COMMAND 05 SWING
Perform this Command
ONLY
if the crane has a swing potentiometer.
Command 05 includes the scale, zero, and direction routines. These routines are usually carried
out consecutively. However, zero and direction can be done in isolation of scale.
When scale is redone, zero and direction must follow.
SCALE
Command 05 does not require the entry of measured data. Measurements of swing data are
acquired automatically during the calibration of the swing sensor.
However,
it is essential that
the crane upper be rotated slowly during this procedure
.
ZERO
To obtain the data required for the zero of the potentiometer, the
crane upper must be directly
in line over the front of the crane.
This applies to
all
crane models, lattice or hydraulic and
truck or all terrain.
DIRECTION
Swing direction is similar to a compass. Swinging to the right increases the readings and
swinging to the left decreases the readings. If the swing potentiometer is mounted so that output
is in the wrong direction, use the direction command to change the displayed direction.
