The OptiStar Manual gun control unit is used for electrostatic powder coating with an Optiselect manual application gun equipment and OptiFlex B fluidizing vibrating box carrier

  • The OptiStar CG07 Manual gun control unit is designed exclusively for controlling the ITW Gema powder coating guns. 
  • The OptiStar Manual gun control unit allows the configuration of process parameters (air settings, high voltage settings), system parameters, process data, status information and the powder hose correction values. All air volumes can be controlled centrally by the unit
  • The handling is simple and self-explanatory
  • The coating operative can save individual settings based off personnel experience
  • All settings for efficient powder coating are simple to operate and repeatable. The control unit electronics permit the exact amount of powder delivery and the adjusted values can be read on the digital displays
  • The OptiStar CG07 Manual gun control unit can be connected to all usual mains voltages between 100-240 VAC, 50-60 Hz, single phase

Function description

  • Basic functions
  • Intuitive operation
  • Setting and display of the values on two levels
  • Saving/recalling of process parameters in the form of programs
  • Remote control option on the manual powder gun (OptiSelect GM02 only)

Additional functions 

  • Spray current regulation with high voltage limitation
  • Control of the air volumes
  • Controlling of the stirrer and the vibrator
  • Status indications and error diagnosis

Operating modes
Predefined operating mode (Preset mode)
The CG07 Gun control unit provides three predefined application modes (flat parts, complicated parts and recoat parts already painted one time). When operating in this mode, the spray voltage and spray current are automatically set and limited.
In this operating mode, current (µA) and high voltage (kV) are preset, powder and air volume can be adjusted and saved. The powder and air volume are stored separately for each predefined application mode.
User-defined operating mode (Program mode)
In this operating mode, 20 individually definable programs (P01-P20) are available. These programs are automatically saved and can be recalled again as the application requires.
The values for current, high voltage, powder output, total air, electrode rinsing air and fluidizing air (if available) can be set as needed for a given application.
