1. GENERAL INFORMATION

This manual describes the functions and operation of the iVISOR mentor QVGA load moment

indicator (LMI).

The purpose of the load moment indicator (below called the LMI) is to provide key information to the

operator of the loader which is needed for the operation of the loader within the operating ranges

specified by the manufacturer. The LMI provides the operator with information about the angle and

height of the boom, working radius, rated load and the actual load.

The iVISOR mentor QVGA load moment indicator comprises a central microprocessor unit with an

integrated display and operating console together with various sensors to record measured values.

The system components are connected via CAN bus.

The system works on the principle of a target / actual comparison. The actual value, resulting from the

pressure and angle measurement, is compared with the target values stored in the central unit’s

memory and analysed by the microprocessor.

If the crane nears its safe load limit, the system will warn the crane operator by means of both

acoustic and optical signals. In addition, as soon as the crane reaches an unauthorized operating

status, all crane movements will be switched off that would increase the load moment on the crane.

The manufacturer reserves the right to modify the contents of this manual without notice. Hirschmann offers no guarantee

whatsoever for this material, including guarantees with reference to commercial availability and suitability for particular

applications. Hirschmann shall not be liable for errors contained herein or for identical or consequential damages in connec-

manual may not be copied, reproduced or translated into another language, neither whole nor in part, without advance

written authorization from Hirschmann..

2. IMPORTANT NOTES

The LMI is an operating aid that warns the crane operator of imminent overloading or of the approach

of the hook block to the boom head, in order to avoid possible property damage or injury to personnel.

The device is not, nor is it intended to be, a substitute for good operator judgment and/or experience,

nor does it remove the need for utilizing only recognized safe procedures during crane operations.

The crane operator continues to bear ultimate responsibility for safe operation of the crane.

He must ensure that he fully understands and follows the displayed notes and instructions

in their entirety.

Before beginning crane operations, the crane operator must carefully read and understand

the entire manual in order to ensure that he is aware of the operation and limitations of both

the LMI and the crane itself.

Proper functioning is dependent upon proper daily inspection and observation of the

operating instructions set forth in the manual.

The LMI is not able to provide aid to the crane operator unless it has been properly adjusted

and unless the correct load capacity chart and the correct operating code have been

entered for the respective rigging configuration. The correctness of the LMI settings must

be guaranteed before beginning crane work in order to avoid damage to property and

severe or even fatal injuries to personnel.

This system can be equipped with an external key-operated switch located in the crane

operator's cab. This key-operated switch overrides control lever function switch-off by the

LMI or by the hoist limit switch system. This switch may only be used during emergency

situations, and even then only by authorized personnel. Failure to observe these

instructions could result in damage to property and severe or even fatal injuries to

personnel.

The LMI cannot perform correctly unless it has been properly adjusted. The prerequisite for this is

making conscientious and correct entries during the set-up procedure, in accordance with the actual

configuration of the crane. The correctness of the LMI settings must be ensured before beginning

crane work in order to avoid damage to property and severe or even fatal injuries to personnel.

3. SYSTEM DESCRIPTION

The iVISOR mentor QVGA load moment indicator system comprises a central microprocessor unit

with an integrated display and control console together with various sensors to record the measured

values.

Fig. 1: Components of the iVISOR mentor QVGA LMI system (without optional extras)

The system operates on the principle of reference/real comparison. The actual value is compared

with the calculated reference values and evaluated by the system. An overload warning signal is

triggered on the display and operating console once limit values are reached. All crane movements

that increase the load moment are switched off at the same time.

The crane-specific data specified by the manufacturer, such as load capacity charts, boom weights,

centers of gravity and dimensions, are stored in the central data memory. This data is the reference

information used to calculate the operating conditions.

The boom angle and length is measured by means of an length/angle sensor that is mounted on the

boom. The crane load is determined indirectly with the aid of pressure transducers.

The operating console is located in the operator's cab in plain view of the crane operator. All displays

and operating elements have background illumination for enhanced ease of recognition. The console

contains various operating elements as well as a multifunction LC display, all of which are described

in detail in chapter 3.2

The contrast of the LC display is adjustable manually in accordance with ambient light levels.

Introduction

3.1 System start

Upon switching on, the system boots and starts with an automatic test of the LMI system,

lamps and audible alarm. During the test, the LC display shows the start screen.

If the system was turned off for more than two hours, the setup configuration has to be

entered after the system test. (⇒chapter 4)

First, the operating mode is determined by an interactive step-by-step interrogation of the

rigging states.

Next is the interactive input of the reeving.

Now the LC display shows all inputs and awaits acknowledgment or cancelling.

Upon acknowledgment of the inputs the system is ready for operation.

In the event of a malfunction, a corresponding error code "E##" will appear on the Data

display (1). (> refer to error code table)

24 183 19 1012e (Generic) / 2009-02-26 / Rev. 01 / rk.

Data display (example w/o man basket):

Notes:

•If required, various symbols are displayed in the “status indication” field (refer to chapter 3.3).

•If required, active working area limits are displayed by the relevant symbols.

The relevant symbol flashes if the limit value is reached or exceeded.

•In the “function key symbols" field, the symbol allocated to the relevant function key appears.

Displays and controls

24 183 19 1012e (Generic) / 2009-02-26 / Rev. 01 / rk.

(2) Utilisation display (bar graph)

The Utilisation display (bar graph) indicates how much of

the admissible load moment (rated moment) is used. As the

rated moment changes constantly during loader operation,

the load moment display also changes constantly.

The utilisation display is marked with differently coloured fields:

green: "Safe” operation (0...90% of rated moment)

yellow: “Prewarning range” (90...100% of rated moment)

red: “Overload range” (> 100% of rated moment)

(3) “Pre-warning” light

When this amber display light comes on, this indicates that

the utilisation of the crane has reached the specified pre-

warning range. An overload situation could therefore be

imminent!

At the same time, the acoustic alarm sounds an interrupted

signal.

For the crane operator, this means that the work can

only be continued with caution.

(4) “Overload” warning light

This red display light lights up to indicate that the maximum

capacity has been reached or exceeded.

At the same time, the acoustic alarm sounds an

uninterrupted signal and, depending on the system wiring,

load moment-increasing boom movements are stopped.

By actuating the key the acoustic alarm can be

suppressed after a minimum 5-second warning.

Displays and controls

24 183 19 1012e (Generic) / 2009-02-26 / Rev. 01 / rk.

(5) "Hoist limit” warning light (A2B)

This red warning light lights up when the hoist limit switch

contacts open, i.e. when a hoist limit situation has occurred.

The acoustic alarm sounds and load-moment-increasing

crane movements are switched off at the same time.

A hoist limit situation occurs when the hook block

comes into contact with the boom head. The danger

exists in such situations that the hoist rope will

break, causing the load to fall. A hoist limit situation

could arise from the load being pulled against the

boom head or from the boom being extended or

lowered without the hoist rope being spooled off the

winch.

(6) “LMI bypass” warning light

This warning light flashes when the cut-out function of the

LMI system has been manually bypassed.

(7) “Hoist limit switch bypass” warning light

This red warning light lights up when the switch-off function

of the hoist limit switch has been manually bypassed.

Displays and controls

24 183 19 1012e (Generic) / 2009-02-26 / Rev. 01 / rk.

(8) Function keys F1 ... F4

Function keys with the allocated symbol.

During normal operation

(9) “Info” key

Key to bring system information and service menus.

Refer to chapter 5 and chapter 6.2.

(10) “SEL” key

Key to set up LMI system.

Refer to chapter 4.

(11) “LIM” key

Key to set up working area limits.

Refer to chapter 4.3

Displays and controls

24 183 19 1012e (Generic) / 2009-02-26 / Rev. 01 / rk.

(12) “Tare” key

The “TARE” key is used to display the net load on the actual

load display. The net load is the actual load less the lifting

gear and hook block. The “TARE” key must be pressed

before the lift process starts.

After actuation, the current load display is reset to zero (tared). After lifting

the load, the actual load display shows the net load (working load). Once

the working radius changes (due to a change of angle or radius), the

display changes back to the actual load and the tare function is ended.

NOTE: The actual load includes the load suspension device, the lifting

cable and all load limit stop equipment. The net load is the current load

without any load limit stop equipment. Display errors can be caused by

environmental factors, e.g. wind on the boom or load.

(13) “Alarm acknowledge” key

When this key is pressed, the acoustic alarm can be

suppressed after sounding for at least 5 secs.

After around 10 secs., the alarm sounds again if the reason

which triggered the alarm is still present.

The acoustic alarm sounds in the following cases:

System test, overload status, LMI system fault, and operating errors

detected by the system.

Displays and controls

24 183 19 1012e (Generic) / 2009-02-26 / Rev. 01 / rk.

3.3 Status displays

If required, various symbols are displayed in the “status area” of the data display (1).

Some of the symbols flash depending on the operating status.

LMI error in combination with a code (refer to error code list)

Constant: radius monitoring active Flashing: limit reached or exceeded.

Constant: height monitoring active Flashing: limit reached or exceeded.

Constant: boom angle monitoring active Flashing: limit reached or exceeded.

Constant: slew angle monitoring active Flashing: limit reached or exceeded.

Constant: virtual wall monitoring active Flashing: limit reached or exceeded.

Configuration Setup

24 183 19 1012e (Generic) / 2009-02-26 / Rev. 01 / rk.

4. Configuration SETUP

The configuration setup procedure allows the operator to input the crane configuration using

interactive displays.

The LMI cannot perform correctly unless it has been properly adjusted. The prerequisite for

this is making conscientious and correct entries during the setup procedure, in accordance

with the actual configuration of the crane. The accuracy of the LMI settings must be

ensured before beginning crane work in order to avoid damage to property and severe or

even fatal injuries to personnel.

The correct setting is of utmost importance for the proper functioning of the system and the

crane.

Therefore, only operators who are thoroughly familiar with the crane and the operation of

the system should execute this configuration procedure.

4.1 Interactive operation mode setup

It is necessary to setup the mode of operation of the LMI system every time the crane structure has

been changed or if the system has been turned off for more than 2 hours.

If the system was switched off, for example during short breaks (less than 2 hours), all adjustments

remain stored. When switching on again the system these adjustments can be acknowledged by

merely pressing the "Enter" key (provided that the crane configuration has not been modified!).

During the programming procedure the Load Moment Pre-warning Light (3) and the Load Moment

Limit Light (4) will light up and the aggravating crane movements will be interrupted.

The LMI programming procedure consists of the following steps (interactive operation):

•setting the boom type configuration

•specify jib / selecting man basket /

•setting outrigger configuration

•specify working range

•setting option: stowed jib operation

•setting hoist

•setting reevings

•confirming of inputs

For easy operation, the computer guides the operator through the procedure step by step.
