Cycle ends prematurely. The
centrifuge displays the error
in the RPM window

'BALANC'
'ROTOR'
7. SERVICE INSTRUCTIONS
7.1. Cleaning
•
The cabinet, rotor and accessories can be cleaned using soap and water, isopropyl
alcohol, or a 10% (5500 PPM) bleach solution
•
Apply cleaning solutions with a towel or cloth. Do not submerge the centrifuge in
water or other cleaning solutions as this will cause damage and void the warranty.
•
Under no circumstances should any of the following be used: TBQ Germicidal
Products, Fully/Partially Halogenated Hydrocarbons, Ketones or Esters.
•
The use of any chemicals not prescribed by the manufacturer may cause damage
to the rotor and tube carriers and shall not be used.
7.2. Removing the Rotor
•
Use a 1/8" hex key to loosen the center rotor screw (turn counter-clockwise).
•
Lift the rotor straight up and out of the rotor chamber.
•
To install the rotor, reverse steps A and B above. Take care to align the shaft cross-
pin with the rotor hub. Tighten the rotor screw to 3.5 Nm.
7.3. Maintaining the Rotor
•
Keep the rotor clean, any corrosive materials must not be allowed contact with the
rotor and should be cleaned immediately.
•
The rotor should be checked periodically for signs of wear.
•
Remove the rotor from service if any of the following are found: cracks, deep
scratches, corrosion or discoloring.
7.4. Rotor Screw
•
If the rotor screw needs to be tightened, use a 1/8" hex key and tighten to 3.5 Nm.
7.5. Speed Calibration
•
Check the centrifuge speed periodically, every two years is recommended.
DRUCKER DIAGNOSTICS
HORIZON 12 FLEX SERVICE MANUAL
POSSIBLE CAUSE
Rotor speed is too great - Internal error
Rotor Speed is under set speed for too long.
Rotor Speed is under set speed for too long.
Rotor Speed is under set speed for too long.
Rotor speed is over set speed for too long
Rotor improperly loaded
Debris lodged within the rotor or tube carriers
Rotor damaged
Software selection of rotor is unknown
SOLUTION
Service required
Check power supply
Check rotor – Missing carriers can reduce rotor speed in some
models. All carriers must be installed whether full or empty.
Check the lid and guard bowl gaskets. Voids in the rotor
chamber gaskets change the airflow, resulting in increased
stress on the motor drive.
Service required
Load equally filled tubes symmetrically in the rotor. All carriers
and/or tube holders must be present in the rotor, whether
loaded, or empty.
Carefully inspect all rotor pockets, tube holders and crevasses
for debris.
Replacement required
Service Required – Call Drucker technical service.
