8.
Monitor terminals 1 and 3 (yellow and black wires) of lift power connector. Enter the manual
program and press the
INCLINE
T
key. The measurement should be approximately 120
Vac (line voltage). If the voltage is present and the lift motor moves normally skip to step 13.
The voltage will only be present until such time as an error occurs. If line voltage is
measured but the motor does not move, replace the lift motor.
9.
If the upper display does not indicate that the lift is moving in both directions when the
appropriate
INCLINE
key is pressed the problem is either the upper PCA, or the keyboard
(display housing). Troubleshoot the keyboard per the keyboard portion of Procedure 2.1. If
the keyboard is good, replace the upper PCA.
10. If the upper display indicates that the lift is moving in both directions when the appropriate
INCLINE
key is pressed, the problem is either the upper data cable, lower data cable or the
lower PCA. There are not any good tests to check these parts other than substituting a
known good part. Replace only one part at a time. If the new part does not correct the
problem, replace the original part
11. If you have performed all of the above tests and the lift system is still not functioning, call
Precor Technical Support.
