Trouble Alerts and Probable Causes
Trouble Alert #1 - Nitrogen Generator in Bypass Mode for 2 hours
Trouble Alert #4 - Excessive Membrane Runtime
Trouble Alert #2 - Air Compressor is Continuously Running
Trouble Alert #3 - Excessive Air Compressor Cycling
Issue:
Bypass Solenoid Valve continuously ON for 2 hours.
Probable Cause:
1. Air compressor power is turned off.
2. Air Tank Outlet Valve (V01) is closed.
3. Filling multiple sprinkler systems at one time.
4. Leak on nitrogen generator air tank or sprinkler system.
5. Blockage in pathway from air tank to nitrogen tank.
6. Low oil level (check oil level switch).
Issue:
Membrane Inlet Air Solenoid (XV01) and Membrane Outlet N
2
Solenoid (XV02)
continuously ON for 30 minutes.
Probable Cause:
1. Leak on nitrogen generator or sprinkler system.
2. Air Compressor Power is turned off.
3. Air Tank Outlet Valve (V01) closed.
4. Membrane Inlet Air Solenoid (XV01) and/or Membrane Outlet N
2
Solenoid (XV02) are blocked, or closed.
5. Instrument Air Regulator (PRV03) is less than 60 PSI.
6. Blockage in pathway from air tank to nitrogen tank.
Issue:
Air tank pressure switch continuously ON for 90 minutes.
Probable Cause:
1. Filling multiple sprinkler systems at one time.
2. Major leak on nitrogen generator (air side).
a. Air Tank Blow-Down (AD01)stuck open.
b. Float valve on filters stuck open.
3. Leak on sprinkler system.
4. Pressure switch needs to be adjusted or replaced.
5. Air compressor not building adequate pressure.
6. Compressor unloader valve located on pressure switch is stuck open.
Issue:
Air tank pressure switch turns ON 10 times in 1 hours.
Probable Cause:
1. Leak on nitrogen generator air tank. Check valve sticking open could cause the leak.
2.
Float valve on filters could also be stuck open.
3. Excess Air Regulator (PRV01) closed.
4. Pressure switch needs to be adjusted or replaced.
5. Filter elements need to be replaced.
6. Membrane Inlet Air Solenoid (XV01) is stuck open.
