The TK3+ is designed to control the oil level in the compressor crankcase to improve its lifetime.
The TK3+ is designed to control the oil level in the compressor crankcase in order to avoid the compressor to run without oil and so improve its lifetime. TK3+ monitors the oil level with the embedded electro-optic sensor and comprises a solenoid valve for oil filling and a relay output contact to give an alarm or directly stop the compressor (through a separate power relay).
The output contact (normally open) is closed when the oil level is enough and open if after a determined number of filling cycles the oil level is not restored. Alarm state is represented by the red LED.
The LEDs on the Electronic module give immediately info on the status of the system and act as follows:
Power Light (green colour): always on when power is applied.
Oil Good (green colour): steady on while oil level is good, blinking for a first period of oil missing (even due to turbulence, undulations, etc.) before start filling and is off when filling.
Oil Filling (yellow colour): Off while oil level is good, steady on while injecting oil, blinking while (after filling) TK3+ check if the oil level is restored.
Alarm (red colour): Off while oil level is enough, steady on if after a determined number of filling cycles the oil level is not restored.
Filling cycles continue also in alarm condition and in each phase, if the correct oil level is restored, the oil feeding is stopped and the alarm is deactivated (auto restore from alarm).
