SEQUENCE OF OPERATION

IMPINGER ADVANTAGE

SERIAL NUMBER N28654 AND ABOVE (OVENS WITH PUSH BUTTON CONTROLS)

MODEL 1454

220/380VAC

50 HZ.

3 PHASE

MODEL 1455

240/415VAC

50 HZ.

3 PHASE

 

 

POWER SUPPLY

Electrical power is to be supplied to the oven by a five conductor

 

service.

 

 

 

Brown conductor is hot.

 

 

Black conductor is hot.

 

 

Black conductor is hot.

 

 

Blue conductor is neutral.

 

 

Green conductor is ground.

 

CONTROL BOX AUTO

When the temperature in the control box reaches 120°F ± 3°F (48.9°C

COOL DOWN

± °

 

 

 

1.7 C), the cooling fan thermostat will switch power to the control

 

box cooling fan. The thermostat will interrupt power to the cooling fan

 

when the control box temperature falls to 100°F ± 3°F (37°C ± 1.7°C).

MAIN FAN CIRCUIT

Electrical power is permanently supplied through three 50 A fuses to

 

the normally open contacts of the heat relay. Power is also supplied,

 

through the 10 Amp motor and control fuse, through the normally

 

closed control box hi-limit thermostat, to the normally open oven power

 

switch. Power is also supplied to the control box cooling fan

 

thermostat. Closing the oven power switch supplies line voltage to the

 

main fan motor. Closing the oven power switch also supplies line

 

voltage to the heat circuit and to the primary of the oven control

 

transformer.

 

 

HEAT CIRCUIT

Closing the oven power switch supplies line voltage through the main

 

fan air pressure switch, through the normally closed oven cavity hi-limit

 

thermostat, to the oven control

 

TEMPERATURE CONTROL

Closing the oven power switch supplies line voltage to the primary of

 

the control transformer and through the air pressure switch and oven

 

cavity hi-limit, to the oven control. Secondary voltage, 24VAC, is

 

supplied to the oven control. The oven control is set to desired

 

temperature. The thermocouple will provide varying millivolts to the

 

oven control. The oven control supplies line voltage to the heat

 

contactor at intermittent intervals to maintain desired temperature. The

 

display on the oven control will indicate when the heat contactor is

 

energized.

 

 

 

NOTE: The display also indicates oven temperature.

CONVEYOR DRIVE

Closing the oven power switch supplies line voltage to the conveyor

 

motor and to the primary of the control transformer. Secondary

 

voltage, 24VAC, is supplied to the oven control. Setting the oven

 

control to the desired time outputs voltage, through a reversing switch,

 

to the conveyor motor.

 

 

NOTE: The conveyor system uses a hall effect sensor and magnet to

 

prove operation of the conveyor motor. If the motor is not running,

 

“BELT JAM” is indicated on the display.
