Introduction
The Oil Level Monitor is designed to oversee the oil level in plant compressors. It activates an oil injection output to pulse charge the system with oil if a low level is detected while the compressor is running. This process continues until the oil level is restored. If the low oil condition persists for over 105 seconds, the system deactivates the oil injection and oil healthy outputs, stopping the compressor. A reset button can return the compressor to a normal state. Six LEDs provide status indications.
