Note: If equipped will nitrogen, a nitrogen gas supply line may connected to the atmospheric ball valve. 6. Open the material tank fill port ball valve seen in the Material fill position illustration. Material will vacuum load into the tank. 7. From the CONTROL panel, watch for the HIGH indicator for the corresponding material tank. If your machine is equipped with no high level sensor then do not fill the tank passed ½ to 2/3 of the tank capacity. Material Tank Fill Port Ball Valve Open 8. Close the material tank fill port ball valve when the tank is full. This is seen when the HIGH indicator are illuminated. 9. Allow material to vacuum and agitate until it is fully degassed. Then, close the vacuum pump ball valve. Turn off the vacuum pump. Atmospheric Bleed Ball Valve Open Vacuum Ball Valve Closed Atmospheric Position Illustration 10. Open the atmosphere bleed ball valve. 6

7 NOTE: Some machine may have nitrogen gas or pneumatic pressure supply lines connected to the atmosphere bleed ball valve; in this is the case, then, open the atmosphere bleed ball valve and apply 2 to 3 psi, do not exceed the maximum psi rating labeled on the tank. 11. Open the material feed ball valve. NOTE: Skip the next step if the pump and hose are already primed with material. 12. At initial material loading, or after pump maintenance, do the following: a. Open the material feed ball valve. Allow all air to vent from the pump. b. Close the material feed ball valve. c. Repeat degassing steps to rid the material of the air that vented from the pump. 13. Open all material feed ball valve. NOTE: Repeat the degassing procedure any time you add additional material to the tank or vent air into the tank. 7

8 Gravity Feed Tank A Gravity Feed Tank uses the force of gravity to draw material into the pump. Test all machine features and controls before loading material for the first time. Do not operate machine with material under vacuum. 1. Remove the lid from the material reservoir. 2. Slowly pour or ladle the material into the tank (down the side of the tank wall preferably) to entrap as little air as possible. 3. Allow sufficient time for any air to vent from the pump. 4. Replace and secure the material tank lid, making sure that the vent valves are in the opened position. 8

9 Vacuum Pumps Details: 6.9 CFM Vacuum Pump package with pump mounted on/off switch, inlet chemical trap, outlet oil mist filter, and 1 in. x 120 in. vacuum rated hose and fittings for one tank. The package is designed for vacuum degassing of material in a vacuum rated feed tank. The degassing process helps to assure that dispensed material meets the target properties required for the application. Component List: Oil sealed rotary vane single stage 6.9 CFM vacuum pump with 0.75 HP, VAC or VAC, depending on selection, single phase, 50/60 Hz drive motor, cordset, and pump mounted switch. Pump is rated to obtain a maximum vacuum level of 0.1. Inlet chemical trap with activated carbon filter, sight glass and 1.8 liter capacity prevents froth or spray generated by the degassing process from carrying over to the pump. Trapped liquid level is visible in the sight glass and the hand-tightened drain plug allows easy draining. Outlet mist filter captures oil mist to assure a clean operating environment and meet regulatory requirements. An odor element neutralizes the smell of oil mist and the translucent lower filter allows visual oil level monitoring. Vacuum rated 1 in. x 120 in. hose and fittings are for connection to a vacuum rated feed tank. Operation W hen the oil is degassed, the pump will based out at or near it's published ultimate vacuum. It is helpful to keep a simple log book as eventually the ultimate vacuum will begin to degrade. This is one indication that the oil should be changed. Also, visual inspection of the oil is necessary to ensure pump longevity. If the oil begins to go dark it must be changed. Our application group recommends an isolation valve at the pump inlet with an appropriate vacuum gauge. A summary of operation and technique to base-line the pump include the following. NOTE: See the following image. 1. Change pump oil (necessary to adequately baseline the vacuum pump). 2. Install inlet isolation valve and appropriate vacuum gauge. 3. Close pump inlet isolation valve. 4. Turn on vacuum pump with gas ballast valve full open. 5. Run pump for 1/2 hour to allow pump to warm up (having the gas ballast open allows the pump to heat up faster). 6. Record base vacuum with gas ballast on (baseline with gas ballast open). 7. Close gas ballast valve and record base vacuum (baseline with gas ballast closed). 8. Open gas ballast valve to full on position. 9. Open inlet isolation valve at pump. 9

10 10. Execute process. 11. Once process is complete close inlet isolation valve at pump. 12. Run pump for at least 1/2 hour with gas ballast valve open to full. 13. Check and record pressure after 1/2 hour. Pump should baseline to pressure recorded with gas ballast open. Run longer if needed. 14. Close gas ballast valve. 15. Check and record pressure which should baseline to pressure recorded. 16. Turn off vacuum pump. Inspect oil and record color. Use the attached color chart and guidelines in attached document. 10

11 Electric Agitator Specifications The electric agitator assembly has a 0.5 HP AC electric motor, 30:1 gear reducer, and a shaft/blade assembly. A three position selector switch allows low speed (29 rpm), high speed (58 rpm) or OFF. For materials with a maximum viscosity of 100,000 centipoise and maximum material temperature of 275 F. General Info The Agitator Speed Controller enables/disables the electric agitator and also increases/decreases the tank agitator speed. OFF: The tank agitator is disabled and the material in the tank is not agitated. LOW: The tank agitator is enabled and the material in the tank is agitated at the minimum speed. HIGH: The tank agitator is enabled and the material in the tank is agitated at the maximum speed. 11

12 Pneumatic Drive Agitator The pneumatic drive agitator assembly has a 0.9 HP pneumatic motor, a 27:1 gear reducer, and a shaft/blade assembly. The pneumatic agitator includes a needle valve to adjust rotational speed from 10 to 160 rpm (water thin media). The pneumatic agitator is for materials with a maximum viscosity of 100,000 centipoise and maximum material temperature of 275 F (135 C). 12

13 Drum Feed Kit A drum to drum to pump feed kit consists of hoses, hose clamps, and fittings used to deliver material from the drum to the pump. Test all machine features and controls before loading material for the first time. 1. Close both ball valves on top of the drum. Disassembling the top drum feed piping assembly is done by grasping the brass-colored rings on the cam levers and pulling them away from the piping assembly. 2. With the new material drum in an upright position, remove the 2 NPT cap from the drum and replace it with the threaded end of the large male section (from the old drum). Close the ball valve. 3. Remove the 3/4 NPT cap from the drum and install the provided vent tube. 4. Connect the air dryer to the vent assembly (if required). 5. Close all ball valves. 6. Reconnect the top drum feed piping sections, between the pump inlet and the drum, by inserting the male section into the female section and squeezing the cam levers down snug against the piping.. 7. Install drum on rack. Open the ball valves on the drum material feed line, and the pump material feed line. Open the ball valves common to the vent. 8. Allow minutes for all air to vent from the pump and to the drum. CAUTION: The vent tube must be higher than the material level in a full drum. WARNING: Do not connect any pressure device to the vent tube assembly. 13

14 Accumulator An accumulator feed system is used with high viscosity materials to drive the material into the pump. The 4 in. diameter feed system is equipped with high and low level switches to activate a remote material transfer pump for automatic refill. The transfer pump is stopped when the high level switch indicates the accumulator is full. NOTE: Transfer pump not included. 14

15 Slinger Plate The slinger plate is a flat metal disc secured to the agitator shaft. It is used to spread low viscosity materials via centrifugal force, increasing the material surface area for rapid vacuum degassing. Slinger Plate 15

16 Vacuum Ready Lid with Shower Head This lid is complete with vacuum fittings, vacuum gauge, and shut-off ball valve with shower head. The material handing system for the day tank fills from the bulk feed (supplied by customer) using a vacuum pump (supplied by the customer). The vacuum ready lid is used with high viscosity material that will be pulled thru the shower head creating an umbrella-like stream into the day tank. This process increases the surfaces area of the material. The process is not desirable for low viscosity materials. Shower Head 16

17 Follower Plate The follower plate is a 9 in. diameter polyethylene plate with a handle. The plate rests on top of the material and moves down the tank as material is used, forcing the material into the middle of the tank and preventing cavitation. Follower Plate 17

18 Nitrogen The nitrogen option consists of a nitrogen harness with gauges and regulator. The gauges and regulator need to be connected to a nitrogen bottle. The hose quick disconnect fittings are connect to the mating quick disconnect fittings, on the tank lids. One of the gauges shows the nitrogen pressure from the nitrogen bottle. The other gauge shows the nitrogen pressure being fed to the material tanks through the regulator on the nitrogen harness. A typical blanket pressure should be 1-3 psi. The tank lid has a 5 psi pressure relief valve. This system can also be used for pressure feed systems. WARNING: If used for pressure feed systems, do not exceed the maximum pressure rating of the material feed tank. The nitrogen is used to pressurize the material tanks. This pressurization will place a dry nitrogen blanket on the surfaces of the materials in the tanks. NOTE: Nitrogen bottle not included. 18

19 Desiccant Dryer The disposable desiccant dryer provides dry make-up air and helps prevent moisture contamination. Operation at Installation a. Remove each of the plastic red caps on the filter elements canister that are in place for each of the A and B side material collection devices. b. Fill in the Installation Date sticker on the filter elements canister for each of the A and B side material devices. c. Replace device when the filter elements in the canister turn purple (see sticker). The filter elements in the canister are blue when new (see sticker). Desiccant Dryer 19

20 Heat Heat Controller Options There are four heat controller options. Each heat controller option provides one heat zone for each heated item in the system. If the system only has heated hoses, then the heat controller option is 2-Zone Low Wattage Heat. If the system has two items to heat and at least one is not a heated hose, the heat controller option is two Standard Heat Control Zones. If the system has four or six items to heat, the heat controller option is four or six Standard Heat Control Zones, as applicable. Tank Heat Options The material tanks should be heated if any of the following functions are needed: Reduced viscosity for better flow or penetration in potted parts Reduced viscosity for faster vacuum degassing Reduced the gel or cure time of the final mixture Reduced viscosity to aid in feeding the metering pump Achieving a consistent temperature where ambient temperature varies and affects mixed material properties Pump Heat Options Heating the pumps is rare. This option should be chosen when the material being pumped crystallizes or becomes highly viscous at or near room temperature. Shroud Heater The shroud heater wraps around the dispense valve to maintaining material temperature through the dispense. 20

21 Twindispense The Twindispense style injection block is used for applications where line pressure is not maintained between cycles. 21

22 Hydracheck Features: Applications requiring dampen (smooth) Dispense Material Flow. Description: The Hydracheck unit consists of an Oil-filled Cylinder, Air Cylinder, Skip Solenoid, Stop Solenoid and Adjustable Needle Valve. When the Air Cylinder Shaft extends, the Shaft will begin to push against the Oil-Filled Piston Rod and the Skip or the Stop Solenoid is actuated, at a rate determined by the Needle Valve setting (approximately when the machine pistons have reached the metering tube openings). Hydraulic fluid is forced through the needle valve in the opposite end of the unit. The Adjustable Needle Valve controls the flow rate of the fluid through this closed-loop circuit. Therefore, the action of the air cylinder piston is completely controlled. Chatter and flutter are eliminated and the Hydracheck compensates for any variation in the power stroke. The Hydracheck unit does not affect the retract half of the machine cycle. Setting Desired set points: The Hydracheck Pressure Regulator is to be set to 65 to 75 PSI (70 typical). This setting is not to be readjusted during the operation. Initially set the Hydracheck Needle Valve adjustment to the Minimum restriction point (Minimum restriction point is a single thread is engaged counter clockwise). Operate the machine, adjusting the Air Pump Pressure to a flow rate higher than the desired Material flow rate. Finally set the Hydracheck Needle Valve adjustment to the desired restriction point creating the desired material flow (Maxim restriction point is all threads are engaged clockwise). Skip Check Function Engaged Utilized in Shot and Operator Control Mode. Smooth Dispensed Material Flow at a consistent rate when External Start is Actuated and Open Dispense Valve Limit Switch is Actuated. Stop Check Function Engaged Utilized in Operator Control Mode only! Mechanically Stop Dispensed Material Flow at Open Dispense Valve Limit Switch point, which then maintains Air Pump Pressure waiting for another External Start. Mechanically Stop Dispensed Material Flow at each point beyond Open Dispense Valve Limit Switch point, which then maintains Air Pump Pressure waiting for another External Start until Retract Limit Switch point is reached. 22

25 Operating Instructions The Series B171-1 Hydro-Check is a precision-built, adjustable, hydraulic resistance unit designed to provide a smooth controlled feed rate on Bellows Air Motors, Drill Press Feeds and other air or manually operated machine elements. The Series B171-1 Hydro-Check is a single acting unit, available with checking action on either forward or reverse stroke for checking loads up to 1200 pounds. (For checking loads up to 3000 pounds, Series B171-2 and B171-3 may be used.) OPERATING PRINCIPLE: The Hydro-Check consists basically, of a checking cylinder (Item 27), checking piston rod (Item 1), adjustable needle valve (Item 34), and a balance cylinder (Item 43). The checking piston rod may be directly attached or linked to a moving machine part. As the piston rod is pulled out, oil in the checking cylinder is forced, by the moving piston, through the transfer tube, through the needle valve, into the rear end of the checking cylinder. On the return or non-checking stroke, the hydraulic oil returns through the piston valve and the unit is ready for another checking stroke. The balance cylinder assembly (Item 43) automatically compensates for the volumetric displacement of the checking piston rod. An indicator rod (Item 42), attached to the balance cylinder piston, indicates the amount of oil in the Hydro-Check. Three grooves on the indicator rod show when and how much oil should be added to maintain correct hydraulic volume. MOUNTING: The Hydro-Check can be operated in any position provided it is mounted directly inline or parallel to the force it is to control. If unit is mounted parallel, the force or power supply should be guided by ways or guide rods to prevent side strain on the Hydro-Check piston rod. The in-line type of mounting is the most desirable type to use on any application. Series B171-1 Hydro-Checks are available with a threaded piston rod guide and lock nut for nose mounting or pivot brackets and rod clevis for pivot mounting CHECKING STROKE ADJUSTMENT: The mechanical linkage to the element being controlled, moving between two piston rod lock nuts, actuates the Hydro-Check. The point at which checking 25

26 action begins is determined by position of the second lock nut (Item 2) on threaded piston rod. Thus, any portion of the full stroke length may be used for checking. The forward piston rod lock nut is used to lock the second in position. The actuating element engages the first lock nut on return stroke to retract the piston rod. The first or innermost piston rod lock nut (Item 21) must be kept at back end or piston rod thread to prevent Hydro-Check piston from bottoming against rear cylinder head. This nut is locked in position with a socket head set screw. CAUTION: Before applying checking load, be sure stroke of Hydro-Check is long enough to prevent power source from bottoming Hydro-Check piston against front head and possibly damaging Hydro-Check. ADJUSTMENT OF CHECKING RATE: Checking Speed is controlled by turning the knurled needle valve knob (Item 34). Rate is reduced as the knob is turned clockwise and increased as it is turned counter-clockwise. LEVEL: Amount of oil in Hydro-Check is indicated by position of balance cylinder indicator rod (Item 42). The position is determined by grooves on the rod. Proper oil level is indicated when, with threaded piston rod extended, the second indicator groove is flush with balance cylinder head. When threaded piston rod is retracted, the third innermost groove should be flush with cylinder head. Oil should be added when groove nearest end of indicator rod becomes flush with face of balance cylinder head, when threaded piston rod is fully extended. If low, contact Graco customer service. 26

27 Customer Signal This items add a 10 ft (3 m) customer signal interface cable and hardware to initiate a start, and retract, and to indicate ready to dispense and cycle complete conditions. The START signal allows the customer to initiate a start signal by providing a dry contact closure between two designated wires on the cable. The RETRACT signal allows the customer to retract the air cylinder. This stops the pumping action from the dispense valve by providing a dry contact closure between two designated wires on the cable. The READY TO DISPENSE signal provides a contact closure between two designated wires on the cable to indicate that the machine is ready to dispense a metered shot. This signal is only activate in SHOT mode. The CYCLE COMPLETE signal provides a contact closure between two designated wires on the cable to indicate that the machine has completed a metered shot. The closure will be held for one second after the cycle is completed and then it will open. This signal is only active in SHOT mode. 27

29 Grease Option The grease option provides a grease fitting shaft seal lubricator for selected pumps and the dispense valve. This includes the pump seal housing with grease cavity, grease fitting, and vent fitting. A grease gun and PTFE based grease is provided. A thin film of the material being dispensed is always left on the metering pump shaft as a result of the reciprocating pump motion. This option is used as a preventative maintenance tool to help prevent the material on the shaft from hardening. Hardened or partially cured material accumulated on the pump shaft can cause premature seal failure and can slow or prevent the pump from cycling.
