1.12.1.3 Conveyor
Below are functional descriptions of SL-940E components shown in Figure 1-6.
Item Name Description
1 Solvent Cups
The SL-940E conveyorized system has two 125 ml stainless steel cups that
are installed on separate brackets mounted to the front conveyor rail. One
cup holds solvent for cleaning the dispensing needle. A second cup is used
for the purging of conformal coating fluid.
2 Chain Conveyor
A chain conveyor is standard on the SL-940E Conformal Coating System.
All conveyors are SMEMA-compatible. The conveyor is controlled through
the ECXP software.
3 Board Sensor
Mounted on the conveyor rail within the dispense zone, the Board Sensor
detects the presence of a workpiece entering the system. The signal is sent
to the conveyor controller, which halts conveyor motion and lowers stop
pins to hold the part in place for dispensing.
4 Stop Pin
The Stop Pin is a pneumatic device used to stop workpieces as they are
conveyed into the system.
5
Manual Width
Adjustment
The Manual Width Adjustment allows you to adjust the distance between
the conveyor rails.
6 Board Pins
Pneumatically actuated Board Pins lower into holes in the board to secure it
precisely in place for accurate fluid dispensing.

1.12.1.4 Front Cabinet
Below are functional descriptions of SL-940E/SL-941E Series Conformal Coating System components
shown in Figure 1-7.
Item Name Description
1
Reservoir Pressure
Gauge
The Reservoir Pressure Gauge displays the air pressure supplied to the
fluid reservoir and solvent reservoir.
2
Reservoir Pressure
Regulator
The Reservoir Pressure Regulator controls the air supplied to the fluid
reservoir and solvent reservoir.
3
Laser Fan Width
Control Amplifier
(optional)
Laser Fan Width Control provides closed-loop control of the conformal
coating process, automatically compensating for variables within the
process environment that can affect fluid fan width.
4 USB Hub
The USB Hub distributes USB information from the computer to the Main
PWA, Conveyor PWA, and other components.
5
Computer Power
Supply
The Computer Power Supply supplies power to the laptop computer.
6 Spill Pan
The spill protects the dispensing system from fluid spills and overspray. The
pan is removable for ease of cleaning and is interlocked for safety.
