ONE OR MORE FUNCTIONS HAVE STOPPED FUNCTIONING
1.
At this point, one of three possible components may have failed: the control box, the actuator /
motor, or the pendant.
2.
Access the control box in the base of the chair.
3.
Refer to the control box wiring diagrams by following this link: “
Control Box Wiring
”.
4.
Determine the ports on the control box that operate the functioning and non-functioning sections of
the chair.
5.
Switch the plugs in these two ports
•
Example for KOM control box: if the back section of the chair is not working and the leg section
of the chair is working, switch the cords in ports #2 and #3.
6.
The buttons on the pendant will now be switched. The buttons that controlled the non-functioning
portion of the chair will now be controlling the functioning portion of the chair.
•
Following example from step 5: the buttons for the back section on the pendant will now be
controlling the leg section and the buttons for the leg section will now be controlling the back
section.
7.
If the motor is now working, then you have eliminated the motor as the possible failed component.
8.
If the motor is still not working, then the motor has likely failed and may need to be replaced. If this
is an X-Series chair built prior to February of 2012, additional troubleshooting can be done by
following this link:

.
If this is not an X-Series chair built
prior to 2012, visit
the
Technical Assistance & Parts page
of our website or contact 0ur

Service Department
for the appropriate part number and / or pricing.
9.
If the motor is not the failed component, then the issue is either the control box or the pendant. If
another pendant is available, plug it into the control box of the non-working device to test the
functions. If the alternate pendant is still not working or if another pendant is not available, a
replacement pendant and control box may be purchased together. Unused items may be returned
for a refund (please refer to section 6 of
Winco Mfg., LLC’s Terms & Conditions
.)
10.
Once the item(s) are received, plug the new pendant into the control box and test the functions of
the stretcher-chair. If the replacement pendant did not resolve the issue, remove and replace the
control box. Control box installation and maintenance instructions should be included with the new
control box. If the instructions are not available, you may download a copy via the
Product
Resources Page
of our Website or by contacting our
Customer Service Department.
