How the System Operates
The MicroCoat System incorporates up to eight low volume low
pressure (LVLP) spray valves, a lubricant reservoir, and a controller
that regulates air pressure, meters lubricant flow, and controls valve
operation.
Constant air pressure applied to the tank reservoir forces lubricant
through precision fluid flow ]controls on the MC800 controller, then out
to the spray valves.
When the press is stamping, a 3-way air solenoid activates the system
and opens the valves.
As the valve opens, LVLP air creates a pressure drop at the nozzle,
causing the lubricant to spray a fine film onto the stock.
Lubricant flow can be adjusted independently for each valve via flow
controls on the front of the MC800 controller.

Controller Features
1. System Pressure Switch
Turns the system air supply On and Off.
2. Mode Switch
Use Manual/Setup position to prime and test the valves
without running the press.
In the Auto/Run position, the system will spray lubricant
when the press begins stamping.
Press air solenoid must be properly installed to allow
the MicroCoat System to run in Auto/Run mode (refer to
pages 18–19).
3. Tank Air Pressure
Regulates air pressure in the lubricant reservoir. For
most lubricants, 1.03bar (15psi) is a good start.
Minimum setting is 0.83bar (12psi).
4. Nozzle Air
Regulates nozzle air pressure.
Average setting is 0.55 to 0.83bar (8 to 12psi). Higher
pressure provides finer spray.
5. Flow Controls
Provide independent flow control of the lubricant to
each spray valve. Each blue ring on the stem coming
out of the middle of the knob indicates one complete
revolution.
Turn counterclockwise to increase flow.
