Introduction
The RCI 514 System (hereinafter referred to as the “System”) is designed as an aid to crane
operation.
The operator must be knowledgeable in safety guidelines, crane capacity information, and the
crane manufacturer’s specifications.
This manual describes the operation of the system.
Please read, understand, and follow the contents and instructions contained within this manual.

OUTLINE OF OPERATION
SYSTEM COMPONENTS
 MicroGuard Display Unit
 MicroGuard Computer Unit
 Reeling Drum, with Length and Angle Sensors
 Anti Two-Block Switches
 Cables
 Installation/Operator Manuals.
The system is intended to aid the crane operator by monitoring the load and warning of an overload
or two-block condition. Crane functions are monitored by a variety of sensors.
The system compares the load suspended below the boom head to the crane capacity chart stored
within the computer’s memory.
At approach to overload, the system sends audible and visual warning signals. The system can be
configured to cause function kick-out by sending a signal to function disconnect solenoids.
DISPLAY
The operator is provided with a display of:
 Rated Load
 Actual Load
 Bar graph showing Percentage of Rated Load
 Radius of the Load
 Boom Angle
 Main Boom Length
 Working Area
 Crane Configuration
On screen communications provide the operator with visual warnings of conditions which may occur
during operation of the system.

OUTLINE OF OPERATION
BOOM ANGLE SENSOR
Boom angle is measured by a potentiometer/pendulum assembly. It provides a voltage proportional
to boom angle. The boom angle sensor is mounted inside the cable reeling drum assembly.
EXTENSION SENSOR
The extension sensor provides an increasing voltage proportional to the extension of the boom. A
cable attached to the boom head provides a low current electrical path for the A2B signal. The
extension sensor is mounted inside the cable reeling drum assembly.
PRESSURE SENSORS
There are two pressure sensors which measure pressure in the boom hoist cylinder. One sensor
for the rod-side pressure and one sensor for the piston-side pressure.
ANTI TWO BLOCK (A2B)
A switch monitors the approach of the hookblock or overhaul ball to the boom head. The switch is
held in the normal position until the hookblock or overhaul ball raises a weight that is mounted
around the hoist rope. When the weight is raised it operates the switch. The resultant signal is sent
to the computer via the reeling drum causing an A2B alarm and function kick-out to occur.
FUNCTION KICK-OUT
Electrically-operated hydraulic solenoids disconnect the control lever functions for boom hoist lower,
telescope out, and winch up when an overload or A2B alarm condition occurs.
OPERATOR PROGRAMMABLE ALARMS
These alarms, when properly set by the operator, define the operating range:
- Minimum and maximum angle
- Maximum height and/or maximum length.
These alarms are programmable for each job site and allow the operator to work in a defined area.
AREA ALARM
This alarm permits the operator to define the operating zone by only two set points. The use of this
method results clearly defines the operating zone.

will turn off, and the tire LED will illuminate.
5. The COUNTERWEIGHT group contains one LED. It is only active on machines that have
counterweight options.
6. The WINCH group contains two LEDs. They indicate the selection of FRONT or REAR
winch.
7. The STOWED JIB group contains one LED. This will illuminate when the jib is stowed on the
boom.
8. The MANUAL SECTION group contains one LED. It is active on machines that have pinned
extensions or active tip boom options.
9. The JIB group contains 6 LEDs. They indicate the length and offset of the jib in use.
10. The AUX HEAD group contains one LED that will illuminate when the AUX HEAD is fitted.
11. The POINT OF LIFT group contains three LEDs. A single LED will illuminate to show the
point of lift.

SYSTEM SETUP
CONFIGURATION DATA
The system has the capability of remembering all configuration data previously set.
After removing power to the system, and then re-powering, the settings remain intact until reset by
the operator.
After setting the configuration, the operation of the system depends only on selecting which winch is
in use. Changing the winch will automatically change the lifting point and the parts of line to the
values previously set for the selected winch.
NOTE: Always check the point of lift and parts of line following selection of the winch.
WARNING!
The displayed load and capacity are based upon the current selected point of lift.
Neither the RCI 514 system, nor the crane capacity chart, allows for lifting from more
than one hook at a time.

The Cancel Alarm button (Item1) is used to silence the audible alarm. Pressing this button once will
cancel an audible alarm which has occurred as a result of an:
 Overload
 A2B Alarm
 Operator Programmable Alarm
The audible alarm remains cancelled until the condition that caused the alarm has been removed.
For example, if the audible alarm sounded because of an overload condition it will remain cancelled
until the overload condition has been removed.
If another alarm condition that normally causes an alarm to sound, such as an A2B, occurs while
the audible alarm is cancelled or if the previous condition (overload) is removed and then reoccurs,
the new alarm condition will cause the audible alarm to sound again.
The Cancel Alarm button may also used to reset the function kick-out relay. It may be necessary to
override a function kick-out to clear the fault condition.
For example, if the boom hoist cylinder is fully extended the pressure will increase enough to create
a false overload and the FKO will not allow the operator to lower the boom. Using the bypass will
allow the operator to retract the boom hoist cylinder and clear the alarm condition.
When the machine is to be rigged it is often necessary to put the boom in a position which could
cause function kick-out. Using the bypass is necessary in this situation.
