1.1
1.1 Overview
Overview
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 two-
block 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).
1.2
1.2 Start-Up
Start-Up
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
LSI representative or LSI
LSI technical support
representative.

2.1a Mounting Bracket
1. Determine the mounting location; the display
may be installed either inside or outside the
cab. It can be mounted on the dash, on a
sidewall, or on the ceiling of the cab. To ensure
reliable radio communication between
sensors and the GS820, the antenna should
not be in contact with metal and should
have a direct and clear line of sight to the
sensor antenna. The mounting bracket
requires a flat surface of at least 2.5 inches in
diameter on both sides and where the back of
the surface is accessible in order to tighten the
nuts.
2. Drill 1/4 inch boltholes through the mounting
surface with a 1/4 inch bit following either the
two, three, or the four holes configuration.
3. Install the display with bolts. Add washers and lock
nut behind the mounting surface and tighten
sufficiently (bolts, nuts and washers not included).
4. Loosen the wing nut of the bracket arm to adjust
display orientation to facilitate viewing by the
operator and then tighten it back up.

IMPORTANT!
Do not crack or puncture
the membrane fascia. The GS820 display is
splash and rain proof. Waterproofing depends in
part on the integrity of the membrane.
IMPORTANT!
Do not power wash the
display. The GS820 display is not designed to
withstand high-pressure washing devices that
can erode the membrane fascia seal or create
fissures in the membrane fascia. Power washing
the display voids warranty coverage.
!
!
Note: If the nuts are on the outside of the cab,
caulk with silicone between the washers and the
cab to prevent water entry.
WARNING!
Installation must be made in
compliance with LSI
LSI instructions and using
LSI
LSI supplied components only. Failure to
install all parts, or replacing parts or
components with parts or components not
supplied by LSI

2.1b Antenna Position
For optimal performance the antenna should be
positioned on its side such that it is parallel to
the sensor antennas (but not pointing directly to or
directly away from them).
1. Adjust the antenna position with the articulating base.
2. The antenna should have 5 inches of clear
space all around it.
3. The antenna should have an unobstructed line of
sight to all sensor antennas at all boom angles.
2.1c Power Supply and Lockout
Connection
1. Connect the black wire (ground) to the negative
terminal of the battery or the panel connection;
alternatively bolt the black wire to the body of
the machine with a 1/4 inch or 5/16 inch bolt.
The ground connection must be strong enough
to sustain 3 amperes.
2. Connect the red wire to a fused accessory
source, rated at least 3 amperes, that supplies
+12 or +24 volts when the machine is in use.
The GS820 will automatically detect the voltage
level and adjust itself.
3. Lockout number 1 (if required): connect the
white wire to a Bosch relay coil terminal.
Connect the other coil terminal of the relay to
the ground. When operating properly the white
wire will energize at the battery positive level.
Current over 1 ampere on the white wire
triggers an auto re-settable fuse. Current flow
will resume several seconds after the short
circuit is eliminated.
4. Lockout number 2, 3 and 4 (if required): these
wires function in the same way as the white wire
described in step 3 above. Each lockout wire
can be triggered by a different set of alarm
conditions; see the Lockout Settings sub
section of this manual.
5. Connect the yellow cable to the GS820. The
connector is waterproof and well rated for
external environments. Simply connect the
cable to the display and gently tighten the nut.
Do not put a kink in the yellow cable where
it enters the connector; any bend in the cable
at the base of the connector must not be so
severe as to break the internal connections
where the cable meets the connector. The
power cable requires about 4 1/2 in. behind
the display to protect the connector.

Lockout relay inversion. 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.
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.

2.2 Load Cell
Load Cell
1. Install load cell bushings as supplied by LSI
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
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.
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.
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)

2.3 Angle Sensors
Angle Sensors
2.3a Mounting Procedure
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
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. Install the welding pads; keep the angle sensor
at least three feet from the weld site and any
connecting metal objects while welding.
3. Mount the angle sensor to the weld pads with
the screws and washers provided.
4. Verify angle indication on the GS820 LCD.
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.

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.
!
!
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.
!
!
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.

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.
4. Pivot the angle sensor slightly until angle
indication is correct. Repeat the angle validation
(step 1) as required.
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. 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 sensor
to 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 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.
8. Press Enter to save changes.
9. Press Exit to return to the operation display.
10.Verify accurate angle indication at both very
high and very low angles.

2.4 Anti-Two-Block Switch
Anti-Two-Block Switch
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
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.
Bolt or weld securely.
Figure: Angle Calibration Procedure № 2
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.
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 anti-
two-block switch and render the anti-two-
block system unsafe.
!
!
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.

2.4c Chain length adjustment
1. Chain length adjustment № 1 – minimum boom
angle
a. At minimum boom angle, with no
additional weight on the hook block and
one part of line only, lift the boom just
enough to have the hook block suspend
and clear the sensor chain and weight.
b. Hoist slowly until the buzzer sounds. Note
the hoisting distance remaining; this
distance must be great enough to allow
the operator and the lockout system, if
installed, to prevent a two-block event. If
necessary, add chain between the sensor
and weight to increase warning distance.
If still insufficient, contact your service
representative.
2. Chain length adjustment № 2 – maximum boom
angle
a. Raise the boom to the maximum angle.
b. Hoist slowly as described in Step 1.b. Verify
that the warning distance is equal to or
greater than that determined at the
minimum boom angle.
3. Chain length adjustment № 3 – speed test:
Lower the boom until the weight height becomes
visually clear to the operator. Repeatedly create
two-block, progressively hoisting faster, to
ensure that the warning and lockout work within
acceptable amount of time and distance.

2.5 Length Sensor Cable Reel
Length Sensor Cable Reel
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.
2.5a 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.
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.
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.
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.
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

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.

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
length may differ from the actual length.
