1 PHASE 1131-080-A1 120/240VAC 60 HZ. 1 PHASE 1131-08H-A 240 VAC 60 HZ. 1 PHASE 1132-080-A 120/208VAC 60 HZ. 3 PHASE 1132-080-A1 120/208VAC 60 HZ. 3 PHASE 1132-08H-A 208 VAC 60 HZ. 3 PHASE 1133-080-A 120/240VAC 60 HZ. 3 PHASE 1133-080-A1 120/240VAC 60 HZ. 3 PHASE 1133-08H-A 240 VAC 60 HZ. 3 PHASE 1161-080-A 120/240VAC 60 HZ. 1 PHASE 1162-080-A 120/208VAC 60 HZ. 3 PHASE POWER SUPPLY Electrical power to be supplied to the oven by a three conductor service for single phase and a four conductor service for three phase. Black conductor is hot. Red conductor is hot. Orange conductor is hot (used for three phase only). White conductor is neutral. Green conductor is ground. CONTROL BOX AUTO When the temperature in the control box reaches 120°F ± 3° (48.9°C ± 1.7°), theCOOL DOWN cooling fan thermostat will switch power to the control box cooling fans. The thermostat will interrupt power to the cooling fans when the control box temperature falls to 100°F ± 3° (37.8°C ± 1.7°). MAIN FAN CIRCUIT Power is permanently supplied through the 10 amp fuses, through the normally closed oven cavity hi-limit thermostat, to the normally open main power switch. Power is also supplied to the normally open cooling fan thermostat. Closing the main power switch energizes the coil of the oven start relay, it’s contacts close enabling the 20 minute time delay relay. The 20 minute time delay relay supplies 120VAC to the oven fan relay, these normally open contacts now close supplying 208/240VAC to the main fan motor. 120VAC is also supplied to the cooling fans. 208/240VAC is supplied to the primary of the control transformer, the conveyor motor and, through the air pressure switch, to the oven control. TEMPERATURE CONTROL Closing the main power switch supplies 208/240VAC to the primary of the control transformer. 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 208/240VAC to the coil of the heater relay at intermittent intervals to maintain the desired temperature. The display on the oven control will indicate when the heater relay is energized. NOTE: The display also indicates oven temperature. CONVEYOR DRIVE Closing the main power switch supplies 208/240VAC 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 conveyor motor is not running, “BELT JAM” is indicated on the display. AUTOMATIC COOL DOWN When the oven is started, the time delay relay timing circuit is enabled, permitting the oven fans to run approximately 20 minutes after the oven is shut off, to cool the oven. The time delay relay will keep the coil of the fan relay closed, maintaining operation of the main fan and cooling fans. Impinger II – Advantage Digital Express Service Manual - Dome...
