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.
