OPERATION (CONTINUED)
S ETTING THE I NCUBATOR T EMPERATURE
1. Using a coin or other flat metal implement, 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 setting a new temperature for the incubator.
2. Press either the Up or Down key one time on the Temperature Control sub-panel to
activate the temperature set point mode.
3. The Set Temperature digital display will briefly flash the letters “SP” for Set Point. The
display will then go from bright to dim, and start to blink. The display will now show an
adjustable temperature set point.
4. Use the Up or the Down Arrow keys to adjust the set point to the temperature you want
the incubator to run at.
5. If neither key is pressed within 5 seconds, the Set Temperature display stops blinking and
returns to displaying the current temperature of the incubator.
6. After selecting your set point, wait 5 seconds. The display will stop flashing, and the set
point is now saved in the temperature controller. The incubator will now adjust to match
your set point.
7. Set the Over Temperature Limit System, using the procedure below.
Note: Sheldon Manufacturing recommends waiting for 24 hours for the incubator temperature to
stabilize prior to loading samples.
S ETTING THE O VER T EMPERATURE L IMIT
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. Turn the Over Temperature Limit control dial counterclockwise until the Over Temp Limit
Activated light illuminates and the audible alarm buzzes.
3. Slowly turn the Over Temperature Limit control dial clockwise until the light and audible
alarm turn off.
4. This adjusts the Over Temperature Limit control to approximately 1 ˚ C above the
temperature configured by the Set Temperature control.
The Over Temperature Limit System will activate if the incubator temperature exceeds the
temperature setting of the OTL System. If the main temperature controller system has failed, or the
OTL is set below your chosen temperature set point, the OTL alarm will buzz and continue to turn
on and off indefinitely. Contact
