B.6 External devices are integrated in program mode, e.g. DAY/NIGHT simulation.
Customer wish/description: Customer would like to simulate the
ambient conditions (light and temperatur
e) for its organisms (e.g.
plants) daily.
The samples should be charged as follows:
■ The day is simulated with +22 °C and 16 "daylight hours".
■ The night is simulated with +18 °C and 8 "night hours".
■ The incubator is operated 24/7, even over the weekend.

PS Program segment
Note:
The example describes a classical DAY/NIGHT program.
The customer also requires the following items in addition to the
standard equipment:
■ The device must be equipped with the Switchboard option
(exter
nal socket strip).
■ There must be a separate light source (e.g. light slide-in module)
which can be used to simulate DA
Y (light). The customer inte-
grates this slide-in module into the incubator and connects it with
the Switchboard.
Observe the heat compensation curve
Chapter 6.14 ‘Heat com-
pensation’ on page 118
.
This example shows how the external contact can be used. In this
case, this is a light slide-in module, but other external devices (e.g.
shaker) can also be integrated into a program this way.
