Functioning of the individual components is described in the manual of the component in question (Refer to Document Index). Melting Process and Adhesive Flow Refer to Fig. 2-2. The tank in the MC 200 series is divided into a low melt section (2) and a high melt section (4). The temperature barrier allows the adhesive in the low melt section to be gently melted at a low temperature. The adhesive is then melted to processing temperature in the high melt section. The hot melt adhesive drum (1) is inserted into the low melt section (2) with the bottom open. The adhesive is melted by the melting grate (15). The processing temperature prescribed by the manufacturer in the safety data sheet is decisive for setting the temperature. The adhesive flows from the melting grate into the reservoir (3) and then into the high melt section (4). From there it flows through the suction hole (11) and into the gear pump (14). The gear pump, driven by an electronically controlled motor (5), conveys the adhesive through the bypass plate (7) to the hose connection fitting (9). The safety valve (8), located in the bypass plate (7), limits the adhesive pressure generated by the gear pump (14) and keeps it stable. It is factory set and lead sealed. When the set pressure is exceeded – e.g. when the nozzle of an application head is closed – the safety valve opens, and the adhesive circulates within the bypass plate. NOTE: Units with a torque motor are not standardly equipped with a bypass plate and safety valve. They are offered as options and then used as a pressure control valve.

The adhesive is conveyed from the unit (1) through a heated hose (2) to a hot melt application head (3), which then applies the adhesive to the substrate. The heated hose and the application head are accessories. 1 2 3 MCSY702L093A0399 Fig. 2-3 Example of a hot melt material application system 1 Unit Heating and Temperature Control 2 Heated hose 3 Application head The tank (high melt and low melt section) is heated by cast–in heating elements. They guarantee optimum heat transfer and energy efficiency. The temperature is measured by sensors and is electronically controlled by the temperature controller. In addition to the heated low melt and high melt sections, the unit has a heated cover with its own temperature controller. Undertemperature Locking Device The undertemperature locking device prevents the unit or system from starting up when the adhesive is too cold. It is activated until the temperature setpoint minus undertemperature value has been exceeded. Upon initial heating of the unit, the locking device is first released when the actual temperature is 3
C (5.4
F) below the temperature setpoint. 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. P/N 412628A MC 201 / MC 203 / MC 204 / MC 210 Issued 03/99 E 1999 Nordson Corporation All rights reserved Description 2-9 Overtemperature Switchoff Heating and Temperature Control (contd.) Three independently–operating overtemperature switchoff mechanisms protect the unit and adhesive from overheating. For overtemperature emergency switchoff, the heating and motor are switched off. S Overtemperature switchoff through temperature controller: Switches off when temperature setpoint plus overtemperature value has been reached. S Overtemperature emergency switchoff through temperature controller: The overtemperature emergency switchoff value is automatically set 30 °C (54 °F) above the highest temperature setpoint. S Overtemperature emergency switchoff through overtemperature fuse: Serves as an emergency switchoff in case the overtemperature switchoff and the overtemperature emergency switchoff through the temperature controller do not function properly. The fuse is located behind the cover of the heater connection on the melt tank, in a black protective hose. The overtemperature safety switchoff is triggered at approx. 152 °C (305 °F); it switches off the heater. When the switchoff has been triggered, it must be replaced (P/N 262 132). X WARNING: Risk of electrical shock.Before replacing, disconnect all phases to the unit from the power supply. Failure to observe can result in injury, death and/or damage to the unit and accessories. WARNING: When the overtemperature switchoff is triggered, there is either an incorrect setting or a unit malfunction. Switch off the unit and have the fault eliminated by qualified personnel. Temperature Setback (Standby) Serves to protect the adhesive and save energy during interruptions in production or work breaks. Setback value and setback period are adjustable. E 1999 Nordson Corporation All rights reserved MC 201 / MC 203 / MC 204 / MC 210 Issued 03/99 P/N 412628A 2-10 Description Controlling Motor The gear pump is driven by an electronically controlled motor. Various parameters and the operating modes manual mode and tach mode can be set on the electrical cabinet. Manual mode (speed or torque steady) In manual mode, the motor/pump speed of units with an A.C. gear motor WS 0370 is the same as the speed set on a built–in speed dial (6, Fig. 2–4) in the electrical cabinet. The speed is kept stable at a set value. The speed (= output quantity) of units with a torque motor DM 200 is adjusted on a torque dial built into the electrical cabinet (6, Fig. 2–4). NOTE: Depending on the set torque and the setting of the safety valve (8, Fig. 2–2), a closed application head nozzle can result in standstill of the torque motor. Tach mode (pilot voltage–controlled operation) In tach mode, the motor/pump speed of units with an A.C. gear motor WS 0370 is controlled synchronously to the speed of a parent machine. But tach mode is possible only when pilot voltage is connected to the unit. NOTE: This mode is not possible for units with a torque motor DM 200. Actual Speed Compiler (Only on Model with WS 0370) P/N 412628A The actual speed is compiled with a sensor that scans a toothed wheel rim mounted on the gear output shaft without actually touching it. The impulses thus generated are evaluated and displayed in the speed display (7, Fig. 2-4) as the actual speed. Also refer to manual Actual Speed Compiler.

Wait until the unit, hose and application head have reached the set temperature and the undertemperature LED for the temperature controller has gone off. 9. Press button Motors on to switch on motor. 10. Set required adhesive output quantity. 7. Setting Temperatures Details regarding temperature setting can be found in the manual Temperature Control. The following points are of general relevance: NOTE: In the description of the temperature controller, the processing temperature is also referred to as setpoint temperature. NOTE: When setting the temperature, the temperature prescribed by the hot melt adhesive manufacturer is decisive. NOTE: The maximum operating temperature (Refer to section Specifications) for the unit, application head and heated hose may not be exceeded. Nordson will assume no guarantee and/or liability for damage resulting from incorrect temperature settings. Heating Zones In addition to the heated high melt and low melt section, the unit is equipped with a heated cover with its own temperature control. Overtemperature The overtemperature value is usually set 10 to 30 _C (18 to 54 _F) above the setpoint. If the actual temperature in the heating zone exceeds the overtemperature value, the heater is switched off. Depending on the temperature control method, the heater either automatically switches on after the heating zone has cooled off, or the unit must be switched off for a moment and back on again (Refer to manual Temperature Controller ). Undertemperature To prevent damage to the unit when the hot melt adhesive is too cold, the drive is blocked until all heating zones have reached the undertemperature value (approx. 10 to 30 _C (18 to 54 _F) below the setpoint). If during operation the temperature in the zone falls below the undertemperature value, the drive is also blocked. WARNING: If the button Motors on has already been pressed, the drive starts automatically when the undertemperature value is exceeded. E 1999 Nordson Corporation All rights reserved MC 201 / MC 203 / MC 204 / MC 210 Issued 03/99 P/N 412628A 4-6 Operation 8. Setting Adhesive Output Quantity (Only on Model with WS 0370) The output quantity is set with the speed dial. The optimum setting depends on the customer’s adhesive application and must be determined by trial and error. NOTE: Nordson gear pumps may not be operated without adhesive. Before switching on the motor, ensure that the tank is filled with adhesive. NOTE: To prevent excessive wear, the pump speed should not continuously exceed 80 min-1. CAUTION: If the drive is already switched on, it automatically starts up after release of the undertemperature lock. 1. Set switch Manual/automatic to Manual. 2. When the set temperature has been reached and the undertemperature lock has been released, the drive can be switched on by pressing the button Motor on. The required output quantity (pump speed) is set with the speed dial in the electrical cabinet door (4, Fig. 4-1). Setting 10 = 100 min-1. The pump speed is displayed digitally in the speed display (10, Fig. 4-1). If a pilot voltage transducer or a tach generator is connected to the connection socket (7, Fig. 4-1), the pump speed can be controlled dependent on a separate machine. The pilot voltage (tacho voltage) of the tach generator is always supplied to the motor control unit via an electronic isolating amplifier. 1. Adjust tach generator (Refer to manual Tach Generator ) CAUTION: The set pilot voltage may not exceed 160 VDC. 2. Calibrate isolating amplifier (Refer to manual Isolating Amplifier ). P/N 412628A MC 201 / MC 203 / MC 204 / MC 210 Issued 03/99 E 1999 Nordson Corporation All rights reserved Operation 4-7 9. Setting Adhesive Output Quantity (Only on Model with DM 200) The adhesive output quantity (application weight) needed depends on the customer’s adhesive application and must be determined by trial and error. Without Pressure Control Valve The adhesive output quantity or the torque is set with the torque dial (4, Fig. 4–1) within the range of 0 to 100 %. The desired setting should be locked into place to prevent unintended adjustment. NOTE: Torque motors have a special way of functioning. They do not rotate steadily at one speed; instead they serve to provide torque during standstill or at any partial speed. In practice this means that the motor comes to a standstill when the nozzle of a hot melt adhesive application head is closed and resumes operation when the nozzle opens. With Pressure Control Valve (Option) A more even adhesive output quantity can be set on units equipped with the optional safety valve – used as a pressure control valve on this unit. The pressure control valve (8, Fig. 4-1) is located between the tank and the gear pump. Setting range 0 to 7.0 MPa 0 to 70 bar 0 to 1015 psi Factory setting 3.5 MPa 35 bar 508 psi Turning to the right Increases adhesive pressure / output quantity Turning to the left Decreases adhesive pressure / output quantity 1. Set torque dial to value needed. 2. Set the pressure control valve such that the motor speed remains virtually steady when the application head nozzle is closed. 3. Alternately adjust the torque dial and the pressure control valve to set the adhesive output quantity as evenly as possible. 4. Lock speed dial into place.

Cleaning Overflow Prevention Pipe The inert gas line serves as an overflow prevention pipe (17, Fig. 2-2). It prevents uncontrolled outflow of hot melt adhesive when the low melt section is overfilled. If the adhesive should overflow, the pipe can be easily removed and cleaned. To do this, remove the overflow prevention pipe and, while still warm, use suitable, non–scratching objects to push through the pipe. 13. Units with Several Pumps P/N 412628A If a pump area of units with several, separately controlled pumps is not used for an extended period of time, the hot melt adhesive must be regularly (at least once per week) conveyed out of the unused pump area. This prevents the adhesive from burning due to conducted heat. MC 201 / MC 203 / MC 204 / MC 210 Issued 03/99 E 1999 Nordson Corporation All rights reserved Maintenance 14.
