Yes, unless it is documented, you would need to study the timing/sequence for the operation of the three contactors, and the various machine sequence it coincides with.
I don't think you have yet mentioned what type of mechanism/machine it is involved with?
I did a few posts back it is running mixing blades on a powder mixer
