Troubleshooting - Parker BAM10 Mode D'emploi

6 Troubleshooting

In the unlikely event that a problem occurs on the equipment, this troubleshooting guide can be used to identify the probable cause and remedy.
Troubleshooting should only be attempted by competent personnel. All major repair, and calibration work should be undertaken by a Parker
domnick hunter trained, qualified and approved engineer.
Fault
Poor dewpoint identified by water in the
downstream piping and equipment
High pressure drop resulting in low pressure
gauge readings or intermittent operation of the
downstream equipment.
Interruption of the air supply downstream
leading to a rapid loss of system pressure.
20
Probable Cause
Dryer is operating outside of its sizing criteria
Bypass valve is open.
Dryer has recently been started.
The condensate is not being drained.
Regeneration column pressure > 350mbar.
Timer malfunction.
Valve malfunction.
Desiccant is approaching the end of its useful life.
The pre / after filtration is approaching the end of its
operational life.
The dryer is being overflowed or is operating at a
reduced system pressure.
An isolation valve is partially closed.
Pressure loss from the system.
The dryer tripped due to power supply interruption to
the dryer.
The compressor tripped due to power supply
interruption to the compressor.
Isolation valve closed
Compressor switched off.
Fault shutdown event.
Remedy
Check actual inlet parameters and environmental conditions
against the values quoted at the time of sizing.
Check bypass valve is fully closed.
Allow time for the system to "dry down"
Check the condensate drain(s) for faults.
Check the drain hoses are free from kinks and obstructions.
Ensure that the drain isolation valves are fully open.
Replace the exhaust silencers.
Contact a PdhFNS approved service agent.
Contact a PdhFNS approved service agent.
Contact a PdhFNS approved service agent.
Check and replace.
Check actual inlet conditions against the values quoted at
the time of sizing.
Check the position of all the isolation valves.
Check the system for leaks.
Ensure that the drain cocks and pressure relief valves are
closed.
Check that the dryer "POWER ON" indicator is illuminated. If
it is not check the isolator and fuses.
Check that the compressor "POWER ON" indicator is
illuminated. If it is not check the isolator and fuses.
Check the position of the isolation valves.
Check the compressor.
Check the dryer fault indicators.
