Traxoil Electronic Oil Level Controls Operation

TR4 and TR5 are fully level controlled. The sight glass of each device is divided into three operational zones. When the level reaches the yellow zone (Yellow) the TR starts filling after a time delay of 10 sec. A further level drop to the red zone (Red) will switch the alarm relay after a time delay of 20 sec/120 sec. The current status is indicated with the 3 LEDs according to the following table:

Operating Condition/Status Function Contact Position LED
Supply power is off or normal oil level (<50%) OK BK-BU close
BK-BN open
Oil Level (close 40%) Injection Green
Oil Level < 40% Injection Yellow
Oil level too low < 30% Alarm + Injection BK-BU open
BK-BN close
