332564B

Important Isocyanate (ISO) Information

Important Isocyanate (ISO) Information

Isocyanates (ISO) are catalysts used in two component materials.

Isocyanate Conditions

Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates.

Read and understand material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventilation in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for everyone in the work area.

To prevent contact with isocyanates, appropriate personal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Keep Components A and B Separate

Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination:

• Never interchange component A and component

B wetted parts.

• Never use solvent on one side if it has been contaminated from the other side.

Moisture Sensitivity of Isocyanates

Exposure to moisture (such as humidity) will cause

ISO to partially cure; forming small, hard, abrasive crystals, which become suspended in the fluid.

Eventually a film will form on the surface and the ISO will begin to gel, increasing in viscosity.

NOTICE

Partially cured ISO will reduce performance and the life of all wetted parts.

• Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere.

Never store ISO in an open container.

• Keep the ISO pump wet cup or reservoir (if installed) filled with appropriate lubricant. The lubricant creates a barrier between the ISO and the atmosphere.

• Use only moisture-proof hoses compatible with

ISO.

• Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.

• Always lubricate threaded parts with an appropriate lubricant when reassembling.

NOTE: The amount of film formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the temperature.

Changing Materials

NOTICE

Changing the material types used in your equipment requires special attention to avoid equipment damage and downtime.

• When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.

• Always clean the fluid inlet strainers after flushing.

• Check with your material manufacturer for chemical compatibility.

• When changing between epoxies and urethanes or polyureas, disassemble and clean all fluid components and change hoses. Epoxies often have amines on the B (hardener) side. Polyureas often have amines on the A (resin) side.

Pressure Relief Procedure

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

With Color Change

NOTE: The following procedure relieves all fluid and air pressure in the system.

1. Turn off the supply pumps. Open the drain valve on the supply line fluid filter to relieve pressure in the supply lines. Do this for each color.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the

Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

Without Color Change

NOTE: The following procedure relieves all fluid and air pressure in the system. Use your control interface to issue the necessary commands to your system.

1. Turn off the supply pumps. Open the drain valve on the supply line fluid filter to relieve pressure in the supply line.

2. Command the system to Standby. Trigger the spray device to relieve pressure.

3. Flush the remote mix manifold and spray device.

See

Flush Mixed Material, page 22

.

4. Shut off the solvent supply pump. To relieve pressure, command the system to Purge and trigger the spray device. When the pressure is relieved, command the system to Standby to avoid getting a Purge Incomplete alarm.

5.

If pressure remains in the solvent line between the solvent supply pump and the solvent valve:

• VERY SLOWLY loosen a fitting to relieve pressure gradually.

• Loosen the fitting completely.

If using an electrostatic gun, shut off the electrostatics before flushing the gun.

2. Trigger the gun to relieve pressure. From

Maintenance Screen 4 on the ADM, check the box in the field labeled Gun for each color in the system.

3. Command the system to Purge. Hold the gun trigger open after the solvent valve shuts off to relieve all pressure.

4. Set the system to Recipe 0 to flush the pumps and to purge to the spray device. When flushing is complete the system will go to Standby.

5. Shut off the solvent supply pump. Set the system to Recipe 0 to flush solvent from the pumps and to purge to the spray device. Command the system to Standby after just a couple of seconds, to avoid getting a Purge Incomplete alarm.

6.

If pressure remains in the solvent line between the solvent supply pump and the solvent valve:

• VERY SLOWLY loosen a fitting to relieve pressure gradually.

• Loosen the fitting completely.

7. Verify on the ADM Home Screen that neither pump is showing any pressure.

NOTE: If pressure remains in the solvent line between the solvent supply pump and the solvent valve, VERY SLOWLY loosen a fitting to relieve pressure gradually.

Prime and Fill the System

NOTE: See

Run Mode Screens, page 58 , for further

screen information, if needed.

NOTE: You must prime the input lines to the pumps or the inputs to the color change valves before priming the pump and filling the entire system.

1. If using an electrostatic gun, shut off the electrostatics before filling the lines.

2. Adjust the main air pressure. To ensure proper operation, set the main air pressure as close to

100 psi (0.7 MPa, 7.0 bar) as possible. Do not use less than 85 psi (0.6 MPa, 6.0 bar).

3. If this is the first time starting up the system, or if lines may contain air, purge as instructed under

.

Flush the System, page 23

The equipment was tested with lightweight oil, which should be flushed out to avoid contaminating your material.

4. If the system is powered down, press on the

ADM. Make sure that the system is in Standby mode.

5. Verify that the recipes and the flush sequences are programmed correctly by checking the


and the

Flush Screen, page 73 .

6. Enable the manual override on System Screen 5.

7. Go to the

Fill Screen, page 63 .

8. Select the desired color to load. Press the Prime

Pump key . The color will load the pump through the color stack and out the outlet stack dump valve.

NOTE: In a single color system, skip step 7 and prime the pump out to the gun.

9. Press the Fill Line key to run color out to the remote mix manifold. The pump will run until you press the Stop key to stop the pump.

10. Trigger the gun into a grounded reservoir or purge receptacle until the line is full, then press the Stop key .

11. Repeat for all material lines.

20 332564B

Spraying

To spray in a multiple color system, also see

Multiple Color Systems, page 87

.

NOTE: See

Run Mode Screens, page 58 , for further

screen information, if needed.


1. Command the system to Mix. The system will load the correct mixed material volume.

NOTE: The system will automatically run a Mix

Fill if the recipe is not currently loaded into the system. The Mix Fill volume calculation includes the remote mix manifold volume and the mixed material hose volume. The mixed material hose volume is determined by the gun hose length and diameter entered in

System Screen 3, page 69 ,

and the remote to mix hose length and diameter also entered in

System Screen 3, page 69

.

2. Adjust the flow rate by changing the target pressure (in Pressure Mode) or the target flow rate (in Flow Mode) on the Spray Screen or through the PLC. The fluid flow rate shown on the

Spray screen is the combined total of component

A and B out of the spray device.

NOTE: If spray pressure is adjusted at the ADM while spraying, it is not saved in the recipe until the system is put in Standby. This changes the pressure in the desired recipe.

3. Turn on atomizing air to the gun. Check the spray pattern as instructed in your spray gun manual.

NOTICE

Do not allow a fluid supply tank to run empty.

This can damage the pumps and lead to the proportioning of fluid and air that meets the ratio and tolerance settings of the equipment. This can further result in spraying uncatalyzed or poorly catalyzed material.

332564B 21


Purging

To purge one color and fill with a new color, see

Color Change, page 87 .

Flush Mixed Material

There are times when you only want to purge the remote mix manifold and the spray device, such as:

• end of potlife

• breaks in spraying that exceed the potlife

• overnight shutdown or end of shift

• before servicing the remote mix manifold, hose or gun.

1. Command the system to Standby.

2. If you are using a high pressure spray device or an electrostatic gun, shut off the atomizing air.

3. Trigger the spray device to relieve pressure.

4. Set the solvent supply pressure regulator at the lowest pressure possible. Generally a setting of 25–50 psi (0.18–0.35 MPa, 1.8–3.5 bar) is sufficient.

5. Command the system to Purge A or Purge B.

Trigger the spray device into a grounded metal pail until the purge sequence is complete. When done purging, the system automatically switches to Standby mode, signalling the spray device to stop spraying.

6. If the system is not completely clean, repeat Step

5.

NOTE: For optimal efficiency, adjust purge sequence times so only one cycle is required.

7. Trigger spray device to relieve pressure.

8. Adjust the solvent supply regulator back to its normal operating pressure.

NOTE: The remote mix manifold and gun remain full of solvent after purging.

To reduce risk of fire and explosion, if using an electrostatic gun, shut off the electrostatics before flushing the gun.

22 332564B


Flush the System

To avoid fire and explosion, always ground equipment and waste container. To avoid injury from splashing, always flush at lowest possible pressure.

Follow this procedure before:

• the first time material is loaded into the equipment

• servicing

• shutting down equipment for an extended period of time

• putting equipment into storage

Operation Using a Programmable Logic Controller (PLC)

Operation Using a Programmable Logic Controller

(PLC)

Network Communications and

Discrete I/O

The ProMix PD2K Automatic system does not use a Booth Control module. Instead, it uses Network

Communications and has optional Discrete I/O features to drive the system remotely.

Some automation control elements of the

ProMix PD2K can be driven by a discrete input

or

network communications. These options need to be configured at the ADM (see

System Screen 5, page 71 ). The following features

can be set to ‘Discrete’ or ‘Network’:

• Flow Control – Means of adjusting the control set point (see Flow Control Set Point below).

• Gun Trigger – Means of signaling the ProMix PD2K when the spray device is triggered.

NOTE: The Manual Override check box enables a user to operate the system before the automation

(PLC) is available. Manual Override can be used to run all functions of the system if a proper gun trigger signal is provided. It is not intended to be the main mode of control. Graco recommends that Manual

Override be disabled during normal operation to avoid driving the system in a way that conflicts with the automation sequence.

Discrete I/O

The ProMix PD2K does not supply power for

Discrete I/O. A clear understanding of these inputs is necessary to properly integrate the ProMix PD2K with the PLC or networking device. Input and output connections are made at the Discrete I/O terminal strips on the Enhanced Fluid Control Module (EFCM) inside the control box.

Table 3 and Figure 2 show where discrete I/O connections are made on the ProMix PD2K.

Digital Inputs

• Safety Interlock: This normally open contact works like a soft emergency stop button. If the ProMix

PD2K reads the input as CLOSED it interrupts system operation and removes power from the pumps regardless of the current operating mode.

If the input is read as OPEN, the system operates normally

NOTE: This digital input is always enabled.

Do not toggle this input to put the system into

Standby mode.

• Gun Trigger: This normally open (maintained) contact provides a signal to the system to indicate whether or not a spray device is triggered. This input provides timing for alarm functions and also drives the flow control algorithm. If the input is

OPEN the system operates as though the spray device is off. The input must be maintained

CLOSED to signal that the spray device is triggered.

NOTE: The Gun Trigger discrete input must be enabled via Configure Screen 5 on the ADM. If it is set to ‘Network’ the discrete input is ignored and the spray device trigger signal is handled via the network communications.

If enabled, it is imperative that this signal be sent any time the spray device is triggered. Without the signal, the flow control features will not work.

Analog Inputs

Flow Control Set Point: When enabled, this 4-20mA signal input is used to set and adjust the operating flow control set point. The ProMix PD2K scales the set point linearly from 0 to the Max Set Point setting

(see


).

Examples

,

• In Flow Control Mode: If the Max Set Point is 500 cc/min, a 4mA signal is 0 cc/min and a 20mA signal is 500 cc/min.

• In Pressure Control Mode: If the Max Set Point is

500 psi, a 4mA signal is 0 psi and a 20mA signal is 500 psi.

NOTE: The Flow Control discrete input must be enabled via Configure Screen 5 on the ADM. If set to ‘Network’ the discrete input is ignored and set point adjustment is handled via the network communications.

ProMix PD2K Network Inputs

The ProMix PD2K Network Inputs are Write-Read capable, but should be treated as outputs from a PLC or other networking device. These registers allow the user to control system operation and configure system settings remotely. Invalid values (i.e. out of bounds or not consistent with system configuration) will be ignored by the ProMix PD2K. All values must be written as integers. Floating point numbers are not supported.

Do not rely on these registers for Read status, other than to confirm data that has been written and accepted.

NOTE: The PD2K system does not refresh the values for these registers. At power up all input registers initialize to invalid values.

INPUT REGISTER 00: System Mode Command

The System Mode Command register accepts a number that represents a command to the PD2K system to initiate a particular operation. Some operation modes may be initiated only under certain conditions (see

Figures 5 – 9 for details).

Description

The system takes no action.

The system powers on or powers off the pumps.

The system stops all current operations and turns off power to the pumps.

The system initiates a recipe change. (See also Register 7.)

The system fills the mix manifold and gun with material at ratio for a valid recipe.

The system initiates a mix/spray cycle.

The system purges only Material A out through the gun.

The system purges only Material B out through the gun.

The system puts all active pumps into Standby mode.

36 332564B


INPUT REGISTER 01: Pump Flush Sequence/Prime

Material Selection

The Pump Flush Sequence/Prime Material Selection register is used in conjunction with the Flush/Prime

Pump Command register (see INPUT REGISTER 02 below) to independently prime or flush an inactive pump.

• Write a value between 1 and 5 if flushing a pump.

• Write a value between 1 and 30 if priming a Color pump.

• Write a value between 31 and 34 if priming a

Catalyst pump.

NOTE: It is important that the user know which material is assigned to each pump. An invalid selection will be ignored by the ProMix PD2K.

INPUT REGISTER 02: Flush/Prime Pump Command

The Flush/Prime Pump Command register is used in conjunction with the Pump Flush Sequence/Prime

Material Selection register (see INPUT REGISTER

01) to independently prime or flush an inactive pump.

The desired pump MUST be in Standby mode.

Confirm by reading the corresponding Pump Status output register (see OUTPUT REGISTERS 01 – 04).

If an invalid Flush Sequence or invalid material number is written to the Pump Flush Sequence/Prime

Material Selection register then the Flush/Prime command will be ignored. The user must know what material is assigned to each pump. (See

Color Change Kits Instruction Manual 332455 for color/catalyst pump mapping.)

NOTE: If two pumps are currently mixing and an inactive pump is commanded to flush or prime it will continue its operation to completion without affecting the system mode status. When the mixing operation is complete, the system status will reflect Standby mode while the flushing/priming pump completes its operation.

INPUT REGISTER 03: Mix (Pump 1) Control Set

Point

The Mix Control Set Point register is used to set and adjust the mixing fluid control set point. It also is used as the fluid control set point for pump 1 when running a 1K recipe. It can be changed at any time, and the system will immediately adjust to the new set point.

• If the system is configured for Flow Control this value can be set between 5 and 1600 cc/min for a

2K recipe, and between 5 and 800 for a 1K recipe.

See Fluid Control on


.

• If the system is configure for Pressure Control this value can be set between 0 and the maximum pump pressure in PSI. See Fluid Control on


.

NOTE: The Flow Control must be configured to

‘Network’ via System Screen 5 on the ADM. If set to ‘Discrete’ this register is ignored and set point adjustment is handled via the discrete input. See

Analog Inputs, page 25

.

INPUT REGISTER 04: Pump 2 Control Set Point




INPUT REGISTER 07: Go to Recipe Number

The Go to Recipe Number register is used as a queue for the next recipe to be loaded when a recipe change is initiated. A number between 0 and 60 can be written to this register. However, a recipe must be enabled via the ADM before it can be loaded. See

Recipe Screen, page 72 .

NOTE: Writing to this register does not trigger a recipe change.

See

Color Change Sequence, page 44 .

332564B 37


INPUT REGISTER 08: Clear Active Alarm

The Clear Active Alarm register is used to acknowledge an alarm remotely so that the system may resume operation. Be sure that the alarm condition has been alleviated. Write a 1 to this register to acknowledge the latest active alarm. If more than one alarm is currently active only the most recent alarm will be acknowledged. A repeated write should be performed to clear any remaining active alarms. See figure 9.

(See

System Errors, page 88

for more information on clearing alarms.)

NOTE: This register is not polled by the ProMix

PD2K. An alarm is cleared only when a value of ‘1’ is written to this register. It is recommended that the automation reset this register by writing a 0 to it at all other times to avoid inadvertently clearing an alarm.

INPUT REGISTER 09: Job Complete

The Job Complete register is used to log the current job remotely. Write a ‘1’ to the register to command the ProMix PD2K to flag a job complete.

(See

Usage Screen, page 64

for more information on

Job Logs and Job Complete.)

NOTE: This register is not polled by the ProMix

PD2K. A job is logged only when a value of ‘1’ is written to this register. It is recommended the automation reset this register by writing a 0 to it at all other times to avoid inadvertently logging a job.

INPUT REGISTER 10: Gun 1 Trigger

The Gun 1 Trigger register is used to signal the

ProMix PD2K when the automatic spray device is triggered. This signal should be sent any time the spray device is triggered. The state of this register provides timing for alarm functions and also drives the flow control algorithm.

NOTE: If enabled, it is imperative that this signal be sent any time the spray device is triggered. Without it the flow control features will not work.

• Write a value of ‘1’ to signal that the gun is triggered.

• Write a value of ‘0’ to signal that the gun is NOT triggered.

NOTE: This register is used only if the Gun Trigger is set to ‘Network’ via System Screen 5 on the ADM.

If it is set to ‘Discrete’ this register is ignored and gun trigger is handled via the discrete input. See

Digital Inputs, page 25 .

NOTE: Because timing is so critical for flow control Graco recommends that users provide a discrete input to minimize latency effects.

Network Communication - Dynamic Command Structure (DCS)

Dynamic Command Description

The Dynamic Command Structure (DCS) is used to 1) access data that requires some form of argument(s) or 2) consolidate data that requires multiple registers. The DCS uses a static set of network communication input and output registers (see

Network Input Data Map (Write/Read), page 40

and

Network Output Data Map (Read Only), page 33 .

Use the following sequence for the DCS.

1. Write the appropriate command arguments to INPUT REGISTERS 14 – 20. These commands may be written sequentially or sent all at once.

2. Once all arguments have been passed, write the command ID to INPUT REGISTER 21.

3. The ProMix PD2K will respond to a valid command by writing a 2 (Acknowledge) to OUTPUT REGISTER

28.

4. The ProMix PD2K will write appropriate return values to OUTPUT REGISTERS 29 – 36.

Flow Control System

Overview

Flow control is an optional feature that precisely regulates the flow of material to an automatic spay device, to help ensure adequate coverage and avoid sags or runs in the finish coat. The ProMix PD2K system can control fluid flow by directly controlling the proportioning pumps. The pumps accurately dispense a fixed volume of fluid during each stroke.

For this reason, the flow rate of a given pump is directly proportional to the velocity of the pump. As long as the gun is open and the system is stable, flow control is the most effective method for controlling flow rate.

The flow control system relies on two main inputs for controlling flow rate: Gun Trigger and Control Set

Point.

NOTE: These inputs are timing critical. Graco recommends that users wire them discretely to the controller.

Alternatively these two inputs can be driven by the network communications, but latency could be an issue for systems requiring precise timing.

See

System Screen 5, page 71 , for more details on

configuring these options for ‘Discrete’ or ‘Network’.

NOTE: Flow control cannot be selected with a manual gun system.

Normal Flow Control

The ProMix PD2K will directly control the speed of the pump(s) to the programmed flow control set point to maintain accurate flow rate and ratio. The flow control set point is set by Network Communications or the Discrete Input.

The system is considered to be stable when the pressure readings do not fluctuate and the flow rate is maintained. While the system is considered stable it will store (“learn”) the associated pump pressures to a table that is used if the gun trigger signal is lost or removed.

Pressure Control

When the gun trigger signal is removed the system automatically switches to pressure control mode to avoid over pressurizing the fluid lines and to allow smooth transition to flow control if the gun trigger signal returns. It also works to maintain a consistent flow rate even though it has transitioned to pressure control mode if the gun trigger signal is inadvertently lost.

Gun On/Off Prediction

The pressure table also is used to predict if the gun has been turned on or off (without a change to the gun trigger input). The flow control system continually monitors the desired outlet pressure compared to the actual outlet pressure. If the actual pressure remains

50% higher than the desired pressure for longer than

10msec, then the system predicts that the gun trigger has been released. If the actual pressure drops below the desired pressure longer than 10msec, then the system predicts that the gun has been triggered.

The gun on/off prediction is used in the flow control algorithm to prevent the fluid pressure from becoming too high or too low due to a system disturbance. For example, if a gun off prediction occurs while the gun trigger input is high, the system will begin to control to the pressure value last stored in the pressure table for the current flow set point.

System Startup and Defaults

The pressure table is stored in volatile memory, so the table values will be lost after a power cycle of the

ProMix PD2K controller. This issue is not significant because the system generally is able to recalculate new pressure table values within a few seconds

(depending on the stability of the fluid system).

Figure 29 System Screen 2, in Standby Mode

Mix Pressure Tolerance

The pressure of one component must be within a percentage (±) of the pressure of the other component during spray or mix. Set the desired Mix

Pressure Tolerance in this field. The default is 75%.

Stall Test Pressure

Set the minimum stall test pressure. The setting should be approximately 50 psi (0.35 MPa, 3.5 bar) higher than the highest inlet pressure.

Pump Stall Test

Set the duration for the pump stall test. See

Calibrate Screen 1, page 77

.

Maximum Leak Rate

Enter the maximum allowable leak rate for a pump stall test.

Mix Idle Timeout

The Gun Trigger Input signals that the device is triggered. If you are not using a gun trigger signal, the system does not know if the spray device is spraying. If a pump failed you could spray pure resin or catalyst without knowing. This should be caught by the Mix No Flow Timeout; the default is 5 seconds.

The Mix Idle Timeout will trigger Idle mode, which will run a pump stall test to check for leaks, then put the pumps in Standby (holding their current position) after the designated period of time. Enter the desired

Mix Idle Timeout in this field.

See


.

Mix No Flow Timeout

The Gun Trigger Input signals that the gun is triggered. If the Gun Trigger Input indicates that the gun is triggered, but there is no fluid flow through a pump, you could spray pure resin or catalyst without knowing. The Mix No Flow Timeout will cause the system to shutdown after the designated period of time. The default is 5 seconds. Enter the desired shutdown time in this field.

See


.

Low Flow Tolerance

This field is active in systems set to Flow Control.

The system will detect if the flow rate falls below a designated percentage of the target flow rate. Set that percentage in this field. For example, you might want the system to time out if it detects a flow rate that is 10 percent of the target, rather than waiting until a no flow timeout occurs.

Low Flow Timeout

The low flow timeout causes the system to shut down after the designated period of time if the flow rate continues to be at or below the low flow tolerance set in the previous section. The default is 5 seconds.

Enter the desired shutdown time in this field.

System Errors

System Errors

System errors alert you of a problem and help prevent off-ratio spraying. There are three types:

Advisory, Deviation, and Alarm.

An Advisory records an event in the system, and will clear itself after 60 seconds.

A Deviation records an error in the system but does not shut down the equipment. The deviation must be acknowledged by the user.

If an Alarm occurs, operation stops.

If any of the three types occur:

• Alarm buzzer sounds (unless in silent mode).

• Alarm popup screen shows the active alarm code

(see

Error Codes, page 89

).

• Status bar on the Advanced Display Module shows the active alarm code.

• Alarm is saved in the date/time stamped log.

To Clear Error and Restart

NOTE: When a deviation or alarm occurs, be sure to determine the error code before resetting it. If you forget which code occurred, go to the

Errors Screen, page 65

, to view the last 200 errors, with date and time stamps.

If an alarm has occurred, correct the cause before resuming operation.

To acknowledge a deviation or clear an alarm, press on the Advanced Display Module. Users also may acknowledge and clear errors via a network device.

Gun Trigger Input Function

The Gun Trigger Input signals the controller when the gun is triggered. The gun icon on the Advanced

Display Module shows spray when the Gun Trigger

Input is activated.

If a pump fails, pure resin or catalyst could spray indefinitely if the unit does not detect the condition and intervene, which is why the Gun Trigger Input is so important.

If the unit detects through the Gun Trigger Input signal that the gun is triggered, yet one or both of the pumps are not running, a Flow Not Detected Alarm

(F8D1) occurs after 10 seconds (default) and the system goes into Standby.

This is a manual stall test failure when the pump cannot build pressure to the target

“Stall Test Pressure.”

Will fault after 30 seconds.

Cause

System has a leak or open valve that is allowing unrestricted flow.

Pump is cavitating, cycling without restriction.

Viscosity of material is too thin for nozzle size.

System pressure or

Flow Setpoint is too high (causing the pump to work too hard).

No material in the pump or line.

Leak in the system.

Solution

Inspect system for leaks.

Verify that the pump is being supplied with material.

Reduce nozzle size to create more restriction.

Reduce paint pressure to lower the flow rate.

Reduce the pressure or the Flow Setpoint.
