  1. Yes A2 is negativ and A1 and A3 is positive, i was wrong about that because i did not have that contactor in front of me when i wrote it I just assumed. Before the turning of the engine (signal from A3 to A1 the engine would have been stopped by sensor so it wil have a "break" before change of signal. Engine is used to rotate a arm with a pipe, i have basicly 2 types of these. 1. big pipes and 3 pipes on one arm 2. small pipes and 24 - 32 pipes on one arm. this problem only happends on the small pipes with 24-32 pipes on it. why is this so? Is this because this engine wil have more movement (contactor would be used more) ? thanks for all the answear, i realy hope this wil help on my problem. i will certainly try it out . If this works out i wil reply here
  2. Thanks for the answear, Have a question about the diode and the contactor i use. Telemecanique TeSys® Model U – the ultimate starter-controller This is contactor i use, LU2B (reversing) this have A1,A2 and A3 (A1 is negative and A2 and A3 is positive). So i need 2 diode for this ? and connect between A1 & A2 and A1 & A3 ?
  3. Hello. I have a problem with the output on the IO-DI8-RO8 module. it seems like the output "hangs". Let say that the plc software is working perfecly, Connection is as follow: PLC -> EX-A2X -> IO-DI8-RO8 inputs and outputs wierd correctly, all working. Concerning the 1 output that hangs, the output control a contactor that runs on 24 + dc. contactor is used to make a small engine switch rotation. it seems that the plc is giving the signal to the IO module ( can see the light turn on the led) but the contactor is not responsing on the signal. either the output "hangs" or the contactor not responsing on the signal. Can this problem be bc getting spikes on the output everytime the contactor change the rotation of the engine ? BS Thomas
