Start push button A start push button (NO) can optionally be connected into the feedback circuit. With the guard door closed, the enabling paths are then not closed until the start push button has been operated. If neither start button nor feedback circuit are connected, a jumper connection must be mounted between X1 and A1. If only one external relay or contactor is used to switch the load, the system can be classified in Control Category 3 to EN 954-1, if exclusion of the fault “Failure of the external contactor” can be substantiated and is documented, e.g. by using a reliable down-rated contactor. A second contactor leads to an increase in the level of security by redundant switching to switch the load off. ## Modification for 2 NC contacts: The safety monitoring module can be modified to monitor two NC contacts by bridging the terminals A1 and X2. The short-circuit recognition between connections then becomes inoperative. Expansion of enable delay time: The enable delay time can be increased from 0,1 s to 1 s by changing the position of a jumper link connection under the cover of the unit. The wiring diagram is shown with guard doors closed and in de-energised condition. The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix. ## **Documents** **Operating instructions and Declaration of conformity** (br) 426 kB, 12.07.2010 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/br/mrl_aes_1235_1236_br.pdf **Operating instructions and Declaration of conformity** (en) 752 kB, 02.12.2009 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/EN/mrl_aes_1235_1236_en.pdf **Operating instructions and Declaration of conformity** (jp) 1 MB, 30.11.2010 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/JP/mrl_aes_1235_1236_jp.pdf **Operating instructions and Declaration of conformity** (it) 661 kB, 02.12.2009 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/IT/mrl_aes_1235_1236_it.pdf **Operating instructions and Declaration of conformity** (fr) 918 kB, 02.12.2009 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/FR/mrl_aes_1235_1236_fr.pdf **Operating instructions and Declaration of conformity** (es) 662 kB, 02.12.2009 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/ES/mrl_aes_1235_1236_es.pdf **Operating instructions and Declaration of conformity** (pt) 678 kB, 11.05.2010 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/pt/mrl_aes_1235_1236_pt.pdf **Operating instructions and Declaration of conformity** (nl) 663 kB, 02.12.2009 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/NL/mrl_aes_1235_1236_nl.pdf **Operating instructions and Declaration of conformity** (de) 757 kB, 02.12.2009 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1235/bedien/DE/mrl_aes_1235_1236_de.pdf ## **Wiring example** (99) 20 kB, 22.08.2008 http://127.0.0.1/Bilddata/Si_baust/Aes1235/Schaltun/kaes1l41.pdf **Wiring example** (99) 20 kB, 22.08.2008 http://127.0.0.1/Bilddata/Si_baust/Aes1235/Schaltun/Maes1l11.pdf **ISD tables (Intergral System Diagnostics)** (en) 35 kB, 29.07.2008 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1135/ISD/i_ae2p02.pdf **ISD tables (Intergral System Diagnostics)** (de) 51 kB, 29.07.2008 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1135/ISD/i_ae2p01.pdf **BG-test certificate** (de) 531 kB, 05.01.2011 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1135/baumuste/z_135p01.pdf **BG-test certificate** (en) 513 kB, 05.01.2011 http://127.0.0.1/Bilddata/Si_baust/Pdf/Aes1135/baumuste/z_135p02.pdf ## **Images** Product photo Wiring example Wiring example K.A.
