Page 31: Control Overview
CONTROL OVERVIEW Over Temperature Limit (OTL) This graduated dial sets the mechanical heating cut-off for the Over Temperature Limit system (OTL). The OTL helps prevents unchecked heating of the chamber in the event of an electronics failure or external heat spike. For details, please see the Over Temperature Limit System description in the Theory of Operations (page 33). - Page 32 CONTROL Alarm Mute Button Only visible when an alarm is active. When an active alarm is muted, the red background disappears. Temperature Setpoint Button Tap to set the incubation chamber operating temperature. Heating Indicator This icon functions as a two-part display. The oval at the bottom is an on / off indicator, illuminating green when the incubator controller calls for power to the heating elements.
-
Page 33: Operation
OPERATION HEORY OF PERATION Note: Each incubator chamber in a SMI12 is independently powered and heated. Heating When powered, the incubator heats to and maintains a user-selected target setpoint in the incubation chamber. The incubator senses the chamber air temperature using a solid-state probe mounted on the chamber interior wall. -
Page 34: Put The Incubator Into Operation
OPERATION UT THE NCUBATOR INTO PERATION Perform the following procedures and steps to put the unit into operation after installing it in a new workspace environment. Reminder: All procedures in the Installation chapter must be carried out before putting the unit into operation. ... -
Page 35: Set The Date And Time
OPERATION ET THE ATE AND The incubator date and time are used for logging temperature, event, and diagnostic information. 1. From the homepage open the Settings Menu. Tap the Settings gear button. 2. Open the Date and Time Menu. Tap the Date and Time clock button. 3. -
Page 36: Adjust The Temperature Setpoint
OPERATION DJUST THE EMPERATURE ETPOINT Note: Each SMI12 incubation chamber temperature is set separately The incubator comes from the factory set to 37°C. Before starting this procedure, turn the OTL dial clockwise to its maximum setting, if not already set at max. This prevents the heating cutoff system from interfering with this procedure. -
Page 37: Adjusting The Temperature Deviation Alarm
OPERATION DJUSTING EMPERATURE EVIATION LARM Note: The alarms for each incubation chamber must be set independently for SMI12s. The incubator comes with the deviation alarm enabled set to activate if the chamber temperature deviates from the setpoint by ±1°C for 1 minute or longer. See page 41 for a description of operating conditions that will stop the alarm from activating. -
Page 38: Set The Over Temperature Limit (Otl)
OPERATION Note: Test the OTL system at least once per year to verify its functionality. Failure to set the OTL voids the manufacturing defect warranty if over-temperature damage occurs. (OTL) ET THE EMPERATURE IMIT This procedure sets the mechanical heating cutoff to approximately 1˚C above the current chamber temperature. -
Page 39: Passcode Locking The Settings
OPERATION ASSCODE OCKING THE ETTINGS This procedure locks the temperature setpoint and other settings with a numeric code of your choosing. Users will be prompted to enter the code when attempting to change the settings of a locked unit. 1. Open the Service Functions menu. 2. -

OPERATION Muting the Audible Alert Tapping the mute icon mutes the currently active alarm. The audible alert remains silent until the alarm deactivates or until • another alarm activates. The mute icon disappears when the alarm deactivates. Alarm Muted Deactivating an Alarm Alarms deactivate when the unit returns to normal operating conditions. -
Page 43: Power And Memory
OPERATION OWER AND EMORY The incubator stores the data log, temperature setpoint, and other settings in non-volatile memory. The unit retains log data and its settings indefinitely in the event of a power outage. The incubator logs the chamber temperature and setpoint once per minute. It also logs events. Alarm activations are logged the moment the alarm is activated. -
Page 44: Data Log Copy And Export
OPERATION OPY AND XPORT The incubator copies and then exports user-specified date ranges of the log as human-readable .CSV spreadsheet files. Copying and exporting requires a USB A thumb drive. Note: This process does not erase log data on the incubator. 1. - Page 45 OPERATION 4. Optional: Change the autogenerated filename. The autogenerated filename consists of the model, unit serial numbers, start date-and-time • block, and the end date-and-time block. Use the keypad to enter a new filename and then save. • Note: Entering the file name of a data log file already on the USB drive appends the new date range to the existing spreadsheet rather than overwriting the original file or any data in it.

Page 46: Real Time Data Outputs
Note: The jack ports output once every 60 seconds. The USB port is only for copying and exporting the data log. It does not output data in real time. CCESSORY XPANSION This 24-volt port powers and supports SHEL LAB accessories. Only plug in devices specifically authorized for this port. UMIDIFYING THE NCUBATOR Long-term use of a large water container, such as a humidifier pan, will create excess water vapor in the unit and can damage the electrical components of an SMI incubator. -
Page 47: Condensation And The Dew Point
OPERATION ONDENSATION AND THE OINT Relative humidity inside the incubation chamber should never be allowed to exceed 80% at 25°C. Exceeding this threshold will likely result in condensation and leaks around the incubator and may cause corrosion damage if allowed to continue for any significant length of time. Condensation takes place whenever the humidity level in the incubation chamber reaches the dew point. - Page 48 OPERATION 48 | P a g e...
