9224x3FC Three Zone Final Cure Oven Systems
The 9224x3FC Final Cure Oven is designed to dry coatings that have been applied to panelized parts. The system consists of three pairs of infrared sources that are independently temperature controlled to within 2º C providing highly uniform, repeatable drying to substrata. An additional drying element, convection heat is added via forced hot air system that simultaneously exposes the panelized substrata to convection heat an infrared radiation. A system exhaust is also supplied to provide the required air movement to remove any evaporated solvents.
The conveyor drive is a V-belt to minimize contact area between the panelized substrata and the drive belt. The conveyor speed is controlled to within 1% of full speed and is a direct drive DC motor control.
SIDE CONTROLS: Left or Right Operator Controls.
EXIT EXTENSION: 20" [508mm] long, 60" [1524mm] long, or 60" [1524mm] long
with Forced Cooling Section.
PARTS: Recommended Spare Parts Package.
ENTRANCE CONVEYOR: Optional Entrance Height Adjustment for on the
fly manual adjustment for different width sizes of boards.
HEAVY BOARD SUPPORTS: Recommended when workpieces are between 2 lbs/ft²[9.8 killograms/m²] and 7.5 lbs/ft² [36.6 killograms/m²].
ELECTRICAL SERVICE REQUIREMENTS
Circuit Breaker service is 3-phase configuration with a good Ground.
EXHAUST SERVICE REQUIREMENTS
Exhaust and ducting to be supplied by user.
Machine is equipped with an interlock that will not allow activation of the heat sources without proper exhaust.

Make-up air to the installation area must be at least 1000 cu ft/min [28 cu m/min] for the 9224x3FC. Insufficient make-up air will result in fumes and poor temperature distribution; therefore, causing the machine to operate improperly.

CONTROL AND OPERATING SCHEME 9224x3FC THREE ZONE FINAL CURE OVEN
These are the 9224x3FC’s major components. The following figures help identify specific elements of the machine for operation. The operator needs to be completely familiar with these elements prior to attempting to operate this equipment. Argus International will provide on site training for process, operation and maintenance upon request.

- Adjustable Entrance Conveyor: An up and down adjustment for smooth transfer from other conveyor systems to the 9224x3FC. The 9224x3FC
comes standard without an Adjustable Entrance Conveyor; contact an Argus Sales Representative to have this feature installed.
Stop Sensor: The sensor (1SEN) sends a signal to sound an alarm if the conveyor fails or falls below .80 feet [.24 meters] per minute.
The Conveyor Stop Alarm Board cuts power to heater contactor (1CON) and auxiliary contacts (AUX1 and AUX2) disabling power to the
Heaters and Temperature Control Boards.
- V-Belt Conveyor: The materials coming into the 9224x3FC may still wet with LPISM. It is necessary
to provide a means to convey the part without touching the surface. The V-belt conveyor design allows conveyance without touching
the panel surface. If the panel weight exceeds 4-lbs/sq ft [19.5-kgs/sq m], then the heavy board feature must be installed; contact
an Argus Sales Representative to have this feature installed. Do not exceed 8-lbs/sq ft [39-kgs/sq m] when the heavy board option
- Control Panel: User’s interface to communicate with the machine. Panel contains: indicators, meters, pushbuttons, switches,
and potentiometers. See section 1.3 in the manual for the breakdown for the control panel.
- Emergency-Stop Switches: Used to cut power
to the system controls such as: conveyor, heaters, convection fan, and cooling fans (if installed). These switches do not cut off
main power on the machine (see Circuit Breaker).
- Zone 1 Heaters: Heater panels emitting energy between 5 and 8-micron wavelength provide
the ideal preheating stage for tack drying or curing without skinning over the liquid coating.
- Zone 2 Heaters & Convection: Includes
the same 5 to 8-micron heating source that Zone 1 employs with the added capability of sending high velocity air movement to break
down the vapor barrier that forms on the surface of the PCB during drying.
- Zone 3 Heaters: The final heater zone provides some additional
dwell time allowing completion of the tack-dry or curing process.
- Convection Fan: High velocity air for Zone 2 is supplied via convection
fan. All ductwork is internal.
- Exhaust Outlet: The 9224x3FC disposes the evaporated solvents through the exhaust. An external blower
rated at 1000 cu ft/min [28 cu m/min] and proper size ducting must be connected to this outlet.
- Additional Cooling Fans: An extended
cooling zone outside the heater cabinetry used to reduce the panel temperature. Air ducts can be attached to four individual 4” [102mm]
outside diameter openings integrated to the fan banks, so cooler air can be introduced into the cooling section. Contact an Argus
Sales Representative to have this feature installed.
- Conveyor Drive Motor: The conveyor can be adjusted from 1.70 to 7.00 feet [.52
to 2.1 meters] per minute. The drive end is equipped with a 90VDC clutch. When the “System ON” indicator is not lit, the operator
can move the conveyor manually using the hand-wheel located near the control panel.
- Circuit Breaker: Where the main and control power
of the machine can be switched ON or OFF.
- Electrical Component Enclosure: This cabinet contains the electrical wiring, components,
and control boards.
