Introduction
Congratulations on choosing the new MicroGuard®586 Retrofit Rated Capacity Indicator System.
This manual describes the calibration process for the MicroGuard®Retrofit Rated Capacity Indicator
System (hereinafter referred to as “the system”) in an on-site environment and assumes that there
is no prior knowledge of the geometry of the crane other than data provided by the manufacturer.
This document also assists personnel in obtaining necessary measurements for calibration and in
maintaining a record of the measurements and test results for review and/or comparison when
changes are made. Recording measurements and test results during the calibration process will
ensure an organized and easy to follow calibration.
MG586 Calibration 2 W458199 Rev C 06/07
Required Tools
1/4” nut driver or T15 Torx driver•
Digital or bubble level calibrated and accurate to 0.1° at level•
100 foot measuring tape - fiber type graduated in tenths of feet•
.9 1 ft .1 .2
10 11 1 ft 1 2 3
1.0′
1′-0″ 1′-1″ 1′-23/4″
1.1′ 1.23′
Note: The computer calculates measurements in feet and tenths of a foot, so having the
correct measure will facilitate entering measurements.
Digital volt/Ohm Meter capable of measurements to three decimal places•
Number Conversion
If you are using a standard tape measure, the measurement must be converted into feet and tenths
of a foot. For example: a distance of 35’–6” would be entered into the system as 35.5 feet. Whole
inches can be easily converted by dividing by 12 (6/12=.5). Fractions of an inch are converted
by dividing the numerator by the denominator. For example: 1/4 inches would be entered as .25
(1/4=.25). Conversion of whole inches and fractions of an inch (for example 6-1/4”) are converted
by first converting the fraction to a decimal and then dividing by 12. In this case 6-1/4” is converted
to 6.25 and then divided by 12 which equals 0.520. Refer to the Fraction to Decimal Conversion
Chart on page C-5
When entering weights, the number must be converted by moving the decimal three places to the
left. For example: a weight of 1,400 pounds would be entered as 1.4, and a weight of 300 pounds
would be entered as .300.

Operator’s Display Console
Warning/Alarm Indicators
The red two-block lamp will illuminate when
a two-block condition occurs (see “Two-
Block Warning” on page 8).
The yellow pre-warning lamp will
illuminate at 90% of rated capacity (see
“Approaching Overload” on page 8).
When the load reaches or exceeds 100%
of rated capacity, the red overload warning
lamp will illuminate along with the yellow
pre-warning lamp (see “Maximum Capacity
and Overload” on page 8).
Display Windows
The current rated capacity for the crane in
the current configuration will be displayed
in the rated capacity window as well as
the percent of rated capacity shown as a
meter which progresses to the right as the
load increases (see “Normal Operation” on
page 7).
The setup codes are shown in the setup
code window, as well as the parts-of-line,
and the stowed jib option if available (see
“Configuration Selection” on page 6).
The information window shows crane
specific information regarding boom length,
boom angle, and working radius, along with the load on hook. In addition, information regarding any
warnings or alarms will be displayed in this window. If the system has any internal faults, it will display
“!WARNING! SYSTEM FAULT” in the information window. The specific fault messages can be viewed
by pressing the UP ARROW or DOWN ARROW key (see “System Fault Messages” on page A-1).

Push Buttons
The setUP key enables the operator to
configure the system to match the actual
setup of the crane. Codes are present for:
• stowed jib attachments; if no
stowed options are available, this
code will not appear
• crane configuration
• number of parts-of-line
The AlARm OveRRiDe (cANcel) key is
used to disable the audible warning and
to override the function kick-out for the
current alarm condition. It is also used to
exit a menu or routine.
The cONtRAst keys are used to adjust the
lightness or darkness of the display area.
The DisPlAy mODe/select keys are used to switch to different display formats showing various
combinations of boom angle, boom length, and radius. They can also be used as an UP ARROW or
DOWN ARROW key to scroll through menu selections.

System Operation
System Self-Test
When the system is turned on, it goes through a brief self-testing process.
All three alarm indicators will light up, all display
windows will appear black, and the audible
alarm will sound.
The information display will then show the
crane model and capacity chart number for the
system configured.
Following self-test, the system will go into the setup mode. The setup code window will display the
same setup code used when the system was last powered off. Check that the correct setup code
is displayed before operating the crane. Refer to “Configuration Selection” on page 6 for code setup
instructions.
MG586 Calibration 6 W458199 Rev C 06/07
Configuration Selection
Configuration selection is required upon system power up; however, it can also be entered anytime by
pressing the setUP key.
The first selection is fo the jib. Since no jibs are
stowed, the system defaults to the main boom.
Press the setUP/Ok key to continue.
The next selection is for the number of parts-
of-line.
To change the number of parts-of-line, press
the UP ARROW or DOWN ARROW key to
change the number and press the setUP/Ok
key to continue.
Note: Some configurations allow only single
part-of-line operation. In these cases, the whole
parts-of-line selection phase will be skipped and
the parts-of-line will be set to one (1).
Once the correct parts-of-line are entered, the
system will exit the configuration mode and return to the normal working screen.
