COMMAND 00 RUN
Following correct entry of the calibration code, the System will be in the MONITOR mode and will be at
Command 00 Run. Execution of this Command will cause the System to carry out a System Self-TEST followed
by a return to the working screen.
COMMAND 01 PERSONALITY
COMMAND 01 PERSONALITYCOMMAND 01 PERSONALITY
COMMAND 01 PERSONALITY
Command 01 Personality is used to manipulate the crane calibration data.
The System has storage space for two sets of data in the EEPROM IC7. Active Personality is the data actually
used by the main program. Back-up Personality 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
Command 01 provides the following functions:
♦Displays the status of the personality sets.
♦Moves data between the two sets
♦Deletes data from the active personality.
♦Copies data to a back-up chip
♦Retrieves data from a back-up chip.
When Command 01 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;" if not the same, by "diff." Moving
data is by accomplished by means of the sub-commands selected and a special [CAL] sequence. This requires
the entry of a Code that is the same as the one used to enter the calibration routines and provides adequate
opportunity to abort the procedure. This is necessary 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 (A data is lost).
SUB-COMMAND 3 BACK Copies the active calibration to a back-up chip (data is not lost).
SUB-COMMAND 4 RETR Retrieves the calibration from a back-up chip.
WARNING
POWER TO THE SYSTEM SHOULD BE SWITCHED OFF BEFORE INSERTING OR REMOVING ANY
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.

COMMAND 03 ZERO
The Zero Command permits the calibration of the zero of most analog sensors. There are four sensors that can
be zeroed using Command 03. Each sensor is allocated a number that corresponds to the input to which it is
connected in the System.
These are as follows:
♦Piston side pressure transducer Input Tx.0
♦Rod side pressure transducer Input Tx.1
♦Boom extension sensor Analog input 2
♦Boom angle sensor Analog input 3
The swing sensor has its own routine and is calibrated using Command 05.

♦Lower the boom onto its lower end stops (boom hoist cylinder fully retracted).
♦Stop the hydraulic pump and reconnect electrical power to the System.
♦With the boom hoist cylinder fully retracted, ensure that no pressure remains in the boom hoist cylinders by
de-pressurizing the hydraulic tank and opening the hydraulic lines to the pressure transducers.
♦With the pressure transducers open to atmosphere, calibrate the zero of the piston and rod pressure
transducers using the sequence ON THE FOLLOWING PAGE.

The Extension Sensor is fitted with 130 ft. of shielded 2-wire cable. The cable cannot be shortened to
accommodate varying boom lengths. The following method of pre-tensioning is recommended.
♦Fully retract all the boom sections.
♦Pre-tension the reel using the following procedure:
♦With the boom fully retracted, remove the clamp on the reel cable and allow it to slowly rewind onto the
drum until there is no pre-tension. Continue to rewind the drum until the distance between the attachment
point and the end of the cable is approximately 12 ft. At this point, because of the clutch on the reel shaft
there will be no pre-tension. Now pull out the cable toward the attachment point and continue until the end
of the cable is 3 ft. beyond the anchor point. Secure the cable to the anchor point with at least 4 wraps,
ensuring that there is sufficient cable at the boom head to connect to the A.T.B. switch.
♦When the boom is fully retracted, manually turn the large gear on the MicroGuardpotentiometer fully
counterclockwise. Then, advance the gear clockwise three clicks (approximately ¼ turn on the gear).
♦Follow the sequence below to calibrate the zero of the sensor.

NOTE
THE INCLINOMETER OR MEASURING DEVICE USED TO CALIBRATE THE ANGLE OF THE MAIN BOOM
MUST HAVE AN ACCURACY OF +/- 0.25°. USE OF A LESS ACCURATE DEVICE MAY RESULT IN
CALIBRATION ERRORS.
USE GREAT CARE IN THE CALIBRATION OF THE BOOM ANGLE SENSOR. ALL SUBSEQUENT
CALCULATIONS ARE DEPENDENT ON THE ACCURACY OF THE CALIBRATION OF THIS SENSOR.
♦Raise the retracted boom to an angle between 60°and 65° and measure the angle using an inclinometer.
(E.G. 61.5°)
♦Calibrate the span of the Boom Angle Sensor:

EXTENSION SENSOR
EXTENSION SENSOREXTENSION SENSOR
EXTENSION SENSOR
THROUGHOUT THIS PROCEDURE DO NOT FULLY EXTEND THE BOOM IF THIS WOULD CAUSE A
TIPPING CONDITION. CARRY OUT CALIBRATION PROCEDURES ONLY WITHIN THE STABILITY LIMITS
OF THE CRANE.
(a) With the boom horizontal and fully retracted, measure the distance from the boom pivot to the hook
center line. Note the distance.
(b) Extend the boom as far as possible without tipping the machine and measure the distance from the
boom pivot to the hook center line. Note the distance.
(c) Calculate the boom extension from the formula Extended length minus Retracted
length equals Extension value.
e.g. IF THE EXTENDED BOOM LENGTH IS 72 FEET AND THE RETRACTED BOOM LENGTH IS
30.5 THEN THE EXTENSION VALUE IS 72 −30.5 = 41.5
(d) With the boom still fully extended, calibrate the SPAN of the EXTENSION by the use of the
following sequence:

THIS ROUTINE WILL ONLY BE EXECUTED ON MODELS THAT HAVE SWING POTENTIOMETERS. IF
EQUIPPED WITH SWING SWITCHES, CONTINUE WITH COMMAND 06 PRESSURE. Do not calibrate swing
if you do not have swing potentiometers
SCALE
SCALESCALE
SCALE
The swing command does not require the entry of measured data. All measurements of swing data are acquired
automatically by the system during the calibration of the swing sensor. However, it is essential that when the crane
upper is rotated during the scale procedure, it must be rotated slowly. This is especially important at the nodes
which occur at 180°and 360°. These points can be observed on the display during the procedure.
ZERO
ZEROZERO
ZERO
For all crane models, whether lattice or hydraulic and whether truck or all terrain, the datum for the zero of the
potentiometer is IN LINE OVER THE FRONT OF THE CARRIER.
DIRECTION
DIRECTIONDIRECTION
DIRECTION
Swing direction is likened to a compass. Swinging to the right will increase the readings and swinging to the left will
decrease the readings. If the swing potentiometer is mounted in such a way that its output is in the wrong
direction, this can be accounted for during this procedure by using the direction command to change the displayed
direction.
The 3 routines are carried out consecutively. ZERO and DIRECTION can be done in isolation of SCALE but any
time that SCALE is redone, it is followed by ZERO and DIRECTION.
Carry out the calibration of the swing potentiometer using the following sequence.
