DIN En60204 Section 1 / VDE0113 Section 1 (11/ 98) prescribes that power circuits with a safety function must be specified as per Section 9.4. In such safety circuits auxiliary contac-tors must intervene to guarantee re-dundancy so that, despite the occur-rence of a fault in one of the auxiliary contactors, the safety circuit remains operative. In every on -off cycle of the machine, the auxiliary contactors must be checked automatically at least once to ensure correct opening and closure of the contacts. Emergency-stop relay F127 fulfils this requirement – EN954-1 (3.97) – to the highest safety grade 4. There are models for manual Start (applicable for autostart-function) or for monitored-start-function available. The F127 may be used for single- or dual-channel operation with or without crossfault monitoringF
