1 Introduction

1.1 Overview

The Select Coat

SL-940E/SL-941E Series Conformal Coating Systems are designed to provide the

highest quality and productivity for automated coating processes. This manual is intended primarily as a

reference for production operators, process engineers, and service technicians. However, others

unfamiliar with Asymtek products may also find this manual useful as a general introduction to the

system. This section covers the following topics:

• Manuals Supplied

• Training

• Standard Equipment

• Optional Equipment

• Conformal Coating Applicators

• System Features

1.2 System Description

The SL-940E/SL-941E systems provide consistent, uniform dispensing of a variety of conformal coating

materials for both conveyorized (SL-940E) and batch (SL-941E) coating applications. These coating

systems are high-speed, high-accuracy conformal coating systems with integrated, closed-loop process

control that ensures superior coating quality. Process parameters are recorded and traceable through Easy

Coat

(ECXP) software running on Windows

XP operating system. The system can eliminate the

requirement for labor-intensive board masking, providing accurately controlled patterns, film builds, and

production flexibility in an automated process. Film thickness is achieved in a single pass with little or no

masking and with virtually no overspray.

1.3 Safety First

Operation of your SL-940E/SL-941E involves heat, air pressure, pneumatic devices, electrical power,

mechanical devices, and the use of hazardous materials. Read this manual in its entirety before attempting

any system or component operation. It is essential for all personnel working on or around the coating

system to fully understand the hazards, risks, and safety precautions associated with operating the system.

When properly operated and maintained, the coating system is safe and reliable. Refer to Section 2 -

Safety for additional information.

WARNING! CAUTION!

Consult the Material Safety Data Sheet (MSDS) for all fluids used with the

coating system. The MSDS provides material usage instructions, disposal

instructions, and safety precautions.

1.4 Facility Requirements

To ensure optimal performance and safety, it is necessary to install the coating system and its components

in a facility that meets the requirements listed in Section 10 - Specifications. If you have any questions

about facility requirements, please contact Asymtek Technical Support.

1-2 Introduction

1.5 Manuals Supplied

Your SL-940E/SL-941E arrives with manuals for installation and operation of major system components

and software. For some system components, you may receive Original Equipment Manufacturer (OEM)

manuals. Generally, these OEM manuals are only needed for reference and advanced troubleshooting.

Consult only Asymtek manuals, unless directed to do otherwise by Asymtek Technical Support or

Asymtek documentation. For the convenience of Asymtek customers, manuals may be downloaded from:

http://www.asymtek.com/support/manuals.htm

Below is a sample list of manuals that may be shipped with the SL-940E/SL-941E Series Conformal

Coating System. Optional manuals listed may or may not be included, depending on your system’s

configuration.

• Select Coat SL-940E/SL-941E Series Installation, Operations, and Maintenance Manual

• Select Coat SL-940E/SL-941E Series Quick Operations Manual

• Fluid Applicator Manual (specific to your application)

• Easy Coat for Windows XP User Guide (P/N 7210920)

Optional:

• Laser Fan Width Control Owner’s Manual (P/N 7201445)

• Viscosity Control System Owner’s Manual (P/N 7204869)

• Flow Monitoring System Installation, Operations, and Maintenance Manual

• Original Equipment Manufacturer Manuals (as applicable)

1.6 Training

Asymtek offers quality training for our dispensing platforms, valves, software, and applications both on

and off-site. The labs at our Carlsbad, California, USA corporate location are dedicated to providing a

specialized course of instruction for our customer's specific needs. With the assortment of tools available

in our labs, we are able to provide a better learning experience overall. Students will rebuild machine

subassemblies, troubleshoot real problems, and learn a variety of setup techniques. In addition, your

machine's operability and production are not disturbed due to class usage.

1.6.1 Student Certification

Upon successful completion of the training course, the student is issued a Certificate of Completion.

1.6.2 Student Registration

Students can register for training at the Asymtek website www. asymtek.com/support/training or call

1-800-ASYMTEK to request information or to register for training. .

1.7 Supported Coating Materials

The SL-940E/SL-941E was designed for dispensing the following materials. Contact Asymtek for

materials not listed.

 Epoxy  Silicone

 Acrylics  Urethane

 NOTE Asymtek does not supply conformal coating materials. Consult the manufacturers

Material Safety Data Sheet (MSDS) for all fluids used with the coating system. The

MSDS provides material usage instructions, disposal instructions, and safety precautions.

1.8 Standard Equipment

1.8.1 Computer System

The computer system consists of a laptop computer. The computer arm is adjustable in height and

right/left orientation.

1.8.2 Easy Coat for Windows XP Software

Easy Coat for Windows XP (ECXP) is Asymtek proprietary software for use in a Windows XP

environment, developed specifically for conformal coating applications. ECXP controls both the

dispensing head (robot) movements and the dispensing operation. ECXP features include:

• Off-Line Programming

• Multiple Application Tool Selection

• Software controlled fluid and air pressure

• Process history logging

1.8.3 Chain Conveyor (SL-940E)

The chain conveyor transports the workpiece into and out of the coating system. Operation of the

conveyor is automatic during production runs. The conveyor features two board pinning clamps that

locate the workpiece in terms of X/Y location and rotation. The system can be configured with an

optional pre-queue board station which allows simultaneous moving of workpieces in and out of the work

area. See Figure 1-6.

1.8.4 Light Beacon

The Light Beacon is a device that displays system status and is located at the top right corner of the

system. It has four different colored lights that can be constantly ON or flashing and has an audible alarm.

Refer to 2.14. Light Beacon for an explanation of each color indication.

1.8.5 Safety Interlock

An interlock sensor detects if the dispensing area hood is open or closed. If the dispensing area hood is

opened when a program is running, all dispensing motion stops to protect the operator from injury. A

second interlock sensor is located behind the spill pan to ensure an appropriate ventilation path when the

drawer is pulled out for maintenance.

1.8.6 Low Air Pressure Sensor

The Low Air Pressure Sensor is connected to the Main Air Inlet. If the pressure drops below a set point, it

triggers the coating system safety interlock. This feature is used to alert the operator of pressure drop

conditions that may occur in large facilities with a number of pneumatic devices.

1.8.7 Solvent Cups

The SL-940E/SL-941E 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.
