After satisfactory installation of the complete system, ensure that it is correctly wired in accordance with the Wiring
Diagram, which is issued with the duty chip.
Before carrying out any crane operations ensure that the crane is on firm and level ground and that the outrigger
beams are fully extended and jacks are correctly extended to level the carrier.

The Display Unit provides the interface between the user and the calibration program. By pressing the various
keypads on the Display, the user communicates with the program and executes the calibration. Information and
data stored in the Display Unit are activated via on-screen prompts.
The six keypads are shown below with a description of their basic function.

Calibration routines are initiated by simultaneously pressing and holding the SELECT and TEST keys for
approximately 2 seconds. The display will then request entry of the Calibration Security Code.
To enter the Calibration Security Code, press the following keys IN THE SEQUENCE SHOWN BELOW.

Calibration procedures will only work with the
CAL switch in the computer set to the CAL

necessary to remove the cover from the
computer assembly. The switch is located near

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.

Upon completion of a calibration, it is necessary to carry out Command 01/0 SAVE. Refer to at the end of this
manual. 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-up memory.

The MicroGuardSystem 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.
