5. Bleed/relief valve6. Flow meter

Note: The level switch assemblies are located inside the tank.



Theory of Operation

The LP90 motor causes the fluid to be drawn from the tank through the flowmeter valve, into the flow meter pipette, and then into the pump inlet. Thefluid exits the pump through a three‐way tee to which a pressure transduceris connected. The fluid then flows through a manifold and shutoff valve to theapplicator, where is it is dispensed onto the product.

A solenoid valve controls the module‐actuating air supplied to the applicator,causing it to open and close at the appropriate times. As the fluid isdispensed from the applicator nozzle, pattern air and nozzle‐cleaning air maybe blown onto the fluid. The pattern air disperses the fluid and thenozzle‐cleaning air keeps the nozzle clean. The actuation of the solenoidvalve is controlled through a pattern controller or other triggering device.

The LP90 system is designed so that the pump operates only when theapplicator is active. During normal operation, the system pressure will rangefrom 0.07-0.20 bar (1-3 psi). If the pressure exceeds 1.4�bar�(20�psi), ableed/relief valve will open to allow fluid to circulate back to the tank. Thepressure transducer provides a current or voltage signal to the parentmachine's control system, allowing the LP90 system pressure to bemonitored.

The LP90 system can operate in the manual or key‐to‐line (automatic) mode.When operating in the key‐to‐line mode, the system automatically adjusts thefluid output as the line speed changes.

Bulk Fill Option

The bulk fill option allows the LP90 tank to be filled automatically from aremote supply. A supply hose is connected to a solenoid‐operated bulk fillvalve located at the top of the LP90 tank. The supply hose is pressurized withfluid and the bulk fill valve is opened when the bulk fill signal contacts on theparent machine's control system are closed.



Installation Use these procedures to install the LP90 system and the applicator.Installation includes:

� unpacking and inspecting the equipment

� installing the system

� installing the applicator

� connecting the PFA tubing

� making the electrical connections

� setting up the bulk fill option (if applicable)

� preparing the system (bleeding air from the lines)

� setting up the key‐to‐line control

Carefully remove the equipment from the shipping containers. Exercisenormal care to prevent equipment damage and use mechanical liftingdevices as appropriate. After unpacking the equipment, inspect it for anydamage that may have occurred during shipping. Look for dents andscratches and make sure all fasteners are tight.

Operation Use these procedures to operate the LP90 system.


WARNING! Allow only personnel with appropriate training and experience tooperate or service the equipment. The use of untrained or inexperiencedpersonnel to operate or service the equipment can result in injury, includingdeath, to themselves and others, and damage to the equipment.

Startup and Shutdown

CAUTION! The system pressure should not exceed 1.4�bar�(20�psi). Refer toSystem Pressure Monitoring later in this section.

1. To start the LP90 system:

a. Apply power to the system.

b. Enable the applicator.

c. Enable the applicator triggering device.

d. Start the production line.

e. If in key‐to‐line mode (Auto On LED illuminated): close the remotecontacts (closed = run) connected to terminals 3 and 4 on theterminal block.

If in manual mode (Hand On LED illuminated): press the Hand Onkey on the motor drive keypad to start the motor and use the up/downarrow keys (��) to adjust the frequency (motor speed) to thedesired setting.

2. To stop the LP90 system:

a. If in key‐to‐line mode: open the the remote contacts (open = stop)connected to terminals 3 and 4 on the terminal block.

If in manual mode: press the Off Reset key on the motor drivekeypad.

b. Stop the production line.

c. Disable the applicator.

d. Disable the applicator triggering device.

e. Remove power from the system.



Flow Rate Monitoring

Follow these steps periodically to check the flow rate to ensure that thedesired amount of fluid is being dispensed. You will need a stop watch toperform this procedure.

1. See Figure 9. Prepare a stop watch to time the fluid drop in the flow meterpipette (1).

2. Record the volume in the flow meter pipette; then simultaneously closethe flow meter shutoff valve (2) and start the stopwatch.

3. When the stopwatch indicates one minute, note the reading on thepipette and subtract the reading from the volume recorded in step 3. Thisis the flow rate in cc/min.

4. If the measured flow rate does not match the desired flow rate, refer toTroubleshooting.

Fluid Level Monitoring

Monitor the level of fluid in the LP90 tank and ensure that fluid will be addedwhen the tank‐low point is reached.

If connected, the level switch will send a signal to the parent machine controlsystem to activate either a tank low signal or a tank high signal. When thetank low signal activates, 0.75 l (0.2 gal) of fluid remain in the tank. Refer toElectrical Installation earlier in this manual to connect the level switch wiringto the parent machine control system. If desired, the tank low signal can beused to activate a bulk fill system.

System Pressure Monitoring

Monitor the system pressure and ensure that the pressure does not exceed1.4�bar (20 psi). The bleed/relief valve is set to open at 1.4 bar (20 psi). If thebleed/relief valve opens, the flow rate at the applicator will change, causingimproper fluid application. The recommended operating pressure range forthe LP90 system is 0.07-0.20�bar (1-3 psi). If the average system pressurestarts to rise, clean the filter. Refer to Filter Cleaning or Replacement underMaintenance.

If connected, the pressure tranducer will send a pressure reading to theparent machine control system or to a remotely located pressure readout(customer‐supplied). Refer to Electrical Installation earlier in this manual toconnect the pressure transducer wiring to the parent machine controlsystem.



Maintenance Use these procedures to properly maintain the LP90 system. Attempting anyother maintenance procedure can result in equipment damage, impropersystem operation, or personal injury.
