FailSafe module does not request de-pacification

[VAU_RMA]

Hi. I have a problem with a FailSafe analog input module. module type: 336-4ge00-0ab0 Setup: Channels enabled: 1,4 Sensor evaluation: 1oo2 Sensor input: 0-4mA etc... Connection: Connected to a loop calibration (at the moment) Terminal 7: + Terminal 8: - (and a jumper to M) When I have wirebreak on one or both of the sensors, I get a red SF-LED, and red F1-LED / F4-LED. Also the Safety-LED is always green. When I have no wirebreak, all the red LEDs go off. There are no errors in the TIA-portal diagnostic window (for the module / channels). The QBAD is still TRUE (even though SF-LED is not on, or flashing), and I never get ACK_REQ --> I cannot de-pacifie the module. I have also tried to remove the 1oo2 evaluation (set to 1oo1), but the situation is the same. Any help would be appreciated :) Link to siemens forum post Edited July 9, 2014 by VAU_RMA
