4-2 Model 310 Series DH Incubator
In addition to other safety features designed into Model 310 Series
incubators, a thermostat is also provided to monitor the cabinet's
temperature. In the unlikely event of a temperature control failure, the
thermostat will turn off all heaters at a cabinet temperature of 65°C,
±10%. This is intended to be a safety feature to protect the incubator, and
is not intended to protect the cell cultures or the equipment inside the
chamber should a temperature control failure occur.
The microprocessor in Model 310 Series incubators continually scans all
available sensors to ensure that they are operating properly. Should an error
be detected, the incubator sounds an alarm and displays the appropriate
message. If such an alarm occurs, contact your local distributor or the
Technical Services department at 740-373-4763 or 1-800-438-4851 (USA
and Canada) or fax 740-373-4189.
If the cables or connectors between the main microprocessor board and the
CO sensor or between the CO

CO units become loose or disconnected, the CO2 SENS ERR alarm

occurs.
I/R Units
On I/R incubators, the red light on the I/R module (see Figure 5-8 for
module circuit board location) will be lit continuously if communication is
lost between the CO board and the sensor head. The CO

On will not clear the alarm. Only proper connection of all components
will correct the alarm.
