Connect the Emergency Stop Circuit

The Emergency Stop Circuit on the press must be properly wired to the MicroCoat System to prevent the press

from stamping without lubricant and to alert the operator if the lubricant pressure drops below 0.69bar (10psi).

These switches must also be wired in series with the Emergency Stop Circuit from the press. Following integration

of this circuit, the end user should review and test the fail-safe operation by turning off the MC800 system pressure

switch. The press should not be able to start with this switch in the off position.

WARNING

Connect the red and black wire to the Emergency Stop Circuit located on the press.

System Setup

Check All Connections

1. Check that all connections are correct and secure.

2. Verify that the System Pressure switch is set to the Off

position and the mode switch is set to the Auto/Run

position.

3. Check that the input air supply is connected and set at

4.14bar (60psi).

Fill the Tank Reservoir

Do not overﬁll. Overﬁlling may cause lubricant to ﬂow back

into the regulator in the regulator in the controller.

CAUTION

1. Unscrew the tank cap and ﬁll the tank reservoir with

lubricant to the level indicated on the tank label.

2. Reinstall the tank cap.

Prime the System

1. Set the System Pressure switch to On.

2. Adjust the Tank Air Pressure regulator to 1.03bar (15psi).

Do not set pressure lower than 0.83bar (12psi).

3. Turn the Nozzle Air pressure regulator knob

counterclockwise as far as it will go to prevent nozzle air

from ﬂowing while priming the valves.

NOTE: Regulator knobs have a push-to-lock, pull-to-

unlock feature.

4. Turn all Flow Control knobs completely clockwise until

closed.

5. Set the mode switch to Manual/Setup.

6. Open the valve on the ﬁlter adapter until all the air is

removed.

7. Check for leaks around the ﬁlter and all connections

between the tank and controller.

8. Select one valve and open the appropriate Flow Control

knob about ﬁve full turns (counterclockwise) to ﬁll the

hose and prime the valve.

9. When the lubricant ﬂows in a steady stream, the valve is

primed. Close the Flow Control (turn clockwise).

10. Repeat steps 8 and 9 for each valve.
