The Topcon grade and slope system may not perform properly if the valve offsets are set with the machine oil temperature a 37.8 (C (100 (F) and then the hydraulic oil increases to 82.2 (C (180 (F). The current that is required to shift the grade control valve spool increases as the oil temperature increases, due to an increase in coil resistance. This problem can be recognized by the system's up/down arrow remaining on and the control not making the grade change required. Solution:
The system configuration of 24 volts proportional is controlled by a resistor in the tractor to screed cable. In order to configure the machine to ON/OFF will require the configuration value and other values to change in the technician's menu. The following values should be used for ON/OFF. Record all setting prior to changing the system to ON/OFF.Reference: Reference the Topcon OMM KEBU7009 and access the technician's menu.The below settings will allow the system to pulse the valve in the ON/OFF configuration. BOLD SETTINGS ARE NEW FOR ON/OFF.9An = Grade Gain, set at 20.9An = Slope Gain, set at 20.SLP = Slope Resolution, set at .1%.SS = Sonic Averaging Ski, set to OFF, unless the SAS ski is being used set ON.db = Dead Band, set at 003.OFS = Valve Offset, set between 27 and 32 the higher the number the faster the cylinder speed. Adjust the offset until the cylinder speed is one- inch travel in 13 seconds. Higher offset than above can cause the system to overshoot.UnE = Units, set at in or cm.Ser = Stringline, set at ON.FrE = Frequency, set at 07.0.Con = Configuration, set at 9.AU9 = Averaging, set at 10.Rp = Ramp Time set at 4.0.ECO = Temperature Cut Out, set at 0.LOC = Lock, set at ON.RPd = Ramp Distance, set at .07. Reference numbers for Proportional factory settings are listed below.9An = Grade Gain, set at 20.9An = Slope Gain, set at 20.SLP = Slope Resolution, set at .1%.SS = Sonic Averaging Ski, set to OFF, unless the SAS ski is being used set ON.db = Dead Band, set at 003.OFS = Valve Offsets, set between 350-400 while the higher the number the faster the cylinder speed. Adjust the offset until the cylinder speed is one-inch travel in 13 seconds. Higher offset than above can cause the system to overshoot.UnE = Units, set at in or cm.Ser = Stringline, set at ON.FrE = Frequency, set at 05.0.
