System Alarm Codes
Alarm Code 10 or 11 ( Rod Pressure Sensor)
This code is caused by the output voltage of the rod pressure sensor is lower (code 10) than
the minimum or higher (code 11) than the maximum voltage.
Actions to take; Fully retract the boom and lower the angle to zero degrees. Rod pressure
sensor is located inside the turret area on the control valve line. See figure 8.
1.
Using your finger lift the lock tab on the connector and switch the connector and see if
the code changes to the opposite sensor, if it does check the wiring from the display to
the sensor and check that air is not creating the code by bleeding the sensor or hydraulic
fluid is in the connector.
2.
Check the supply voltage and ground at the connector end. See figure 8. If the code
does not change and wiring is ok bleed pressure sensor or replace it.
3.
Supply voltage for pressure sensors is 15vdc, Output with no load should be around .50
to .70vdc
4.
Call for service if code is still present.
