may create an opportunity to inspect the fan and remove dust or possibly replace
the power supply.
What Actions To Take For Faults
PS A or B 12V High – Abnormal condition, power supply may be defective.
Replace immediately.
PS A or B 12V low – System may be overloaded (if only one power supply) or
may indicate power supply failure.
PS A or B 24V High – Abnormal condition, power supply may be defective.
Replace immediately.
PS A or B 24V low – System may be overloaded with active receivers. If using
more than 20 active receivers with a single supply, add a second power supply.
If using more than 40 receivers with dual power supplies, reduce the load of
active receivers. If the system does not have too many loads, this may indicate a
defective Cat5 output cable (could be either the active or passive receivers).
Troubleshoot by unplugging one receiver at a time and see if the fault clears.
During this type of testing it may be helpful to change to Self-clearing fault
mode.
Fan A or B RPM Low or OFF – May indicate the fan is clogged with dust.
Remove the power supply units and clean with compressed air. May also
indicate a mechanical failure of the fan. Replace the power supply unit or
contact the factory for repair options.
