Outline of Operation
The system is intended to aid the crane operator by monitoring the load and warning of an overload or
two-block condition. Crane functions are monitored by a variety of sensors.
The system compares the load suspended below the boom head to the crane capacity chart stored
within the computer’s memory.
At approach to overload, the system sends audible and visual warning signals. The system can be
configured to cause function kick-out by sending a signal to function disconnect solenoids.

•Computer Unit
•Pressure Sensors
•Swing Sensor
•Reeling Drum Assembly, with Extension and Angle Sensors
•Anti-Two-Block Switches

Display Unit
The display unit provides the operator with:
•Rated Capacity
•Actual Load
•Bar graph representation of Actual Load vs. Rated Capacity
•Radius of the Load
•Boom Angle
•Main Boom Length
•Working Area
•Crane Configuration
BOOM ANGLE SENSOR
The boom angle is measured by a potentiometer/pendulum assembly. It provides a voltage proportional
to boom angle. This sensor is mounted inside the cable reeling drum assembly.
EXTENSION SENSOR
The extension sensor provides a voltage proportional to the extension of the boom. The extension
sensor is mounted inside the cable reeling drum assembly.

PRESSURE SENSORS
There are two pressure sensors which measure pressure in the boom hoist cylinder. One sensor to
measure the rod-side pressure and one sensor to measure the piston-side pressure.
ANTI-TWO-BLOCK (ATB)
A switch monitors the approach of the hookblock or overhaul ball to the boom head. The switch is held
in the normal position until the hookblock or overhaul ball raises a weight that is mounted around the
hoist rope. When the weight is raised it opens the switch. The resultant switch open signal is sent to the
computer via the reeling drum. This results in the ATB alarm operating and a function kick-out to occur.
FUNCTION KICK-OUT
Electrically-operated hydraulic solenoids disconnect the control lever functions for boom hoist lower,
telescope out, and winch up when an overload or ATB alarm condition occurs.
OPERATOR PROGRAMMABLE ALARMS
These alarms, when properly set by the operator, define the working range. The operator can set the
minimum angle, maximum angle, maximum height, and maximum length.
These alarms are programmable for each job site and allow the operator to work in a defined area.
WORK AREA ALARM
This alarm permits the operator to define the operating zone by only two set points. The use of this
method results clearly defines the operating zone.
OUTRIGGER POSITION SENSING
This alarm alerts the operator, audibly and visually, when the selected outrigger position does not
match the detected outrigger position.
SWING SENSOR
This measures the angle of the boom relative to the chassis.

Power Up Self-Test
Immediately following electrical power up, the system executes a system self-test which lasts for
approximately 10 seconds. During this time the display shows the rating chart number, units in use, and
load.
After the startup screen, the Crane Configuration page will display.

Home Display
NOTE: The Configuration Display may be accessed from the Home Display by pressing the button
show above.
The system has the capability to remember the last configuration. When removing power to the system,
and re-powering, the settings remain intact until reset by the operator.

The Configuration Display
The Configuration Display gives a pictorial representation of the current system setup. Each shaded
area contains a group of one or more green indicators and a button to change the setup selection,
depending on the application. In groups with multiple options, green indicators illuminate individually to
indicate the selection. When the configuration is complete, press the Home button to return to the
Home display.
NOTE: Always check the point of lift and parts of line upon selection of the winch.
WARNING!!
THE DISPLAYED LOAD AND CAPACITY ARE BASED UPON THE CURRENT SELECTED
POINT OF LIFT. NEITHER THE GREER INSIGHT SYSTEM, NOR THE CRANE CAPACITY
CHART ALLOWS FOR LIFTING FROM MORE THAN ONE HOOK AT A TIME.
1. The HOME button will return the user to the Home display.

2. The OUTRIGGER selections are made by pressing the button circled. NOTE: Some cranes will
not have the option of selecting different outrigger positions.
OUTRIGGER POSITION SENSING (IF EQUIPPED)
At power up, the system will read the OPS sensors and select the corresponding chart. It
will display a white arrow above the corresponding outrigger position on the screen.
The operator will be warned if the selected outrigger position does not match the
detected outrigger position.
Correct Selection: The selection will have a solid green indicator, when the selected
and detected outrigger positions match.
Incorrect Selection:The detected position will flash a red indicator and the selected
position will be a solid yellow indicator. On the main screen, an audible alarm will sound
if the selected position is greater than the detected position. The alarm will sound if the
operator has selected fully extended outriggers, but the outriggers are in the
intermediate or fully retracted position.
3. The PARTS OF LINE (POL), button selects the current POL. Pressing the POL button will
increment the POL. When the maximum parts of line for the equipment being used is reached,
the indicator will rollover to one POL.

4. The JIB OPTIONS may be selected by pressing the jib button multiple times to scroll through
the jib options. If there aren’t any options available, the display will show “None”. NOTE: The jib
must be stowed before it is erected.
5. The PICK LONG, PICK SHORT, PICK MAIN selections are dependent upon the model of
crane being used.
6. The STOW (STOWED JIB), group contains one green indicator. This will illuminate when the jib
is stowed on the boom. Press the Stow button multiple times to scroll through jib options. If
there are no options available, the display will show “None”.
