I'm going to guess that the picture shows an MCR of some sort. You would need to look at the prints/program for the entire cabinet to know what is supposed to pull that relay in.
It made me laugh when you said the electrician shoved the starter in and the motor ran. My guess is that they then told you that it's not their problem, and walked away. The best advice I can give you is to find out what kind of doughnut the electrician likes best, and make sure there are at least 3 of those in the big box of doughnuts you bring in for all the maintenance people. The problem you are having is troubleshooting 101, and the fact that the electrician isn't helping you is a good indication that you have either failed to impress, or worse yet pi$$ed them off. You need to make peace with the electrician. Free food for them and their co-workers is a good place to start. Also apologize for how you have acted, even if you have done nothing wrong. You are very new to this field, and so far haven't earned the respect that more experienced programmers/engineers would get. So you need to buy/bribe their pity and convince them that you deserve to be helped. Free food and a show of respect might just get you out of this jam.
