ITRODUCTIOITRODUCTIO 551.11.1 OverviewOverviewThe GS820 system includes the cabin mountedGS820 radio display and compatible cranemounted sensors. The GS820 creates a two-wayradio network with the sensors to bring required liftdata to the operator. Hoist load, boom and jibangles, boom length, wind speed and pending two-block can be detected and then indicated to theoperator in real time. Working load radius can becalculated and compared to a rated capacity chart(if programmed). Furthermore the GS820 can beprogrammed to generate warnings, alarms andlockout commands, all triggered by adjustablethresholds and limits. All these events can berecorded by the data logger with a time and datestamp. The exact operational function of theGS820 system depends on the sensorconfiguration used and the rated capacity chartsprogrammed (where applicable). The GS820includes a USB port to facilitate software and chartupdates and data logger downloads using a USBmass storage device (USB key).1.21.2 Start-UpStart-UpThe GS820 must be correctly programmed for thesystem sensors installed. Once a reliable radiocommunication network is established, the displaylights will remain lit without flashing. If a sensor ismissing or has a problem, a message will bedisplayed on the LCD (liquid crystal display).This process may take up to one minute. The delayis created by the battery management function.Press Bypass/Exit to temporarily bypass cranefunction lockout caused by a missing sensor. Ifrigging requires a crane configuration outside of thelimits defined by the rated capacity chart selected,out of chart alarms can be avoided by placing thethe display in "rig mode". If the rig mode is enabledin the display, press Bypass/Exit for 10 secondsto activate it. If the rig mode is not available, contactyour LSI LSI representative or LSILSI technical supportrepresentative.1.1.

ISTALLATIOISTALLATIO 772.1b Antenna PositionFor optimal performance the antenna should bepositioned on its side such that it is parallel tothe sensor antennas (but not pointing directly to ordirectly away from them).1. Adjust the antenna position with the articulating base.2. The antenna should have 5 inches of clearspace all around it.3. The antenna should have an unobstructed line ofsight to all sensor antennas at all boom angles.2.1c Power Supply and LockoutConnection1. Connect the black wire (ground) to the negativeterminal of the battery or the panel connection;alternatively bolt the black wire to the body ofthe machine with a 1/4 inch or 5/16 inch bolt.The ground connection must be strong enoughto sustain 3 amperes. 2. Connect the red wire to a fused accessorysource, rated at least 3 amperes, that supplies+12 or +24 volts when the machine is in use.The GS820 will automatically detect the voltagelevel and adjust itself. 3. Lockout number 1 (if required): connect thewhite wire to a Bosch relay coil terminal.Connect the other coil terminal of the relay tothe ground. When operating properly the whitewire will energize at the battery positive level.Current over 1 ampere on the white wiretriggers an auto re-settable fuse. Current flowwill resume several seconds after the shortcircuit is eliminated.4. Lockout number 2, 3 and 4 (if required): thesewires function in the same way as the white wiredescribed in step 3 above. Each lockout wirecan be triggered by a different set of alarmconditions; see the Lockout Settings subsection of this manual.5. Connect the yellow cable to the GS820. Theconnector is waterproof and well rated forexternal environments. Simply connect thecable to the display and gently tighten the nut.Do not put a kink in the yellow cable whereit enters the connector; any bend in the cableat the base of the connector must not be sosevere as to break the internal connectionswhere the cable meets the connector.

1010 The GS820 SystemThe GS820 System2.22.2 Load CellLoad Cell1. Install load cell bushings as supplied by LSILSI.Assembly of the load cell and adapter platesmust be configured to the pin size required bythe specific dead end or hook to which it is to beattached. In all cases, the bushings supplied byLSILSI must be used where possible to adapt theholes in the load cell to the pins. Bushings mustbe secured with the two allen screws provided,one on each side of the load cell.2. As required, place a washer between adapterplate and pin head or nut on each end of the pinthat links the adapter plates to the load cell.Additional washers should be added equally toeach end of the pin as required to inhibitexcessive lateral movement of load cell(maximum 1/8” total movement) and adapterplates along the pin. 3. If the dead end or hook to be connected to theadapter plates requires a larger opening,washers may be placed between the load celland the adapter plates equally on both sides ofthe load cell. 4. In all cases the washers must be placedsymmetrically such that the load cell is centeredon the pins to avoid uneven loading.5. Secure the pins with the nuts and cotter pinsprovided. 6. A qualified (lift supervisor or crane inspector)person must verify every lift assembly beforefirst use and periodically thereafter (one totwelve months), including before any new,difficult or otherwise different lift.Crane deadendPlate kit forloadlinkLoadcellWedge socketto loaded cableC/CFigure: Typical load cell and adapter plate assembly installed.IMPORTANT!The load cell antenna shouldnot be in contact with metal.IMPORTANT!For optimal performance andsignal reception, the GS820 load cell antennashould have a clear line of sight to theGS820 display.IMPORTANT!The load cell antenna shouldpoint to the left or to the right of the boom; itshould not point directly to, or away from, theGS820 display.WARNING!Capacity and safety factor forload cells and adapter plate assemblies arecalculated for load along the intended axis ofload (vertical with the assembly hangingfree); side loading may cause load cell andadapter plate assembly to fail, causing load todrop. Lifts must be rigged such that the loadcell and adapter plate assembly hang free andnot be subjected to side loading.!!!!CAUTION!The load cell must be centeredon the pins to avoid uneven loading on theplate kit assembly.!!
ISTALLATIOISTALLATIO 11112.32.3 Angle SensorsAngle Sensors2.3a Mounting ProcedureThe GS010 series angle sensors can be turned onby starting up the GS820 display to which they areprogrammed. The angle sensor can then assist inlevelling itself with the red and green LED.1. Determine the angle sensor position.a. The GS010-01 boom angle sensor canbe mounted on either side of the boom.b. The GS010-02 360° angle sensor mustbe mounted on the port side of the jib.c. The angle sensor must be level with theboom or jib centerline.d. The top / bottom axis of the angle sensormust be within 15 degrees of verticale. The angle sensor should have a clear lineof sight to the cabin mounted display.f. The angle sensor antenna should notcontact a metal object.2. Install the welding pads; keep the angle sensorat least three feet from the weld site and anyconnecting metal objects while welding.3. Mount the angle sensor to the weld pads withthe screws and washers provided.4. Verify angle indication on the GS820 LCD.5. If the angle displayed by a GS010-01 boomangle sensor is a high negative value, then tiltthe angle sensor up over 45 degrees, and thentilt back down to horizontal. The GS010-01boom angle sensor will automatically detect onwhich side of the boom it is installed and correctangle indication accordingly.2.3b Angle Calibration Procedure№ 1: Mechanical Set-Up1. Level the boom such that it is perfectlyhorizontal; use a high quality bubble or digitalangle sensor. If the GS820 display indicates 0.0degrees then angle calibration is complete; ifnot then continue to step 2.CabinBoomAngle SensorBoomCLBoomAngle SensorCabinBoomAngle SensorCabinWedgeFigure: Angle sensor level with the boom (typical installation) -Side ViewFigure: Angle sensor top/bottom axis within 15° of vertical(typical installation) - Front ViewFigure: Wedge used to mount the angle sensor with itstop/bottom axis within 15° of vertical (typicalinstallation) - Front ViewFigure: Typical operation page with boom angle indicationIMPORTANT!Keep the angle sensor awayfrom the boom and any connecting metalstructures when welding the metal lugs to theboom. Proximity to welding may causepermanent damage to the angle sensor andprevent accurate angle indication.!!WARNING!The angle reading may beaffected by vibration and may fluctuate; theangle sensor should not be installed in closeproximity to a high RPM electric motor or othersource of high frequency vibration.!!WARNING!Failure to ensure the boom islevelled will result in false reading of thecrane’s radius hence the risk of structuralfailure of the crane or crane tipping over.!!
1212 The GS820 SystemThe GS820 System2. For GS011 angle/length sensors only: Carefullyremove the cover of the GS101 cable reel.3. Loosen the mounting screw in the slotted holeof the angle sensor mounting plate.4. Pivot the angle sensor slightly until angleindication is correct. Repeat the angle validation(step 1) as required.2.3c Angle Calibration Procedure№ 2: Correct with the GS820Calibrate angle indication by adjusting the trim (offset)value in the GS820 display; the GS820 will thencommunicate the updated trim value to the sensor.1. Position the boom at a precisely known angle.2. Go to menu 4) and select 4B) SENSOR CALIBRATION.3. Enter the user password and press Enter.4. Select 4B2) MANUAL PARAMETER ADJUSTMENT.5. Use Up and Down to select the angle sensorto be calibrated and press Enter.6. Select 2) TRIM:and press Enter to modify.7. Use Up and Down to modify the trim value.Example: If angle indicated is 0.3° over the actualangle, adjust the trim value to -0.3.Example: If angle indicated is 0.9° below the actualangle, adjust the trim value to 0.9.8. Press Enter to save changes.9. Press Exit to return to the operation display.10.Verify accurate angle indication at both veryhigh and very low angles.2.42.4 Anti-Two-Block SwitchAnti-Two-Block SwitchVerify the anti-two-block switch is programmed tothe GS820 display. Switches shipped with displaysare pre-programmed in the factory. Test: if theswitch has been programmed to the display thenthe display will go in to two-block alarm when thewire rope of the switch is released. Press Bypassto silence the alarm until the next two-block eventor simulation. If the switch has not beenprogrammed to the display, this should be donebefore proceeding with installation. See the sectionHow to Add a Sensor to the GS820.2.4a GS050 Installation1. Position the sensor mounting bracket. Toensure that the sensor can pivot securely on themounting bracket throughout the full range ofboom angle, the mounting bracket must bepositioned at a 30° from horizontal with theboom parallel to the ground and such that thelocking pin of the mounting bracket points up.Bolt or weld securely.Figure: Angle Calibration Procedure № 2Note: When the angle sensor is moved very slowly,it may take several seconds to see an update at theGS820 display. Instead move the sensor up a coupleof degrees, and then bring it back down to where itshould be.

The slack rope limit isusually adjusted to less than the weight of allrigging below the load sensors. The defaultslack rope minimum limit for is 1000 (pounds orkilograms depending on load display units).Program the slack rope sensor.1. Go to menu 4) INSTALLATION and select 4A1)SENSOR LIST.2. Enter the user password and press Enter.3. Use Up and Down to advance to the nextavailable sensor position, usually following thefour load sensors, the sum load sensor and theimbalance sensor. Press Enter to modify.4. Use Up and Down to select the sensor type“Slack rope sensor”. Only one slack ropesensor is required to calculate slack rope for allfour load sensors.5. The ID can be left at 0, press Enter.6. Press Exit to return to the operation display.7. Adjust the slack rope minimum limit in menu 6)SYSTEM LIMITS.
2828 The GS820 SystemThe GS820 System2.122.12 List and Trim AngleList and Trim AngleSensorSensorThe GS010-03 is a two axis angle sensor designedto detect both list and trim angle. Minimum andmaximum limits for list and trim angle areadjustable in the display. The display will generatean alarm if the limits are exceeded and can beprogrammed to generate lockout. Furthermore listand trim angle can be used to control ratedcapacity chart selection where required (example:barge cranes).2.12a Programming the GS820 forList and Trim IndicationFor list indication, add the GS010-03 ID number tothe sensor list (menu 4A)) and select the sensor type“List sensor”.For trim indication, add the GS010-03 ID number tothe sensor list (menu 4A)) and select the sensor type“Trim sensor”.The maximum and minimum angles for list and trimindication can be adjusted in the limit menu. Thedefault limits are 10.0° maximum and -10.0°minimum.2.12b Mounting Instructions1. Determine the angle sensor position.a. The mounting surface should be flat andknown to be level (0°) in both the list andtrim axes.b. The angle sensor should have a clear lineof sight to the cabin mounted display.c. The angle sensor should be installedhorizontally, with the antenna pointing up.d. The list and trim axes are indicated on theangle sensor, follow these indications toorient the sensor correctly for accurate listand trim indication.e. The angle sensor antenna should notcontact a metal object.2. Install the welding pads; keep the angle sensorwell removed from the weld site and anyconnecting metal objects while welding.3. Mount the angle sensor to the weld pads withthe screws and washers provided.4. Verify list and trim angle indication in theoperation display.Figure: Trim and list angle indicationList (roll)Trim (pitch)Figure: List and Trim axesIMPORTANT! Remove the angle sensorfrom any connecting metal structures orsurfaces when welding the metal lugs to themounting surface. Proximity to welding maycause permanent damage to the angle sensorand prevent accurate angle indication.!!
