Configuration Setup

1. GENERAL INFORMATION

This manual describes the service menus of the iVISOR mentor QVGA load moment indicator (LMI)

and assists a service or maintenance person in identifying system malfunctions.

NOTE: Knowledge of system and CAN bus wiring is assumed. REFERENCE: Refer to Operator’s manual 24 183 19 1012e (Generic) for detailed operation of

the mentor QVGA.

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. The system components are connected via CAN bus.

Components of the iVISOR mentor QVGA LMI system

Configuration Setup

Components:

CPU/Console: 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 iVISOR mentor QVGA displays all geometrical information such as length and angle of main boom, working radius and tip height of the boom. It also displays the actual load and the maximum load permitted by load chart. Furthermore, it has an acoustical alarm, a warning light for overload, and a pre-warning light. The graphic display allows for a simple interactive configuration setup, as well as sensor calibration (zero adjustment), and troubleshooting sensor output screen. The console has a warning light for anti-two-block conditions and an override switch for overload or antiblock condition.

Length-Angle Transducer: The length-angle sensor gSENS LWG, often referred to as

the “cable reel”, is a combination of two transducers in one box, installed on the base section of the boom. It measures the length and the angle of the boom. A reeling drum drives a potentiometer, which is the length transducer. Part of the length transducer circuit is the length cable on the drum, which is a multi-conductor cable. It is connected to the anti-two-block switch at the boom head and to a slip ring body in the LWG. The angle transducer is a potentiometer driven by a weighted pendulum that is oil damped. Both length and angle transducer are connected to a CAN bus controller board, which is connected to the bus system.

Pressure Transducer(s): A pressure transducer pSENS DAVS converts hydraulic

pressure into a CAN signal. One (or two) pressure transducer is (are) connected to the piston side of the lift cylinder and one to the rod side.

Slew Angle Sensor: The gSENS DW G sensor converts the circular motion of the upper

structure of the crane into a CAN signal.

Configuration Setup

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.

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.

Sensor Calibration

3. Sensor Calibration

In this code-protected area, settings affecting system precision can be made by trained service personnel. For access to the calibration menus it is necessary to input a matching 5-digit code.

To start the function:

▼ Info screen

Actuate the INFO key.

to service menus

back

▼ Entry to calibration menus

abort input of service code

increase marked numeric value

reduce marked numeric value

mark the next figure, access after the last valid figure

If an invalid service code is entered, you are prompted to enter it again or to abort the input.

Sensor Calibration

After entering the service menu you can follow the calibration procedure step by step or can select the type of calibration by scrolling with function key

. Press "ESC" to finish calibration procedure:

3.1) pressure signal piston side

… and rod side 3.2) slewing angle

signal

3.3) boom length signal

3.4) boom angle signal

Sensor Calibration

3.1 Zero-setting the pressure signals

NOTE: The only thing adjustable for the pressure transducers is the zero point, which is the signal the

transducer outputs when there is no (zero) pressure sensed.

Ensure there is no pressure in the hydraulic line when

disconnecting the hoses from pressure transducers!

The display shows which transducer (piston-side, rod-side or force) is being zeroed and a horizontal dial marks the present pressure (or force) difference in %.

NOTE: there are two

calibration screens: for piston and for rod transducer.

NOTE: The operating range for zero-setting this value is from -1% to +1%. Press and release the “AUTO >CAL<” key multiple times until the zero-setting starts.

The indicator line must move to zero on the dial, otherwise the zero-setting of this value is not correct!

▼ Zero point adjustment, pressure piston side:

leave the service menu

24 183 69 1012e (Generic) / 2009-02-26 / Rev. 01 / rk.

carry out zero point setting
