Introduction

I. How to Use this Manual

Congratulations on the purchase of your Asymtek oven. This equipment is designed to satisfy a

wide range of solder Cure and PCB curing applications. When properly used and maintained

within operating limits described throughout this manual the machine will provide years of trouble

free service.

This manual is applicable to all Asymtek oven models TCM-2200, TCM-3300 and TCM-4600

running WINDOWS-XP based software. It contains installation, operation, troubleshooting and

maintenance procedures for electrical and mechanical systems on all models, including most of

the common optional equipment available for the ovens. Electrical schematics, nitrogen plumbing

diagrams and additional information may be found at the back of this manual and/or OEM

instruction manuals.

CAUTION: Although most installation and service

routines can be performed easily, extreme caution

should be exercised when working with live electrical

circuits. ONLY a trained electrical technician or

engineer following all required codes and

lockout/tagout procedures should perform this work.

The first section of the manual describes for the technician the requirements and necessary steps

to uncrate and install the oven.

For a detailed explanation of software operation, please refer to the section entitled “Operating

System Software Guide”.

The section entitled “Standard and Optional Equipment Operating Guide” explains each of the

features and available standard options. It includes operating instructions as well as schematics

and diagrams.

To use the troubleshooting guide, please refer to the contents to select the troubleshooting

section most applicable to the symptoms exhibited by the machine. It is recommended that the

technician read the entire applicable section first before starting the troubleshooting procedure.

Once he is familiar with all the required tests, he may then decide upon the most logical

troubleshooting steps to take. The troubleshooting section contains a page useful for determining

computer channel assignments for the various heating zones as well as a guide for determining

which SSR (Solid State Relay) is controlling a particular zone. It also includes a section that will

instruct the technician as to which covers will need to be removed to access internal components.

The technician should refer to the final section of the manual for any maintenance procedures

that need to be performed.

If any further assistance should be required, contact Asymtek Technical Support Group;

To perform the procedures presented in this manual you may need the following equipment:

•Medium and large Phillips head screwdrivers

•Large, medium and small flat blade screwdrivers

•Set of Allen (hex) keys: Metric (1.5mm to 10mm)

•Set of open end wrenches or socket set: Metric (9mm to 20mm)

•Channel-lock pliers or pipe wrench with 3”(75mm) capacity

•Wire cutters (diagonal cutters)

•Needle-nose pliers

•Wire strippers

•Terminal crimpers with assorted terminals

•Multimeter (voltmeter/ohmmeter)

II. Safety Precautions

II.1. Overview

This chapter provides safety guidelines that should be followed when operating the Cure Oven

System. These guidelines ensure personal safety and protect equipment during installation,

operation, maintenance, troubleshooting, and other potentially dangerous procedures. Safety

training is available upon request.

Facility

Installation The oven should be uncrated and installed using an appropriate forklift and

following the procedures as outlined. Failure to use appropriate equipment

may result in personal injury and/or property damage.

The oven should be connected to power by a qualified electrician and must

comply with all appropriate electrical and safety codes. See instruction

manual Section III in Facility Installation for power supply requirements.

Failure to follow electrical codes or the use of under-rated supply

conductors may cause property damage and may subject the operator to

hazardous voltages.

The exhaust ducting for the oven should be designed and installed by a

qualified HVAC technician capable of calculating air flow from suction

blowers and flow losses in upstream and downstream ducting. Improper

exhausting may allow flux fumes to be inhaled by the operator.

Special Precautions should be taken if the unit is installed in a sprinklered

room or building. Refer Sprinkler System in Facility Installation, Section XI.

Ensure packing material is removed.

Read instruction manual.

Refer Leveling of the oven in Facility Installation, Section VII.

Operating the

Equipment When oven is in use, the edge hold conveyor system and other machine

components will become hot. Please observe all hot surface warning

placards applied to the machine. Please also observe all other warning

placards and instructions. Do not open the oven while it is in operation.

This will expose the operator to high temperature air.

Power Hood Lifts When closing the top shell of the oven, be aware that long hair or loose

fitting clothing may become entangled in the system. The shell may also

pose a crushing threat to bodily extremities.

Software

Operation Do not alter settings in the system software beyond that which is described

in this manual without first contacting the factory. Doing so may affect safe

operation of the machine.

Nitrogen

Operation Even though nitrogen is an inert substance, a few simple precautions

should be made. Proper ventilation in the area where the system is being

used must be maintained to keep the oxygen level in the air at safe levels.

Otherwise the continuous flow of nitrogen can displace the air and deplete

the normal oxygen level. Create sufficient ventilation in the area of the

Cure oven to exhaust the excessive nitrogen laden air and replace it with

normal atmosphere. Installation of a room oxygen monitoring system is

recommended especially if the oven is installed in a small-enclosed area.

Edge Hold/Mesh

Belt Operation

Caution must be exercised when working near the belt or conveyor

systems. Do not operate the system with guards removed and be aware of

all pinch point warning decals. Also, be aware that long hair or loose fitting

clothing may become entangled in the system. Should this occur, an

EMERGENCY STOP button is located at each end of the oven. Pressing

this button will immediately stop the conveyor system.

Troubleshooting

and Maintenance Please be aware that although many service routines can be performed

easily, extreme caution should be exercised when working with live

electrical circuits. ONLY a trained electrical technician or engineer should

perform this work. Before removing any panels, all power to the oven

should be switched off and the temperature should be at room ambient.

While system components are fully tested and rated for long life, it is the responsibility of

the customer to properly maintain the equipment after the warranty period to ensure the safety

and functionality of the machine. Improper maintenance and checking can result in system or

subsystem failures that are not the responsibility of the manufacturer. This includes the cleaning

of the various areas, the tightening of screws, the confirmation of proper voltage and current

draws, appropriate lubrication, proper exhaust, proper handling during movement of the machine,

and periodic checks of each of the subsystems for functionality.

II.2. Cautions and Warnings

Three basic types of alert boxes are used in this manual to warn personnel during operation,

maintenance, and troubleshooting of the Cure Oven System:

DANGER! means the action will cause serious injury or death to

personnel if proper procedures are not followed.

WARNING! means the action may result in serious injury or death if

proper procedures are not followed.

CAUTION! means the action may cause damage to equipment and/or

minor to moderate injury to personnel if proper procedures are not

followed.

II.3. Cure Oven System Safety Labels

Safety labels affixed to system hardware are used to make personnel aware of potential hazards

and remind them to take necessary safety precautions. Table II-1 describes them in detail.

Table II-1 Safety Hazard Labels

Label Part Number Description

2545 Hazardous Voltage Warning - Warns

personnel of areas where high voltage is

present which may cause severe injury

or death.

3628 Hot Surface Warning - Warns personnel of

hot surfaces that may cause burns if touched.

3627 Moving Parts Warning - Warns personnel to

keep hands and fingers away from

mechanisms that could cause injury.
