The prism unit of OLC-D1 is mounted instead of a sight glass:

  1. Unscrew the union nut.
  2. Remove sight glass.
  3. Check if glass cone of prism unit is clean on inside and outside and clean if necessary.
  4. Insert the gasket.
  5. Put on the prism unit and tighten it with the union nut.
  6. Test pressure equipment tightness.
  7. Mount the completely dry opto-electronic unit. Carefully push the opto-electronic unit into the prism unit as far as it will go.
  8. The OLC-D1 locks out if the opto-electronic unit is not installed completely. In this case the red LED at the OLC-D1 flashes.
  9. Firmly tighten the screwing cap manually.
  10. Ensure that the cable connection always points downwards.

For technical data see enclosed manufacturer's information.

If the liquid level should be monitored via a sight glass in addition to the opto-electronical monitoring, a Rotalock T-joint must be mounted in place of the sight glass. See following figure.
