Procedure

  1. Select [Functions] > [Mould Evacuation]
  2. Switch off the function with the slider ().
  3. Remove the hydraulic connections on the main line and return line lines.
  4. The pressure displayed by the pressure gauge must be 0 bar +0.3 bar.
  5. Select [Display] > [Actual Values] > [System Pressure]
    → The System Pressure     must display 0.0 bar ±0.1 bar.
  6. Select [Display] > [Actual Values] > [main line Pressure]
    → The Main Line Pressure     must display 0.0 bar ±0.1 bar.

Calibrate pressure sensor

  • If the deviation is >0.1 bar, the unit's pressure sensors must be checked. For larger linear errors, the individual pressure sensors can be calibrated → [Service] > [Calibrating] > [Pressure] > [Pressure sensor 1 Offset] or [Pressure Sensor 2 offset].
