Testing that the Sprocket Correctly Activates the Limit Switch
1. Field drill two (2) holes in bottom of chute position controller electrical box (A) large enough to
accommodate cables for power and Autoflow controls. Refer to wiring diagrams on Pages 19 and 20
to feed conduit for wiring to the main power breaker and Autoflow controls. (See Figure 4H.)
2. After wiring and before attaching the chain to the cable, test that the sprocket travels from the open
limit switch position to the close limit switch position. To test sprocket travel:
NOTE: For system to function when testing travel with the cover removed, the damper switch (B)
must be depressed.
a. Use tape to secure damper switch in the depressed position.
b. Ensure the sprocket (C) is in the open position when beginning testing. Use the manual dump
chute switch located on the main control panel to move between the open and closed positions.
Set the sprocket travel to the closed position on the Autoflow control and observe the bolts in the
sprocket (C) travel from the open (clockwise) position to the closed (counterclockwise) position
to the limit switch (D) as shown in
Figure 4H .
