  • Page 7 Instruction book Safety precautions Safety icons Explanation Danger to life Warning Important note Safety precautions, general General precautions 1. These recommendations apply to machinery processing or consuming air. Processing of any other gas requires additional safety precautions typical to the application, which are not included herein. In addition to normal safety rules, which should be observed with stationary air compressors and equipment, the following safety directions and precautions are of special importance.
  • Page 8 Instruction book 11. Any modification to the compressor should only be performed in agreement with Quincy and under supervision of authorized, competent personnel. 12. If any statement in this book, especially with regard to safety, does not comply with local legislation, the stricter of the two shall apply.
  • Page 9 Instruction book 13. Never drill holes in an electrical cabinet. Small metallic burrs can cause short-circuits in electrical components. 14. Make sure to avoid condensation on electrical components (e.g. cubicle, electronic regulator and frequency converter). 15. To preserve the protection degree of the electric cubicle and to protect its components from dust from the environment, it is absolutely necessary to use a proper cable gland when connecting the power supply cable to the compressor.
  • Page 10 Instruction book 4. Never operate the machine when there is a possibility of taking in flammable or toxic fumes, vapors or particles. 5. Never operate the machine below or in excess of its limit ratings. Check the Limitations or Compressor Data section for the ratings. 6.
  • Page 11 Instruction book 4. All maintenance work, other than routine attention, shall only be undertaken when the unit is stopped, the main power supply is switched off and the machine has cooled down. 5. Take precautions to ensure that the unit cannot be started inadvertently. 6.

  • Page 21 Instruction book Regulating system General The Q-Control controller keeps the net pressure within programmable pressure boundaries by automatically loading and unloading the compressor depending on the air consumption. During unloading If the air consumption is below the compressed air delivery, the net pressure increases. When the net pressure exceeds the upper limit of the working pressure (unloading pressure), solenoid valve (Y1) is de- energized.
  • Page 22 Instruction book The compressor runs unloaded causing zero air delivery. During loading Once the net pressure is below the lower limit of the working pressure (loading pressure), solenoid valve (Y1) is energized. This forces the plunger of solenoid valve (Y1) against spring force, opening the control air supply port to unloader (UA).
  • Page 23 Instruction book Additional attention Breather /PSTST air • Customer must install an extra air supply (press. 4 - 11 bar (g), normal capacity 30-70 l/min). • Air must be clean and dry. • Customer should install pressure gauges on the conduit where air is supplied (1), to ensure the pressure when the compressor starts.
  • Page 24 Instruction book 3. Q-Control Touch 3.1 Controller Figure 1: Q-Control Touch Introduction The controller has following functions: • Controlling the unit • Protecting the unit • Monitoring components subject to service • Automatic restart after voltage failure (ARAVF) Automatic control of the unit The controller maintains the net pressure between programmable limits by automatically loading and unloading the unit (fixed speed units) or by adapting the motor speed (units with frequency converter).
