TABLE OF CONTENTS 7 Warning & Safety Information..................................................................................................... 2 Warranty ....................................................................................................................................... 4 General ......................................................................................................................................... 6 Oven Theory of Operation ......................................
1. 2. 3. 4. 5. ELECTRIC OVEN THEORY OF OPERATION When the Main Switch (S1) is turned on; The Oven Fan Motor (M1) located in the Back Wall will run. The Fans (M3) located on the Control Panel will run. The Temperature Control (TC) should display both the actual and set-point temperatures. The Conveyor Control (CC) should display the belt time. The conveyor belt should move.
ELECTRIC OVEN THEORY OF OPERATION 9 C1 & C2 - A contactor is an electrically controlled switch used for switching a power circuit. A contactor is controlled by a control circuit that has a much lower power level than the switched circuit. They consist of a small coil and a set of three SPST contacts. When S2 & S3 are closed, line voltage is applied to the coil, which closes the contacts. Then power is allowed to flow to the SSR’s.
ELECTRIC OVEN THEORY OF OPERATION has an internal centrifugal switch (S2). The motor is dual voltage and reversible. The voltage to power the motor comes from the Cool Down Timer (R1), and the motor will continue to operate for approximately 30 minutes after the main switch is turned off. There are no user serviceable parts in the motor, and the bearings are permanently lubricated. M2 - The conveyor motor (M2) is a brushless 24 VDC gear motor.
ELECTRIC OVEN THEORY OF OPERATION 11 relay is a safety feature to allow the oven to cool down to room temperature, and to eliminate heat stress on the components of the oven. S1 - The Main Switch is a SPST normally open switch, mounted on the front of the Control Box. Activating this switch applies voltage to Terminal T6 of the Cool-Down Timer (R1). When used with the optional AVI Hood System, a remote switch mounted in the front of the AVI Hood replaces it.
HOOD THEORY OF OPERATION When any one of, or all of, the Hood Operator Switches (S2, S3, & S4) are turned on; 1. The Exhaust Fan Motor (M1) located on the roof will run. 2. The Variable Frequency Drive (VFD) will display a set value. The values are preset from the factory and can be referenced in the I&O manual. 3. The ovens associated with the corresponding switches will turn on.
HOOD THEORY OF OPERATION 13 CB - Circuit Breakers are used to protect electrical components. If a CB is tripped, eliminate the cause and press the front to reset. CS - The Current Sensor is a device that detects electrical current in a wire, and then generates a signal proportional to it. It drives an LED indicator lamp (L3) to indicate that the VFD is drawing current and operating. A minimum of 1.5 AAC is required.
HOOD THEORY OF OPERATION S2, 3, & 4 - These DPST (NO) switches are located on the front of the hood and control the ovens, as well as initiating and sequencing the operation of the VFD and damper circuits. Line voltage is continuously applied to pin 1 of REC 4, 5, & 6, which is connected by a wire to a contact in S2, 3, & 4. This is shown on the schematic as the lower RH connection point of S2, 3, & 4.
OVEN TROUBLESHOOTING 15 Mechanical Function If your oven does not function properly, please verify the following conditions: 1. Verify that the power cord to the oven is connected and/or plugged in if equipped with a plug and receptacle. 2. Check to see that the circuit breakers in the building electrical service panel have not been tripped or turned off. 3. Check all circuit breakers on the oven control panel to ensure they have not been tripped. 4. Ensure proper voltage, amperage, and wire size.
HOOD TROUBLESHOOTING Before troubleshooting the hood: 1. Make sure that the RUN lamp and POWER lamp are lit. 2. Check to see that the breaker in the service panel is not tripped. 3. Check to see that the breaker on the hood electrical box is not tripped. 4. Make sure the Switch Relocation Cords (SRC) are properly installed to the oven(s). 5. Check to see that the grease filters are clean & installed properly. 6. Check to see if the exhaust fan is rotating in the correct rotation.

OVEN SERVICE PROCEDURES Conveyor Control Programming Procedure Read the entire instruction before programming. Configuration Key Functions = Behind the in XLT is a hidden button. This is used along with the up and down button to access the programming mode. Use this after each step to advance to the next parameter when programming. UP = Increases the setting of the selected parameter. Down = Decrease the setting of the selected parameter. 1.
OVEN SERVICE PROCEDURES Temperature Control Programming Procedure Read the entire instruction before programming. Configuration Key Functions = The new setting of the selected parameter is stored and the display advances to the next parameter. This is required between each parameter. = Increases the setting of the selected parameter. = Decrease the setting of the selected parameter. 1. Open V101 switch for Basic Configuration (Figure 1) 2.
HOOD SERVICE PROCEDURES Hitachi X200 Restoring Factory Defaults Access program parameters by pressing the key one time and using the up and down arrow keys to navigate to the appropriate parameter press the key again to make adjustments to that parameter by using the up and down arrows. To store the new settings press the button one time. B031 = 01 B084 = 01 After pressing the key Press and hold the down arrow key and key all at the same time.
