The Automatic Lubrication System (ALS) is a system that delivers controlled amounts of lubricant to multiple locations on a machine while the machine is operating. It has a float switch that can detect the oil volume. When the oil is lower than a set level, the float switch will send a continuous signal automatically and the buzzer will alarm.

CEN04 type has a timer, which controls the operation and interval time. It has operation, abnormal and interval indicators that is in the open and allows for easy monitoring and adjusting.

This model also features a pressure gauge where an operator can check the pressure easily.

The CEN04 model has a pressure switch device which has been set as 8kgf/㎝². This ensures that a decent volume of oil reaches the lubrication points on the machine and helps ensure that pipes remain unblocked. The standard specification is NC (Normal Closed) contact, which means that if the pressure is abnormal, it will give a signal to pump more oil.
