5-6 Operation

5.9 Positioning the Robot

If necessary, the operator can use the ECXP to reposition the robot in the X-, Y-, and Z-axes.

To move the robot using the arrow keys:

1. Start the ECXP software. See 4.9 Starting Easy Coat for Windows (ECXP).

 The Operator Screen opens (Figure 5-3).

Figure 5-3 Moving the Robot

2. Use the keys on the computer keypad to move the robot as follows:

a. XY-Axis (Slow) – Hold down <Ctrl> and press the right and left arrow keys for X-axis

movement and up and down arrows for Y-axis movement.

b. XY-Axis (Fast) – Hold down <Ctrl> + <Shift> and press the right and left arrow keys for

X-axis movement and up and down arrows for Y-axis movement.

c. Z-Axis (Slow) – Hold Down <Ctrl> + <Z> and then press up or down arrow keys for

desired Z-axis movement.

d. Z-Axis (Fast) – Hold Down <Ctrl> + <Shift> + <Z> and press up or down arrow keys for

desired Z-axis movement.

5.10 Pneumatic Regulators and Gauges

The SL-940E/SL-941E Series Conformal Coating Systems have the following pneumatic regulators and

gauges:

• Main Air Regulator and Gauge

• Reservoir Pressure Regulator and Gauge

• Fluid Pressure Regulator and Gauge

• Conveyor Air Regulator and Gauge

The Main Air Regulator is located at the rear of the system (Figure 5-4). The Reservoir Pressure

Regulator is located inside the front cabinet (Figure 5-5). Fluid pressure is controlled through the ECXP

software (Figure 5-6).

WARNING! CAUTION!

Make sure the Safety Interlock Recovery Light located on the Front Panel is ON

before you access the inside of the dispensing area. When the light is OFF,

accessing the inside of the dispensing area will cause a non-recoverable

interlock condition to occur. Refer to Section 2 - Safety for additional information.

Recommended pressure settings are provided in Table 5-1. See detailed adjustment instructions following

descriptions in this section. See 4.12 Pneumatics for other regulator adjustments.

Table 5-1 Recommended Pressure Settings

Device Recommended Pressure Comments

Main Air Pressure Regulator 551 kPa (80 psi)

Facility pressure is 586 to 620 kPa

(85 to 90 psi).

Reservoir Air Pressure

Regulator

206 to 276 kPa (30 to 40 psi)

Recommended pressure depends on

fluid being dispensed and coating

applicator being used. Refer to the

Installation and Operations manual

applicable to the coating applicator on

your system.

Fluid Pressure 69 to 414 kPa (10 to 60 psi)

Recommended pressure depends on

fluid being dispensed and coating

applicator being used. Refer to the

Installation and Operations manual

applicable to the coating applicator on

your system.

Conveyor Air Regulator and

Gauge

276 kPa (40 psi)

The Conveyor Air Regulator and Gauge

is used to adjust pressure for the

conveyor stop pins and board pins.

 NOTE Some coating applicators need a minimum of 345 to 414 kPa (50-60 psi) for optimum

performance.

5-8 Operation

5.10.1 Main Air Regulator and Gauge

The Main Air Inlet provides regulated air pressure to the coating system from your facility air source.

You can adjust the main air pressure with the Main Air Regulator. The recommended pressure from the

facility air supply to the coating system is 85 to 90 psi (586 to 620 kPa).

To adjust the main air pressure:

1. Verify that the facility air supply is connected to the Main Air Inlet.

2. Locate the Main Air Regulator at the rear of the coating system (Figure 5-4).

TIP For accurate pressure adjustment, lower the pressure below the desired level and then

increase to the desired pressure.

3. Rotate the Main Air Regulator counterclockwise until the Main Air Gauge registers 0 psi.

4. Rotate it clockwise until the Main Air Gauge registers 85 to 90 psi (586 to 620 kPa).

 If the Main Air Gauge fails to register pressure, verify that the coating system is

connected to the facility air source.

 If there is an air leak, identify the source, shut off the facility air, and fix the leak before

proceeding.

 NOTE The regulator assembly is equipped with a relief valve to protect the system components.

Increasing the pressure above 95 psi (655 kPa) may trigger the relief valve. If so, reduce

the air pressure below 95 psi.
