How to fix a completely dark display module on a Graco Dispenser?
If the display module on your Graco Dispenser is completely dark, start by verifying that the rear AC power switch is turned ON. If it is on, check the fuse and replace it if it's blown. A loose connection could also be the cause, so tighten the 5-pin cable on the display module. If none of these steps work, the display module may be faulty and need replacement.
What does error code E24 mean on Graco PR70 Dispenser?
If you receive an E24 Improper Calibration Error on your Graco Dispenser, it indicates that the machine's calibration is invalid, preventing the requested shot from being executed. To resolve this, correct the calibration on the machine.
Why is the material dispensed from my Graco Dispenser not the correct weight?
If the Graco Dispenser is dispensing material that is not the correct weight, first, recalibrate the machine if the specific gravity of the materials has changed or if the air pressure has changed since the last calibration. Also, ensure there is enough material in the tanks, filling and priming as needed. If there's a slight obstruction in the mixer, replace it and prime the machine. Finally, inspect the check valve for malfunctions, cleaning or replacing it if necessary, and replace the piston if it's worn or broken.
What to do if my Graco PR70 is dispensing off ratio?
If your Graco Dispenser is dispensing off ratio, start by checking the tank levels and adding material if necessary. Ensure the tank ball valve is open and prime the machine. If the machine is out of phase, rephase it. Also, check the valve for any malfunctions, and clean or replace it as needed. Finally, replace the piston if it's worn or broken.
What to do if the piston is stalled on my Graco Dispenser?
If the piston in your Graco Dispenser is stalled, reconnect the input air line to the machine and increase the air pressure regulator adjustment. Replace the static mixer, and consider incorporating a purge timer or decreasing its delay to prevent mixer blockage. Readjust the Open Dispense Valve (ODV) setting to occur sooner. Remove, clean, and replace any blocked check valves. If these steps don't resolve the issue, the air cylinder may have failed, requiring you to remove and reinstall the air cylinder parts as necessary.
How to fix a completely dark display module on Graco PR70?
If the Display Module of your Graco Dispenser is completely dark, first verify that the rear AC Power switch is ON. If it's on and the display is still dark, replace the machine fuses. Check and tighten the 5-pin cable on the Display Module to ensure a secure connection. If the problem persists, the Display Module may be faulty and require replacement.
How to fix a stalled piston in Graco PR70?
If the piston in your Graco Dispenser is stalled: * Check if the input air is reduced or removed. Reconnect the input air line to the machine and increase the air pressure regulator adjustment. * The mixer could be blocked. Replace the static mixer, and incorporate a purge timer or decrease the purge timer delay to prevent future blockages. * The Open Dispense Valve (ODV) adjustment might be too late. Readjust the ODV setting to occur sooner. * A check valve might be blocked. Remove, clean, and replace the check valve. * There might be an air cylinder failure. Remove the air cylinder and reinstall the air cylinder parts as necessary.
What to do if there is a material leaking from the pump rear seal on my Graco PR70?
If there's significant material leaking from the pump rear seal of your Graco Dispenser, it's likely due to a worn pump shaft. To fix this, remove the pump shaft assembly and reinstall a rear pump rebuilt kit.
What causes a piston to stall in a Graco PR70 and how to fix it?
If the piston on your Graco Dispenser is stalled, it could be due to several reasons. First, check if the input air is reduced or removed; reconnect the air line and increase the air pressure regulator adjustment. A blocked mixer can also cause this, so replace the static mixer and consider using a purge timer to prevent future blockages. An improperly adjusted Open Dispense Valve (ODV) might be the issue, so readjust the ODV setting. Additionally, a blocked check valve can cause the piston to stall, so remove, clean, and replace it. Finally, an air cylinder failure could be the cause, so remove and reinstall the air cylinder parts as needed.
What to do if my Graco PR70 Dispenser is not dispensing the correct amount of material?
If the Graco Dispenser isn't dispensing material, or the amount is incorrect, there might be several reasons. First, ensure the tank ball valve is open. Next, check if the tank is empty or clogged. If not, there may be air in the material, so prime the machine to remove it. A malfunctioning check valve may also be the cause; try removing, cleaning, or replacing it. Lastly, a worn or broken piston can cause this issue, so remove and replace the piston if necessary.
