1 Safty Tchniqu Multi-Function Safty Systm SAFEMASTER M Output Modul With Output Contacts BG According to - Prformanc Lvl (PL) and catgory 4 to EN ISO : SIL Claimd Lvl (SIL CL) 3 to IEC/EN Safty Intgrity Lvl (SIL 3) to IEC/EN Safty outputs can b assignd to on or svral function moduls (control unit or input moduls). Outputs: - 4 NO contacts - 3 NO contacts, 1 NC contact - 3 NO contacts 0-3 s dlay-rlas tim-dlay rlay - 2 NO contacts, 1 NC contact 0-3 s dlay-rlas tim-dlay rlay Prmanntly monitord fdback loop for xtrnal contact rinforcmnt LEDs for status indication Width 22.5 mm Circuit Diagrams Approvals and Markings Canada / USA Applications Ralization of fail-saf control circuits for protction of popl and machinry M8739 BG BG M8736 Gnral Information SAFEMASTER M Th maximum configuration of th SAFEMASTER M multi-function safty systm is as follows: th control unit BH 5911 up to 3 input moduls BG/BH 5913, or BG/BH 5914, BG/BH 5915 up to 3 output moduls BG diagnostic modul BG 5551 for CANopn, or 1 diagnostic modul BG 5552 for Profibus-DP Th BH 5911 controls th whol systm Th input/output moduls can b usd to xpand th control unit in a modular way into a multi-functional safty systm. BG M8738 BG M8740 To transmit status mssags of th individual moduls to a moni to ring or control unit, on of th following diagnostic moduls may b connctd: BG 5551 for CANopn BH 5552 for Profibus-DP Indication Grn LEDs and : Yllow LED "Run": on, whn th output contacts ar activatd on, whn th unit oprats without fault. Function rrors ar indicatd by flashing cods. Yllow LED "t": on, whil th dlay tim is lapsing. Only applicabl for dlayd outputs. All data in this list ar in corrspondnc with th tchnical quipmnt usd at th tim of this vrsion. W rsrv th right to implmnt tchnical improvmnts and changs at any tim n / 477

2 Stting of Functions Th instantanous output moduls ar controlld dirctly b th control unit; no sttings ar rquird. Th fdback input - must b linkd whn no fdback is rquird. With contact rinforcmnt by xtrnal contactors, thir forcibly guidd NC contacts must b connctd in sris btwn and. With th dlayd output moduls th output contacts ar activatd immdiatly. Whn th control signal is disconnctd th outputs switch off aftr th adjustd tim is lapsd (stting with 2 rotary switchs). whit LED "run" grn LED "" M2926_a plat M8933_a whit LED "t" grn LED "" Nots Sttings to th unit must b prformd by skilld prsonnl whil th unit is disconnctd.
