OVEN THEORY OF OPERATION
M2 - The Conveyor Motor is a brushless 24 VDC gear motor. The motor receives current from the
OMC through three (3) wires; 1) A black or “W” phase, 2) a white or “V” phase, and 3) a red or
“U” phase. They carry between 18 to 24 VDC. Each wire is energized by the OMC in sequence to
provide power to the individual stator coils which, in turn, provide motor rotation. To determine
the rotor position and send this position to the controller, three (3) Hall Effect switches are utilized.
They read the rotational information from a disc mounted on the rotor assembly. This information
is transmitted to the OMC by three (3) wires; 1) an orange “U” phase pole signal output, 2) a green
“V” phase pole signal output, and 3) a green/white “W” phase pole signal output. These are locat-
ed in a plug that inserts into the OMC1 or OMC2. There are two (2) additional wires in this plug;
1) a purple wire which is voltage for the pole sensor, and 2) a gray wire that is ground. The OMC,
using an internal logic circuit, energizes the stator coils to provide proper rotation and sets the en-
ergization (phase) timing to obtain the desired belt speed set on the controller. The motor drives an
integral gear box that reduces the motor output speed to give the correct travel time to the convey-
or belt. The integral gear box is sealed and permanently lubricated with grease. The ratio is 200:1.
This motor contains no serviceable parts. The OMC will detect if the conveyor belt has a jam by
monitoring the rotor signal. If the signal falls more than 25% below the expected rate a jam is de-
tected. This action will stop the conveyor and display an alarm on the LUI. To reset the alarm
press and hold the TIME key for ten (10) seconds.
M3 - The Flow Path Pressure Generating fan supplies combustion air for the Burner. It is con-
trolled by turning on and off the main power button. A filter is provided to ensure clean air. There
are no user serviceable parts in the motor, and the bearings are permanently lubricated.
OMC - The Oven Machine Control reads selections or parameters from the LUI. It holds the logic
for the conveyor controls and the temperature controls. The OMC will turn on or off the gas valve
(V2), start and stop M1, send the call for heat signal, read the thermocouple and monitor the cur-
rent sensor.
