8. Remove the lift power connector from the lower board. Using an ohmmeter, measure
between terminals 1 and 2 (white and red) between terminals 1 and 3 (black and white) and
between terminals 2 and 3 (red and black). The measurements should be approximately
14.7Ω, 14.3Ω and 29Ω, respectively. If any of the measurements are significantly low,
replace the lift motor. If any of the readings are open (∞) or significantly high, check the lift
motor cable and connectors. Repair any wires or connections that are bad. If the cable and
connectors are good, replace the lift motor.
9. Re-insert the lift power connector in the lower PCA. Set the on/off switch in the “on” position.
Using an AC voltmeter, monitor the voltage between terminals 1 and 2 (white and red wires)
of the lift power connector. Enter the manual program and press the CROSSRAMP
key.
The measurement should be approximately 120 Vac (line voltage). If the voltage is present
and the lift motor moves normally, skip to step 10. The voltage will only be present until such
time as an error occurs. If line voltage is not present skip to step 11. If line voltage is
measured but the motor does not move, replace the lift motor.
10. Monitor terminals 1 and 3 (white and black wires) of lift power connector. Enter the manual
program and press the CROSSRAMP
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.
11. If the upper display does not indicate that the lift is moving in both directions when the
appropriate CROSSRAMP key is pressed the problem is either the upper PCA, the
keyboard (display housing). Troubleshoot the keyboard per the keyboard portion of
Procedure 2.1. If the keyboard is good, replace the upper PCA.
12. If the upper display indicates that the lift is moving in both directions when the appropriate
CROSSRAMP key is pressed, the problem is either the upper interconnect cable, lower
interconnect cable and 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
13. If you have performed all of the above tests and the lift system is still not functioning, call
Precor Technical Support.
