GS550 UNDERHOOK 1: Overview 1.1 Introduction The GS550 Underhook creates a two-way radio network with the sensors to bring required lift data to the operator. Hoist load can be detected and then indicated to the operator in real time. Furthermore the GS550 Underhook can be programmed to generate warnings and alarms, all triggered by adjustable thresholds and limits. The exact operational function of the GS550 Underhook system depends on the sensor configuration used.
GS550 UNDERHOOK 2: INSTALLATION 2.1 Display GS550 Underhook NOTE ✓ refer to the operation section, beginning on p. 7, for detailed menu navigation instructions for all calibration procedures. WARNING Installation must be made in compliance with LSI-Robway instructions and using LSI-Robway supplied components only. FAILURE to install all parts, or replacing parts or components with parts or components not supplied by LSI-Robway, may lead to system failure, serious injury or death. 2.
GS550 UNDERHOOK WARNING NOTE ✓ if the nuts are on the outside of the cab, caulk with silicone between the washers and the cab to prevent water entry. 2.2 Start-Up THE GS550 UNDERHOOK SYSTEM IS DESIGNED AS AN OPERATOR AID AND IS IN NO WAY A SUBSTITUTE FOR SAFE OPERATING PRACTICES. WARNING The GS550 Underhook must be correctly programmed for the system sensors installed. If a sensor is missing or has a problem, a message will be displayed on the GS550 Underhook.
GS550 UNDERHOOK 3: OPERATION 3.1 GS550 Underhook Display The GS550 Underhook displays detailed information on the backlit, two line liquid crystal display (LCD); warnings and alarms are also communicated by the display buzzer. Parts of line Hoist indicator USB Port 1 Tare Indicator Load 15000 915000 Bar Graph Indicates the load on the hoist as a percent of the working load limit. Tare Warning Light The total load is not displayed when tare light is on.
GS550 UNDERHOOK Alert: 3.1b Tare Zero the hook and rigging weight: • Press Tare to enter the tare menu. • Use Next to select the load sensor. • If no tare value is displayed, then press Tare to create a tare value equal to the weight on the load sensor. Example: with hook block and rigging only. Load display is net weight (gross weight minus tare value). • To remove a tare value, press Tare. • Press Exit to return to the operation display.
GS550 UNDERHOOK 3.1e Parts of Line The load sensor often shares the weight with multiple parts of line. For accurate load indication the GS550 must be programmed for the number of parts of line. 1. Go to menu 1) Parts of Line. 2. Use Next and Back to select the load sensor; typically sensor number one is associated with sheave one (the main hoist) and sensor number two is associated with sheave two (the auxiliary hoist) etc.
GS550 UNDERHOOK 3.4d GS550 Underhook Menu Outline Only sections relevant to Underhook operation have been listed. Menu levels with an asterisk (*) after the title are accessible to the operator without a password under the default factory settings.
GS550 UNDERHOOK 4: SETUP 4.1 Sum Load Indication 4.2 Sensor List When sum load indication is programmed the sum of the loads on the pre-determined load sensors is indicated by the operation display. To activate sum load indication program a “Sum load cell” in the sensor list. The “ID number” is used to identify the load sensors to be summed. Sum maximum limit. The maximum limit for the sum load can be adjusted in the limit menu; the default maximum limit for sum load indication is 10,000 lbs or 4,535 kg.
GS550 UNDERHOOK 4.2b How to Remove a Sensor from the GS550 Underhook 1. Determine the sensor to be removed. If more than one sensor of the same type has been added to the sensor list then determine the radio identification number (ID) of the sensor to be removed before proceeding. A sensor ID number between 10000 and 999999 is engraved on each sensor. 2. Go to menu page 4A1). 3. Press Next repeatedly to advance to the page of the sensor list showing the ID of the sensor to be removed.
GS550 UNDERHOOK 4.4 Data Logger The GS550 Underhook includes a data logger that records all significant events including actual sensor values and a date and time stamp. The data logger memory can hold over 16,000 records, equivalent to several days or several years of operation depending on the recording mode selected and machine use. The data can be extracted using a USB mass storage device (USB key) and then transferred to a personal computer for analysis. 4.
GS550 UNDERHOOK 4.5 Display Settings 4.5d Backlight Mode Program the display for operator preferences in menu 3) Display Settings. 4.5a Weight Units The weight units for load display may be selected according to operator preference. Length units are associated with weight units by default; see the table below. Adjust the LCD backlight control mode to conform to viewing and power supply conditions. 1. Go to menu 3A) Weight units. 2. Use Up and Down to select the weight units for load display. 3.
GS550 UNDERHOOK 4.6 System Diagnostic Diagnose system issues with the sub menus of menu 5) System Diagnostic. 4.6a System Sensors Diagnostic 1. Go to menu 5A1). 2. Use Back and Next to select the sensor. 3. Press Enter to see sensor data. 7. Press Next to go to menu 5D7) Radio. “FCC”, “IC” indicates Federal Communications Commission (U.S.A.) and Industry Canada certification, “CE” indicates European Community certification. The frequency used by the network is indicated on the second line. 8.
GS550 UNDERHOOK 5: USB TOOL Download data or upload capacity charts using a USB mass storage device (USB key). CAUTION the load cannot be monitored during the download process. before transferring (or downloading) data logger or firmware updates, make sure the crane/machinery is stopped and is in a safe state.
