Dear experts,

i have a question for you in the form of a red key in my  system for motor which is currently running. ON/OFF commands and Running/Ready feedbacks have been tested for the motor. Even though I can control the engine from the Faceplate and the system does not give me any alarm, the red key remains. My question is, do you know how to remove it or can you help me explain its presence ?

In the attachment, I am sending 3 photos in one: about the status of feedback messages, MotL (motor  block) and FP for motor display.

I don't see any problem in the control function or incoming errors, maybe you can tell me more.

Thanks for any ideas and advice.

Hi Dusacek,

The litle wrench is the visualitation of the ST_Worst signal, output of the MotL block.

For MotL the ST_Worst is determined by:

• LocalLi.ST
• StartLocal.ST
• StopLocal.ST
• Trip.ST
• FbkRunOut.ST
• AV_Out.ST
• StartChn.ST
• StartAut.ST(only ifFeature2.Bit10= 1)
• StopAut.ST(only ifFeature2.Bit10= 1)

Please check the signal ST_Worst and the other signals.
Hope this helps.

With best regards,

Cedric
