Testing the System
Trolley Travel
This test requires two people. Each time the micro-limit switch is depressed the drive trolley should stop.
If the trolley fails to stop when the switch is depressed, re-check all electrical connections and 12V DC and
ground wire connections.
1. Press and hold the control switch UP button (Fig. 13A) to make sure that the trolleys (Fig. 7) travel
upward. If the trolleys travel downward, check the orientation of the 12V DC and ground connections
to the power pigtail (Fig. 9) Refer to Wiring Diagram (Fig. 14).
NOTE: The limit switches (microswitches) (Fig. 15A) are located behind the two small Phillips screws
(Figs. 15B) near the top and bottom of the vertical rail below the motor.

2. While running the system upward, toggle the upper microswitch with a stiff wire or large paper
clip (Fig. 16).
3. Check the lower limit switch in the same manner as in steps 2 and 3 while the trolley travels downward.
4. If the system fails to operate, check all electrical connections.
