2-6 Description 8. Functioning The functioning of the unit is described here. The operation of the individual components is described in the manual for the component (refer to Index of Documentation). Melting Process and Hot Melt Material Supply The adhesive is placed in the tank. There it is heated to the processing temperature stated by the manufacturer or to the temperature set by the user. The melted material flows to the gear pump. The gear pump driven by a motor feeds the material to the hose connection fitting. From here the material flows through the heated hose to the hot melt material application head or to the hot melt material handgun. Motor See also manual Motor. The electronically controlled motor drives the gear pump. The motor speed is indicated on a display. To set speed see manual Control System. NOTE: The motor is only then ready for operation when the undertemperature locking device has been released or when the unit has almost reached the set nominal value temperature. NOTE: Avoid a permanent motor/pump speed of less than 5 RPM and more than 80 RPM to prevent excessive wear. Gear Pump See also manual Gear Pump. The gear pump is driven by a motor and feeds the hot melt material to the hose connection fitting. The size and speed of the gear pump determine the material feed quantity. NOTE: Nordson gear pumps may not be operated without hot melt material. Before switching on the motor, make sure the tank is filled. NOTE: Avoid a permanent motor/pump speed of less than 5 RPM and more than 80 RPM to prevent excessive wear. Shut off Valve (Option) Fig. 2-3 2 1 XXSY036S050A0595 The shut off valve is located in the safety valve plate which is between the tank and gear pump. It serves to block the flow of hot melt material when the gear pump is to be replaced. It is activated with a hex spanner. Position 1: shutoff valve open Position 2: shutoff valve closed. 2002 Nordson Corporation

Description 2-7 Mechanical Safety Valve (Standard) See also manual Safety Valve. The mechanical safety valve limits the hot melt material pressure produced by the gear pump and keeps it constant. It is factory set and lead sealed. When the factory set pressure is exceeded, the safety valve opens and the hot melt material circulates inside the safety valve plate. Pneumatic Safety Valve (Option) See also manual Safety Valve. The pneumatic safety valve has the same safety function as the mechanical safety valve. In addition, it offers the possibility to set the hot melt material pressure to a certain value or to control it dependant on the parent machine speed. Level Control (Option) See also manual Switch Amplifier CSV with Level Sensor. For level control purposes, two capacitive sensors are built into the wall of the tank and electrically connected to a switch amplifier. The lower tank level is shown by the indicator light (yellow). The potential free relay outputs Indication Fill and Indication Full (Interface XS 2) can be used e.g. to activate external signal transducers. Heated Can Receptacle (Option for MC 12) The heated can receptacle is built into the upper part of the tank and can accomodate 2.5 kg cans with a diameter up to 144 mm and height of up to 180 mm. The temperature of the can receptacle and the tank is controlled through separate heating channels. Bar Graph (Option) See also manual Control System. The bar graph simultaneously shows the range in which the temperature is for all channels that are switched on. 2002 Nordson Corporation

2-8 Description Heating and Temperature Control The melting zone is heated with cast in heating elements. They provide optimal heat conduction and energy utilization. The temperature is measured by sensors and regulated electronically by the temperature controller. Undertemperature Locking Device The undertemperature locking device prevents the unit or system from starting up when the hot melt material is too cold. It is activated until the nominal temperature value minus undertemperature value has been exceeded. On initial heating of the unit, the locking device is first released when the actual temperature is 3 C below the nominal value temperature. The undertemperature locking device locks the motors, solenoid valves and, in some cases, other components of the hot melt material application system. Refer to the Wiring Diagram to determine which components are locked. Overtemperature indication / shutdown The independently operating overtemperature shutdown mechanisms protect the unit and adhesive from overheating. For overtemperature shutdown, the heating and motor are switched off. The red indication lamp collective fault lights up. Overtemperature indication through temperature controller: Switches relay output collective fault when setpoint temperature value plus overtemperature value has been reached and the red indication lamp lights up. The unit remains ready for operation. Overtemperature shutdown through temperature controller: The overtemperature shutdown value is set automatically 30 C above the highest temperature setpoint value. NOTE: Depending on the adhesive used, the overtemperature thermostats of the tank and possibly of the optional can receptacle may need to be adapted to the maximum processing temperature of the adhesive (This may mean that the overtemperature thermostats have need to be replaced). However, the switchoff value of the thermostat may not exceed the max. operating temperature of the unit! For thermostats see section Specifications. WARNING: When the overtemperature shutdown is triggered, there is either a fault in settings or unit malfunction. Switch off the unit and have the fault eliminated by qualified personnel. Temperature Setback Serves to protect the hot melt material and save energy during interruptions in production or work stoppages. Setback value and setback period are adjustable. 2002 Nordson Corporation

Description 2-9 Inert Gas Equipment See also manual Inert Gas Equipment and manual Control System, Operation of the Motor Section, Parameter Con, CoF and C1. NOTE: The parameters Co OFF and Co On (inert gas equipment) described in the manual Control System, section Operation of Temperature Part are not part of this system. CAUTION: Use only suitable inert gas. Refer to the Material Safety Data Sheet of the material or contact the material supplier. The inert gas prevents the material in the tank from reacting with humidity. It displaces the air in the tank and thus protects the material from an undesired reaction which may cause the material to harden sooner than it should. Inert gases are e.g. nitrogen (N) and carbon dioxide (CO 2 ). The advantage of carbon dioxide is that it is heavier than air and literally floats on top of the material in the tank. NOTE: A diaphragm compressed air dryer, including preceding high performance compressed air filter, for conditioning compressed air such that it can be used as inert gas, can be purchased from Nordson. The inert gas supply is carried out: Automatically during operation as set on the Control System (inert gas injection interval and duration of injection). Automatically after the tank hood is closed. The duration of injection can be set (Parameter C1). Manually by pressing the Purge button as an additional Inert gas flush, e.g. when the tank has been filled. When the inert gas pressure is too low, the illuminated symbol Inert gas bottle empty lights up. In addition, a potential free contact for connection of external indication devices is available (XS 2 Interface). CAUTION: When the main switch is set to 0/OFF, the inert gas equipment is turned off and the tank is deaerated. This can lead to hardening of the adhesive in the tank (Also refer to Daily Shutdown). 2002 Nordson Corporation

Operation 4-1 Section 4 Operation WARNING: Allow only qualified personnel to perform the following tasks. Observe and follow the safety instructions in this document and all other related documentation. 1. Filling the Tank WARNING: Hot! Risk of burns. Wera safety goggles and heat-protective gloves. Risk of burns from the tank lid when the tank hood has been opened. Hot adhesive can splash out of the tank when it is being filled. Insert the adhesive carefully. Before filling the tank, make sure the tank and hot melt material are clean and free of foreign substances. Foreign substances can damage the unit and accessories. Also ensure that the inert gas inlet hole and the tank deaeration hole are not plugged with adhesive. NOTE: Do not completely empty the tank. If there is too little adhesive in the tank, the adhesive can overheat. This can cause adhesive residue and hardening, resulting in malfunctioning. Maximum Filling Level Ensure that the melted adhesive can not reach the inert gas inlet hole and the tank deaeration hole. Tank with Optional Can Receptacle Carefully insert the open can with the opening down. If necessary, use a thorn to punch a hole in the bottom of the can. This avoids formation of a vacuum in the can; a vacuum could prevent the adhesive from flowing out. MCTK030S050A01998 Fig. 4-1 2002 Nordson Corporation
