Labnet 311DS Environmental Shaking Incubator (I5311-DS and I-5311-DS-230V) - Manual (Page 5)

-Heating Indicator-This indicator will illuminate GREEN when the controller is calling for heat
from the heater. This indicator will be on continuously while the oven heats up to the set tem-
perature and will then cycle on and off at the set temperature.
-Safety Thermostat-The safety thermostat located on the back of the unit is manually set and
completely independant of the Main Termperature Controller. The safety gurads against any
failure of the Main Controller that would allow temperature to rise past the safety set point. If
the temperature rises to the safety set point, the Safety takes control of the heating element
and allows continued use of the incubator until the problem can be resolved or service can be
arranged.
-Safety Indicator-This indicator wil illimunate RED when the Safety Thermostat is activated.
Under normal operating conditions this indicator should never be on.
-Chamber Light Switch-This switch turns the chamber light on and off when power is on.
-SHAKER CONTROLS-The shaker controls are also microprocessor based.
-RUN lamp-This lamp illuminates when the shaker is started and stays illuminated when the
shaker is running.
-Timer lamp-This lamp is illuminated when the shaker display is in the time display mode
counting down the remaining run time or showing the set run time.
-RPM lamp-This lamp illuminates when the shaker display is speed display mode showing the
current shaking speed or showing the set shaking speed.
-Stop / Start-This pad starts and stops the shaking mechanism and causes the RUN lamp to
be illuminated.
-Push to Shift / Turn Set Knob- This encoder provides the following multiple functions:
•
It increases and decreases the shaker speed setting in 1 rpm increments from 20 rpm
to 300 rpm.
• It increases and decreases the run time setting from 30 seconds to 99 minutes and 50
seconds and HOLD (Hld) for continuous operation. Time is changed in 1 second
increments to 10 minutes and then 10 second increments thereafter.
• It shifts the shaker display from time display to speed display and back
-Shaker Display- This three digit display shows the shaker speed setting or shaker time
setting or remaining shaker run time while counting down. It also shows:
•
Hld - When the shaker is set for continuous un-timed running
• Opn - When the incubator door has been opened, automatically stopping the shaking
motion (note the timer continues to count down but is not displayed)
• End - When a timed shaking run has ended
• F60 / F50 - When the shaking incubator is first powered up indicating the line
frequency of the power line.
-Door Open Switch - This switch senses when the incubator shaker door is open and sends
a signal to the microprocessor which causes the shaker to stop running as a safety measure.
However, in a timed run, the timer will continue to count down when the door is open. Closing
the door restarts the shaking motion.
