Procedure 6.5 - 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 6.4.
Note:
On version 1 units manufactured prior to August 16, 1998 a single lift connector (J4) was used.
On subsequent units the lift motor wiring is in the J3 connector and the lift potentiometer wiring is
in the J4 connector. This text will use the connections used on current production units. For
version 1 units manufactured prior to August 16, 1998, convert the lift connections as shown:
CONNECTION 8/16/98 AND LATER
CONNECTION PRIOR TO 8/16/98
J3 terminal 1
J4 terminal 1
J3 terminal 2
J4 terminal 2
J3 terminal 3
J4 terminal 3
J4 terminal 1
J4 terminal 4
J4 terminal 2
J4 terminal 5
J4 terminal 3
J4 terminal 6
1.
If the lift motor will not move skip to step 7. If the lift motor moves and an error occurs
continue with step 2.
2.
Access the diagnostics program per Procedure 3.2 and proceed to the lift calibration portion
of the diagnostics program. If the lift calibration number is 0 or 255 skip to step 3. Operate
the lift, if the lift calibration number does not increment as the lift moves, skip to step 3. If the
calibration number increments as the lift moves, re-calibrate the lift per Procedure 5.3. If re-
calibration does not correct the problem, continue with step 3.
3.
Set the on/off switch in the “off” position. Using an ohmmeter, measure between terminal 1
(brown or green wire) and terminal 3 (orange wire) of the J4 connector on the lower PCA.
The measurement should be approximately 10 K
Ω
(or 1K
Ω
depending on manufacturer). If
the measurement is open (
∞
) or significantly high or low, replace the lift motor.
4.
Using an ohmmeter, measure between terminals 1 and 2 of J4 and measure between 2 and
3 of J4 on the lower PCA. The two measurements should total approximately 10 K
Ω
(or 1K
Ω
depending on manufacturer). If the measurement is open (
∞
) or significantly high or low,
replace the lift motor.
5.
If you have performed all of the above tests and an error still occurs when the lift motor
operates, there are three parts that could cause the problem. There are not any good tests
to check these parts other than substituting a known good part. They are lower PCA, ribbon
cable and upper PCA. Replace only one part at a time. If the new part does not correct the
problem, replace the original part.
