Ok, no problem. Will this be for both the bump and the Mom start?

You can use the existing bump switch as the new start switch.
The double relay board will work for the start relay unless you want to get just a single relay board, your choice.
Another bump switch option is adding another momentary switch in series so both buttons must be pressed to activate.

 

I think I'm following you. Never delt with the switch you mentioned so not sure how the bump would be wired up

 

Like this:
The diode is not really needed. The connections on the bump switched are assumed.
The only problem with this setup is if someone hits the bump switch while everything is running. That will kill the operation.
However I think there is a work around that would delay the start relay board dropping out for a second or two if the button was accidentally pressed.

 

I'll get that switch ordered and see how it goes. Really appreciate the help to all.

 

The circuit I was thinking of is already described by SJ in post #7. That will work quite well. To speed the process a bit you could add a small time delay to the release of the relay controlling that fast motor. OR use a liner PWM scheme to slow the fast motor as the beam starts to rise, so that it would keep loading for some additional time. A third motor to do an automatic unload could speed the process a bit more, at the expense of mechanical complications.

 

I haven't ordered the switch. Been in meetings. But I'm open to any and all suggestions.

 

Ok, you guys are going to make an electrical engineer out of me before it's over. Sad thing is I'm actually a Mechanical Engineer and at 52 yrs old, this stuff still gives me fits even back when I was back in college. Anyway, I added the single relay just for my visual so that I wouldn't get the 2 dual relay modules mixed up.

This is what I actually have and have on order.
1) main led lit switch to let him know that power is on to the system
2) 12v power is fed from main power switch to:
-MOM start switch
-SPDT Bump Switch (NO? is assumed that tab is NO and not NC, switch hasn't come in yet)
-12v to 5v converter
-Com ports on the Dual relay module
-Com port on single relay module
3) All grounds to ground
4) 5v top and bottom IR sensor triggers to dual relay module.
5) Dual relay module NC1 signal out to fast motor. (I had the two motors wiring backwards in previous drawing but confirmed correct locations last night.)
6) Dual relay module NO2 signal out to slow motor as well as Com on SPDT Bump switch.
7) NO output on single relay module to DC+ on dual relay module.

Ok I think I have a grasp on it but one thing I'm trying to understand. The Bump switch will trigger the single relay. I would assume this has to be a latching relay, because as soon as I release the button to trigger the relay, the relay will return to its natural state. So, once the relay is latched in, 12v power will then be sent through the NO signal port to the DC+ input on the dual relay module. Thus, sending power to both motors. Now the IR sensors will take over and trigger accordingly. Beam rises, bottom IR triggers no power to fast motor, beam continues to rise, top IR triggers no power to slow motor and no power to SPDT bump switch. Which therefore being tied into the NC SPDT tab, will break the circuit and kill power to the single latching relay. The only way power is restored is by pressing the MOM push start which re-latches the single relay and repeat the cycle.


Yes / No / kinda ??

I see the slow motor connected to NO2, should it be connected to NC2?
I would connect the 12 volts to the 5 volt converter after the main power switch.

I have it written down at home and forgot the paper. But it could be that I have the NC's and NO's backwards, but yeah it works. Yeah I'll send the converter power from the main on/off switch.

What about the trigger from the slow motor? Is my line of thinking correct?

What trigger exactly? Do you mean where the 12 volts on the slow motor connects to the bump switch? That part is wired correctly.

 

Sorry about that, should have been more specific. When the slow motor turns off, it kills power to the SPDT switch. By doing that, it kills power to the input trigger on the latched relay.

 

Yes that is correct.

 

Perfect, man can't thank you enough for your time.

 

(My response to post #27, first line): I hope that you learn to also create schematic drawings that show how systems work!!!
The wiring diagram is not so easy to follow.
The text description in #27 makes good sense, and should work, I think.

Thanks. Yeah I need to learn and understand the schematics.

You will find that usually a good schematic drawing will help a whole lot in understanding how a system functions. And since the major purpose of a schematic, after a system is built, is to assist in having it function correctly, understanding is very important. It is a lot like learning to read, at the beginning. The gateway to a whole another world.

In this particular situation since there are various modules involved a wiring diagram is suffcient.
