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.
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.
MNPT Male National Pipe Thread.
Offload The end of the oven where product exits the tunnel.
Ohmmeter A precision instrument used to check and display the value of electrical resistances in Ohms.
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.
SSR Solid State Relay
T/C ThermoCouple
OCP Oven Control Program. The software which controls the operation of the Vitronics Soltec Reflow
oven.
VCS Vitronics Soltec 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”.
