Procedure 5.4 - Troubleshooting the Lift System
Note:
The lift motor is disabled when the EFX is not being used. The speed sensor must detect motion
in order for lift operation to be enabled. In the following procedures, when lift motor movement is
being tested the stairarms must be in motion. Before performing this procedure, ensure that the
speed sensor is operating normally per Procedure 5.3. The lift motor is connected to the lower
PCA via two cables. The lift motor connects to a cable that goes to the mid point of the frame
where it connects to another cable that completes the path to the lower PCA. The cables will be
referred to the forward and rear lift motor cables, respectively.
1.
If the lift motor will not move skip to step 10. If the lift motor moves and an error occurs
continue with step 2.
2.
Set the on/off switch in the “off” position. Disconnect the lift motor cable from J6 of the lower
PCA.
3.
The following measurements will be measured on the connector that was removed from J6
of the lower PCA in step 2. Using an ohmmeter, measure between terminal 4 (brown) and
terminal 6 (orange wire). The measurement should be approximately 1K
Ω
. Measure
between terminals 4 and 5 (blue wire) and measure between 5 and 6. The two
measurements should total approximately 1 K
Ω
. If any of the measurement are open (
∞
) or
significantly high or low, continue with step 4. If all three measurements are correct, skip to
step 8.
4.
Remove the four bolts that fasten the rear and forward halves of the frame together and
carefully separate the two frame halves. Disconnect the rear lift motor cable from the
forward lift motor cable.
5.
The following measurements will be measured on the forward lift motor cable connector.
Using an ohmmeter, measure between terminal 4 (brown) and terminal 6 (orange wire). The
measurement should be approximately 1K
Ω
. Measure between terminals 4 and 5 and
measure between 5 (blue wire) and 6. The two measurements should total approximately 1
K
Ω
. If any of the measurement are open (
∞
) or significantly high or low, continue with step 6.
If all three measurements are correct, replace the rear lift cable
6.
Remove the six screws that fasten the front cover halves together. Remove the front half of
the front cover. Disconnect the forward lift motor cable from the lift motor cable.
7.
The following measurements will be measured on the lift motor cable connector. Using an
ohmmeter, measure between terminal 4 (brown) and terminal 6 (orange wire). The
measurement should be approximately 1K
Ω
. Measure between terminals 4 and 5 and
measure between 5 (blue wire) and 6. The two measurements should total approximately 1
K
Ω
. If any of the measurement are open (
∞
) or significantly high or low, replace the lift
motor. If all three measurements are correct continue with step 8.
8.
If you have performed all of the above tests and an error still occurs when the lift motor
