Overview
The GS550 system includes the cabin mounted GS550 radio display and compatible crane
mounted sensors. The GS550 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 indicated to the operator in real time. Working load radius can be
calculated and compared to a rated capacity chart (if programmed). Furthermore the GS550 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 GS550 system depends on the sensor configuration
used and the rated capacity charts programmed (where applicable). The GS550 includes an
infrared port to facilitate software and chart updates and data logger downloads using a compatible
palm or cell phone. Compatible sensors include the GS050 anti-two-block, the GC series load cells
and GS001 series line rider and load pin transmitters, the GS010 angle sensors, the GS011 angle
sensor and length transmitter and the GS020 wind speed sensor. The GS550 system is designed
as an operator aide and is in no way a substitute for safe operating practice.

Start-Up
The GS550 must be correctly programmed for the system sensors installed. The GS550 powers up
with several green lights flashing, this indicates that the display is waking up programmed sensors
and creating a radio communication link with each. Once a reliable radio communication network is
established, all green lights will remain lit without flashing.
This process may take up to one minute. The delay is created by the battery management function
and does not affect system security. If an anti-two-block switch detects a pending two-block event,
if a load cell detects a change in load, or if an angle sensor detects a change in angle, the
appropriate radio link will be established in less than 0.1 seconds. To immediately wake-up a load
cell, lift the hook with a load; to immediately wake up an angle sensor, change the boom angle.
In special conditions of lockout created by a missing sensor, you may bypass that sensor until the
next display power up by pressing bypass for 10 seconds. That sensor green light should stop
flashing and then turn off.

2 Block
The red 2 Block alarm light comes on when a programmed anti-two-block switch is in alarm.
The green “M” (main) and “A” (auxiliary) anti-two-block radio status lights stay on when the
GS550 has a reliable radio communication link to all programmed anti-two-block sensors.
The radio status lights flash green when communication is intermittent or absent. The M
refers to the first anti-two-block sensor programmed in the sensor list. The A refers to all
other anti-two-block sensors programmed in the sensor list.
Load
The red Load alarm light comes on when a load sensor is in overload.
The green “M” (main) and “A” (auxiliary) load radio status green lights stay on when the
GS550 has a reliable radio communication link to all programmed sensors. The radio status
lights flash green when communication is intermittent or absent. The M refers to the first
sensor programmed in the sensor list except anti-two-block. The A refers to all other sensors
programmed in the sensor list except anti-two-block.
Low Battery
The amber light of the battery icon comes on when battery life for a sensor programmed in
the sensor list drops below 10%. Normally several weeks of battery life remains from the
moment the low battery light first comes on.
Bar Graph
The bar graph displays the gross load lifted by a load sensor as a proportion of the maximum
load allowed, expressed in 10% increments. Maximum load is the lowest of the operator set
maximum load limit and the working load limit (WLL) as calculated from the rated capacity
charts*. When there are two or more load sensors programmed in the sensor list the bar
graph will indicate the load for the sensor closest to its maximum allowable.
Infrared Port
The infrared port is used to download data from the data logger or to upload firmware updates and
capacity charts using a GT103 portable download tool or other compatible device.
*
WLL is indicated by rated capacity indicators only.

Crane Rigging – Capacity Chart Selection
The GS550 can be programmed to assist the operator by indicating the working load limit (WLL)
from the crane specific rated capacity charts according to the angle and radius information
received from the boom mounted sensors. Under no circumstances is the GS550 a substitute for
safe operating practices. The operator must fully understand the crane rigging and the crane rated
capacity chart to be able to correctly program the GS550 for rated capacity indication. The GS550
will not take into account critical variables such as weather, ground and crane conditions that will
reduce the safe working capacity of the crane.
In order to indicate WLL the GS550 must be programmed with a valid rated capacity chart specific
to the crane. The capacity chart programmed can be verified on the chart number page of the
Information menu: press Info → Next → Next (press Exit to return to the operation display). If the
chart number information screen says “Chart not loaded” the GS550 has not been programmed to
function as a rated capacity indicator. If rated capacity indication is required contact the person
responsible for the GS550 system installation and maintenance. If in doubt, contact LSI.
Rated capacity indication is based on interpretation of a selected capacity chart using boom angle
and load radius. This requires:
Installation: The GS550 must be programmed for a correctly installed boom angle sensor
and a radius sensor. Additionally a length sensor will be required for telescopic booms;
luffing jibs may require an angle sensor. Furthermore, the GS550 must be programmed with
accurate mounting point dimensions for the head sheaves, jibs, extensions and other
structures that will determine working load radius for each of the hoist lines used; reference
menu 4C) Radius Settings.
Operation: The chart must be selected by “rigging” the working sheave in the GS550; this is
done by following the chart wizard in menu 2) Crane Rigging.
The Chart Wizard
Important! It is possible to leave the chart wizard at any time by pressing Bypass; the
GS550 will display the message “Rigging ABORTED”. Current capacity chart selection
may have changed, possibly changing the rated capacity indicated by the GS550.
Always complete the chart wizard all the way to the “Rigging ok” message before
operating the crane.
Step 1. Press Menu → Next → Enter to start the chart wizard.
Step 2. The first page of the chart wizard is generally “select sheave”. Use Up and Down to
adjust the sheave number. If the there is only one load sensor in the system leave the
sheave value at one. With two or more load sensors in the system sheave one (the
main hoist) is associated with the first load sensor in the sensor list; sheave two (the
auxiliary) is associated with the second sensor in the sensor list etc.
Step 3. Press Next to advance to the next step of the chart wizard.
Step 4. The steps that follow will depend on the size and complexity of the rated capacity chart
itself. Typical steps include chart selection, outrigger / on rubber selection and boom
length selection (lattice cranes only). Use Up and Down to select from the list of
choices and then press Next to advance to the next step. For accurate rated capacity
indication the rigging configuration selected in the chart wizard must reflect the actual
rigging of the working sheave.
GM550 v1043 FCC-IC.doc Revision 2 15
Step 5. After the last step has been completed the GS550 will display “Rigging ok” and then it
r
will return to the operation display. If a sensor required by the selected capacity chart is
not a part of the system or has not established communication with the GS550, then
the GS550 will display “sensor invalid”.

Installation
Display GS550
Important! Do not crack or puncture the membrane fascia. The GS550 display is splash
and rain proof. Waterproofing depends in part on the integrity of the membrane.
Important! Do not power wash the display. The GS550 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.
Mounting Bracket
Step 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 GS550, the antenna
must not be in contact with metal and must have a direct and clear line of sight to the
antennas of all sensors. The mounting bracket requires a flat surface of at least
2 inches in diameter on both sides and where the back of the surface is accessible in
order to tighten the nuts.

Step 2. Drill ¼ inch boltholes through the mounting surface with a ¼ inch bit following either the
three, or the four, hole configuration.
Step 3. Install the display with the supplied bolts. Add the washers and the lock nut behind the
mounting surface and tighten sufficiently.
Tip: If the nuts are on the outside of the cab, caulk with silicone between the washers and the cab
to prevent water entry.

Step 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.

Power Supply and Lockout Connection
Step 1. Connect the black wire (ground) to the negative terminal of the crane battery or the
panel connection; alternatively bolt the black wire to the body of the machine with a ¼ inch or
5/16 inch bolt. The ground connection must be strong enough to sustain 3 Amp.
Step 2. Connect the red wire to a fused accessory source, rated at least 3 Amps, that supplies
+12 or +24 volts when the crane is on. The GS550 will automatically detect the voltage level
and adjust itself.
Step 3. Lockout number 1 (if required): connect the white wire to a Bosch relay coil. Connect
the other terminal of the relay to the ground. When operating properly the white wire will
energize at the battery positive level. Troubleshooting; if no voltage is present on the white wire
remove the load connected to the lockout. Current over 1.5 Amps on the white wire triggers an
auto re-settable fuse. Current flow will resume several seconds after the short circuit is
eliminated.

Step 4. Lockout number 2 (if required): the green wire functions in the same way as the white
wire; see above. The green wire lockout signal could be triggered by a different set of alarms
than the other lockout wires. See lockout code table on the next page.
Step 5. Lockout number 3 (if required): the orange wire functions in the same way as the white
& green wires; see above.
Step 6. Optional Lockout number 4: if purchased with the fourth lockout option, the blue wire
will function in the same way as the white & green wires, see above.
Step 7. Connect the yellow cable to the GS550. 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.
