1.12.1.1 Front Panel
Below are descriptions of SL-940E/SL-941E front panel buttons as shown in Figure 1-4.
NOTE Refer to Section 5 - Operation for detailed descriptions of all front panel buttons and
functions.
Item Name Description
1 Start Button
The Start button is a push button located on the front panel. It turns on the
power to the coating system. The Start button glows green when pushed,
and continues to glow until the Stop button or Emergency Machine Off
(EMO) button is pressed.
2
Grounding Strap
Connector
Grounding straps worn by the operator or technician attach to this
connector. This prevents electrostatic discharge (ESD) damage to
workpieces and conformal coating system electronics during coating
operations and servicing.
3 Stop Button
The Stop button is a push button located on the front panel. When pushed,
it stops all power to the conformal coating system, with the exception of the
laptop computer.
4 Applicator ON/OFF
Press Applicator ON/OFF to turn the coating applicator on and off. This
feature can be used to test run a program without dispensing fluid (dry
mode).
5
Emergency Machine
Off (EMO)
Activating the EMO (E-Stop) vents all pressure in the pneumatic system,
de-energizes the robot motors, and cuts power to all system components
except the laptop computer. An EMO button is located on the front and rear
of the conformal coating system. Refer to Section 2 - Safety for additional
information.

Item Name Description
1 Robot
The Robot moves in the XYZ planes. It is controlled through the coating
system software. The coating applicator, camera, laser pointer
programming tool, and board present sensor are mounted on the robot

Conformal Coating
Applicator
(SC-400 shown)
Depending upon your application requirements, the Select Coat SL-
940E/SL-941E Series Conformal Coating System can be configured with
any of the conformal coating applicators listed in Table 1-1.

Tooling Rails
(SL-941E)
The Tooling Rails are standard on the SL-941E and secure the workpiece
for batch system operations.

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.
