OPERATION
Over Temperature Limit (OTL) System
The OTL system is a user-set, mechanical heating cutoff connected to a hydrostatic sensor probe inside
the incubation chamber. The system operates independently of the main microprocessor temperature
controller and routes power away from the incubator heating elements if the chamber temperature
exceeds the OTL temperature cutoff setting. It will continue doing so as long as the chamber temperature
remains above the OTL setting. This helps safeguard the unit by preventing runaway heating in the event
of electronics failures or a sudden external heat spike.
The OTL must be set by the user in order to function
. The manufacturer recommends a setting of
approximately 1°C above the highest temperature setpoint of your heating application. A red indicator
illuminates and an audible alarm sounds when the OTL is rerouting power. Failure to set the Over
Temperature Limit system voids the unit manufacturing defect warranty in the event of an overtemperature
event.
