Question
What should I do if my BEST/PHI/Precision 2000 Series MLR is beeping 2 or 3 times?
Answer
Verify what power supply is being used. It should be a 24VDC power supply with at least 1.5 amps per output point.
If you are using a BEST/PHI/Precision power supply, it should be the RPSMLR2 or RPSMLR2BB.
