OPERATOR'S INSTRUCTION MANUAL
This manual describes the function and operation ofthe MicroGuard Rated CapacityIndicator (RCI)
system for lattice boomcranes. The systemis intended to aid the crane operator in the efficient operation
ofhis crane bycontinuouslymonitoring the load and warn ofan approach to an overload or two-block
condition. The systemmonitors crane functions bymeans ofhigh accuracysensors and continuously
compares the load suspended belowthe boomhead with acopyofthe crane capacitychart which is
stored in the computer memory.If an overload is approached, the systemwarns bymeans of audible and
visual alarms and can be configured to cause function kick-out.
System Description
The MicroGuard 414 indicator provides the operator with a continuous displayof:
♦Rated Capacity
♦Actual Load
♦Percentage ofRated Capacity
♦Radius ofthe Load
♦Angle ofthe Main Boom
♦Working Area (ifapplicable)
♦Crane Configuration
and bymeans ofalternate displaypush-buttons it provides the operator with:
♦Length ofthe Main Boom.
♦Height ofthe BoomHead.
On screen messages provide the operator with visual indications ofthe various alarmswhich mayoccur
during normal operation ofthe system.These values are displayed on the leftand upper right display.
The lower right displaygives information about the currentlyselected crane configuration.

1 MAXIMUMRATED CAPACITY is a
digital displayofthe maximumpermitted
capacity.It is derived fromacopyofthe
crane's capacitychart which is stored in the
computer memoryand is the reference
capacityfor anylifting operation. It is
dependent on the configuration currently
selected which is shownin the lower right
displayand which determines the section of
the capacitychart to be used as the capacity
reference. Ifmaximumrated capacityis
limited byparts ofline then the displayed
MAXIMUM RATED CAPACITYis the rope
capacityand the message ROPE LIMITis
displayed in the information area.
2 The BAR-GRAPH is an analog
bar-graph in the upper displaywhich gives a
visual indication ofhowmuch ofthe machine
capacityis being used and the rate at which an
overload is being approached. This bar-graph
in conjunction with the 100% capacitymarker gives avisual indication ofwhen the overload point is
reached.
3 PERCENTAGE OF RATED CAPACITY is a part ofthe bar-graph display. A digital read-out within
the bar-graph displayexpresses Actual Load as apercentage ofMaximumRated Capacity.For
percentages ofless than 100% the displaywill be at the right side of the bar-graph. For percentages over
87% the displaywill move to the center ofthe bar-graph in order to make space for the leading edge ofthe
bar-graph.
4 The INFORMATION AREA provides the operator with avisual indication ofthe various alarms
which mayoccur during normal operation ofthe system.For example PRE-ALARM or OVERLOAD,
ROPE LIMIT.

screen. The self-test can be initiated at anytimeduring normal operation ofthe systembyuse ofthe
TESTpush-button.
TEST
One press (press and release) will cause the systemto execute aselftest routine during which all lamps,
audible alarmsand digital displayswill be functionallytested and all memoryareas checked for accuracy.
Iffaults in the systemare detected during atest, the information area in the upper displaywill showthe
word FAULT.Ifthe word FAULToccurs, press and continue to hold the TESTbutton. This will cause
the displayto change to the FAULT mode. In this mode information about the fault condition will be
displayed in the upper right displaybymeans ofan error code.
CANCEL ALARM
Used to cancel the audible alarmwhen the alarmhas occurred as aresult ofeither an Overload or an
Operator Settable alarm.The audible alarmmaybe canceled bypressing and releasing the CANCEL
ALARM button. The audible alarm remains canceled until the condition which caused the alarmhas been
removed. For example, ifthe audible alarmwas canceled because ofan overload condition it will remain
canceled until the overload condition is removed. However, ifadifferent alarm,e.g. operator settable
alarm,was to occur when the audible alarmwas still canceled for an earlier overload condition, the new
alarmcondition would cause the audible alarmto be re-started.
CANCEL ALARM is also used to reset the function kick-out relaywhen it is necessaryto by-pass function
kick-out which has occurred as aresult ofeither an overload or an A.T.B. alarm.The relayisre-set by
first canceling the audible alarm[as described above] and then pressing and holding the CANCEL ALARM
button for about 5seconds after which the function kick-out relaywill be set to normal operation.
However, should another different alarmcondition occur when the relayhad previouslybeen over-ridden
then the newlyoccurring alarmcondition would cause the motion cut to be re-started.
CANCEL ALARMis atemporary function. The audible alarm or function kick-out is automatically reset
when the condition which caused the alarm is no longer present.
WHEN FUNCTION KICK-OUT IS RESET BY MEANS OF THE CANCEL ALARM
BUTTON YOU ARE NO LONGER PROTECTED AGAINST THE CONDITION WHICH
CAUSED THE FUNCTION KICK-OUT.

OPERATOR SETTABLE ALARMS
Aadditional feature of the system is the provision of Operator Settable Alarms. These alarms, when
properly set by the operator, provide amethod of obstacle avoidance. This is achieved by means of
minimum and maximum angle and maximum height alarms. These alarms can be programmed for each
job site and set rapidly for the prevailing site conditions thereby aiding the operator in safe operation of the
crane.
Most alarmswill occur automaticallyas aresult of limitations imposed bythe capacitychart. The operator
has control over additional alarmswhich are set to define the working range ofthe machine for particular
site requirements and which will provide a measure ofobstacle avoidance.
Three alarms are available for operator use.
