Check the pneumatic unit

WHAT YOU NEED 

Standard Personal Protective Equipment

  1. Visually inspect the pneumatic unit for signs of damage.

  2. Inspect the moisture traps for excessive moisture in the airline. If these are full, please empty and consider using a dryer air supply.

  3. Check that the pressure is set to around 70-80 psi on the main regulator.
  4. Check that the pressure is set to around 70-80 psi on the Z‑axis counterweight cylinder regulator (purge balance regulator). Make sure there is a slight positive and constant pressure from the purge lines in front of each feeder photoelectric sensor. Slightly re-adjust the Z‑axis counterweight cylinder regulator if necessary.
  5. Check that the pressure switch is set to 0.4 MPa.
  6. Turn off the pneumatic isolation switch and ensure that this triggers the alarm.
  7. Check for leaks around the regulators and associated components.
