Special Jack Error Codes on OneControl Touch Panel or OneControl App
To clear the error codes listed below:
1. Correct or otherwise repair the issue (see the table below).
NOTE: In order to clear the special jack error code the jacks need to be “homed.” In order to “home” jacks,
each jack must be able to retract a minimum of 6”.
NOTE: The Power Tongue Jack does not need to be “homed.” The Power Tongue Jack cannot be operated
from the OneControl Touch Panel or OneControl App while clearing the special jack error codes.
The Power Tongue Jack can be operated using the “RET/EXT” switch on the tongue jack during this
procedure.
2. Extend all jacks to reach the 6” of minimum retract needed.
A. Press “EXTEND” and “FRONT” to extend the front jacks (if required).Refer to “Operation -
OneControl Touch Panel” and “Operation - OneControl App.”
B. Press “EXTEND” and “REAR” to extend the rear jacks (if required). Refer to “Operation - OneControl
Touch Panel” and “Operation - OneControl App.”
3. Press “ENTER” to AUTO RETRACT. The jacks will retract until they reach the hard current limit. The
Power Tongue Jack will perform an automatic grounding during the AUTO RETRACT sequence.
4. The jacks are now “homed” and the special jack error code will be cleared.
