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 |
● Green |
| Oil Level (close 40%) | Injection | ● Green ● Yellow |
|
| Oil Level < 40% | Injection | ● Yellow | |
| Oil level too low < 30% | Alarm + Injection | BK-BU open BK-BN close |
● Red ● Yellow |

⚠ Safety Instructions:
- Read operating instructions thoroughly. Failure to comply can result in device failure, system damage or personal injury.
- According to EN 13313 it is intended for use by persons having the appropriate knowledge and skill.
- In a severely contaminated system, avoid breathing acid vapors and avoid contact with skin from contaminated refrigerant / lubricants. Failure to do so could result in injury.
- Before opening any system make sure pressure in system is brought to, and remains at, atmospheric pressure.
- Do not exceed the specified maximum ratings for pressure, temperature, voltage and current.
- Before installation or service, disconnect all voltages from system and device.
