Hereby, Parker Hannifin Corporation declares that the radio equipment type 740 TGSS is in compliance with Directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following internet address under Product Support: https://ph.parker.com/us/17616/en/tgss-true-ground-speed-sensors... -
Page 12: Installation
Installation 2. Installation The TGSS is typically installed at a height of 0.3 to 1 meter (1 to 3 feet) above the ground. The maximum height of installation is 1.22 meters (4 feet). The sensor mounts to a bracket on the underside of the vehicle where the sensor may be directed in either the forward or reverse direction. -
Page 13: Mounting Bracket
[.250] Figure 4: Recommended mounting plate dimensions The TGSS has rubber shock absorber vibration mounts to reduce the effect of machine vibration. The vibration mounts have an internal M6 thread, the recommended installation torque is 5.4-7.3 Nm (48-65 in lbs). -
Page 14: Mounting Angle
The following guidelines are related to physically attaching the TGSS to the mounting bracket on a vehicle: ▪ The TGSS should be secured with bolts in all 3 bolt holes using 6 mm Hex Head bolts and locking washers. The bolts should be tightened to 5.4-7.3 Nm (48-65 in lbs). -

-3dB level and the larger region is the -10 dB level. These areas are the relative sensitivity of the TGSS to motion. The-3dB region is the area where the TGSS is most sensitive. This path must be clear of any objects. Interference in this area will have a high likelihood of degrading the performance of the product's ability to provide accurate speed measurement. - Page 16 The model is based on a mounting height of 1 meter. Any other height will require that the radar beam model be stretched ratiometrically with the new height. This is done by looking at the model as spherical coordinates and scaling the radius proportionally to the 1 meter in the model. TGSS...

Page 17: Installation Validation
With the vehicle stationary over a smooth surface, slowly sweep the engine rpm over it’s range. Monitor the TGSS speed output to see if any false speed is shown. If a false speed reading occurs, there is either a line of sight or vibration issue. -
Page 18: Performance Considerations
This will prevent undesired speed readings caused by external sources. 2.2. Performance Considerations The TGSS is a K Band radar. There are many factors that may influence its operation. ▪ The further the ground is from the radar, the lower the return signal strength. -
