How to troubleshoot fluctuating gauge with no fluid flow in Graco TI12552a?
- T
  Tonya SkinnerAug 25, 2025
  If the gauge reading fluctuates with changes to the % Open value but the fluid flow remains constant or absent in your Graco Industrial Equipment, the problem is likely mechanical. This could be due to a restriction or plugged hose, a plugged gun tip, or a fluid regulator failure. To resolve this: * Clear any clogs. * Remove restrictions. * Clean and/or repair the fluid regulator.

What to do if I get a COLOR/CATALYST_FILL_ALARM on my Graco TI12552a?
- M
  Madison NewmanAug 30, 2025
  A COLOR/CATALYST_FILL_ALARM can occur if the system detects no meter pulses, or doesn't detect at least 10cc of material from each side during the Color/Catalyst fill time. Check that the meter cable is connected and clean or repair the meter. Also, ensure the gun, dump valve, or correct color/catalyst valve is open. Finally, verify that the fluid supply isn't exhausted and refill if necessary.

What does OVERDOSE_A/B_DOSE_TOO_SHORT_ALARM mean on my Graco TI12552a Industrial Equipment?
- E
  Emily IngramAug 30, 2025
  An OVERDOSE_A/B_DOSE_TOO_SHORT_ALARM suggests a valve seal or needle/seat leak, or a sampling valve leak. In this case, repair or tighten/replace the valve. It can also be caused by flow meter fluctuations due to pressure pulsations. Check for pressure pulsations by closing all manifold valves, turning on circulating pumps and booth equipment, and seeing if the ProMix 2KS reads fluid flow without any leaks. If necessary, install pressure regulators or a surge tank on the fluid inlets to reduce fluid supply pressure. Also, consider restricting the flow rate through the component B dose valve by adjusting its hex nut if you are running a high mix ratio and a high flow rate.

What causes PURGE_VOLUME_ALARM in Graco Industrial Equipment and how to solve it?
- J
  James CameronAug 29, 2025
  A PURGE_VOLUME_ALARM can occur if the ProMix 2KS solvent flow switch is not activated while purging. Make sure the gun is not shut off and that the solvent flow switch is activated during the purge. The alarm can also appear if the minimum flush volume is set too high, so increase the solvent supply or decrease the minimum volume setting. Finally, check that the color change solvent supply is set up and functional if there are no meter pulses during Color/Catalyst Dump.

How to troubleshoot COMM_ERROR on Graco Industrial Equipment?
- J
  James LiAug 28, 2025
  A COMM_ERROR indicates a communication issue. First, ensure the EasyKey has power. Then, check the connection of the intrinsically safe power cable between the EasyKey and Fluid Station. Also, verify the condition of the fluid control board fuse and replace if necessary. Check the fiber optic cable connections between the EasyKey and Fluid Station, ensuring the cable isn't cut or bent too sharply (smaller than 1.6 in. or 40 mm radius). Clean the fiber optic cable ends with a lint-free cloth. Finally, if all else fails, replace the communication cable.

How to fix DOSE_TIME_A/B_ALARM on Graco TI12552a?
- S
  Shane RollinsAug 27, 2025
  If you're getting a DOSE_TIME_A or DOSE_TIME_B alarm, try these steps: fully trigger the gun if the system is in Mix mode and the gun is only partially triggered. Increase the fluid flow rate or the dose time setting. If the flow meter or cable has failed, or the flow meter is clogged, clean or repair the meter. Ensure that the supply pump is turned on. Check the air lines for leaks and repair or clean/replace the air flow switch.

What to do if I get a RATIO_LOW_ALARM on my Graco Industrial Equipment?
- B
  Brandon BooneAug 27, 2025
  A RATIO_LOW_ALARM indicates there is too much restriction in the system. Check that the system is fully loaded with material, the supply pump’s cycle rate is set properly, the spray tip/nozzle is properly sized and not clogged and that the fluid regulator is set correctly. If the alarm occurs during start up, after purging, restrict gun needle travel to slow down the initial fluid delivery rate until fluid hoses are loaded with material. If the alarm occurred after you were spraying for some time, adjust component A and B fluid supply regulator pressures until they are about equal. Increase air pressure to the valve actuators to 75-120 psi (120 psi is recommended). Ensure there is no dirt or moisture in the air supply and adjust air and fluid pressure.

Why am I getting a RATIO_HIGH_ALARM on my Graco Industrial Equipment?
- D
  davismorganAug 26, 2025
  A RATIO_HIGH_ALARM indicates there may be too little restriction in the system. Here's what you can check: * Ensure the system is fully loaded with material. * Verify the supply pump’s cycle rate is set correctly. * Confirm the spray tip/nozzle is properly sized and not worn. * Ensure the fluid regulator is set correctly. If the alarm occurs during start-up after purging, restrict gun needle travel to slow the initial fluid delivery rate. If it occurs after spraying for some time, adjust component A and B fluid supply regulator pressures until they are about equal. Also, ensure air pressure to the valve actuators is adequate (75-120 psi, with 120 psi recommended) and that there are no restrictions in the solenoid or tubing interrupting valve actuation air.

What to do if I get a potlife alarm on my Graco Industrial Equipment?
- K
  Kylie SmithAug 26, 2025
  If the potlife time has been exceeded for the mixed material, press the Alarm Reset key to stop the audible alarm. Then, purge the system with solvent, fresh mixed material, or perform a color change. You can purge with solvent until the preset purge time is complete, switch to Mix mode and spray the required volume to restart the timer, or perform a color change.
