Hi,
I have an ET200s reversing contactor installed within the siguard pmd-f1 and pm-x safety modules. I'm using a profibus DP network via im151-standard and a CPU315-2dp
I have the group diagnostics enabled and it all functions accordingly.
However, if i simulate a welded contactor (eg: push 3ph contacts in with screwdriver) the system fault LED lights up on the Contactor and also on the IM151 and on the CPU but the siguard unit doesn't fault..(should it??) i.e the pm-x infeed relay doesn't drop out thereby disconnecting the incoming 3ph.
Is this normal?
any help much appreciated
cheers
