ASF is a monitoring device that automatically follows the set temperature setpoint within an
adjustable tolerance band (Fig. 20).
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
first time (section A).
When the temperature violates the set tolerance band around the setpoint (in the example in
Fig. 20:
50 °C ± 2 K) – e.g. if the door is opened during operation (section B of illustration) – the alarm
is set off. The ASF alarm is automatically triggered as soon as 50 % of the set tolerance band
of the setpoint (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 the tolerance range of
the new temperature setpoint is reached again (section E).
