Preselection Of Running Time; Preselection Of Brake Intensity And Acceleration - OHAUS Frontier FC5515 Manual De Instrucciones

TM
Frontier Centrifuge FC5515/FC5515R
As long as no rotor is inserted, the speed is adjustable between 200 rpm and maximum revolution of the centrifuge.
If there is a rotor in the centrifuge the speed can only be pre-selected until the maximum permissible revolution of
that rotor. It is the same with the pre-selection of the RCF-value. The setting range is between 20 x g and the
maximum permissible centrifugal force of the rotor.
See "Table 4: max. speed and RCF-values for permissible rotor" (See APPENDIX). All important values are
listed there.
ATTENTION:
Please also check the maximum permissible revolutions of your test tubes with the manufacturer.

Preselection of running time

The running time can be pre-selected in three different ranges from 10 seconds up to 99 hours 59 minutes.
1. Range from 10 seconds up to 59 minutes 50 seconds in steps of 10 seconds
2. Range from 1 hour up to 99 hours 59 minutes in steps of 1 minutes
3. The continuous run "cont", which can be interrupted by the key "Stop"(10) (refer to figure 17).
The running time can be pre-selected with the lid open or closed.
To activate the setting of the running time press the key "Time" (6).
In the display "Time/Prog" (A-3) flashes the indication "m : s" or "h : m", depending on the previous setting.
To set the desired value, use the adjusting knob (1). After exceeding 59 min 50 sec the indication changes
automatically into "h : m". After exceeding 99 hours 59 min the word "cont" appears in the display "Time/Prog"
(A-3). That continuous run can only be interrupted by pressing the key "Stop" (10). The time countdown starts as
soon as the set speed is reached.
The display always shows the remaining running time. (See figure 17)
3.3.3

Preselection of brake intensity and acceleration

This function is activated through the key "Accel/Decel" (5) (refer to figure18).
By pressing the key once the word "accel" (M7) flashes in the display "Acc/Dec" (A-2). The desired acceleration
can be pre-selected by the adjusting knob (1). The value 0 is equivalent to the lowest and the value 9 to the highest
acceleration.
By pressing the key "Accel/Decel" (5) twice, the display "Acc/Dec" (A-2) indicates the word "decel"(M8). Now
the desired brake intensity can be pre-selected by the adjusting knob (1). The value 9 is equivalent to the shortest
and the value 0 to longest possible brake time.
See "table 5: acceleration and deceleration times" (APPENDIX). There the acceleration and deceleration times
for the acceleration and deceleration stages 0 to 9 for permissible rotors are shown.
