3.5 Undertemp Safety Control, Indicator Light and Audible Alarm
The undertemp safety thermostat should be set slightly lower than the operating
temperature of the incubator. In the event of an undertemp condition, the undertemp
safety thermostat will:
1. Activate the audible alarm and the undertemp indicator light.
2. Shut off power to the refrigeration system and maintain the temperature at the
undertemp control point.
The undertemp control is not directly calibrated. The numbers (0 to 10) on the dial are for
reference only and do not correspond to any specific temperature. When an undertemp
condition occurs, the cause of the problem must be determined and corrected before normal
operation under the main temperature controller can be resumed.
3.6 Temperature/Humidity Controllers
The Watlow Series 982 microprocessor based controllers control the temperature and
humidity functions of the incubator. Refer to Figure 3-3. Refer to the Watlow manual
included with this manual and the Watlow configuration records at the end of Section 2.
