3.2 DISPLAYING DATA AND MESSAGES

Follow the instructions in section 2.2 and 3.1
In order to identify the needfor a data adjustment, internally calculated data must be
compared with the actual measured data.
The DS 50 is an overload shut down system and is not classified as a scale. The
consideration of government specified tolerances is part of the trouble shooting
process. Crane and truck manufacturing tolerances do not allow calibrating an
overload shut down system with 0% tolerance.
To select the read out of geometrical data, load data and error messages press
the >H< key of the alphabetical key pad. The following information is now displayed.
Refer to drawing 3.2.1 to identify the displays described in the text below.
• Utilization of the lifting capacity in percentage. Overload cut off should be active
between 100% and 110%. The sample drawing 3.2.1 indicates an utilization of 84%.
• Maximum load capacity ( in lb/1000) for the actual boom position. The sample
drawing 3.2.1 indicates a maximum load capacity of 5,000 lb.
• Actual load on hook (in lb/1000). Note that the hook is not part of the load. The
sample drawing 3.2.1 indicates an actual load of 4,200 lb.
• Main boom length (in ft). The distance between the center of the boom pivot pin and
and the center of the sheave wheel pin.The sample drawing 3.2.1 indicates a
main boom length of 14.2 ft.
Refer to table below for fully retracted and fully extended boom length indication.
Crane model:
FMTV Cargo
FMTV Wrecker
• Main boom angle (in degree) in reference to the horizontal line. The sample drawing
3.2.1 indicates a boom angle of 65.5 degree.
• Radius (in ft.). Radius is defined as the distance between center line of crane rotation
and the center line of the load freely suspended. The sample drawing 3.2.1 indicates
a radius of 15.7 ft.
• In the event of a malfunction, an overload condition, or an out of loadchart condition,
the radius display becomes replaced by the Error message. Refer to the error code
list to decode the message.
