17 FM-l 30 Applicators Manual 41-l 30 Page 2-1 SECTION 2 EQUIPMENT FAMILIARIZATION GENERAL DESCRIPTION The Nordson FM-130 series of FoamMelt@ processors feature state-of-the-art computer technology to control the combination of thermoplastic materials with precisely metered quantities of inert gas and then deposit a foam of uniform density onto a substrate. The FM-130 is composed of three feature levels. Standard on the FM-131, FM-132 and FM:-133 are: Onboard Liquid 11 Electrical Parent microprocessor and tactile membrane keypad control of most functions Crystal Display (LCD) and menu-driven function programming temperature channels with control accuracy to within a 3 F (2 C) setpoint band self-diagnostics with error message display and remote alarm output Machine Interlock for application line operation only after proper hot melt material density reduction and pressure have been reached Operator-adjustable, low-temperature standby mode Remote, automatic: and manual modes for system startup, shutdown and temperature standby Operator-selectable sequential heater channel startup The FM-132 processor features all of the above, plus the following pattern control features: Four-channel Timer Adjustable timer with delay and duration settings to control gun firing or gear-to-line mode operation for consistent bead placement when he speed varies 50% duty cycle stitching for equal bead/gap length selectable on each timer Publication No Nordson Corporation 1990 Issued 9190

18 Manual 41-l 30 Page 2-2 FM-l 30 Applicators The FM-133 includes all of the above, plus the following pattern control feature: Run-up control for consistent bead thickness when line speed varies The FM-130 processor is powered by a 3/J-hp AC motor. This motor, in turn, drives a corrosion-resistant,.patented, two-stage gear pump located at the bottom of a heated, one-piece, cast aluminum tank. FM-130 HOSES, GUNS AND RELATED EQUIPMENT The FM-130 is an externally recirculating system, therefore, each dispensing gun requires a supply and a return hose. Up to 6 hoses and 4 automatic extrusion guns can be connected to the FM-130 processor and up to two circulating handguns can be connected. All use Resistance Temperature Detection (RTD) to sense and control temperature. The Nordson conventional, automatic, water-resistant and biaxial hoses can be used with automatic guns configured to the FM-130. Hoses are also available with timer leads to activate gun solenoid valves when using the FM-130 timer. Nordson offers a different biaxial hose (no timer leads) for use when the biaxial handgun is configured to the FM-130. Hose/gun accessories include: A A Special special circulation fitting for configuring any of the automatic guns to a biaxial hose or a pair of standard hoses. Straight-in, 45 and 90 connection kits are available. water-resistant splitter and timer cable kit for configuring a conventional water-resistant hose (no timer leads) and water-resistant gun to an FM-130 unit. extension cords to supply power to a jumper hose beyond reach of the applicator and to connect a Y-connector (from two jumper hoses) to the FM-130 electrical socket #5.

21 FM-I 30 Applicators Manual 41-l 30 Page 2-5 Microprocessor Control (All Models) The FM-130 microprocessor controls all aspects of operation except density reduction and (in the FM-133) hydraulic pressure. The system operating values are programmed by the operator using the end panel keypad and LCD menus. All system setup data is stored in battery back-up, non-volatile random access memory (NV-RAM), therefore, the operator need enter the values only once. All data storeid in RAM is validated at power-up. If the stored data is invalid, default values are loaded for all parameters and an error message is displayed. The FM-130 microprocessor performs constant system diagnostics. If a system fault occurs, a warning message is displayed on the LCD. A minor fault will result in deactivation of only the circuit in which the fault exists. A :major fault will result in automatic shutdown of the motor and all heating zones. See Figure 2.3 for a schematic of the FM-130 microprocessor trol. con- System Ready Delay (All Models) This feature prevents operation of the FM-130 motor and gear pump until all heated zones have reached setpoint and a predetermined time period has elapsed. The system ready time delay (5-40 minute range) is preset by the equipment operator during the setup sequence and is based the time required for the adhesive in the tank to liquify. The delay period begins when all temperature channels are no more than 5 F (3 C) below setpoint. When the delay period has completed, the WAIT indicator LED will flash fast (2 Hz). This indicates that the motor is enabled and can be started. Parent Machine Interlock (PMI) (All Models) This feature prevents operation of equipment configured to the FM-130 until foamed mat(eria1 is ready for delivery and has reached stable density reduction and pressure. With PM1 enabled, the FM-130 energizes an internal electrical contact which permits activation of the packaging line or other equipment configured to the FM-130. Publication No Nordson Corporation 1990 Issued 9190

22 Manual 41-l 30 Page 2-6 FM- 130 Applicators The time delay ( second range1 is preset by the equipment operator during the setup sequence and is based on characteristics of the hot melt material being used. The time delay begins cycling once the motor is started. During the delay period, the WAIT indicator LED flashes slower (1 Hz). When the delay period has completed, the WAIT indicator LED will turn off and the PM1 relay contact is energized. Sequential Temperature Startup (All Models) The FM-130 features operator-selectable sequential startup, where each temperature channel is activated automatically in a predetermined order after a system self-check has been completed. The sequential startup sequence is: 1. Tank heater channel on. 2. Hose heater channels on setpoint). 3. Gun heater channels on 80 percent of setpoint). (after tank has reached 80 percent of (after all hose channels have reached Warm System Startup (All Models) 4. Begin SYSTEM READY delay (after all channels are within 5 F (3 C) of setpoint). 5. Enable motor start (after SYSTEM READY delay has elapsed!. 6. Begin PM1 delay (after motor has been started). 7. Activate PM1 output (after PM1 delay has elapsed). The temperature control system features warm system recognition to allow for faster system startup and operation after a brief power-down. Once the system is up to setpoint temperature and all time delays have completed, the microprocessor stores a hot indicator flag in memory at power-down. At power-up, if the tank temperature is within 50 F (27 C), of its setpoint, a warm system startup is executed. If the tank temperature is below 250 F (121 C>, the tank must be within 15 F (S C) of its setpoint temperature for the warm system startup to execute. Issued Nordson Corporation 1990 Publication No

23 FM-l 30 Applicators Manual 41-l 30 Page 2-7 The warm system startup sequence consists of: 1. Start all connected heater channels (do not perform sequential start, if enabled). 2. Wait for all channels to reach 20 F (11 C) of setpoint. 3. Enable motor immediately (do not perform system ready delay time sequence). NOTE: If the power-down occurs during the ready delay time period, only the remaining portion of the delay period must be completed. 4. Wait for the PM1 delay to complete. 5. Activate PM1 output and turn WAIT indicator LED off. Temperature Standby Mode (All Models) I-Day Clock (All Models) Temperature standby mode provides a means by which the heating channel temperatures can be lowered to retard hot melt material degradation. Standby mode is recommended when normal operation of the unit is interrupted for long periods of inactivity. The time required for the unit to reach normal operating temperature is reduced. The standby temperature is set by the operator via the computerdriven menu. Standby mode can be enabled/disabled via either a separate touchpad on the FM-130 front panel, the automatic clock feature or by a remote input signal. The motor and gun timer output signals are disabled in the standby mode. This features allows for automatic startup, shutdown and standby control of the FM-130 heater channels. The end panel touchpads and menu selections on the LCD screen are used to complete timesetting functions for heater startup, shutdown and standby mode. The system can also can be set up to display times in 12- or 24- hour format. If it is necessary to temporarily interrupt the clock-operated automatic functions, a separate touchpad on the front panel CLOCK) is used to enable and disable the function.

24 Manual 41-l 30 Page 2-8 FM-l 30 Applicators If the FM-130 motor is not started within 2 hours of system ready status after an automatic startup, all heater channels are set to standby mode. Pattern Control: Gear-to-Line, Timer Modes (FM-132 and FM-133 Units Only) These functions, used in conjunction with automatic extrusion guns, ensure that bead length and placement on the substrate will be consistent, regardless of changes in line speed. If the line speed remains fixed, the timer mode should be used and an electronic triggering device must be configured to the application line to provide a part present signal to FM-130 unit. If line speed varies, the gear-to-line mode should be used and both a triggering device and an encoder must be configured to the application line. The encoder provides a line speed signal to allow for the FM-130 timer to adjust when the gun should open (delay) and how long it should remain open (d.uratior-0. The delay interval is the period of timle from when the sensor trigger signal is sent to the FM-130 timer and when the FM-130 signals the gun solenoid valve to open. The duration interval is the length of time that the gun is actually open. FM-132 and FM-133 units can be programmed for both pull-in and drop-out gun compensation to allow for fixed gun and solenoid valve response time. Pull-in a.djusts the gun signal to be sent slightly before the substrate reaches the correct position on the packaging line. Similarly, drop-out adjusts the gun cut-off signal to be sent just before the substrate reaches the correct position on the line. Gun compensation in the FM-132 and FM-133 can be set for 0 to 50 milliseconds. Gear-to-line operation maintains bead placement at line speeds from 3 fpm to 1,000 fpm (1 mpm to 300 mpm). If the line speed drops below 3 fpm (1 mpm), the gear-to-line circuitry automatically inhibits the gun actuation signal, thereby preventing the guns from firing continuously if the line speed should stop during a duration cycle. Pattern Control: Stitching (FM-132 and FM-133 Units Only) Some applications require very short depositions called stitched beads. This stitching feature is also used in conjunction with automatic extrusion guns. The FM-130 produces stitched beads of equal length and gap (50 percent duty cycle) during the timer Issued Nordson Corporation 1990 Publication No B

25 FM-l 30 Applicators Manual 41-l 30 Page 2-9 duration cycle. The stitch feature can be selected for each of the four timer channels individually. Pattern Control: Run-Up (FM-133 Only) THE FOAMMELT PROCESS The FM-133 run-up function, used in conjunction with automatic extrusion guns, adjusts hydraulic pressure as line speed varies to maintain consistent bead thickness. If line speed drops, system hydraulic pressure is automatically lowered so that bead thickness is unaffected. Likewise, if line speed increases, hydraulic pressure is raised in order to deposit more material onto the substrate and maintain bead thickness consistency. Because run-up control is; a function of varying line speed, the gear-to-line mode rather than timer mode should be used and an encoder must be configurled between the application line and FM- 133 unit. The FoamMelt application system is a process by which an inert gas (usually nitrogen) is mechanically combined with a hot melt material and held in solution, much like a carbonated beverage under pressure in its shipping container. As the material is exposed to atmospheric pressure and deposited onto a substrate, the gas expands, producing foam. The FoamMelt process results in major improvements properties, including: Longer open time to adhesive Faster set time. Improved spreadability Volumetric increase for greater gap filling Improved Lower Reduced Reduced substrate wetting heat density sagging or running adhesive consumption. Increased penetration in porous substrate Publication No Nordson Corporation 1990 Issued 9190

27 FM-l 30 Appkators Manual 41-l 30 Page Mixing Process From the tank, melted material is fed into a constant displacement, two-stage gear pump where it is mixed with an inert gas. The most commonly used gases are industrial-grade carbon dioxide or nitrogen. The gas (customer-supplied) is metered into the material based on system demand. The FoamMelt system gear pump, comparable to a pair of standard gear pumps stacked one on top of the other in a single housing, is driven at a constant 300 rpm. The first stage (upper portion) of the pump meters material from the heated FM-130 tank into the second stage (lower portion) of the pump. The gas is injected at low pressure (3-5 psi) into the gear pump. Pump gear rotation creates a vacuum which draws the gas into the second stage gear set. Here it is combined with the hot melt material from the first stage. As the gas/hot melt mixture moves toward the pump discharge port, hydraulic pressure in the pump increases. This pressure forces the gas into solution with the hot melt material to form a single state fluid, like a carbonated beverage in its bottle or can. A series of mixing slots cut into the plates above and below the second stage gear teeth aid the combination process. As material travels through the gear pump, some is forced into a mixing slot instead of exiting through the discharge port. Material circulates repeatedly through the slots, ensuring that the hot melt and gas are thoroughly mixed before the solution leaves the pump. Hydraulic Flow From the gear pump, the hot melt/gas solution enters the FM-130 manifold where it flows through the density control/filter assembly. There, any solid particles, such as flakes of char, are removed and the gas/hot melt ratio is measured. From the density control/filter, material exits the manifold and enters one or more heated supply hoses. Material then circulates through automatic or hand-operated extrusion gun(s) attached to the end of the supply hoses. Remaining material re-enters the FM- 130 unit via heated return hoses connected between the guns and return ports in the manifold. Before material enters the gear pump return port in the manifold, it passes through a pressure control valve. The pressure control valve maintains system h:ydraulic pressure by means of a spring- Publication No Nordson Corporation 1990 Issued 9190

28 Manual Page 2-12 FM-l 30 Applicators loaded, ball-and-seat arrangement. The valve spring pressure is variable and can be increased or decreased by the operator to regulate system pressure. The FM-130 pressure control valve is located on the manifold, directly between the two return ports. On FM-131 and FM-132 units, the pressure control valve is manually adjusted by means of a slotted hex head screw-and-locknut arrangement. In FM-133 units, the run-up control valve requires only initial setting by the equipment operator; system electronic and pneumatic circuitry automatically adjusts the run-up control valve as the production line speed varies. Finally, hydraulic overpressure protection is provided by a pressure relief valve mounted in the bottom of the FM-130 tank. If hydraulic pressure reaches 1,500 psi (1.00 psi), the valve drains material from the manifold into the tank for recirculation. Gas Modulation System Carbon dioxide or nitrogen gas should be supplied to the FM-130 system from a user-supplied gas cylinder equipped with a regulator. Once connected, the gas flows through a pressure switch that signals the LOW GAS indicator LED when supply pressure falls below 30 psi (4.5 kpa). Past the pressure switch, are a pressure regulator and pressure gauge which permit the equipment operator to control input gas pressure to the pump. The actual flow of gas into the system is controlled by a reed valve. This valve is activated by the density control/filter when pump output flow indicates that more gas is needed. Turning the density control knob clockwise increases gas flow which increases the gas-to-material ratio and density reduction. Likewise, turning the density control knob counterclockwise decreases gas flow and the gas-to-material ratio and density reduction. A check valve mounted near the gear pump eliminates backflow of hot melt into the gas line. As the gas is supplied to the pump, it is drawn into the vacuum area created in the second stage of the gear pump and mixed with hot melt. Issued 9190 Q Nordson Corporation 1990 Publication No

29 FM-l 30 Applicators Manual 41-l 30 Page 2-l 3 Temperature Control System The FM-130 is equipped with a microprocessor-based temperature control system which monitors and regulates temperatures in the tank, hoses, guns and the FM-130 electronics enclosure. Heater control is accomplished through pulse width modulation and a proportional integral derivative (PID) control equation. Temperatures can be checked and adjusted by the operator at the end panel. The unit offers digital temperature readout of the actual and setpoint temperatures in either degrees Fahrenheit ( F) or degrees Celsius ( C). During start-up, the temperature control system examines RTD sensors and actual temperatures for fault conditions. If a fault is detected, the system responds selectively, depending on the type of fault detected. If any heater temperature channel reaches 455 F (235 C), the system shuts down. Of the 11 temperature control channels, the tank is the only one that must be connected for system operation. The software will only control and display hose and gun channels which are physically connected. A channel not connected is considered vacant. Hoses with vacant gun channels, that is with no gun connector attached, require a blue dust cap in the unused socket. Otherwise the FM-130 electrical self-diagnostics system will detect the open socket as an open sensor fau.lt. As described earlier, the FM-130 features an operator-selectable sequential startup option, where the system activates each temperature channel in a predetermined order. In non-sequential startup mode, all heating channels are energized simultaneously. In sequential startup mode, each channel must reach the preset start-up temperature before the next zone s heater is enabled. The startup temperature is slightly lower than the setpoint temperature. NOTE: Sequential start-up may increase applicator warm-up time beyond 30 to 45 minutes. To shorten the warm-u.p period, the sequential startup feature can be disabled as detailed in Section 4 of this manual. Publication No C 0 Nordson Corporation 1990 Issued 9/95

30 Manual Page 2-l 4 FM-1 30 Applicators NOTE: Some thermoplastic materials expand rapidly when initially heated. When using such materials, always employ the sequential startup feature. When all temperature channels are within 5 F (3 C) of the setpoint temperature, the system ready time delay begins to elapse. After this delay has elapsed, the FM-130 motor can be started and, if applicable, the PM1 delay begins. After this delay has elapsed, the parent machine is released for operation. FM-130 electronics enclosure temperature control is maintained by a thermistor-controlled fan. If the enclosure air temperature reaches 149 F (65 C), the fan switches on. If the enclosure air temperature reaches 167 F (75 C), an error message is displayed on the LCD and the system shuts down after a go-second delay.

In some cases, conversion formulas are given for methods of measurement. applicator bead bead thickness That part of the hot melt system which is used to heat thermoplastic material to its required application temperature and pump it to the hoses and guns. The FM-130 applicator consists of a tank, a pump, a distribution manifold, gas modulation system and a temperature-controlled heating system. A deposition of hot melt material, usually of several inches or more in length. The width of a hot melt bead on a substrate before the bead is compressed. Bead thickness is affected by system hydraulic pressure, the application line speed or by using a gun with a microadjuster, such as zero cavity extrusion guns. Increased system pressure and slower line speed both produce thicker beads. biaxial Relating to a specially designed and manufactured extrusion gun or hose where the hydraulic delivery channel and return channel are contiguous to each other.
