3.7 Starting and stopping the centrifuge
3.7.1
Starting the centrifuge
You can start the centrifuge either with the "Start" key (10) (refer to figure 24) or the "Quick Spin" key (8).
By the "Start" key (10) you can start stored runs or runs with manually pre-selected parameters.
When the respective pre-selected running time has ended the centrifuge will stop automatically.
By the "Quick Spin" key (8) you can start runs, which will last just a few seconds.
By pressing the "Quick Spin" key (8) the centrifuge accelerates up to the pre-selected revolution.
In the display "Time/Prog" (A-4) the passed running time is indicated from the date of pressing the "Quick Spin"
key (8).
By releasing the "Quick Spin" key (8) the centrifuge stops and the running time is indicated until the opening of
the lid.
3.7.2
The "STOP" key
The run can be interrupted at any time by pressing the "Stop" key (9) (See figure 25). After pressing the key the
centrifuge decelerates with the respective pre-selected intensity until it reaches standstill.
3.8 Imbalance detection
In case of the rotor not being equally loaded, the drive will turn off during acceleration. The rotor will decelerate to a
standstill.
When in the display "Time/Prog" (A-4) the word "error" (M11) together with the number "01" appear, the weight
difference of the samples is too large. Weigh the samples more exactly and start again.
Load the rotor as described in chapter 3.1.2 and 3.1.3.
When inside the display "Time/Prog" (A-4) the word "error" together with the number "02" (See figure 26) appear,
it could be due to the imbalance switch being defective.
