Data Communications & Alarm Interface; Rs-232 Interface - Fisher Scientific Isotemp Series User Manual

Product Description
Data Communications & Alarm Interface
The work space temperature sensor provides the inputs to the incubator's built-in controller,
which continuously compares the measured values to the user-specified set value and adjusts
the heaters according to the result.
The unit features a thermal protection function that is factory-preprogrammed and not
adjustable. It protects the cultures in the work space from overheating: Thermal protection
kicks in on a brief violation of the upper limit, based on the defined setpoint temperature, at
between 2 and 3 °C (35.6 °F and 37.4 °F) (37 °C (99 °F): 2 °C (35.6 °F), > 50 °C (122 °F):
3 °C (37.4 °F)), automatically reducing the work space temperature to the user-specified set
value and allowing the incubation process to be continued even in case of a controller
malfunction. If the thermal protection is activated, the error message (E111) "Temperature
too high" appears in the display window and an audible alarm is sounded.
When the user acknowledges the error message, the red alarm icon (D4 in
page 7-1) is illuminated and the Temperature Set Value icon (see
highlighted by a red border to indicate that thermal protection has kicked in.
Data Communications & Alarm Interface
All signal connections are installed in the electrical interface panel at the rear of the incubator.
