OM6011 10/11 VHMS - Section 60 Page 60-1 VEHICLE HEALTH MONITORING SYSTEM (VHMS) The VHMS system is a machine management sys- tem. The VHMS controller gathers machine data sent from the other controllers and sensors installed on the machine. The data stored in the VHMS controller is sent via personal computer or sent automatically through a communications satellite (optional) to Komatsu. The data is compiled in the Komatsu com- puter server and analyzed. The VHMS system uses wireless components that transmit via radio waves. It is necessary to conform to local laws when using this system.
Based on the machine data, your Komatsu distributor will provide information aimed at reducing machine repair costs and downtime. Proper operation of the system is dependent on good reception. Operating in tunnels, mountain ranges and covered areas may prevent communi- cation of the system. NOTE: A contract is necessary before the VHMS system can be used. Contact your Komatsu distributor for more information. Contact your Komatsu distributor before selling or exporting a truck equipped with VHMS. It may be necessary to remove the system before trans- fer of ownership. Contact your Komatsu distributor before install- ing equipment that may interfere with the VHMS system.
DO NOT disassemble, repair, or modify the VHMS system without proper authorization. Changes to the system may cause machine failures and fire. Komatsu is not responsible for any failures that result from neglecting VHMS system precautions and instructions. DO NOT touch VHMS system components during machine operation. DO NOT pull on VHMS system wiring harnesses, connectors, or sensors. This may cause short circuits or open circuits and lead to machine fail- ure or fire. Orbcomm is a two-way radio communication device. Wireless signals from the system can interfere with other wireless signals in the area.
This interference can cause a malfunction in a blast zone resulting in an unintended detonation. Know the locations of blast zones in the area and keep a safe distance to avoid unintentional blasts. If the machine is operating within a dis- tance of 12m (40 ft) of a blast zone, disconnect the Orbcomm harness. Failure to do so could result in serious injury or death. DO NOT allow water, dirt, or oil onto system com- ponents. The Orbcomm satellite requires the installation of a pole and antenna, adding to the overall height of the machine. The height increase is 410 mm (16.2 in.). With the guard installed, the overall height increases another 260 mm (10.2 in.).
Use caution when operating in areas with height restrictions. This warning does not supersede requirements or regulations of the area or country where this machine is in operation. The following specifica- tions are provided to ensure compliance with all of the applicable requirements or regulations: Anyone with a pacemaker must remain a mini- mum of 22 cm (9 in.) from the communications antenna. Radio waves from the antenna can interfere with pacemaker operation. Transmit power: 5-10 Watts Operating Frequency Range: 148 - 150 MHz
