Controls Overview - Labnet 311D Installation And Instruction Manual

CONTROLS OVERVIEW

6.1 Power Switch: The main power ON/OFF switch controls all power to the unit. It
must be on before any systems are operational. The green switch will be lighted
when ON.
6.2 Main Temperature Control: This control consists of the digital display and
Up/Down buttons for inputting set point temperatures and calibration.
6.3 Safety Thermostat: The Safety is completely independent of the Main Controller.
The Safety guards against any failure of the Main Controller that would allow
temperature to rise past set point. If temperature rises to the safety set point, the
Safety takes control of the heating element and allows continued use of the
incubator until the problem can be resolved or service can be arranged.
6.4 Fan Switch: This operates the turbo fan inside the chamber for fast heat up times
and recovery. The switch is lighted when activated.
6.5 Safety Light: This pilot light comes ON when the Safety Thermostat is activated.
Under normal operating conditions this pilot light should never be on.
6.6 Circuit Breaker: The breaker is manually resettable and offers protection against
power source variations. Protection is in addition to the automatic high-temperature
limit designed into the heating element itself. This is located at the rear of the unit.
