POWER SUPPLY

Electrical power is supplied to the oven by either a single phase, 3 conductor service, or three phase, 4 conductor service.

Single:

Black conductor is hot. White conductor is hot. The green conductor is ground.

Three Phase:

Black conductor is hot. Red conductor is hot. Orange conductor is hot. The green conductor is ground.

FAN CIRCUIT

Electrical power is permanently supplied to the normally open contacts of the main power relay, the main switch 1 A fuse, terminal 1 of the time delay unit, also through the normally closed hi limit thermostat, to the main power switch. Closing the main switch enables the 30 minute timer delay relay. The time delay relay supplies line voltage to the cooling fan motor.

INFRARED HEAT

Closing the main switch supplies line voltage to the coil of the main power relay, closing the contacts to feed the normally open solid state relays for the top and bottom heaters. Power also feeds the primary of the transformer, secondary 16V feeds through a circuit breaker to the control unit. The control energizes the solid state relays for the top and bottom heaters feeding voltage to the heating elements.

TEMPERATRE CONTROL Closing the main switch supplies line voltage to the primary of the control

transformer, secondary 16vac is supplied to the control unit which is set to a desired temperature. The thermocouple will provide varying millivolts to the control unit. The control unit supplies voltage to the coil of the heater relays at intermittent intervals, to maintain a desired temperature. The display on the control unit will signal when the main heater relay is energized. NOTE: The control unit will also display oven temperature.

CONVEYOR DRIVE

Closing the main switch supplies line voltage to the primary of the control transformer, secondary 16vac is supplied to the control unit. Setting the control unit to the desired time, outputs voltages to the conveyor motor.

AUTOMATIC COOL DOWN

When the machine is started, the time delay unit is energized, permitting the main fan to operate for approximately 30 minutes after the machine is shut off, to cool the machine. When the machine is turned off the time delay unit keeps the main fan energized, maintaining operation of the fan for 30 minutes.

Electrical power is supplied to the oven by a three phase, 5 conductor service. Black conductor is hot. Red conductor is hot. Orange conductor is hot. White conductor is neutral. The green conductor is ground.

Electrical power is permanently supplied to the normally open contacts of the main power relay, through a set of noise suppressers, through an EMI filter, through a 1 A fuse, through the normally closed hi limit thermostat, to the main power switch.
