Oil level monitoring OLC-K1

OLC-K1 is an opto-electronic oil level monitoring using infrared light. It consists of

a prism unit (screwed into the bearing cover) and
an opto-electronic unit (screwed into the prism unit, is integrated into the control of the system).

The oil level monitoring activates 90 s after compressor start. This time bridges any oil fluctuations due to starting conditions. During operation, the compressor is switched off by the oil level monitoring after 5 s without a detectable oil level.
