CONTROL PANEL OVERVIEW
Figure 10: Control Panel SRI3P
Power Switch
The main power switch on the control panel (green lighted I/O) controls all power to the unit and must be
in the I/ON position before any systems are operational. The switch will be lighted when in the I/ON
position.
Main Temperature Control and Green Digital Display
The SRIP incubator control panels comes with a green digital display that shows the temperature within
the incubator unit’s chamber accurate to 0.1°C, and the user-selected temperature set point. The control
is marked Set Temperature and consists of an UP/DOWN arrow pad for inputting set point temperatures,
adjusting the time, and performing calibrations.
Heating and Cooling Light
The green pilot light located beneath the label TEC ACTIVATED should be ON whenever the Peltier TEC
device is actively heating or cooling the chamber. This light should be ON nearly all of the time.
Set Over Temperature
This graduated dial sets the temperature set point for the Over Temperature Limit backup system. The
OTL System operates independently of the Main Temperature Controller, and prevents uncontrolled
heating of the Main Chamber in the event of a Main Temperature Controller failure. For more details,
please see the explanation of the Over Temperature Limit System in the Operation Section.
OTL Light
The red pilot light marked OVER TEMPERATURE ACTIVATED will illuminate when the Over
Temperature Limit System has taken control of the incubator. Under normal operating conditions this pilot
lamp should never illuminate.
Fuse
Located on the top back of the unit inside the cord inlet, the fuse protects against over current conditions.
If the fuse blows, the unit will shut down. For your safety and the safety of laboratory personnel the cause
of a blown fuse should be determined prior to replacing it.
16 | P a g e
.
OPERATION
THEORY OF OPERATION
Each SRIP incubator uses a Peltier thermoelectric cooling-and-heating device and an air circulating fan in
conjunction with a Proportional-Integrative-Derivative feedback temperature controller board to achieve
precise control over temperature levels in the incubator chamber. The temperature sensor located in the
air stream senses temperature deviations from the set point. The PID Controller Board uses feedback
from the sensor and error calculation functions to ensure a high degree of thermal stability – avoiding
overshooting or undershooting the user-selected set point when heating and cooling the chamber. This
results in precise and highly efficient cooling and heating operations with minimum power use. The
circulating fan provides even air distribution throughout the chamber and assures temperature uniformity
around the unit’s entire shelf space.
DOOR ALARM
The SRIP incubator is equipped with a magnetic induction door alarm which activates when the door is
open and the sensor components are out of range of one another for more than sixty seconds (1 minute).
When the alarm system is active an audio alarm will sound and the control panel display will flash.
Leaving the door open for extended periods will disrupt temperature uniformity within the incubator
chamber, and may result in significantly increased power use as the temperature controller board
attempts to compensate for the disruption.
ACCESSORY COMPATIBILITY
Make sure that any accessory equipment you will be using inside an SRIP incubator can safely and
effectively operate within your selected temperature range.
THE OVER TEMPERATURE LIMIT SYSTEM
The OTL is a backup heating control system that operates independently of the unit’s digital Main
Temperature Controller board. In the event of a failure of the controller board while in its heating mode,
the OTL system prevents runaway heating by depowering the peltier thermal electric heating and cooling
unit.
The OTL will not prevent a rise in heat caused by a failure of the peltier itself.
Note: The OTL system should be tested at least once per year using the Set The Over Temperature
Limit procedure.

OPERATION (CONTINUED)
SETTING UP THE INCUBATOR
Perform the following steps and procedures to prepare the incubator for use each time it is installed in a
new location:
1. Verify the workspace’s power supply and incubator’s data plate requirements match.
2. Check that the fuse is installed in the power inlet.
3. Plug the power cord into an earth grounded electrical outlet.
4. Place the Power switch in the ON position.
5. Complete the following procedures in order:
a. Set the Temperature Set Point
b. Calibrate the Temperature Display
c. Set the Over Temperature Limit Control
SET THE TEMPERATURE SET POINT
Perform these steps to prepare the unit for calibration.
1. Turn the Over Temperature Limit control dial clockwise to the maximum position indicated by
the largest dot. This prevents the Over Temperature Limit system from interfering with the set
point and calibration procedures.
2. Press either the Up or Down key one time on the Temperature Control panel to activate the
temperature set point mode. The Set Temperature digital display will start to blink, going from
bright to dim. Some models may briefly display the letters “SP” to indicate a Set Point is being
displayed. While blinking, the Set Temperature display shows an adjustable temperature set
point.
3. To change the set point, press either the Up or the Down key to adjust the set point up or down.
If neither key is pressed within 5 seconds, the Set Temperature display stops blinking and returns
to displaying the current temperature of the incubator.
4. Adjust the set point to the temperature you will use during normal operations.
5. Wait 5 seconds after entering your set point. The display will stop flashing, and the set point is
now saved in the controller. The incubator will now automatically adjust to match your set point.
18 | P a g e
.
OPERATION (CONTINUED)
CALIBRATE THE TEMPERATURE DISPLAY
Allow the incubator at least 24 hours to stabilize at its operational set point before performing a
calibration. Always use a certified temperature sensing reference device that is regularly calibrated to
0.1°C by an independent party to conduct temperature verifications or calibrations. For best results use a
remote sensing device.
1. Place the temperature sensor of a calibrated reference device inside the incubator as close as
possible to the chamber’s geometric center. Check that the sensor is not in direct contact with the
shelving.
Note: A thermocouple sensor probe’s sleeve may be taped to the shelving, as long as the exposed copper
end is 2 inches (5cm) above the shelf. An exposed sensor probe in direct contact with the shelving
may experience heat sinking, which can result in an inaccurate temperature reading.
2. Allow the temperature to re-stabilize after closing the door. The reference device’s temperature
measurement should not change for at least one (1) hour after a significant disruption for the
chamber to be considered stabilized.
3. If the reference device’s and the incubator’s temperature readings are the same, or the difference
between the two falls within the acceptable range of your laboratory protocol after one (1) hour of
stability, the incubator is calibrated.
4. If there is a difference between the two (2) readings, and that offset falls outside your laboratory
protocol’s acceptable range, adjust the incubator’s temperature display to match the reference
device’s reading. See the next step. If the door was briefly opened to take a reading, wait fifteen
minutes for the temperature to stabilize before correcting for the offset.
5. Press and hold both the UP and DOWN arrows simultaneously. The Temperature Display will
begin flashing and display the current temperature value. Adjust the current value until it
matches the reference device’s temperature reading. This will enter the offset into the unit’s
temperature controller board.
6. After matching the unit’s current value to that of the reference device, wait five seconds. The
incubator’s Temperature Display will cease flashing, and the incubator will begin heating or
cooling to compensate for the entered temperature offset.
7. Allow the incubator one (1) hour to stabilize after reaching the new temperature.
8. Compare the reference device’s reading with the incubator’s. If the reference device’s and the
incubator’s temperature readings are the same or fall within the range of your laboratory protocol,
the incubator is now calibrated.
9. If the two readings are not the same or fall outside your laboratory protocol, repeat steps 5 – 8.
10. If the temperature readings of the incubator and the reference device still fall outside your
laboratory protocol after three calibration attempts, contact Sheldon Technical Support for
assistance.
19 | P a g e
OPERATION (CONTINUED)
SET THE OVER TEMPERATURE LIMIT
Perform the following steps to set up the Over Temperature Limit system for use.
1. If you have not done so already, turn the Set Over Temperature Limit control dial clockwise to
the maximum position. This allows the Set Temperature control to stabilize.
2. Then turn the Over Temperature Limit control dial counterclockwise until the Over Temp Limit
Activated light illuminates.
3. Slowly turn the Over Temperature Limit control dial clockwise until the light turns off.
4. This adjusts the Over Temperature Limit control to approximately 1˚C above the temperature
configured by the Set Temperature control.
SILENCING THE DOOR AJAR ALARM
If the door alarm needs to be silenced, close the door, which will reset the timer. For prolonged periods
with the door open, the unit should be switched to the OFF position. If the door alarm continues to sound
when the door is fully closed, the position of the black tab-like door alarm sensor, mounted on the front
left side of the door frame overhang, can be adjusted using a screwdriver. Loosen the screws just enough
to slide the sensor and adjust. Do not remove the screws.
LOADING THE INCUBATOR
Place items on the shelves inside the incubator chamber as evenly spaced as possible. Good spacing
allows for maximum air circulation and a higher degree of temperature uniformity.
ATTACHING EQUIPMENT TO THE INTERIOR ACCESSORY OUTLET
The incubator has a 1A (maximum) accessory outlet located inside the chamber. The power switch on the
front panel controls power to the accessory outlet. This outlet can power equipment such as magnetic
stirrers, rockers, etc. Do not attach any equipment drawing more than 1A to this outlet.
Accessory equipment may produce additional heat. This heat could affect the temperature range and
uniformity of this incubator. If you are using the interior accessory outlet, you should check that the
incubator operates within required temperatures when the accessory equipment is installed and
operating.
20 | P a g e
.
OPERATION (CONTINUED)
HUMIDIFYING THE INCUBATOR
Placing only a small number of petri dishes or open media containers in the incubator chamber may lead
to excessive drying of sample media. Unusually dry environmental conditions may also contribute to
sample drying. To counteract this, Sheldon Manufacturing offers an optional humidity collection pan and
tubing accessory kit: Part Number 9900708. The kit redirects moisture that normally condenses on the
heat sink fins of the Peltier TEC heating and cooling device, and uses it to humidify the incubator. After
ordering and receiving the kit, place the stainless steel pan on the lowest chamber surface. Connect the
tubing that comes with the kit to the port on the back of the Peltier duct cover. Run the tubing down the
back of the incubator behind the shelves, and secure the end of the tubing inside the pan. The pan is
supplied with a copper slug to help prevent microbial contamination.
The humidifying kit is intended for use while running small loads. High workspace ambient humidity, or
applications that generate high levels of humidity, may result in excessive condensation on the Peltier
TEC unit. Overloading the unit with culture media can also generate excessive humidity from sample
media evaporation and blocking air flow pathways through the shelf space. Water dripping from the
Peltier duct cover at the top of the chamber onto the shelf space and floor is symptomatic of excessive
chamber humidity, and may damage the incubator.
