GENERAL INFORMATION
After satisfactory installation of the complete system, ensure that it is correctly wired in
accordance with the appropriate Wiring Diagram.
Before carrying out any crane
operations ensure that the
machine is on firm and level
ground and that the outrigger
beams and jacks are correctly
extended.
Throughout the procedure care
must be taken not to exceed any
structural or stability limits.
All attachments which can be
optionally stowed on the boom
during normal operation e.g. fly
and/or jibs must be removed prior
to calibration of the main boom.
Main boom calibration MUST be
completed before calibration of fly
and jib configurations.
Fly and jib configurations may be
calibrated in any sequence after
main boomcalibration.
Boom deflection correction is
optional but is recommended on
all configurations in order to
achieve the greatest accuracy.

CAL SWITCH
CALIBRATION PROCEDURES
The Display Unit provides the interface between the user and the calibration program. The user
communicates with the program interactively using the keypad. This manual provides information necessary
tocarry out a calibration but for the experienced user the displays provide information and data to enable the
calibration to be carried out using only on screen prompts.
Calibration procedures will only work with the CAL switch in the computer set to the CAL position. To gain
access to the CAL switch it is necessary to remove the cover from the computer assembly. The switch is
located near to the center of the computer board just between and below the ribbon cable connectors.

MicroGuard 404COMMISSIONING PROCEDURE FOR HYDRAULICCRANES
COMMAND 17 PERSONALITY
The Personality command is used to manipulate the crane calibration data.
The system has storage space for two sets of data in the EEPROM IC7. The active personality is the data
actually used by the main program. The second set of data is a "back-up" personality which is used to keep
a protected copy of the calibration data.
For convenience the sets of personality data are called:-
"A" the Active personality in IC7
"B" the Backup personality in IC7
Thecommandprovidesthefollowingfunctions;
display the status of the personality sets.
move data between the two sets
delete data from the active personality.
copy data to a back-up chip
retrieve data from a back-up chip.
When the command is first selected and after copying data, both "A" and "B" sets are checked for correct
check-sum. This is indicated by "good" or "bad" beside the respective reference in the lower display. Set
"A" is also checked against set "B". If the data is identical this is indicated by "same" or if not the same by
"diff". Moving of data is bymeans of sub-commands selected and a special [CAL] sequence. This requires
the entry of a code which is the same as the one used to enter the calibration routines and provides
adequate opportunity to abort the procedure. This isnecessary because some of the sub-commands cause
previously entered data to be irretrievably lost.
SUB-COMMAND 0 SAVE Saves "A" into "B". (B data is lost)
SUB-COMMAND 1 XCHG Exchanges "A" with "B" (data is not lost)
SUB-COMMAND 2 INIT Initializes "A" prior to new calibration.
SUB-COMMAND 3 BACK Copies the active calibration to a back-up chip.
SUB-COMMAND 4 RETR Retrieves the calibration from a back-up chip.
WARNING
POWER TO THE SYSTEM SHOULD BESWITCHED OFF BEFORE INSERTING OR REMOVINGANY
INTEGRATED CIRCUITS. FAILURE TO OBSERVE THIS PRECAUTION MAY CAUSE PERMANENT
DAMAGE TO THE SYSTEM OR ITS COMPONENTS AND RESULT IN THE LOSS OF CALIBRATION
DATA.

MicroGuard 404COMMISSIONING PROCEDURE FOR HYDRAULICCRANES
WARNING
If the system has been previously calibrated and the intention is only to access data or change only a
portionof the previous calibration then DONOT perform the initialization process which follows otherwise the
entire previous calibration data will be lost.

COMMAND 17/0 SAVE
On completion of a calibration it is necessary to carry out Command 17/0 SAVE and this is referred to at
the end of this publication. There is no reason, however, why this command should not be used at any time
during the intermediate stages of a calibration, for example at the end of a period of work or if desired after
each section of a calibration has been completed. The use of this command will ensure that a copy of the
calibration, up to the point of carrying out "save", will be contained in the back-upmemory.

NUMBER ENTRY
The MicroGuard 404 does not have number entry keys. A special number entry procedure is used to allow
the simple entry of numbers. When numerical entry of data is required the center display will change to
allow the entry of numbers. There are 5 categories in the display as follows;

SELECTS A DECIMAL POINT

SELECTS A DIGIT 0-9. THE AND KEYS
ARE USED TO CHANGE A NUMBER

THE ENTRY PROCESS
When the number entry is started the display isflashing on the number entry category and it is highlighted
by arrows pointing to the category.
Numbers are changed by use of the  and  keys. When the required number has been selected it is
entered by use of the SELECT key. Successive numbers up to a total of five digits may be entered in this
way. If a number requires a decimal point this is entered by moving the highlighted selection to the decimal
point by means of  .The decimal point then becomes highlighted.
The decimal point is entered by use of the SELECT key. After the selection of a decimal point the
highlighted flashing cursor returns tothe digits for the completion of the number entry. If a number requires
to be entered as a negative value the digits must be entered first followed by the change sign command.
Enter the number and then move the cursor to highlight the minus sign using  


Press SELECT to change to a negative value. If an error is made in the entry of data then move the cursor to
highlight the C using  


Press SELECT to delete the erroneous number. After entry of all digits, decimal point and sign changes,
move the cursor to E using  and press SELECT to enter the number and terminate the sequence.

COMMAND 05 ROPE
Maximum hoist rope tension is specified by the crane manufacturer for the size and type of wire rope
used on the machine. This value plus a 10% margin is entered in this procedure for each hoist.
Some regulations require that the maximum line pull is derated by a fixed amount per part of line and
this value may be entered in this procedure. Where no regulation exists then a value is not entered.
During the entry of rope data the maximum number of parts of line which could be used on the crane is
entered. This is not the actual parts in use at the time of entering data but is the maximum possible.
The position of the winch relative to the boom pivot is accounted for in the computations carried out by
the computer. This dimension is the horizontal distance from the boom pivot to the center of the hoist
drum. Where the winches are mounted on the boom or close to the boom pivot the distance will be
small but should still be entered.
In the following example of the use of this procedure the values used are:
Limit 0 (front winch line pull) 10,520 units
Limit 1 (rear winch line pull) 8,850 units
Max Parts 8
W0 (front winch position) 8.34 units
