OVEN THEORY OF OPERATION
PS - The Power Supply rectifies line voltage to 24 VDC, and supplies power to the OMC, IC, FS,
and S2. A four (4) amp fuse is used to provide over current protection, which is mounted on the
PS itself. There are no other fuses used anywhere else.
PU - The Pick-Up is physically mounted within M2 and utilizes hall effect technology integral to
the M2 to monitor the rotation speed. The hall effect signal is transmitted to the OMC, which con-
verts it into linear travel speed of the conveyor.
R1 - The Oven Fan Motor Relay is used as a remote switch to handle the higher amp load of
M1. Is a Single Pole Double Throw (SPDT) relay, which is an electrically operated switch. It uses
an electromagnet to operate a switching mechanism.
RTD - The Resistive Thermocouple Detector monitors the air temperature inside the bake cham-
ber. The RTD wire is a pure material, typically platinum, nickel, or copper. The material has an
accurate resistance/temperature relationship which is used to provide an indication of temperature.
S2 - The Centrifugal Switch is a SPDT switch physically mounted inside M1. When M1 comes up
to full speed, S2 closes and sends a 24 VDC signal to the IC. It functions as a safety feature to pre-
vent burner operation if the M1 fails to rotate.
S3 - Standard Ovens - The High Limit Switch for standard ovens is a bi-metal, normally closed
(NC), Single Pole Single Throw (SPST), switch physically mounted in the side panel of the Bake
Chamber. Its purpose is to provide fail safe operation. If the temperature of S3 exceeds
600°F/316°C it opens and interrupts line voltage to all components.
