Troubleshooting tips
5.
If error has disappeared, the problem was that the left stander actuator
had lost its position. By performing a position reset, the actuator has
recalibrated itself. In this case, replace the extension cable and the stander
actuator anyway, as this symptom indicates an intermittent problem.
3.
If the problem persists, refer to previous symptom (D) regarding a problem
with the seat elevate remaining in creep mode.
F
−
The chair equipped with a power tilt
and recline (regardless of power
options) moves forward and
backward without limitations.
−
The tilt and recline functions can
only move forward or can no longer
move because they are both
forward.
•
The tip limit
switch is
defective or not
adjusted
properly
•
One of the
connectors
between the e-bx
and the tip limit
switch is
disconnected.
•
A wire between
the tip limit
switch and the e-
bx is cut or
damaged.
•
The tilt or recline
actuator has lost
its position.
1.
Verify the setting on the tip limit switch
2.
If the setting is good but the problem persists, remove the tip limit switch,
and disconnected it.
3.
With a multimeter, check the electrical resistance between the two tabs of
the switch connector. Refer to images below.
a.
An infinite reading is needed on the ohmmeter when the head of the
tip limit switch points down.
b.
A reading below 0.9 Ohms is needed when the head of the tip limit
switch points up.
c.
Repeat these 2 previous steps several times in order the get a reliable
reading. If this result is not achieved, replace the tip limit switch.
4.
If the problem persists, check that the connectors between the tip limit
switch and the e-bx are properly connected and that the cables are in good
condition. Replace cables as required.
5.
If a multimeter is not available and adjusting the tip limit switch did not
solve the problem, replace the switch as well as the cable that connects it
to the e-bx.
6.
If the problem persists, fully retract the tilt forward and access the First
special boot-up mode. Fully recline the backrest and then fully retract it
forward. Turn chair off and back on.
7.
In a normal way, fully recline the backrest making sure it reaches its
maximum position without problems. If the backrest can recline, the
actuator and its extension cable must be replaced as this symptom
indicates an intermittent problem.
8.
If the problem persists, fully retract the backrest forward and access the
First special boot-up mode. Fully tilt the chair backward, then fully retract
forward. Turn chair off and back on.
9.
In a normal way, fully tilt the chair making sure it reaches its maximum
position without problems. If the tilt can move, the actuator and its
extension cable must be replaced as this symptom indicates an
intermittent problem.
10.
If the problem persists, replace the e-bx.
