Troubleshooting

A cheatsheet of common issues and fixes for your Eclipse Electronic Paintball Marker. For a more complete list of troubleshooting information consult your Markers User Manual.

Electronic Cheatsheet

Symptom Possible Cause Solution
Marker does not fire. Your Marker is not powered up. Power up your Marker.
ASA is not engaged. Ensure the ASA is fully engaged.
Battery charge is flat, very low or of low quality. Replace the battery.
The DWELL parameter is set too low. Increase the DWELL parameter.
The trigger is set-up incorrectly. Adjust trigger so that it fully opens and closes the microswitch.
Breech Sensor is enabled but no paint is in the breech. Fill Loader with paint and check Loader and feedtube for blockages.
The Pilot Valve is not plugged into the PCB. Plug Pilot Valve wire plug into it's port on the PCB.
The PCB is damaged. Replace PCB.
The Pilot Valve is damaged. Replace Pilot Valve.
The Marker is inconsistent. The DWELL parameter is set too low. Increase the DWELL parameter.
Using poor quality paintballs. Use better quality paintballs.
A poor paintball to barrel bore match. Use a better paintball to barrel bore size match.
The inline regulator requires servicing. Strip and clean inline regulator.
Replace o-rings and regulator seal. Poor / inconsistent air supply to the POPS. Use a good quality preset air system.
The Marker is inefficient. Poor Spool performance. Clean and grease rear spool seals. Check condition of spool spring.
A poor paintball to barrel bore match. Use a better paintball to barrel bore size match.
Rate of fire is low and can't be altered. Issues with the loader Try different loader. Replace loader batteries. Check force and sensitivity settings.
The Marker has low velocity on the first shot. The FSDO parameters are set too low to overcome o-ring stiction. Adjust FSD COMP and FSD DLY parameters.
The bolt assembly is dirty or incorrectly lubricated. Clean, re-lubricate and replace the o-rings on the bolt as necessary.
Velocity drop-off during rapid fire. The batteries are poor quality or have insufficient charge. Replace the batteries. Use alkaline or lithium batteries. Always use high quality batteries.
Air system/regulator doesn’t flow fast enough to keep up. Use a good quality preset air system.
The bolt assembly is dirty or incorrectly lubricated. Clean, re-lubricate and replace the o-rings on the bolt as necessary.
Poorly maintained inline regulator. Strip, lubricate and rebuild the inline regulator.
Paintballs breaking in the barrel or the breech. The loader has too high a force feed setting. Adjust the loader to a lower force feed setting.
The ball detents are damaged or missing. Replace the ball detents.
Poor quality paintballs. Use better quality paintballs.
The breech sensor is switched off. Switch on the breech sensor.
A poor paintball to barrel bore match. Use a better paintball to barrel bore size match.
Unseated rubber bolt tip. Reseat the rubber bolt tip.
Missing or damaged rubber bolt tip. Replace the rubber bolt tip.
On power up the marker will not fire. The trigger is permanently depressed. Adjust the trigger until the selected trigger detection method is deactivated when the trigger is released.
Constant high velocity / Unable to lower velocity to desired fps. Output pressure of the preset regulator is too high. Use a preset regulator with an output pressure below 650 psi. Consult the preset regulator manufacturer for possible faults / maintenance requirements.
Although a fresh battery has been fitted, the Marker will not switch on. The batteries have drained on the shelf. Replace with new batteries.
The batteries are fitted incorrectly. Remove the batteries. Gently squeeze the large terminal on the battery connector to reduce its diameter. Reconnect the batteries.
The breech sensor goes into default mode after firing and the display shows that there is a fault with the breech sensor. The light pipes are dirty. Clean the light pipes.
Pocket in the breech is blocked. Remove eye covers and clean the pockets in the breech.
The sensors are out of place. Check alignment of sensors on the main board.
Two or more balls are being fed into the breech. Worn, damaged or missing ball detents. Change the rubber ball detents.
The feed force is too high from the loader. Adjust loader settings/use a lower force loader.
3 audible beeps when switching on. The secondary circuit board is not responding to the primary circuit board. Check that the ribbon cable is connected at both ends.Make sure the orientation of the ribbon cable is correct. Check the ribbon cable for damage. Check the ribbon mounted connectors for paint or water ingress. Check the board mounted connectors for paint or water ingress.
4 audible beeps when switched on. The primary circuit board does not recognise the secondary circuit board. Determine which board is faulty and replace it.
The batteries do not seem to last very long. The batteries are of a low quality. Use alkaline or lithium batteries. Do not use low quality or rechargeable batteries.
Marker is Leaking from the solenoid and/or manifold. The gaskets between the body and the solenoid or the solenoid and the frame are damaged, dirty or missing. Ensure the gaskets are clean and seated correctly. Replace the gaskets if damaged or missing.
Pilot valve and/or manifold are over-pressurised. Check the output pressure of the inline regulator, adjust accordingly. Clean and inspect the inline regulator assembly paying particular attention to the piston o-ring, piston tip and regulator seal. Replace damaged components as necessary.
Damaged or incorrect seals on the solenoid spool. Replace and/or lubricate solenoid spool seals.
Damaged SMC pilot valve. Replace SMC pilot valve.
The Marker leaks down the barrel. Dirty or damaged can o-rings. Clean and lubricate or replace o-rings on the front of the Can.
Dirty or damaged o-rings on the spool. Clean and lubricate or replace the o-rings on the main spool.
Dirty or damaged bolt o-rings. Clean and lubricate or replace o-ring on the back of the Bolt.
Dirty or damaged rear bolt guide o-ring. Clean and lubricate or replace o-ring on the back of the bolt Guide.
Low rate of fire / rate of fire not reaching the ROF cap. The force setting of the loader is too low. Adjust the loader force feed setting.
The breech sensor has detected a fault and has reduced the ROF. Check the position and condition of the breech sensors. Clean or replace the breech sensors as required.
Low constant velocity. The inline regulator output pressure set too low. Increase the output pressure of the inline regulator.
High velocity first shot. The inline regulator pressure is creeping. Strip and clean the inline regulator replacing the piston seal.
The trigger is very "bouncy". Incorrect filter settings. Check that your DEBOUNCE settings suit your trigger set-up.
Trigger pull is too short and the return strength is too low. Consult your User Manual for trigger adjustment guidelines.
