System Alarm Codes
Alarm Code 2 or 3 ( Angle Sensor)
This code is caused by the output voltage of the angle sensor is lower (code 2) than the
minimum or higher (code 3) than the maximum voltage.
Actions to take; Level the machine,
Fully retract the boom and lower the angle to zero
degrees using a angle finder
to determine zero degrees. All wire color is the
connection cable coming from turret. See figure 3.
1.
Remove the cover of the cable reel using a m3 allen wrench and check the +12.00vdc
(Typically the voltage is about 11.95vdc) supply voltage (Brown wire) and the ground
wire (white wire). See Fig 3. If the voltage is ok continue to step 2, if not check the
wiring from the cable reel to the display for damage.
2.
Check the 120 ohm resistor (with no power on) between the yellow and green wires
inside the cable reel (CAN BUS lines). If the wiring is ok, loosen the three screws (Fig
4) on the angle pot and adjust the pot until the display indicates what the angle finder
indicates. Check the high angle setting at 75 degrees for accuracy.
3.
If adjusting the angle pot and the angle does not change on the display, change the
angle pot and set the angle sensor by the display.
4.
Call for service if angle is still incorrect or to set angle sensor.
