Hi All,
We have about 13Pcs of SMC3 installed which drive about 4 sets of motor each, the total motor load in each Softstart is within the SMC3 rating, the number of start stop for each smc is about 32 per hour, it is within the recomendation graph given by Rockwell, However from time to time we encouter SCR fault from different smc from within the 13 units. we install the filter as recomended by AB but it was not solving the problem, try putting the panel temp to 23deg but failed, I've raise this issue to RA tech but nothing concreate answer was given. remember that if the fault happen we can just push the reset and run again so basically its not a SCR fault. I've been asking this question to RA, When the SCR or at what instance the SCR fault happen. up to now we still having this problem.
if you have similar issue and you resolved it,please post..
Thank you very much..
