17.6 ZERO-SETTING THE SLEW POTENTIOMETER
NOTE
: The only thing adjustable for the slew potentiometer is the zero point, which is complete when
the boom is at the 0
position over the front of the crane.
Defining the crane zero position:
The zero setting consists of defining zero-point offset. To define the zero-point or the slew
potentiometer the super structure must be positioned so the boom is in the zero degree position over
the front and the house lock pin engaged.
Using graphic console for zero-setting of slew pot potentiometer:
Press return until the slew adjustment screen is displayed.
The display shows a scale from
–10 to +10 degree, a horizontal mark shows the current position of
the slew pot wiper.
By pressing the “+” and “-“ keys simultaneously, the zero setting occurs automatically. Note: The
indicator line will move to zero on the bar graph.
When the operator is finished, pressing the ESC key returns the console display to normal.
