GLOSSARY OF TERMS GLOSSARY OF TERMS & MEASUREMENT CONVERSIONS
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.

OCP Oven Control Program. The software which controls the operation of the Vitronics Soltec Reflow
oven.
VCS Vitronics Control System Oven controller consisting of the card cage / backplate, a DI board,
and one or more A.I boards
Zone An area of a Vitronics-Soltec Reflow oven that is comprised of an upper and a lower cell within the
process tunnel. Usually referred to as a heat zone or cooling zone .

CONVEYOR OVERVIEW
CONVEYOR TYPES
This Section describes the five types of conveyor transport systems available on the Vitronics-Soltec Reflow
Ovens. They are:
1) Belt-Only Mesh Belt Conveyor System.
2) Rail-Only Edge Rail Conveyor System.
3) Combo Edge Rail and Belt Conveyor System
4) XCS Edge Rail System with Extruded Center Support
5) MBS Combination Edge Rail and Belt System with Metal Band Support
The Mesh Belt system is base standard conveyor on Vitronics-Soltec Reflow Ovens. The Rail-Only, Combo,
XCS, or MBS Conveyor Systems are offered on new ovens by special order.
BELT-ONLY MESH BELT CONVEYOR SYSTEM
The mesh belt conveyor system is used to process single sided surface mount printed circuit boards.
