Contactor response time

I hope that didn't take 4 weeks haha

No it didn't as I was busy with other things in the meantime. I was not allowed to work on it everyday anyway.

Unfortunately it was too good to be true, now after a while it turns itself off again when the automatic cycle button is pushed (yellow pilot light briefly comes on then goes off). We have ordered service manual, maybe it will help to some degree.
When one of time delay relays are being tapped then it turns off the main 24 VDC supply contactor.

Received the wiring diagram with user manual not long ago. Seems like latching on automatic mode circuit is working. I think there might be some unrelated or unobvious cause, something is still in a semi-broken state.
Not sure if it's advisable to show the wiring diagram according to intellectual property law.

Another thing is there is missing NO K33.1 contact in series between K33 and K33.1 coils (wiring diagram incorporates three different models in one).

Thanks for answers everybody. Turns out one contactor was pressing too much against the time delay relay.
One link on the terminal block was bad as well.
