Help pageTacho on display means the motor has not seen a revolutionin 4 seconds. IT DOES NOT ALWAYS MEAN A TACHOMETERFAILURE. The use of tubes that are too long, or an obstructioncan cause the same effect. Alternatively, a motor invertor orboard failure meaning no power or revolution to the motor.Check the tubes and rotation first with an empty rotor. If itturns, then tubes are the problem. If it doesn’t turn, then thiswould be the motor, invertor to the mains is at fault.Always check that the display is lit, and the lid locks are fine.Check tachometer using Test 13. See page 3.Bal on display means an imbalance has occurred If this baldisplay does not clear on restarting, then the detector or it’s5 volt lines are broken. Check back to the circuit board. Thedetector is wired closed. A break in the 5 volt line will showthis display. See page 16.ALWAYS WEIGH AND OPPOSE SAMPLES IN AN EVENFASHION IN THE ROTOR. This ensures a long life and goodseparations.Lid on display means the lid is not closed properly. Push downhard on both edges of front section of lid.It is imperative that you use a good strong work surface forany centrifuge to optimise separation and reduce noise.Recomendations lid adjustment.Centralise using not under lid latch2Centurion Scientific Ltd
Codes shown on theLED DisplayUUAlt- Wait 5 seconds press Lid open againOPEn - You may now open the LidtAcho? - Check that your tubes are not toolong and fouling the lid or anything else isstopping rotation of the rotor.Lid? - Close the LidbAL? - An imbalance has occurred Please check the tubes are diagonally opposite andof the same weight.Check if the tubes are broken If so use better quality, or if glass reduce the speed to themanufacturers recommended G force.NOTE: If drucH or drIuE (drive) show please Contact Service Department, or refer to technical manual.CR 2000 model onlyyrotor? - The sensor has found the speed to be incorrect to the rotorssettings, it will have readjusted.
