➜ In general, all installation works must be done by a dedicated installation specialist. Please contact the local selling unit or dealer for further information.
The installation information within this User Manual is indicated to increase the operators understanding of the system and its maintaining.
Before installation:
• Please observe the maximum vibration and ambient temperature values indicated in chapter 7 Technical Data.
• Check that all parts needed are delivered. Refer to 2.2 Unpacking the Container for further information.
• It is strongly recommended that you bench test all components before commencing installation on the actual machine to make sure that all components are fully operational.
Installation of GNSS instrument
For best results, it is recommended to mount the two GNSS antennas according to following guidelines:
• separated as far as possible,
• at approximately the same height,
• with the connectors orientated in approximately the same direction
• ensuring an unobstructed view of the sky.
Installation on an excavator:
• Install the two GNSS antennas on the masts in the back of the machine.
• One mast should be placed on each side of the machine. Be aware of heat from the exhaust.
Cable installation
• Ensure that the cables between iCON gps 120 and CR50 in particular are installed such that they are not bent or stretched.
• It is recommended to use strain relief brackets.
• Route the cable as directly as possible and avoid crossing cables.
• Be sure not to tie the cables onto “hot” hydraulic hoses.
• When installing or removing a cable, align it carefully with the connectorto prevent any risk of bending or breakage.
Fastening
Electrical grounding
The electrical grounds of a Machine may be at different potentials either due to other large current electronic devices on the machine or when different grounds of the machine are isolated in service or welding operations.
Different DC and RF noise may exist at different points in the machine which is out of the control of Leica Geosystems. Such noise may have a negative effect on the satellite tracking performance of the iCON gps 120.
For this reason, it is best that the GNSS antenna(s) are isolated from the machine. This avoids additional ground paths being introduced.
➜ In an ideal installation, with isolated antennas, the connection of the grounding pin on the rear panel of the iCON gps 120 to the machine should not be required.
➜ It is extremely important to disconnect all cables from the iCON gps 120 before starting any welding operations on the machine. Otherwise the instrument may be damaged beyond repair.
