generator. The tach. generator is a DC voltage generator which supplies a voltage to

 

the DC motor control board and is used as a reference for maintaining a constant

 

conveyor speed.

NOTE

The 1200 Series Ovens utilize 2 complete conveyor drive systems.

TIME TEMP DISPLAY

The Time/Temp. Display is energized when the Fan Switch is closed, supplying120

 

VAC to the primary of the 12.6 volt Transformer The secondary output of the

 

transformer, normally 13 to 14 VAC (depending on input), with a center tap is

 

supplied at terminals 1,2, and 3 of the Time/Temp. Display. The center tap is

 

terminal 2. The display works on a balanced input and center tap voltage to each leg

 

must be 1/2 the total reading.

 

The speed side of the Time/Temp. Display uses a slotted disc (cemented to tach.

 

coupling) to break the infra-red light beam of the optical switch (mounted on gear

 

motor) producing electrical pulses that are transmitted to the display. The display

 

converts these pulses into a read-out of minutes and seconds. The temperature

 

portion of the display uses a Thermistor Probe to sense oven temperature. The

 

thermistor outputs a resistance proportional to the oven temperature. This resistance

 

is then converted by the display into a temperature reading.

 

NOTE: The 1200 Series Ovens use a Double Pole Double Throw Switch to connect

 

the two Optical Encoder Assemblies to the Time/Temp Display. By activating the

 

switch, either the front or rear belt speed can be shown by the Time/Temp Display.

POWER SUPPLY

 

Electrical Power to be supplied to the Oven by a five conductor service. Voltage from

 

 

the black conductor to the white conductor is 120 VAC.

 

 

Black conductor is Hot

 

 

Red conductor is Hot

 

 

Orange conductor is Hot

 

 

White conductor is Dedicated Neutral

 

 

Green conductor is Ground

 

 

 

MAIN FAN CIRCUIT

 

Electrical power is permanently supplied through 6, 50A fuses to the normally open

 

 

contacts of the Mercury Contactors. Power is also supplied through 2, 15A fuses to

 

 

the normally open contacts of the Double Pole Main Fan Relay, the Double Pole

 

 

Main Fan Switch, and the normally open Cool-Down Thermostat (thermostat closes

 

 

at 160°F and opens at 140°F.) Closing the Main Fan Switch energizes the coil of the

 

 

Main Fan Relay. The normally open contacts now close, energizing the Main Fan

 

 

Motor, and the Control Box Cooling Fan. Closing the Fan Switch also supplies power

 

 

to the Hour Meter (hour meter discontinued after S/N 3484), the 12.6 VAC

 

 

Transformer, the Heat and Conveyor Switches.

TRANSFORMER (12.6

 

Upon closure of the Fan Switch, 120 VAC is supplied to the primary of the 12.6 VAC

VAC)

 

Transformer. The Transformer steps the voltage down to 12.6 VAC (normally 13 to

 

 

14 VAC) with a center tap, and supplies power to the Time/Temp Display. The

 

 

voltage from each leg of the Transformer©s secondary to the center tap should be

 

 

one half of the secondary voltage.

HEAT CIRCUIT

 

Closing the Fan Switch and the normally open Heat Switch supplies 120 VAC

 

 

through the Air Pressure Switch and the normally closed Hi-Limit Thermostat

 

 

(manually re-settable, opens at 190°F) the 3A Fuse, to the L1 terminal of the

 

 

Temperature Control Board, the coils of the Mercury Contactors, and to the Heat

 

 

Indicator Light.

TEMPERATURE

 

When the Heat Switch is closed, 120 VAC is supplied to the Temperature Control.

CONTROL

 

The Temperature Control Potentiometer (2.5K ohm) is adjusted to desired

 

 

temperature. The Thermocouple will provide varying millivolts to the Temperature

 

 

Controller. The Temperature Controller switches the L2 line of the Contactor coils at

 

 

intermittent intervals to maintain desired temperature.
