Imbalance Behaviour
•
install available and empty rotors and check the imbalance behaviour with rotor
dependant cut off and run through weights and replace worn out motor rubber mounts,
the motor if required or adjust the imbalance switch
2.1.2
Maintenance Routine after Dismantling the Centrifuge Casing (see Section 5)
2.1.2.1
Motor Supporting Elements
•
check the supporting and damping motor elements and replace them at least every 3
years. We recommend a yearly change. A maintenance kit is available
2.1.2.2
Imbalance Switch
•
check the function of the imbalance switch and if necessary readjust it (adjusting
procedure see 2.4)
2.1.2.3
Braking Circuit
•
check the function of the braking circuit (warming up of brake resistor, even and
noiseless brake effect) and replace defective parts in case of malfunction
2.1.2.4
Ventilation and Proper Air Flow
•
check the function of all fans (parallel cut in and out) and the air flow direction (to motor
and condenser from outside)
•
check the air inlet slots in the casing and at the rear panel for free ventilation, insufficient
air flow will lead to an inadmissible temperature rise of compressor, motor and
electronic parts
2.1.2.5
Lead and Screwing Connections
•
check the terminal and plug connections of leads on all boards and electrical
components and replace defective parts
•
check the screwing connections of boards, mechanical and electrical components and
re-tighten them if necessary
2.1.2.6
Protection Earth Core and Grounding Connections
•
check the protection earth core for continuity and all grounding plug connectors (see
also 2.6 Electrical Safety Check)
•
check insulation resistance and leakage current (see 2.6)
