The e-bx internal relay
is defective.
1.
Reset alarm by turning chair off and back on, making sure the
error does not reoccur.
2.
If error reoccurs, verify battery voltage. Refer to section 4.1.5.1.1,
Error! Reference source not found.
further. The code is displayed
if the if the voltage is lower than 17 VDC
3.
If the battery is too low, recharge it. Once fully charged, turn
chair off and back on.
4.
If battery voltage is good, verify both R-Net cable buses between
the R-Net power module and the e-bx.
5.
If both R-Net cable buses are properly connected and in good
condition, replace the e-bx controller.
6.
Once the e-bx has been replaced and the problem is solved, make
sure that power positioning modules do not jam and that all
actuators work properly throughout their entire range of
movement.
7.
If one of the actuators does not work or constantly stops its
movement, it is possible that this actuator, its cable, or its power
positioning module could be the cause for premature wear of the
e-bx. In this case, also replace the actuator, its cable or the power
positioning module components as required.

The actual voltage of
the 12-volt supply in
the e-bx
’s
internal
circuitry is too low.
1.
Reset alarm by turning chair off and back on, making sure the
error does not reoccur.
2.
If error reoccurs, unplug the
keypad’s cable
DB9 connector
(female) from the e-bx, then turn chair off and back on.
3.
If error does not reoccur, verify the condition of the DB9
connectors on the e-bx and the keypad
cable. There shouldn’t be
any trace of verdigris, any crooked or broken pins. Replace the
e-
bx or the keypad’s pushbuttons
as required.
4.
If error does not reoccur after disconnecting the cable from the
keypad and the DB9 connector are in good condition, properly
reconnect the DB9 cable back onto the e-bx and see if the error
reoccurs.
If it does, replace the keypad’s pushbuttons.
5.
If error reoccurs after disconnecting pushbuttons from keypad,
unplug all actuator extension cables from the e-bx, then turn
chair off and back on.
6.
If error does not reoccur, verify that actuator extension cables
and those of the e-bx are properly connected and replace
inconsistent or damaged parts if need be.
7.
Using a multimeter, reconnect, one by one, actuator extension
cables into the e-bx until error pops up. Disconnect from the e-bx
the cable causing error, but keep it connected to its actuator.
With the ohmmeter, measure the resistance between both
center female terminals on the extension cable. The ohmmeter
reading should be between 3.5 kOhms and 35 kOhms.
