help me understand these symbols please.
help me understand these symbols please.
(OP)
I searched internet and this forum and could not find. The area marked red I do not understand what is going on.I have two "ice cube" relays with six connections each + the coil with all the wires pulled off.
I think the marked area is what I am looking for but I do not recognize this symbol.This is a commercial overhead door operator. As it is I push in the open contactor, it latches and cuts of when up. Push the close contactor it starts to close but relay will not latch. I let go it stops. Nothing happens when I push open, close buttons. I would very much appreaciate help with this. The relay is numbered, but not the drawing.

There's a phone number in the lower right corner. It says "Questions? Call Domino Engineering Corporation 800-736-6466"
You have the original drawing and may be able to see the nuber better.

Half full - Half empty? I don't mind. It's what in it that counts.
RE: help me understand these symbols please.
It was Saturday and no one would be available until noon my time today(Monday). I just through it out here hoping someone would recognize the symbol. I believe the bottom and top are normally closed contacts and the middle is normally open, just wanted to make sure. It seems to make sense with the exception I am unsure what is internal with the unit marked SRC which stops, reverse and closes the door if a switch on the bottom is made.(safety)
thank you again. I am opening and closing manually until noon, most likely.

It's a horrible drawing. I usually re-draw these rat's nest sketches into a proper drawing before I attempt to use them because the effort expended in doing so is more than compensated for by the cursing and bad temper which is avoided.
