General condition of the rail
1. Verify the general condition of the ceiling (damage, cracks)
2. Make sure the rail is level when it is not loaded.
3. Make sure that attachments (ceiling brackets, wall posts, wall brackets, rail
brackets) have not been displaced, damaged or removed.
4. Make sure rail joints are closed and that the spring pins are centered.
5. Check that the accessories (X-Y system, Gate, Exchanger, Turntable, Charging
station and PPP station) are complete and correctly maintained.
(Optional)
Perform a load test on track
with deflection measurement
when under load
1. Refer to section “Performing a Weight Load Test” (6-69), sub-section - Load
Test on Track with Deflection Measurment when Under Load.
2. Select the load at which the test shall be done: 100%, 125% or 150% of SWL.
3. Refer to weight load test form 001-11760-EN for acceptance criteria.

Associated to Malfunction
2: High limit switch fault
1. Check if the connector J10 (high limit) is connected to the main board.
2. Check that the wires and the terminals at the connector J10 are in good
condition.
3. Check the electric contact of the limit switches :
a. Disconnect the connector J10 from the main board.
b. Check the conductivity between the white and the green wire. (The
continuity status is short circuit when the strap end is out of the strap inlet,
and is open circuit when the strap end is in the strap inlet.)
c. Check the continuity between the red and the black wires. (The conductivity
status is short circuit when there is no tension on the strap, and is open
circuit when there is tension on the strap.)
4. Without any weight, press the Up button until the strap reaches the high limit
switch. If the high limit is not detected, inspect the limit kit.
5. Without any weight, press the Down button until the no tension limit stops the
action. If the down action is not stopped after 2 sec., inspect the limit kit.
6. Replace the limit kit if necessary (refer to section “REMOVING THE LIMIT
KIT”, page 6-44 and “INSTALLING THE LIMIT KIT”, page 6-46,
for procedure).
