OVEN THEORY OF OPERATION 11
FLT 1 - Is an inline filter used in world ovens. The filter is placed in series with the Line voltage
being supplied to the oven. The filter is used to reduce Electromagnetic Interference created by our
equipment and back-feeding it into other appliances. EMI filters use capacitors to inhibit direct
current while permitting alternating current. EMI filters also use inductors which redirect high
voltages and high frequencies by dissipating them to ground.
Hl-H6 - The Heating Elements convert electricity into heat through the process of joule heating.
Electric current through the element encounters resistance, resulting in heating the element. The
resistance values of the four (4) different part numbers used are:
• XP-5201-208-4.5 4500 Watt 9.61 Ohms
• XP-5201-240-4.5 4500 Watt 12.80 Ohms
• XP-5202-208-5.3 5300 Watt
• XP-5202-240-5.3 5300 Watt
8.16 Ohms
10.87 Ohms
Please refer to the Parts section for the proper application.
LR- The Line Reactor is used in all world ovens. It is an inductor wire between the incoming AC
power source and the VFD. It is used to filter out spikes of current and reduce harmonics.

LUI - The Large User Interface is powered by the OMC by the RS 485 cable. The main power
button is located on the front face of the LUI. The conveyor(s) and temperature of the oven is con­
trolled through the LUI. You can change the factory settings for the oven size, VFD/No VFD, cool
down mode, and Gas/Electric, etc. For a Standard Oven it will also display the main fan amps. The
LUI will display error messages and maintenance alarms. There are 12 menu presets for predeter­
mined time and temperature settings. The screen can be locked to prevent unwanted mischief.
Ml - The Main Motor for standard ovens is a PSC, single phase, capacitor run motor and has an
internal S2. The motor is dual voltage and reversible. The voltage to power the motor comes from
the RI terminal #2. For world ovens Ml is a 3 phase inverter rated motor with an internal S2. It
gets power from a variable frequency drive which is then turned on by the OMC. The main motor
will continue to operate for approximately 30 minutes or until the oven temperature is less than
225 degrees Fahrenheit after the oven is turned off There are no user serviceable parts in the mo­
tor, and the bearings are permanently lubricated.
