11. Troubleshooting
1. Insufficient inlet pressure
2. Electrical Fault
3. Moist or contaminated CMS
4. Too high air consumption
5. Excessive inlet air temperature
6. Insufficient purge air
7. Exhaust silencer blocked
1. Adjust inlet pressure settings. (check rating plate).
2. Ensure the power is on and the generator display panel is
illuminated; check the generator is cycling correctly.
3. Eliminate the cause of contamination. Check external inlet
filtration (inc. Water separator) for failed auto-drains or
condensate build up. Replace inlet AMT dryer cartridges
(where fitted) & CMS – do not re-use
4. Ensure the performance of the generator matches the
system and required N2 outlet delivery.
5. Check against technical specification (Remove heat
source).
6. Consult service personnel to adjust settings.
7. Replace silencer/muffler & Consult service personnel if
problem pirsists.
Poor N2 purity or
product performance
Problem Caused Problem Solution
8. Controller not functioning correctly
9. Controller not illuminated
10. Insufficient inlet pressure
11. Failure to de-pressurize when
cycling
12. Outlet flow stops
8. Ensure the controller is powered; check the on screen
column status to ensure it is powering the solenoid valves.
9. Check power to unit & fuse.
10. Inlet pressure = min 88psig (6barg). If not adjust inlet
pressure settings (check rating plate).
11. Solenoid valve not functioning correctly; if there is power
to the coil, replace valve. A correctly working valve outputs an
audible click when it energizes.
12. Check inlet air supply, purity valve & N2 purity.
(check alarm status)
Failure of generator
to cycle
13. Failure to initialize Generator
14. Erratic air flow from exhaust
13. Switch off and restart generator. Ensure generator is
pressurized before powering it to allow generator to initialize
before commencing operation.
14. Faulty or damaged valve; service required.
Constant
depressurization
Reference to known misuse
• Opening the inlet valve too quickly
Valve should be opened slowly allowing the pressure to build up gradually.
• Inlet/outlet head pipe
Pipe diameter too small or pipe work unsupported.
Inlet pipe work from low point in system, allowing bulk water to collect and enter generator.
• Electrical controller
Incorrect fuse fitted or fuse blown. Check the main I.E.C Connection for fuse (see page 16).
• Additional Items
Use of non-authorized components.
Untrained / unauthorized maintenance / installation personnel used.
Increase in nitrogen consumption without relation to the flow capacity of the product.
Purging the product with cleaning agents that could damage the components or the CMS.
Covers removed or loose during operation.
Failure to carry out a service when indicated by the product.
