NOTICE If power and grounding connections are not done properly, the equipment will be damaged and the warranty voided. Ground the gear meter assembly as instructed here and in the individual component manuals. Make sure the gear meter assembly and its components are installed correctly to ensure proper grounding. Air and Fluid Hoses For static dissipation, use only electrically conductive hoses or ground the applicator / dispense valves. FIG. 8: Inlet Fitting • Air must be clean and dry, between 60-100 psi (0.41-0.68 MPa, 4.14-6.89 bar). Flush air line before plumbing in air filter assembly (234967). Plumb in air filter assembly near air drop site (upstream of PGM). Adding an air regulator to this line will provide more consistent dispense valve response times. • Connect a 1/4 in. OD air supply line to the inlet port on the PGM air supply inlet. Dispense Valve Follow the grounding instructions in the dispense valve manual. Connect Fluid and Air Lines NOTICE Route all fluid and air lines carefully. Avoid pinching and premature wear due to excessive flexing or rubbing. Hose life is directly related to how well they are supported. NOTE: To maximize system performance keep the dispense hose length as short as the application will allow. Follow the instructions in your separate component manuals to connect air and fluid lines. The following are only general guidelines. • The PGM gear meter assembly should be installed on the automation unit or in another appropriate place, as close as practical to the dispense valve. • For a remote mount dispense valve, connect a fluid line between the gear meter outlet and the dispense valve. Shorter fluid lines (hoses) will provide better fluid system response. 3A0260H 17 Installation Install Cable Assemblies 1. Connect servo motor power and feedback cables. 3.

If shot weights are inconsistent check feed pressure or reduce flow rate and repeat shot test. begin dispensing when the user presses . Dis- pense parameters and duration depend on the selected control. NOTE: Regular weight checks are recommended to ensure system is performing properly. Verify System Operation Use maintenance mode to manually check the operation of the PGM system components before switching over to automation control (normal operation). NOTE: Perform any of the following procedures while in maintenance mode. Set Inlet Pressure The inlet pressure reading should be in the range of 300 psi (2.1 MPa, 21 bar) to 1500 psi (10.3 MPa, 103 bar). The recommended inlet pressure should be 500 psi (3.4 MPa, 34 bar) lower than the outlet pressure. Follow steps in the supply system manual to set the inlet pressure. NOTICE Excessive inlet pressure will cause accelerated wear on the gear meter seals and the pump feed system. Feed System Pressure Drop During material flow, the PGM inlet pressure decreases. The amount the pressure decreases is the amount of pressure lost between the feed pump and the PGM inlet. With high viscosity fluids, long line lengths, or small diameter line sizes this pressure decrease can be thousands of psi (hundreds of bar). This means that the static pump pressure is set much higher than the PGM needs at its inlet. To prevent excessive static pressure at the inlet of the PGM, a dynamic regulator is recommended on air motor supply air. During dispense the normal pump regulator is active. During a stalled condition the dynamic regulator is active. Dispense Weight Verification 1. From maintenance screen, select Shot mode. 2. Enter a 10 second shot time. 3.

Refer to Gear Pump Maintenance Guide on page 49 for special notes regarding gear pump repair. 3. Remove six pump block shoulder bolts (4). NOTICE Pump section should be fully supported to prevent damage being dropped. It is recommended that the gear meter assembly be located on a work bench for service. 4. Remove drive assembly. See FIG. 23. is enough clearance between the drive gear (1506) and top plate (1501) to insert one spacer. Be sure to allow clearance for drive key (1508). 11. Continue pressing the drive shaft (1504) and inserting spacers until the shaft is free from the drive gear (1506). 12. The stud (1505) for the driven gear (1507) is press fit into the back plate (1503) and need not be removed if not worn. NOTICE The PGM pump design relies on a lap fit between components for performance and sealing. Be careful not to drop the gears (1607, 1608) or damage the mating surfaces of the pump plates (1601, 1603) and gear case (1602). To prevent damage, do not use pliers or screwdrivers to remove the gears. 13. Clean all components thoroughly before reassembly. The use of an ultrasonic cleaner is recommended. NOTICE Thicker materials may pump heating prior to disassembly. Do not expose the pump to thermal shock. Raise temperature at a maximum rate of 180°F (100°C) per hour. Do not exceed 400°F (204°C). Gradually cool the pump to room temperature. 5. Remove seal retainer fasteners (1515) seal retainers (1512), spacers (1510) and (1511). 6. Remove pump dowels (1509) using an arbor press. NOTICE Do not use a hammer to remove dowel pins as this will damage the pump. 7. Remove the pump plate screws (1514). 8. Separate the pump front plate (1501), gear case (1502) and back plate (1503). NOTE: Notches on the pump plates can be used to separate the plates. 9. To remove drive shaft (1504) from the drive gear (1506) several flat spacers 1/8 in. (3 mm) thick will be needed. These will provide clearance for the drive shaft key (1508) and the top plate (1501). 10. Support pump top plate (1501) and press drive shaft (1504) through drive gear (1506). Stop when there 3A0260H 47 Repair PGM-20 Pump Assembly NOTICE Do not hammer or force components together or damage may occur. Parts will drop into place if properly cleaned and aligned. Use of a compatible oil is recommended during assembly. 1. Place back plate (1503) on a table inside face up. 14. Align pump shaft key and slide coupling onto pump shaft. Tighten coupling bolt just enough to hold it’s position. 15. Attach servo motor, gear head, and top plate to pump assembly. See FIG. 20. 16. Separate coupling until proper gap is created. See FIG. 21. 2. Install the driven gear (1507) on stud (1505). 17. Tighten pump block mounting shoulder bolts to frame (4). 3. Place gear case (1502) onto back plate (1503). Check orientation of dowel pin holes to assure they align with the ones in the back plate. 18. Replace all electrical connections and fluid connections before applying fluid pressure and power. 4. Place the top plate (1501) on its edge on a table. Pass the drive shaft (1504) through the top plate from the seal side so that the boss on the shaft rests on the top plate. 5. Rotate the drive shaft (1504) to position the drive key slot at the top. Insert the drive key (1508) and driven gear (1506) 6. Grasp the top plate (1501), drive shaft (1504) and driven gear (1506) to prevent them from separating and carefully lower them into position onto the gear case (1502). 7. Rotate the gears several times to ensure free rotation. 8. Insert the dowel pins (1509) and check again for free rotation. NOTE: Dowel pins are not a press fit and may be installed using a plastic hammer if necessary. 9. Install pump plate screws (1514) and tighten to 85-105 in-lb (9.6-11.8 N•m). 10. Rotate the gears several times to ensure free rotation. 11. Apply a heat resistant, non-evaporating lubricant to the seal area of the drive shaft (1504). 12. Install new seals (1513). See FIG. 26 and FIG. 27. 13. Install spacers (1510, 1511), seal retainers, (1512) and seal retainer screws (1515). Tighten screws to 85-105 in-lb (9.6-11.8 N•m). 48 3A0260H Repair Gear Pump Maintenance Guide Review these guidelines prior to performing any maintenance on the pumps. • Do not run pump dry. • Do not pull from a vacuum or negative suction head. • Do not flush with water or other non-lubricating fluid. • Do not pump corrosives, abrasives and/or fluids carrying particles that may harm the pump. • Do not heat or cool pump faster than 180°F (100°C) per hour • Do not drop disassembled parts on a hard surfaces and do not let parts knock together. • Never strike the pump parts with an iron hammer. The parts are designed to drop in place if properly aligned. Use arbor press to insert or remove press fit components. • Do not use pliers to lift the gears. • Never use a screwdriver to pry the gears upward. • Apply clean oil or compatible fluid during assembly. 3A0260H 49 Repair Installing new heater units and RTD sensors 1. Prepare Gear Meter Assembly for Repair, page 37. 2. Disconnect the power cables from the heaters. 6. Remove the heaters and sensor from the block. NOTICE The heaters may be difficult to remove and removal depends on the system type. To ensure proper heat transfer and to avoid premature heater failure, System with through hole: Press out the heater element using an 0.125” (3 mm) diameter pin. System without through hole: Drill out the heater element using a 5mm (0.203 in.) drill bit. Do not increase the hole dia mt er. 3. Remove two M3 screws to remove the kit from the inlet block. 7. Clean any residue from both heater and sensor ports. 8. Installation is the reverse of removal. 4. Remove two M6 screws to remove the kit from the pump block. 5.

If a value too large is input, the machine could over-pressurize leading to ruptured components and serious injury. #1 to #6 Buttons Press to navigate to the Setup Screen with that number. For example, press #3 to navigate to Setup Screen #3. 3A0260H 89 Appendix A - User Interface Display Setup #3 Screen A #1 to #6 Buttons Drive Information Press to navigate to the Setup Screen with that number. For example, press #3 to navigate to Setup Screen #3. Motor Torque Delay Settings Display motor torque during dispense. If motor torque climbs above continuous torque an alarm is issued. See Errors on page 33. Cont. Torque Continuous torque rating of the motor. Larger values for the On Delay setting lead to larger pressures in the system. If a value too large is input, the machine could over-pressurize leading to ruptured components and serious injury. NOTE: The motor torque display is a good way to determine the maximum flow rate with a given viscosity. The Delay Settings affect the timing of the Dispense Valve opening and closing when a shot is initiated. The On Delay is the amount of time, in milliseconds, between a shot being initiated and the dispense valve opening. If the On Delay is set to 100 the machine will wait 100 milliseconds after a shot is initiated before opening the dispense valve. This will lead to a pressure build up between the meter and dispense valve until the dispense valve opens. The Off Delay is the amount of time, in milliseconds, between a shot completing and the dispense valve closing. If the Off Delay is set to 100 the machine will wait 100 milliseconds after a shot is complete before closing the dispense valve. 90 3A0260H Appendix A - User Interface Display Setup #4 Screen A #1 to #6 Buttons Press to navigate to the Setup Screen with that number.

There are two digital inputs, three digital outputs, and one analog input. All of these signals are routed to the I/O connector on the top of the controller. Other pins on the I/O connector include 24 VDC power, 24 VDC common, analog common, and a signal which is 24 VDC power only when the controller E-Stop switch is latched in. None of the signals are isolated; all are referenced to the ground plane of the control box. The following paragraphs describe typical connection methods for the automation controller signals. Digital Inputs The two digital inputs are Dispense Start and Job Complete. These inputs require a 24 VDC current sourcing output from the automation controller. See FIG. 40. If the automation controller uses relay contacts to activate I/O signals, the 24 VDC available at the gear meter I/O connector (pin 5) should be used to drive the inputs. If the automation controller uses high-side switching of 24 VDC, the automation outputs can be directly connected to the inputs as long as the 24 VDC common (pin 6) of the gear meter is able to be connected to the automation controller common. If the automation controller outputs are low-side switching (open collector) or a voltage other than 24 VDC, relays must be used as shown in FIG. 40. Automation PGM Control 5 24VDC Relay Contact Input Pin 1 or 2 Input Circuit FIG. 40 3A0260H 95 Appendix B - I/O Digital Outputs The three digital outputs are Dispenser Ready, Fault Present and In Cycle. These outputs perform high-side switching of 24 VDC and require a 24 VDC current sinking input at the automation controller. See FIG. 41. If the automation controller uses 24 VDC relay coils to receive I/O signals, the signals should be connected as shown in FIG. 41. If the automation controller inputs are current sourcing or use a voltage other than 24 VDC, relays with 24 VDC coils must be used as shown in FIG. 41. PGM Control Automation Pins 10, 11, 12 Load (750 mA max) 6 DC Common Output Circuit FIG. 41 96 3A0260H Appendix B - I/O Analog Inputs Relays The PGM receives a flow rate analog command from the automation. The 0 to 10 VDC analog input is referenced to analog common on the control. See FIG. 42. The reference for the automation controller analog output must be connected to the PGM analog reference (pin 8) for this signal to function properly. If the use of relays is required to condition the digital I/O signals, these are some examples of part numbers that could be used. PGM Control Automation For 24 VDC Coils: • Relay: Phoenix Contact Part Number: 2966171 For 120 VAC Coils: • 0 to 10 VDC Relay: Phoenix Contact Part Number: 2966197 Pin 7 _+- Voltage Pin 8 Analog Input FIG. 42 24 VDC From E-Stop The PGM provides a signal that can be used by the automation controller to monitor the emergency stop switch position of the PGM controller. See FIG. 43. +24 VDC Pin 14 E-Stop Switch FIG. 43 3A0260H 97 Appendix C - Theory of Operation Appendix C - Theory of Operation Theory of Operation Fault Present - This bit is RESET under the following conditions: Input and Output Signals 1. No Faults (alarms or warnings) are active. Terminology In Cycle - In Cycle signal is set at the beginning of a dispense cycle. It is reset at the end of the dispense cycle. The dispense cycle can end in two ways, depending on how the Job End mode is set: For the purpose of this document a digital signal is said to be SET when voltage is present (or above the minimum threshold). A signal is said to be RESET when the signal voltage is not present (below minimum threshold). Devices are referred to as SET when they are in their energized or active state. Digital Inputs Dispense Start - This is the Dispense Signal. The PGM unit will attempt to dispense at either the commanded flowrate while this signal is SET, dependent on mode. Control On - This input is reset when the E-stop button is pressed. Job Complete - This input can be used to signal a job end. NOTE: The dispenser ready signal is an important signal for the automation to monitor. When the dispenser ready output is not on, the LT may not be responding to requests from the automation. This could create the situation where the automation is running production, but the PGM is not dispensing any material. • If the Job End mode is set to remote, dispense cycle ends when the job complete signal is received from the automation I/O. • If the Job End mode is set to Display, dispense cycle ends when the Job End delay timer expires. See Appendix A - User Interface Display on page 81. Analog Input Flow Command - The flow command signal input represents flow requests. The voltage must be between 0 and 10 volts DC. The 0-10 volt signal is interpreted as a relative 0-100% flow command signal. The system must be in Remote Mode for this input to be used. See the Accessory Parts on page 76. Dispense Valve Solenoid - This signal will be set to energize the dispense valve solenoid at the beginning of a dispense cycle. 98 3A0260H Technical Data Technical Data Volume repeatability . . . . . . . . . . . . . . . . . . . . . . . . . . . +/- 1% Minimum Flow Rate . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 cc/rev model: 20 cc/rev model: 30 cc/min 40 cc/min Maximum Flow Rate . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 cc/rev model: 20 cc/rev model: 480 cc/min 1600 cc/min Minimum Dispensed Shot Size . . . . . . . . . . . . . . . . . . . 6 cc/rev model: 8 cc 20 cc/rev model: 10 cc Maximum Fluid Working Inlet Pressure . . . . . . . . . . . . . 1500 psi (10.3 MPa, 103 bar) Maximum Fluid Working Outlet Pressure . . . . . . . . . . . 2500 psi (17.2 MPa, 172 bar) Air Supply Pressure Range . . . . . . . . . . . . . . . . . . . . . . 60-100 psi (filtration required) Fluid Filtration Recommended. . . . . . . . . . . . . . . . . . . .
