CAUTION
!
If the rotor chamber is not at the specified
temperature, it will NOT abort a spin. Press the
STOP key if you need to stop a run.
At the beginning of a spin, if the chamber
temperature differs by more than 5° C from the
specified temperature, the temperature display will
switch between the actual and set/programmed
temperatures until the two temperatures come to
within 5° C.
Main Power Switch
The main power switch is located on the left side of the
centrifuge, next to the power cord. Green= ON,
RED=OFF.
Circuit Breaker
The system provides an automatic circuit breaker for
emergency situations such as power surges that could
damage the unit. The breaker is integral to the power
switch. When tripped, the red (power off) button will
protrude from the power switch.
• If the circuit breaker trips, press the green button in the
power switch to reset the breaker.
3.6 Front Panel
IEC Centra CL5R Front Control Panel
The control panel contains numeric displays for all
operational controls. These displays have two states or
modes: Actual (bright display) and Set (dim display).
Actual Mode
In Actual mode (bright display), the display indicates
current run conditions, such as:
• rotor speed or force
• elapsed time or time remaining in the run
• actual temperature (Refrigerated only)
• program number
Set Mode
In Set mode (dim display), the display indicates the desired
settings for the run. Set mode is activated when SPEED,
TIME, TEMP., or PROGRAM are pressed, briefly at the start
of a run, or briefly after the unit is switched ON.
The numeric displays also display warning or error
messages

Function
SPEED
Switches the display from Actual to Set mode. Select
the desired speed using the numeric keypad then press
ENTER. A selection must begin before 5 seconds elapse
or the display will revert to the Actual reading.
RPM
RCF
The number in the speed/force display represents the
rotor speed in RPM or force in RCF. Press this key to
toggle between RPM and RCF. When RPM is selected
the display indicates revolutions per minute. When RCF
is selected the display indicates relative centrifugal force
in units of g. Use the numeric keys to change the set
speed or force. Select speed in increments of 50 RPM,
from 500 through 15,000 RPM (depending on the max.
allowable speed limit for the particular rotor). Select
RCF from 500 - 21,000 xg (depending on the max.
allowable RCF limit for the particular rotor) in increments
of 50 xg.
ROTOR
RADIUS
SPEED & RPM/RCF: Press these keys together to
change the radius of rotation. Select the radius using
the numeric keypad then press ENTER. Also see Section
3.4 Rotor Recognition System.
TIME
Switches the display from Actual to Set mode. Select
the desired time using the numeric keypad then press
ENTER. A selection must begin before 5 seconds elapse
or the display will revert to the Actual reading.
Time display : The number in the display indicates time.
Time is displayed as minutes:seconds up to 99 minutes,
59 seconds. The timer begins counting at the start of a
run, for example, when START is pressed. In manual
mode the timer counts down from the set point. In time
HOLD or SHORT SPIN modes
, the timer counts up.
HOLD
The hold feature is used to initiate an indefinite spin.
Press the HOLD key so that HOLD appears in the display.
Pressing START will then begin a run at the set
parameters. The timer counts up and the run will not end
until the STOP key is pressed.
SHORT SPIN
The short spin is used for quick separations. Pressing
SHORT SPIN will begin a run at the set parameters. The
timer counts up and the run will not end until the SHORT
SPIN key is released.
TEMP
(CL5R only)
The TEMP key switches the display from Actual to Set
mode. Select the desired temperature using the numeric
keypad, and then press ENTER. A selection must begin
before 5 seconds elapse or the display will revert to the
Actual reading.
Temperature display: The number in the display
represents temperature in degrees Celsius, from
−
9
°
C through
+
40
°
C.
Note: If the actual rotor chamber temperature differs by
more than 5° C from a selected set point temperature,
the °C display will switch between the actual and set/
programmed temperatures, until the two temperatures
come to within 5° C.
PROGRAM Switches the display from Manual to Program mode.
SAVE
Saves the currently displayed desired settings as stored
programs 1 through 99 (see Section 3.3). The numeric
display shows the stored program number and mode of
operation (see Section 3.2).
MANUAL
Returns the unit to manual operation from the Program
Mode.
