Fairford synergy soft start unit

[Rocboni]

Yes but not in relation to the blower which you pointed out it has single point failure, my point is it does not require a second contactor, all the other motors have dual redundancy in the way of k10 and the individual DOL contactors.

The elevators and conveyors were moved from an existing plant and are circa 40 years old.

This thread is not about the requirement of 602041 or iso 13850, it is about the issue with the soft start.

Whatever, all one in the same.
The whole thing is a system, you can't split it up.
