ACCESS PROCEDURES TO µMACXxx
LOAD MONITORING SYSTEM (LMI)
This system has been conceived and developed to offer different levels of functionality of access to
internal data, according to the actions to be done; the following description explains these several
levels.
Starting from the basic level (Operator) some access levels are available, identified by three different
PASSWORDS; the first one given to the Technical Service Department and possibly authorized
Dealers (for troubleshooting and sensors replacement), and the second one given to the MANITOU
Technical Service Department only (for refined calibration), and the third one exclusively to
Authorised programming personnel (for Load Table and Machine Parameters programming), due to
the danger of wrong handling.
1°LEVEL:
OPERATOR:
Without needing a PASSWORD (also see OPERATOR MANUAL) all the working information of the machine
is available through system monitoring displayed by the display panel; starting from basic working data: lifted
load, max admitted load, outreach, working conditions, and tilting percentage.
By pressing the ENTER key it is possible to show other machine working data: boom angle and length.
By pressing ENTER again it will be possible to show the hydraulic pressure values at their 4 measuring
points,
(two on the main cylinder, and two on the compensation cylinder); Further pushing of the ENTER key gives
more information about transducers signals digital converted values, and about ON/OFF Inputs and Outputs.
The aim is to give to the Operator the possibility of reviewing these readings, allowing him to communicate
them to the Technical Assistance Department, giving relevant data, possibly avoiding a direct Service on
site.
The Operator can also find some information to solve easy faults in his OPERATOR MANUAL.
3
2° LEVEL: (1st PASSWORD) SENSORS REPLACEMENTS :
TECHNICAL ASSISTANCE DEPT. AND AUTHORIZED DEALERS
The second level corresponds to the information contained in this TROUBLE SHOOTING MANUAL,
where all details referred to system components are included (Main Unit, Transducers, Display Panel),
troubleshooting codes introduction, and the useful information to remove the problems without specific
tools (except a voltmeter).
For this level a 1st PASSWORD is given, allowing entry into all diagnostic functions and transducer
calibration (Angle and Length) in case of their replacement, without needing any PC or programming tool.
As far as Pressure Transducers are concerned, please note that they do not need any calibration, as they
are totally interchangeable.

BOOM LENGTH AND ANGLE SENSOR
CODE : CIT-1PICW1/xx
The boom and angle sensor is formed by a cable
reel with pulley on which a cable is wound; the
other end is attached to the boom head (or to the
first telescopic element in case of proportional
extension).
When extending the boom, the cable unwinds (max.
12 mt.) measuring the extension length signal
through a 10-turns servo potentiometer.
While using the machine, it is always necessary to
carefully survey the unwinding cable along the
boom, as it can be accidentally broken if it is
snagged or struck by external forces.
The replacement of this element has to be done by
Qualified Personnel only.
The angle sensor (inside the cable reel) detects the
absolute angle of the boom referred to the vertical
gravity reference thanks to a 1-turn servopotentiometer activated by a pendulum.
Analog signals from above potentiometers are used
by the LMI to compute the boom geometrical data.

PRESSURE TRANSDUCER
CODE : Y11 4740-350
The 4 Pressure transducers detect the pressure into the boom
lifting and compensation cylinders; typically 2 sensors are
required for measuring the differential pressure inside cylinders :
they must be installed on the two cylinder chambers to allow
differential pressure. By these values, weight computing is
achieved by the Main Control Unit.
These sensing devices detect the pressure by means of a
sensor, which transforms the measured pressure into a direct
voltage proportional to the pressure itself.
An on-board amplifier is included in the transducer itself.
Any replacement of these elements is very easy because they
are complete compatibility and must be done by Qualified
Personnel.

TROUBLESHOOTING
The first step to check a fault is to identify the problem which occurred with the machine
Operator.
Thanks to the auto-diagnostic procedures, which are able to recognise transducer failures, cable
breaking and internal electronic faults,alarm codes are automatically shown on the display to the
Operator, allowing him a certain capability of repairing, and also to better inform the Technical
Assistance even remotely.
When an alarm occurs, the LMI puts itself in a safe condition (shut down) blocking the dangerous
movements and, at the same time, the display shows the alarm corresponding message on the
display upper row.
Depending on the message, the fault can be identified.

ALARM CODE 1 : MEMORY DATA NOT RELIABLE
CAUSE:
All the calibration data is stored in the EEPROM 24C65 .
Through the “Check-sum” equation, software continuously checks the comparison with the original
memorised value. When detecting a difference, the display will show the following message:
ALARM 1 = memory data not reliable.
ACTION TO TAKE:
1) Switch the system off and on.
2) Verify that the EEPROM chip is fitted properly in its socket
(see also page 39-EPROM and EEPROM REPLACEMENT).
3) Re-enter data and save again, switch off and on again.
(To load data from the PC, please refer to the
“SAVING DATA TO A PC” section-pages 44-45).
4) If the problem persists, replace the PC board making sure that
software/parameters installed correspond to the
machine characteristics.

ALARM CODE 2 : ANGLE TRANSDUCER READING
LOWER THAN THE MINIMUM VALUE
CAUSE:
The signal from the angle transducer to the main PC board is lower than the minimum programmed value.
This can be produced by a short-circuit in the electrical wiring, between the Main Unit and Sensor or the
sensor itself is faulty.
NOTE: The Main Unit Processor identifies below and above the signal range a minimum zone and a
maximum zone in order to check the sensor.
ACTION TO TAKE:
Verify the cable reel PC board has the correct power supply ( refer to “CABLE REEL POWER SUPPLY
VERIFYING” section - page 28 ).

POTENTIOMETERS ALIGNMENT
Mechanical alignment of angle and extension sensors
Following the replacement of a potentiometer, even if this has been done carefully, it is recommended to
check its alignment.
The following procedure, if properly done, allows the total restoring of the machine behaviour without any
calibration operation.
Switch on the machine without load and wait for a few seconds for the main
working data panel monitoring on the display as shown here.
****
0.0 00.0 6.8
After that press the ENTER key a number of times until the page showing
the readings of sensors digital values is displayed.
With regard to the angle setting, it is simply necessary to check that in
horizontal (=°) positioning of the boom the reading of the sensor “AAAA” is
between 500 and 520 by rotating its body before fixing it, and that it
increases as the boom is raised.
For the extension after replacing the sensor adjust its screw to check that
reading on “LLLL” is about 50 and fix it.
Also, in case of cable replacement it is necessary to pre-tension
approximately 1 Mt. of cable-reel cable.
XXXX XXXX AAAA
LLLL XXXX XXXX
11
After the replacement of the potentiometer it is recommended to verify the correspondence of values shown on the
display into a couple of known positions of the boom.
I.E.: boom IN and boom OUT, or Boom lower position (Min Angle) and Boom Upper Position (Max Angle) .
These displayed values must correspond to the values given by the Manufacturer for this specific model of the
machine.

ANGLE AND EXTENSION SENSORS CALIBRATION-1st PASSWORD INTRODUCTION
To perform the self-calibration of sensors the 1st PASSWORD must be set.
The 2nd PASSWORD, which is reserved for the Manufacturer and to his Personnel authorised to modify the
programming, allows the refined calibration, selection of pre-programmed attachments tables and download of
new attachments tables.
The 1st PASSWORD code can be modified directly during calibration.
Switch machine on and wait for a few seconds until the first starting page shows up
on display as indicated here
Quickly press once ENTER key.
