
27、de a safety guard during a power failure is higher than the risk of ineffective guard locking.System Manual Safety System MGB-AR in Combination with a Locking Module6System overviewLocking module MGB-L1-AR-./MGB-L2-AR-.Figure 1: Locking module MGB-L1-AR-./MGB-L2-AR-.Handle module MGB-H-.Figure 2: Ha
