Danger, warnings and cautions are designated by a dark frame with a shaded background. The level of safety hazard for each heading is described in the following example illustrations: DANG ER Danger indicates imminently hazardous situations where a potential hazard or unsafe practice will cause death or serious personal injury. W ARNI NG Warning indicates hazardous situations where a potential hazard or unsafe practice could cause death or personal injury. CAUTION Caution indicates situations where a potential hazard or unsafe practice could cause equipment or products to be damaged or minor injury if the instructions that follow the notice are not strictly observed. Notes relate to additional information about a procedure but do not usually relate to safety. They have a light frame border with no shading. An example of a note is illustrated below: NOTE: Note indicates any additional information about a procedure. 9 Furnace Safety Features The model TCA furnace contains the following safety features: 1. 2. Emergency Stop Buttons Over Temperature Protection Heating Zone Over-Temperature Cooling Section Over-Temperature 10 3. Conveyor Protection 4. Lockable Power Disconnect Switch 5. System Interlocks Emergency Stop Buttons (EMO’s) EMO EMO The Start power will be turned off, which turns off heat and will cause the zone temperature to slowly drop. This furnace configuration also turns off, the conveyor and gas controls, cooling system, and case cooling. 11 EMO Over-Temperature Protection WINCON Temperature Deviation Alarm Alarm Level 10°C 810°C Alert Level 5° C 805°C Setpoint 800°C 800°C When the FCU senses 810°C it will generate a signal that will deenergizes the Heater Power Contactor. 12 Recipe Over-Temperature Protection Alarm LED Indicators OVER TEMPERATURE MODULE 1 CH 1 2 3 CH 2 4 5 6 7 J2 J1 9 CH 5 10 CH 6 RESET PWR ON J3 13 CH 7 CH 8 J4 CH 3 CH 4 8 Reset Button (Same Function as Heat Off/On Switch) T/C Input Connecto rs J1, J3, and J4 CH 9 CH 10 Channels 7 through 10 are Omitted in 6 Channel Version. The Overtemperature Module’s setpoints are preset at the factory (to ≃ 25°C above system software limits) and should not be changed. Each heated zone is monitored by an overtemperature T/C that is independent from the zone control circuitry. If any zone exceeds the preset safe maximum temperature, the overtemp condition causes the module to shut off all heater power and generates an alarm with the WINCON software, puts the system into a purge mode but the Conveyor is maintained running for removal of product. Module Conveyor Protection 120 VAC C360-TR 333-LS C370-TR Conveyor Spocket As the Conveyor drive shaft rotates the sprocket turns moving C360-LS, which supplies 120 VAC power to either the C360-TR or the C370-TR. These relay are Time Delay to Make (TDM), set for the minimum conveyor speed. If the conveyor stops moving or is to slow, one of the relays will energize and provide an alarm to the WINCON software.

CRUSH HAZARD (Red and Black) 16 WARNING This equipment contains Refractory Ceramic Fibers (RCF) that have been identified by the International Agency for Research on Cancer (IARC) as a possible human carcinogen (Group 2B). Exposure to RCF may be hazardous to your health. Under normal operating conditions, exposure should not occur. If maintenance is to be performed on this equipment, or if exposure to RCF otherwise occurs, then precautions should be taken for the handling of RCF. The necessary precautions and emergency procedures are described in the MSDS sheets included in the technical manual supplied with this equipment. Further information on RCF may also be obtained from: The Carborundum Company - Fibers Division. HOTLINE NUMBER (716) 278-2183.

Wear safety glasses and protective clothing when working on the system. Whenever possible, make sure that both compressed gases and electric power are turned off at the source prior to beginning any maintenance task. Do not attempt to defeat any of the interlock switches or the safety features that are built into the system. Make sure that all access panels or doors are closed and latched when they are not being used for maintenance. 20 Good Safety Practices Periodically check the operation of all the safety interlock in the system Be careful when using flammable solvents such as alcohol for cleaning. Make sure that the electric power is off and the equipment is cool enough to prevent a fire hazard.Observe all safety warning labels. Never remove a warning label from the system. Never operate damaged or leaking equipment. Make sure that the electric power to the system is turned off using the lockout/tagout procedure before connecting or disconnecting cables. 21 Good Safety Practices Turn off the furnace and disconnect the power from the source before moving the system. Move the furnace with care. Sudden jolt or drops can damage the equipment. Report any unsafe conditions or situations immediately. 22 MSDS Material Safety Data Sheet Three questions to ask 1.

The board will operate with only a 15 volt DC power supply. No other external connections and apparatus are need for it to operate. The FCU is normally connected to a IBM compatible PC, to simplify programming and for storage of information. A PC with WINCON® software operating an a RS-232 (COM) port interface with the FCU. The FCU is equipped with 31 analog inputs and 36 analog output, they are generally used as closed looped controlled I/Os. These ports are used to control heated zones, static pressure in a close loop configurations. The analog inputs can be used without outputs to monitor activities like O2 or dew point. The analog outputs can also used independent of inputs. Equipment with cooling fan control operate this way, to allow the FCU to control fan RPM. We utilize 16 digital output to control external options like Gas flow. Sixteen digital inputs, monitor external events and alarm condition such as Low Pressure switches. There is Lithium battery pack on every FCU board to maintain data time and configurations for a ten year period. This allows the FCU board to maintain information on how long it has been on or off and all calibration values. 86 Tool Bar Status Indicator Display Status Button INIT Description This is your furnace’s state when first turned on (i.e., initializing). In this state, communication between the PC and the FCU are established, but the FCU has not completed its initialization. The initialization process may take several seconds. (Displayed in black text with a yellow background). The furnace is in the idle state when the heater power contactor has not been turned on yet. (Shown in black text on a yellow background). IDLE SETUP READY After changing the recipe, the furnace stays in the SETUP state until the temperature reaches the alert band and remains within this band during the preready dwell time with no alarms. (Black text, yellow background). Furnace has stabilized and is ready to process (shown in black text with a green background). The READY state occurs after the time-out of the pre-ready dwell period if no alert or alarm conditions exist. In addition, the following conditions must also be met: Temperature is within the alert/alarm band Conveyor speed is within the alert/alarm band Edge conveyor chain is at the correct width Other conditions may exist depending on options HOLD 87 Power has been off longer than the power down time limit (shown with black text on a yellow background). In the HOLD state, the controller maintains the temperature levels that existed in the furnace when power was restored Tool Bar Status Indicator Alarm States Display Status Button Description Indicates the presence of alert conditions (shown in flashing black text on a yellow background). You must correct the problem to clear the alert ALERT ALARM 88 Indicates the presence of alarm conditions (shown in flashing white text on a red background). You can silence the audible alarm by acknowledging it in the Status/Alarms screen. You must correct the problem to clear the alarm.
