5. Detecting the Level of Fixing Oil
The level of silicone oil inside the upper oil pan is monitored by the oil level sensor (PS6). The float
floating on the silicone oil moves up and down according to the level of the oil, enabling the oil level sensor to
detect the level in reference to the moving arm.
If the oil level sensor does not detect the arm at power-on, the oil pump solenoid repeats turning on and
off until the arm is detected. If the arm is still not detected after operating the oil pump solenoid for 10 min, the
'Add Oil' message will be indicated on the control panel.
