MicroGuard 534 Rated Capacity
Limiter
The following describes the function and operation of
the Microguard 534 Rated Capacity Limiter. The sys-
tem is intended to aid the operator in the efficient op-
eration of the crane by continually monitoring the load
and warning of an approach to an overload or unsafe
condition.
WARNING
Although the system will alert the operator of
an approaching overload or unsafe condition,
it remains the responsibility of the operator to
operate the crane safely at all times.
This system must never be substituted for the
good judgment of the crane operator using safe
operating procedures. The operator is solely
responsible for safe operation of the crane.
!!THIS SYSTEM IS AN OPERATOR’S AID −
NOT A SAFETY DEVICE!!
System Description
The system monitors crane functions by means of high
accuracy sensors and continuously compares the load
with a copy of the crane capacity chart which is stored
in the computer memory. If an overload is approached,
the system warns by means of audible and visual
alarms and is configured to cause function limitation.
The MicroGuard 534 Rated Capacity Limiter provides
the operator with a continuous display of:
Rated Capacity
Actual Load
Percentage of Rated Capacity
Radius of the Load
Angle of the Main Boom
Crane Configuration
Length of the Main Boom
An additional feature of the system is the provision of
operator settable alarms. These alarms, when proper-
ly set, provide a method of obstacle avoidance. This is
achieved by means of maximum boom angle, maxi-
mum load radius, maximum boom head height, left
and right swing, and defined area 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.

Display Unit
The following is a description of the control buttons, in-
dicators, and windows on the display unit. Use them
along with Figure 1−68.
1. Bar-Graph
The Bar-Graph is a series of twelve colored lights which
gives a visual indication of how much of the crane’s ca-
pacity is being used and the rate at which an overload
is being approached. Each green light represents 10%
of the crane’s rated capacity is being used. Yellow indi-
cates 90−99.9%, and the red lights indicate an over-
load.
Note: System may be equipped with an overhead
bar graph or an external light bar which operates
similar to the bar graph on the display. Refer to
Figure 1−69.
2. Pre-Alarm indicator
The Pre-Alarm (yellow) Indicator illuminates at a pre-
set value of 90% of Maximum Rated Capacity and pro-
vides a visual indication of an approach to an overload.

3. Overload Indicator
The Overload Indicator (red) illuminates at a pre-set
value of 100% of Maximum Rated Capacity and pro-
vides a visual indication of Maximum Allowed Load. It
will also illuminate whenever a wire rope limit is exceed-
ed. Function limiters will occur simultaneously for an
Overload, Wire Rope Limit, or a Two Block condition
but function limiters will not occur when exceeding an
operator settable alarm. An audible alarm will sound
and a message will appear in the warning message
area for all 4 conditions.
4. Maximum Rated Capacity Display
The Maximum Rated Capacity is a digital display of the
maximum permitted capacity. It is derived from a copy
of the crane’s capacity chart which is stored in the com-
puter memory and is the reference capacity for any lift-
ing operation. It is dependent on the configuration cur-
rently selected, which is shown in the crane setup
screen, and which determines the section of the ca-
pacity chart to be used as the rated capacity reference.
5. Actual Load Display
The Actual Load Display is a digital display which
shows total load suspended below the boom or fly
head. It includes the load, any slings, pins, or tackle
used to secure the load and the hook block or ball.
6. Parts-of-Line Display
Parts-of-Line displays the parts of line currently se-
lected for the winch in use.
7. Configuration Selection Buttons
These buttons are used during the crane configuration
selection routine. Refer to Configuration Selection"
found later in this Section of the Operator’s Manual.
8. Cancel Alarm Button
This button is used to silence the audible alarm when
the alarm has occurred as a result of either an Over-
load, Wire Rope Limit, a Two Block, or an Operator Set-
table alarm. It is also used to reset the function limit
relay when it is necessary to by-pass function limit
which has occurred as a result of either an Overload,
Wire Rope Limit, or a Two Block alarm.
9. Operator Alarms Button
This button is used to start the operator settable alarms
routines. Refer to Operator Settable Alarms" found
later in this section of the Operator’s Manual.
10. Crane Setup Button
This button is used to start the configuration selection
routine. Refer to Configuration Selection" found later
in this Section of the Operator’s Manual.
11. Display/Select Button
This button is used to access the Calibration And Diag-
nostic Screen. Refer to System Fault Codes" and
Calibration" found later in this Section of the Opera-
tor’s Manual.
12. Warning Message Area
The Warning Message Area displays text messages of
various alarms which may occur during normal opera-
tion of the system. When an alarm occurs, the rectan-
gular area fills in red.
13.Boom Length Display
The Boom Length Display gives a continuous indica-
tion of the boom length in feet (m). It is the distance
from the centerline of the boom foot pin to the center
line of the boom head machinery.
14. Brightness Buttons
These buttons are used to adjust the display bright-
ness.
15. Load Radius Display
The Load Radius Display gives a continuous indication
of the radius of the load in feet (m). It is the horizontal
distance from the centerline of rotation to the centerline
of the hook.
16. Boom Angle Display
The Boom Angle Display gives a continuous indication
of the angle of the main boom relative to horizontal.
17. Erected Attachment Display
The Erected Attachment Display gives a continuous
display of the erected attachment with the top number
indicating the actual fly length and the bottom number
indicating the offset angle if applicable.

System Operation
The following is a list of procedures which are used to
operate the multiple features of the Rated Capacity
Limiter. Use these procedures in conjunction with the
previous display unit control descriptions.
System Self-Test
At start-up the system automatically performs a self test
after which all lamps, audible alarms, and digital dis-
plays will be functionally tested and all memory areas
checked for accuracy. If faults in the system are de-
tected during a test, the warning message area will
show the words SYSTEM FAULT. If the words SYSTEM
FAULT occur, press the Display/Select button to dis-
play the Calibration And Diagnostic screen. Through
the Calibration And Diagnostic screen, information can
be accessed about the fault condition by means of an
error code. Contact your local distributor for details of
the fault codes.
Note: If the batteries have been disconnected inter-
rupting power to the computer, the start-up time for
on-board computer systems will be longer than
normal.
System Bypass
In emergency situations, the Rated Capacity Limiter
computer can be bypassed. The computer is located
on the back of the operator’s cab. Refer to
Figure 1−70. There is a RCL Status keyswitch adja-
cent to the computer to bypass the system. Move the
key to the Bypass" position to bypass the system. For
emergency use while the system is bypassed, refer to
System Inoperative or Malfunctioning" that follows.
WARNING
The Microguard 534 is not operational when
the computer is bypassed. Bypass the
system in emergency situations only.
System Inoperative Or Malfunctioning
When operational aids are inoperative or malfunction-
ing, the following recommendations for continued use
of the crane should be followed or the crane should be
shutdown.
1. Steps shall be taken to schedule repairs and recal-
ibration immediately. The operational aids shall be
put back into service as soon as replacement
parts, if required, are available and the repairs and
recalibration can be carried out. Every reasonable
effort must be made to expedite the repairs and re-
calibration.

2. When the rated capacity limiter is inoperative or
malfunctioning, the designated person responsi-
ble for supervising the lifting operations shall es-
tablish procedures for determining load weights
and shall ascertain that the weight of the load does
not exceed the crane ratings at the radius where
the load is to be handled.
3. When a boom angle or radius indicator is inopera-
tive or malfunctioning, the radius or boom angle
shall be determined by measurement.
4. When the anti-two block warning device is inopera-
tive or malfunctioning, the designated person re-
sponsible for supervising the lifting operations
shall establish procedures, such as assigning an
additional signal person, to furnish equivalent
protection. This does not apply when lifting per-
sonnel in load line supported baskets. Personnel
shall not be lifted in load line supported baskets
when the anti-two block devices are not function-
ing properly.
5. When a boom length indicator is inoperative or
malfunctioning, the designated person responsi-
ble for supervising the lifting operations shall es-
tablish the boom length at which the lift will be
made by actual measurement or markings on the
boom.
6. When a level indicator is inoperative or malfunc-
tioning, other means shall be used to level the
crane.
7. In situations where inconsistency exists, verified
weights, measured radii, boom lengths, and au-
thorized crane capacities must always take prece-
dence over indicator readings.
