10. ng The OLC Kl is used for contactless oil level monitoring in compressors in order to safeguard sufficient lubrication of the internal mechanics As the refrigerant can be absorbed by oil fluctuation of the oil level in the compressor is common in refrigeration systems and thereby oil levels need to be monitored OLC K1 is for compressor use and locks out if oil level is not sufficient after 90 seconds of compressor operation 4 3 Level monitoring in vessels The OLC DI is meant for level monitoring in vessels and does not have the operation recognition input needed for compressor operation The OLC DI releases the relay if the level is too low and activates the relay if the level is valid There is a 5 seconds time delay between switching the relay 4 4 Red LED status light At start up the OLC will flash shortly with the LED After approx 3 seconds the relay will be activated For OLC DI the level monitoring starts immediately for the OLC KI monitoring starts when the DI signal is applied and after the 90 seconds delay time the level is evaluated Page 6 If the oil level is too low or there is a failure the relay will be opened and the LED will signal the failure LED Off Oil level good no failures LED On Oil level low LED flashing OLC not correctly mounted or Supply voltage too low or Internal failure Technical manual OLC DI OLC K1
