Operation and control
5.4.3 Automatic temperature monitor (ASF)
ASF is a monitoring device that automatically follows the set temperature setpoint with-
in an adjustable tolerance band.
The ASF – if switched on – is automatically activated as soon as the actual temperature
value reaches 50 % of the set tolerance band of the setpoint (in the example: 50
°C
±
1
K) for the
fi
rst time (section A).
If the set tolerance band around the setpoint (50
°C ± 2 K) is left – e.g. if the door is
opened during operation (section B of illustration) – the alarm will be set off. The ASF
alarm is automatically terminated as soon as 50
% of the set tolerance band of the set-
point (in the example: 50
°C ± 1
K) are reached again (section C).
If the temperature setpoint is altered, the ASF is automatically disabled temporarily (in
this example: The setpoint is changed from 50
°C to 25
°C, section D), until it reaches
the tolerance range of the new temperature setpoint (section E).
