XPM2 / XPM3 Technical Reference Manual Conveyor Systems
PURPOSE OF THIS MANUAL & WHO SHOULD USE IT
This manual is intended to meet the needs of service personnel responsible for the regular service of Vitronics-
Soltec Reflow Ovens. Vitronics-Soltec does not consider this manual a specification for Vitronics-Soltec products
or any components contained in those products and reserves the right to change information contained in this
manual without notification.
This manual is intended to be a reference. Some of the topics explain manufacturing and assembly methods and
practices; however, many topics deal with specific service information and methods. Hopefully, insight will be
provided about the various sub-systems of the electrical control system to allow quick identification of problems
and possible solutions.
IMPROPER SAFETY PRECAUTIONS OR UNSAFE WORK METHODS MAY RESULT IN SERIOUS INJURY!
ATTENTION
This Manual is NOT INTENDED as a substitute for proper technical training or educational
background in the various technologies used in reflow ovens.
This manual is for service of Vitronics-Soltec ovens by Trained Qualified Personnel. An appropriate
understanding and use of safety procedures when working on and around the oven is
NECESSARY.
Caution
The following conditions may be encountered when working on any reflow oven:
fi High Temperature areas (up to 350
o
C)
fi High Voltage areas (up to 480 VAC)
fi High Current areas (up to 200 Amps)
fi Moving Mechanical Parts and Systems
fi Heavy Components
fi Sensitive Electronic Components
Some people who might use this manual are:
Vitronics-Soltec service technicians
Customer service technicians
Customer facilities maintenance personnel

999 º C Indicates an open thermocouple or thermocouple connection.
Actuator Used to raise and lower the top section of the oven.
AI Analog Input board. One of the boards in the Oven internal control unit.
Antistatic Device to inhibit the generation and instantaneous dissipation of static electricity.
Control Ladder Oven electrical schematic which show the relationship of all electrical circuits the oven controller
and to each other.
DC Drive An electronic power amplifier used to control the speed of DC motors.
E-stop Emergency stop.
EPO_________ Emergency Power Off
Encoder The electronic mechanism that supplies feedback information to the oven controller on how fast
the conveyor system is moving.
ESD Electro Static Discharge.
FNPT Female National Pipe Thread.
GPM Gallons Per Minute.
Heat slinger A set of fan blades mounted on the shaft of every cell motor. The function of a heat slinger is to
push heated air away from the motor windings and thus prevent premature motor failure.
Heater panel A large aluminum sandwich panel on the face of each heater cell in the oven.
Heat sink A piece of metal generally used to dissipate heat from some device.
ICB Inter Cell Baffle. These are pieces of metal used to help increase zone definition within the Oven
process tunnel.
Interlocks Optional Switches used to ensure that the access panels are closed on the Oven.
Inverter Variable Frequency Drive used to control the speed of the convection fan motors in the Oven.
IR Infrared, refers to a component of the heat which is generated in an oven.
LED Light Emitting Diode.
DI Digital Input Board. One of the boards in the Oven internal control unit.

Onload The end of the oven onto which product is placed.
Phase One leg of three-phase power.
Plenum A large (or elongated) cavity or chamber, usually in ductwork.
Preheat t A thermal area inside a Vitronics-Soltec Reflow oven.
Recipe A part of the Vitronics-Soltec software in which heater temperatures and conveyor speed are set.
Reflow A thermal area inside a Vitronics-Soltec Reflow oven.
ROSCO Redundant Over-temperature Sensing and Control Option.
RTV Brand name for a silicone sealing agent used in the Reflow oven.
Set point A number used to define a particular parameter in the oven. For example, the temperatures that
are defined in a recipe are referred to as the heater set points for each heater.
Slot settings Air passages (slots) on both sides of the heater panel that can be adjusted from fully open to fully
closed. Slot settings refers to the actual opening size of these air passages.
