2. If the trolley motor is not audible:
a. Check the motor and voltage to the motor. If voltage is present, replace the motor (6390-101-132).
b. Check the motor and voltage to the motor. If voltage is not present, replace the motor cable (6390-101-431) or the
control board assembly (6390-101-014).
c. Run the lifting arms down using the trolley control panel. If the product lowers, communication may be the problem.
Check both sides of the communication link. Replace the communication boards (6390-001-378 or 6500-002-100)
as necessary.
3. If the trolley control panel LED error indication is illuminated, contact Stryker Technical Support for advanced
troubleshooting.
