4 WHAT’S WRONG?
So, what’s wrong? Assuming you are reading these pages because of some kind of problem with the
PAT system, let us try to guide you quickly to solving the problem. In most cases, your problem will
fall under the following categories:
4.1 I HAVE AN ERROR CODE INDICATED ON THE CONSOLE
Please go to section Error Codes!
4.2 THE DISPLAYED ANGLE DOES NOT MATCH THE ACTUAL BOOM ANGLE
Start in section Angle Sensing to check the indicated angle.
4.3 THE DISPLAYED LENGTH DOES NOT MATCH THE ACTUAL BOOM LENGTH
Start in section Length Sensing to check the indicated length.
4.4 THE DISPLAYED SLEWING DOES NOT MATCH THE ACTUAL SLEWING ANGLE
Refer to section Slewing Sensing to check the slew sensor.
4.5 THE DISPLAYED LOAD DOES NOT MATCH THE ACTUAL LOAD
Please note that the indicated load is calculated by the system from the geometry information in the
computer, the operator’s selections, and all the sensor inputs. If the load display is off, it can therefore
be due to an error in any or several of these inputs! Refer to section Load sensing to narrow down the
source of your problem.
4.6 THE CONSOLE DISPLAY IS BLANK
If the console does not show any sign at all (no lights, no buzzer, no display), the problem is either in
the wiring between console and central unit, or the console itself. Refer to section No console display
for further troubleshooting.
4.7 I HAVE AN A2B PROBLEM
Please go to sectionA2B PROBLEM
4.8 I HAVE A CAN-BUS PROBLEM
Please go to section CAN-Bus Communication!
4.9 I NEED TO IDENTIFY A SPARE PART
Please go to the Spare Part Listings!
