Several UCM inputs can be controlled in parallel if a common 0 V potential is present at OVM. 1.4 Operation on safety relay The MGB can be connected to most conventional safety relays.
MGB Help for Setup and Service 2 Troubleshooting 2.1 LED DIA 1 flashes 2 times (separate operation) Fault symptom: The MGB displays the fault state “input error (e.g. missing test pulses)”. Possible fault causes: 24 V DC missing at inputs IA and/or IB A safety evaluation unit or a safe control system with clocking outputs is connected. Remedy: 1. Check the wiring and correct it if necessary or switch the clock pulses off 2. Open the safety door 3.
