Introduction
The Greer Insight system is designed for use as an aid to crane operation.
Do not use this system without a properly trained operator who is knowledgeable in safety guidelines,
crane capacity information, and the crane manufacturer’s specifications.
This manual describes the operation of the Greer Insight, hereinafter referred to as the system. Please
read the contents and instructions contained in this manual.
Outline of Operation
The system is an aid to crane operation. 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.

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
measures the rod-side pressure and one sensor measures 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 operating area. These alarms are
programmable for each job site and allow the operator to work in a defined area.
•Minimum/Maximum Boom Angle Alarm
•Maximum Boom Length Alarm
•Maximum Tip Height Alarm
•Left and Right Swing Alarm
•Work Area Alarm
OUTRIGGER POSITION SENSING
This alarm alerts the operator, audibly and visually, when the selected outrigger position does not
match the detected outrigger position.

Power Up Self-Test
Immediately following system 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.
During this time, crane motions are disabled by the system function kick-out. Press the Press to
Continue button to acknowledge the home display message and allow the system to start normal
operation.
NOTE: Not all applications will have this screen. In such applications, the home display will be shown
without the need to select “CONTINUE”.
Home Display
The configuration display may be accessed from the home display by pressing the Configuration
button.

The Configuration Display
NOTE: The graphic above is only a representation of the system. The shaded areas may vary in
configuration depending on the application.
NOTE: Always check the point of lift and parts of line upon selection of the winch.
The configuration display gives a pictorial representation of the current system setup. Each shaded
area contains one or more green indicators and a button to change the setup selection. 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 main operation screen.
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 MAN button enables the optional Personnel Platform.
3. The POL button selects the current parts of line. Pressing the POL button will increment the
parts of line. 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 are no options available, the display will show “None”.
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 a 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”.

7. The WINCH group contains two green indicators, which indicate the selection of front or rear
winch. NOTE: If the crane is equipped with two winches, always select the winch to be used for
the lift, prior to selecting the parts of line selections for each winch.
8. The OUTRIGGER/TIRE selections are made by pressing the O/R button. NOTE: Some cranes
will not have the option of selecting different outrigger positions.
OUTRIGGER POSITION SENSING (IF EQUIPPED)
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.

The Home Display
1. The OUTRIGGER/TIRES setting contains four green indicators. They indicate the selection of
tires, full, intermediate, or retracted outriggers. The user must make the selection from the
configuration display. NOTE: OUTRIGGER/TIRE selections are dependent on the crane being
used.
