Operation

Theory of Operation 

Air is constantly being applied to the air/oil blocks. After 
a preset Pause (off) Time, the controller activates the 
pump. The green “Power ON” LED (D) lights. System 
pressure builds causing the piston distributors within the 
air/oil mixing module to fire. The “No OIL” pressure 
switch closes.

The output from the piston distributor is discharged to 
the air/oil mixing chamber where the constant flow of air 
causes a thin film of oil to flow along the delivery tube in 
a constant, wave-like motion. This film is then applied in 
the form of a very fine spray from a drilled orifice or noz-
zle tube to the bearing elements on a constant basis.

If the oil pressure switch closes before the expiration of 
set Work Time, the pump and “Pump ON” LED (C) turns 
off and the timer begins its count down to the next lube 
occurrence.

If the oil pressure switch does NOT close before the 
expiration of the set Work Time, a fault is registered, 
causing a red “Alarm” LED (E) to light. The Fault Alarm 
contacts to transfer. The “Pump ON” LED (C) and pump 
turn off.

Other System Faults

NOTE:

 If a fault occurs, press the Manual Run/Rest but-

ton to clear the fault and restart the pump. The pump will 
not start until the fault is cleared.

Startup Procedure

1. Verify the pressure regulator set point for the air/oil 

mixing blocks; the bearing should be receiving air.

2. Repeatedly press the manual run button (B) (allow-

ing approximately 5 seconds of OFF time between 
cycles). 

3. Verify oil output from each of the air/oil mixing 

blocks.

NOTE: 

This step also ensures that the inside of the 

air/oil delivery lines are coated with oil.

4. If a Timer is used, verify the cycle time.

5. Allow the system to stabilize for 15 minutes; then 

check the air/oil lines to ensure that oil has reached 
the bearing.

6. Start the spindle.
