The preventative maintenance that I followed today is Bailey Infi90 power supply monthly inspection. I and Mr. Tai need to check the indication lamp and voltage measurement. If the indication lamp is green, the device is fine. If the indication lamp is red, the device needs to repair. For the voltage measurement, we need to note down the voltage of +15V, -15V, 48V, 24V and 5V for each connection in the PCU power supply.
In the evening, En. Sharif asked me to help the electrical section to wash the motor of the air compressor. I used the chemical (synthetic isoporaffinic hydrocarbon) to clean the stains on the shaft of the motor.
