DS 350 G Boom Control Troubleshooting- TMS/TTS870 / RT865 BXL 4 Auto mode / Manual mode: The operator selects auto mode or manual mode using the rocker switch in the dash board. Auto mode is the working mode and manual mode is used for rigging or sequencing purpose only. Pilot pressure switch signal / Analog output signal: Two pressure switches in the pilot pressure circuit are used to distinguish between boom extend or boom retract.
DS 350 G Boom Control Troubleshooting- TMS/TTS870 / RT865 BXL 5 Length sensors: Three length sensors are mounted to the boom base section to measure the overall length, the inner mid section length and the center mid section length. The software utilizes the signals to calculate the outer mid and fly section length. Disengage the boom stop to retract the boom completely. With retracted main boom the overall boom length signal is -500 mV (A101-X1/10).
DS 350 G Boom Control Troubleshooting- TMS/TTS870 / RT865 BXL 6 Center mid retract and % reset switch: The proximity switch on the inner mid section provides a (+24V) signal to central unit terminal A 114 X1/9 when the center mid section is fully retracted. The signal resets the center mid percentage to 0%. Refer to Parts & Installation Manual and follow the installation instructions for switch and target adjustment.
7 DS 350 G Boom Control Troubleshooting- TMS/TTS870 / RT865 BXL Output for two- way valves: A pair of two- way valves controls the oil to each tele- cylinder. The relay output K2, K6, K7 operates the pair of two- way valves in automode. The valve need to be de-energized to operate the particular cylinder. The valves for the sections that are not selected are powered to prevent movement of the other cylinders.
DS 350 G Boom Control Troubleshooting- TMS/TTS870 / RT865 BXL 8 Rod side dump valve: Relay K3 controls the rod side dump valve. The valve dumps the rod side pressure when the controller is in neutral position and during the time the section stops while changing over to another section.
