Standard Function – Temperature Control (Heating and Ventilation)
Function
Temperature is controlled by two cross-flow fans (1), each of which is
connected to a downstream heating element. The cross-flow fans en-
sure constant air circulation, and keep the temperature distribution in
the incubation chamber as constant and gradient-free as possible.
The maximum possible temperature in the incubation chamber is
65°C, the minimum 6°C above the ambient temperature. In order to
achieve temperatures below the ambient temperature the device can
be fitted with an optional cooling system (see chapter 3.3.3 "Op-
tional Cooling Function", page 26).
A Pt100 temperature sensor behind the rear wall (2, not visible)
measures and controls the temperature. Each of the two cross-flow
fans is fitted with a thermostat that switches the heater off at 80°C
in order to prevent overheating.
Protection
The incubation shaker has two forms of protection against overheat-
ing:
A capillary thermostat with a control knob (1) (can be adjusted
by the owner; factory setting: 70°C)
A safety fuse (84°C)
Operation
The heater is operated using the “Temperature” (°C) parameter. For
an exact description of how to set the parameters, see chapter 6.4
"Adjusting, Activating and Deactivating Parameters", page 65.
