It's difficult to figure out without seeing how the rest of the terminal block is wired.
This is my first time trying to draw ladder logic in ASCII...
Momentary to open and close:
From this I'd suggest wiring the terminal block as such:
<--- [/]STOP ---+---+--- UP ---+--- [/]LS-UP --- (/)DN --- ()UP --->
| +--- ()UP ---+
+---+--- DN ---+--- [/]LS-DN --- (/)UP --- ()DN --->
+--- ()DN ---+
Connect C2 and C4
Connect C31 and LS3
Connect LS2 and E2
Connect C32 and LS4
Connect LS1 and E1
Connect the Stop switch between C and C2/C4
Connect the Up switch between C2/C4 and C31
Connect the Down switch between C2/C4 and C32
I'm working on the assumption that LS2/LS3 is fully open and LS1/LS4 is fully closed,
and that the guy who designed this used those stubby golf-ball sized crayons.
