It seems that the diode idea would work. I have yet to attempt it in a lab setting so I will give it a try and let you know.
I am not sure about using pins 2, 5, 6 as they are just linked back to 4 or 3 so I think I have to make it work with the input ports available.
It seems that auxiliary switches are additional switches the manufacturer can add on for additional stopping points of the valve. Here is the description from the website:
"2 Extra SPDT Switches
The R4 Actuators come with 2 SPDT switches that are activated by cams that are pre-set to full clockwise and full counter clockwise. These are typically used to enegize indicator lamps to indicate the open and closed position of the valve being operated. The 2 extra SPDT switches operate using of 2 independent common voltages, and have adjustable cams to set the contact points at whatever rotation you want."
First figure out what the switches attached to pins 3, 4, 5 and 6 actually do at the ends of travel, and make a circuit that looks like the one with diodes (if possible). I suspect that the manufacturer's diagram is wrong, and the NO and NC labels associated with pin 3 need to be reversed.
It is very important that somewhere in the middle of the travel, both switches are closed (NC) as shown in the diode diagram. That way the motor can be moved both ways by simply reversing the current flow.
If you can open up the casing and get access to the "hidden" motor terminal, problem solved!
Take that risk if you want, I'm advising you not to because living on the edge of spec's usually ends in disappointment - its false economy anyway as you have a dual H-bridge and one motor, naturally you'd
parallel them up for better speed and lower losses anyway.
Hello,
So I have discovered a solution using 2 relays and an Arduino. This circuit would work with a single DPDT relay, however I did not have one that could handle the 24V of the motor and still be actuated by the 5V of the Arduino. So, I have a Solid State Relay that is activated by the Arduino, which then powers the coil of the DPDT relay and drives the motor. I have attached a schematic of my set up. Thank you everybody for the input!
