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 1849-1, Safety of machinery. Safety related parts of control systems. General principles for design, Annex B EN ISO 1411, Safety of machinery. Risk assessment. Principles. Correct use includes compliance with the relevant requirements for installation and operation, in particular EN ISO 1489-1, 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 6004-1, 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 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 sheet applies in case of discrepancies with the operating instructions. System Manual Safety System MGB-AR in Combination with a Locking Module 4 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 1849-1:008, 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 Warranty In 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 Instructions Safety 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 m。
