RC12
BP™
Controls, Indicators, and Displays
Chapter 3: CONTROLS, DISPLAYS
The RC12BP™ controls, displays and indicators have been designed for ease of use – the control panel
(figure 3-1) allows entry with visual verification of set parameters and current conditions, prompts action
if an entry is inappropriate (remains blinking), and communicates status with user messages. An optional
Computer Interface Package allows for automatic, on-line logging of quality control and daily run data.
Figure 3-1. Control Panel and Displays
SET DISPLAY
Displays currently selected ba-
sic run parameters in the HOME
screen, advanced feature
screens (for selection of options
or programming), and user advi-
sory messages.
OPTION INDICATORS
Lights show advanced feature
selection status. If an indicator is
lit, the option is selected.
MENU
Accesses the advanced feature
screens (for selection of options
and programming).
TIME (MIN:SEC / ACE)
During a TIME run, displays remaining run time (min:sec);
during a HOLD run, displays elapsed run time (min:sec);
during an ACE run, displays current Accumulated Centrifugal
Effect™ coefficient and exponent (ACE indicator lit).
SPEED (RPM / RCF)
Displays rotor speed (rpm)
or RCF,
g
force, during a run
(when RCF indicator is lit).
TEMPERATURE (°C)
Displays the current calcu-
lated sample temperature
(°C) during a run.
RUN DISPLAY
PRIMARY FUNCTION KEYS
These keys allow access to the corresponding fields of the SET
display for the specification of new run parameters.
TEMP
Allows changing desired cal-
culated sample temperature.
RECALL
Allows viewing and selecting
programmed parameters.
ROTOR
(Future use) To allow selec-
tion of the rotor to be used.
SPEED
Allows changing desired
speed (rpm) or RCF (
g
force).
TIME / HOLD / ACE
Allows changing desired run duration; runs continue until speci-
fied min:sec times out, until STOP is pressed, or until a
specified Accumulated Centrifugal Effect™ is achieved.
START
Starts centrifuge run. Indicator
is lit when a run is in progress.
STOP
Stops centrifuge run. Indicator
is lit during deceleration.
NUMERIC KEYPAD
Inputs speed, time, and tem-
perature values; selects
programs and advanced
features (options, program-
ming). CLEAR removes an input
value or a message from the
SET display; +/– toggles
between positive and negative
for temperature value selection.
ENTER
Places input values in memory.
Bypasses advanced features
without selecting or deselecting
them.
