INTRODUCTION 1.1 Overview 1.2 Start-Up The GS820 system includes the cabin mounted GS820 radio display and compatible crane mounted sensors. The GS820 creates a two-way radio network with the sensors to bring required lift data to the operator. Hoist load, boom and jib angles, boom length, wind speed and pending twoblock can be detected and then indicated to the operator in real time. Working load radius can be calculated and compared to a rated capacity chart (if programmed). Furthermore the GS820 can be programmed to generate warnings, alarms and lockout commands, all triggered by adjustable thresholds and limits. All these events can be recorded by the data logger with a time and date stamp. The exact operational function of the GS820 system depends on the sensor configuration used and the rated capacity charts programmed (where applicable). The GS820 includes a USB port to facilitate software and chart updates and data logger downloads using a USB mass storage device (USB key). The GS820 must be correctly programmed for the system sensors installed. Once a reliable radio communication network is established, the display lights will remain lit without flashing. If a sensor is missing or has a problem, a message will be displayed on the LCD (liquid crystal display). This process may take up to one minute. The delay is created by the battery management function. Press Bypass/Exit to temporarily bypass crane function lockout caused by a missing sensor. If rigging requires a crane configuration outside of the limits defined by the rated capacity chart selected, out of chart alarms can be avoided by placing the the display in "rig mode". If the rig mode is enabled in the display, press Bypass/Exit for 10 seconds to activate it. If the rig mode is not available, contact your LSI representative or LSI technical support representative. ! WARNING! The GS820 system is designed as an operator aid and is in no way a substitute for safe operating practice.

By default the lockout wires carry crane power supply voltage as long as the display is in safe condition. When lockout is triggered voltage is cut on the lockout wires linked to the lockout condition. WARNING! Inverting lockout relays will allow crane operation in the event the GS820 display fails. Operating a crane without a functioning anti-two-block system and load and angle indication is dangerous and may be against the law. Exceptionally the lockout relay can be inverted so that lockout wires carry no voltage in safe condition and carry crane power supply voltage when in a triggered lockout condition. In this case if the display fails, crane functions will not lockout. 2. Use Up and Down to switch between “YES” and ”NO” and press Enter to confirm any change. 3.

Capacity and safety factor for load cells and adapter plate assemblies are calculated for load along the intended axis of load (vertical with the assembly hanging free); side loading may cause load cell and adapter plate assembly to fail, causing load to drop. Lifts must be rigged such that the load cell and adapter plate assembly hang free and not be subjected to side loading. 4. In all cases the washers must be placed symmetrically such that the load cell is centered on the pins to avoid uneven loading. 5. Secure the pins with the nuts and cotter pins provided. 6. A qualified (lift supervisor or crane inspector) person must verify every lift assembly before first use and periodically thereafter (one to twelve months), including before any new, difficult or otherwise different lift. ! CAUTION! The load cell must be centered on the pins to avoid uneven loading on the plate kit assembly. ! IMPORTANT! The load cell antenna should not be in contact with metal. Crane dead end IMPORTANT! For optimal performance and signal reception, the GS820 load cell antenna should have a clear line of sight to the GS820 display. Plate kit for loadlink IMPORTANT! The load cell antenna should point to the left or to the right of the boom; it should not point directly to, or away from, the GS820 display. 1. Install load cell bushings as supplied by LSI . Assembly of the load cell and adapter plates must be configured to the pin size required by the specific dead end or hook to which it is to be attached. In all cases, the bushings supplied by LSI must be used where possible to adapt the holes in the load cell to the pins. Bushings must be secured with the two allen screws provided, one on each side of the load cell. 2. As required, place a washer between adapter plate and pin head or nut on each end of the pin that links the adapter plates to the load cell. Additional washers should be added equally to each end of the pin as required to inhibit excessive lateral movement of load cell (maximum 1/8” total movement) and adapter plates along the pin. Loadcell C/C Wedge socket to loaded cable Figure: Typical load cell and adapter plate assembly installed. 3. If the dead end or hook to be connected to the adapter plates requires a larger opening, washers may be placed between the load cell and the adapter plates equally on both sides of the load cell. 10 The GS820 System e. The angle sensor should have a clear line of sight to the cabin mounted display. f. The angle sensor antenna should not contact a metal object. 2.3 Angle Sensors ! IMPORTANT! Keep the angle sensor away from the boom and any connecting metal structures when welding the metal lugs to the boom. Proximity to welding may cause permanent damage to the angle sensor and prevent accurate angle indication. 2.3a Mounting Procedure Cabin WARNING! The angle reading may be affected by vibration and may fluctuate; the angle sensor should not be installed in close proximity to a high RPM electric motor or other source of high frequency vibration. 2. Install the welding pads; keep the angle sensor at least three feet from the weld site and any connecting metal objects while welding. Boom CL 3. Mount the angle sensor to the weld pads with the screws and washers provided. Boom Angle Sensor 4. Verify angle indication on the GS820 LCD. Figure: Angle sensor level with the boom (typical installation) Side View Angle Sensor Cabin Boom Figure: Angle sensor top/bottom axis within 15° of vertical (typical installation) - Front View Angle Sensor Cabin Figure: Typical operation page with boom angle indication Boom Wedge Figure: Wedge used to mount the angle sensor with its top/bottom axis within 15° of vertical (typical installation) - Front View The GS010 series angle sensors can be turned on by starting up the GS820 display to which they are programmed. The angle sensor can then assist in levelling itself with the red and green LED. 1. Determine the angle sensor position. a. The GS010-01 boom angle sensor can be mounted on either side of the boom. b. The GS010-02 360° angle sensor must be mounted on the port side of the jib. c. The angle sensor must be level with the boom or jib centerline. d. The top / bottom axis of the angle sensor must be within 15 degrees of vertical ISTALLATIO 5. If the angle displayed by a GS010-01 boom angle sensor is a high negative value, then tilt the angle sensor up over 45 degrees, and then tilt back down to horizontal. The GS010-01 boom angle sensor will automatically detect on which side of the boom it is installed and correct angle indication accordingly. 2.3b Angle Calibration Procedure № 1: Mechanical Set-Up 1. Level the boom such that it is perfectly horizontal; use a high quality bubble or digital angle sensor. If the GS820 display indicates 0.0 degrees then angle calibration is complete; if not then continue to step 2. ! WARNING! Failure to ensure the boom is levelled will result in false reading of the crane’s radius hence the risk of structural failure of the crane or crane tipping over. 11 2. For GS011 angle/length sensors only: Carefully remove the cover of the GS101 cable reel. 3. Loosen the mounting screw in the slotted hole of the angle sensor mounting plate. 2.4 Anti-Two-Block Switch ! WARNING! Keep the anti-two-block switch away from the boom and any connecting metal structures when welding mounting brackets to the boom. Proximity to welding may cause permanent damage to the antitwo-block switch and render the anti-twoblock system unsafe. 4. Pivot the angle sensor slightly until angle indication is correct. Repeat the angle validation (step 1) as required. Note: When the angle sensor is moved very slowly, it may take several seconds to see an update at the GS820 display. Instead move the sensor up a couple of degrees, and then bring it back down to where it should be. The small light on the angle sensor flashes when it transmits a new value to the display. 2.3c Angle Calibration Procedure № 2: Correct with the GS820 Calibrate angle indication by adjusting the trim (offset) value in the GS820 display; the GS820 will then communicate the updated trim value to the sensor. 1. 2. 3. 4. 5. Position the boom at a precisely known angle. Go to menu 4) and select 4B) SENSOR CALIBRATION. Enter the user password and press Enter. Select 4B2) MANUAL PARAMETER ADJUSTMENT. Use Up and Down to select the angle sensor to be calibrated and press Enter. 6. Select 2) TRIM: and press Enter to modify. IMPORTANT! To ensure reliable radio communication between the anti-two-block switch and the GS820 display the following conditions must be respected: • The antenna of the anti-two-block switch should not be in contact with metal. • The anti-two-block switch antenna should point to the left or to the right of the boom; it should not point directly to, or away from, the GS820 display. • The anti-two-block switch antenna should have a clear line of sight to the GS820 display; in most cases this means mounting the sensor on the same side of the boom as the operator's cab. Verify the anti-two-block switch is programmed to the GS820 display. Switches shipped with displays are pre-programmed in the factory. Test: if the switch has been programmed to the display then the display will go in to two-block alarm when the wire rope of the switch is released. Press Bypass to silence the alarm until the next two-block event or simulation. If the switch has not been programmed to the display, this should be done before proceeding with installation. See the section How to Add a Sensor to the GS820. 2.4a GS050 Installation Figure: Angle Calibration Procedure № 2 7. Use Up and Down to modify the trim value. Example: If angle indicated is 0.3° over the actual angle, adjust the trim value to -0.3. Example: If angle indicated is 0.9° below the actual angle, adjust the trim value to 0.9. 1. Position the sensor mounting bracket. To ensure that the sensor can pivot securely on the mounting bracket throughout the full range of boom angle, the mounting bracket must be positioned at a 30° from horizontal with the boom parallel to the ground and such that the locking pin of the mounting bracket points up.

Arc welding may damage LSI sensors, causing immediate failure or greatly reducing functional life. Arc welding on or near LSI equipment will void warranty. Keep LSI equipment well clear of any arc welding. The GS101 includes the LS101 cable reel and the GS011 angle/length sensor. The GS011 is concealed under the cover of the LS101, though the antenna is visible. Following cable reel installation and boom length indication calibration, boom angle indication will have to be verified and possibly calibrated. Refer to Angle Calibration Procedure № 1: Mechanical Set-Up and Angle Calibration Procedure № 2: Correct with the GS820, sections of this manual. 2.5b Mounting the Cable Reel 1. Determine placement. Find a clear mounting position on the left side of the first (main) section of the boom. The mounting position should be close to the base of the boom; at least ten feet (three metres) from the tip of the first section and where the cable reel won’t obstruct free boom movement at all boom angles and slew positions. Furthermore, the reel must be placed such that the cable has a clear straight line to the end of the last section at all boom lengths. Welding pad holes tapped 3/8-16 Boom tip Welding pads GS011 angle/length sensor antenna Welding pads level and in line with the boom at 0 degrees from horizontal Boom base Welding pads holes 16 1/8 in. apart, centre-to-centre Welding pad holes 2 1/4 in. apart, centre-to-centre Figure: Cable reel mounting position LS011 length sensor cable reel Figure: GS101 angle & length sensor 2.5a Maximum Boom Extension Confirm the maximum extension of the LS101 cable reel is compatible with the maximum boom length. Step 1. Note the cable reel maximum extension: 100 feet (30.5 metres) unless specified otherwise. T = ____________________ Step 2. Note the retracted boom length. 2. Mount the welding tabs. They must be placed parallel to each other, with 16 1/8” inches between the holes’ centres. Install the tabs such that they create a level mounting position in line with the boom at 0 degrees. Note: When factory installed the GS011 angle/length sensor transmitter is integrated to the LS101 cable reel with the angle sensor zeroed. If the cable reel is installed perfectly level on the boom at 0 degrees, the angle sensor of the GS011 will also be zeroed. Minor adjustments to the angle sensor (within plus or minus two degrees) are possible after cable reel installation. A = ____________________ Step 3. Note the maximum extended boom length, not including jib. B = ____________________ Step 4. Calculate maximum boom extension. C = B – A =____________________ Step 5. Compare cable reel maximum extension (T) to maximum boom extension (C). D = T – C =____________________ Maximum cable reel extension must be greater than maximum boom extension. ISTALLATIO 3. Attach the reel to the welding tabs with the bolts provided. 4. Install the first cable guide (PA111) about 10 feet (3 metres) from the cable reel. Correct alignment of the first guide is critical to ensure orderly winding of the cable on the reel. Install the other guides at the end of each of the intermediate sections and the anchor (PA113) at the end of the last section. All guides must be aligned so as to permit unobstructed movement of the cable. 5. Pull out at least 5 feet (1-1/2 metres) of cable, but not more than half the excess extension of measurement D. Feed through the cable guides 15 and attach to the cable anchor on the tip of the last boom section. If additional cable length is required to reach the cable anchor point remove winds from the reel without putting additional tension on the cable reel spring. There should be minimal tension on the cable reel spring when the boom is fully retracted. 6. Verify the boom length indicated on the GS820 LCD. Boom length indicated should equal the actual total boom length. The actual boom length is the distance from the boom base pin to the head sheave centre as measured along the boom centreline. Depending on the exact placement of the cable reel and the cable anchor the displayed Procedure № 1: Mechanical Set-Up 1. Fully retract the boom 2. Adjust the loose wire rope at the boom tip so that the displayed boom length matches the actual boom length. 3. Fully extend the boom 4. Verify the boom length indicated at full boom extension matches the actual fully extended boom length. If not then follow Boom Length Calibration Procedure № 2: Correct with the GS820. 2.5d Boom Length Calibration Procedure № 2: Correct with the GS820 If the displayed boom length does not match the actual length of the boom retracted or extended and if it is not possible to easily correct by following 2.6c Boom Length Calibration Procedure № 1, then follow this procedure. This procedure is completed in the operators cab, it requires fully retracting, and then fully extending the boom, as prompted by the on screen instructions. 1.

Test № 1: measure the actual radius and compare to the radius indicated. Repeat with the boom at minimum angle, at 45 degrees, and at maximum angle; repeat at minimum and maximum boom length**. If radius indication is not accurate then go to step 4. 4. Measure the basic radius parameters on the crane. 5. Program the basic radius parameters in the RADIUS SETTINGS menu. Figure: The boom length calibration wizard, confirm maximum boom length. actual fully extended boom length, and then 6. Test № 2: measure the actual radius and compare to the radius indicated. Repeat with the boom at minimum angle, at 45 degrees, and at maximum boom angle; repeat at minimum and maximum boom length**. If radius indication is not accurate then go to the next step. Note: If the difference between the displayed radius and actual radius remains constant at all boom lengths and angles, then correct by adjusting the slew offset. For example: if the radius displayed is always 2.3 feet longer than the actual radius, then subtract 2.3 from the slew offset. 7. If the crane is rigged with the main boom only, then go directly to step 11. Figure: The boom length calibration wizard, Trim and Scale values. press Enter to confirm. 8. Note the new trim and scale values. 9. Press Enter to send the new calibration to the length sensor. 10. Press Exit to return to the operation display. 8. If the crane is rigged with a rooster, jib, or other extension then the advanced radius parameters must be measured on the crane and then programmed in the RADIUS SETTINGS menu of the display. 9. Test № 3: measure the actual radius and compare to the radius indicated. Repeat with the boom at minimum angle, at 45 degrees, and at maximum boom angle; repeat at minimum and maximum boom length**. If radius indication is not accurate then go to the next step. * When the hoist is rigged off of a luffing jib only ** Telescopic boom cranes only *** Systems with rated capacity charts programmed in the GS820 only ISTALLATIO 17 10. Test for boom deflection (telescopic crane only): is the radius indicated equal to the actual radius with the boom at 0 degrees and at 90 degrees but smaller than the actual radius with the boom at 45 degrees? If yes then adjust the boom deflection value to compensate: a. Raise the boom to 45 degrees with a known load. b. Compare the indicated radius with the actual radius. Change the boom deflection value and again compare the radius displayed with the actual radius. Repeat until the radius displayed equals the actual radius. Note: with the boom at 45° and the maximum load on the hoist, the boom deflection value should equal the difference between the actual and the displayed radius. With the boom at 45° and half the maximum load on the hoist, the boom deflection value should equal twice the difference between the actual and the displayed radius. 11. Test № 4: measure the actual radius and compare to the radius indicated. Repeat with the boom at minimum angle, at 45 degrees, and at maximum boom angle; repeat at minimum and maximum boom length**. If radius indication is not accurate then refer to Radius Settings. 2.6b Radius Settings 1. Go to menu 4) INSTALLATION and select 4C) RADIUS SETTINGS. 2. Enter the user password and press Enter. 3.
