Description
A shutdown warning will appear in the event of:
• A too low or too high dew point temperature
• A too high ambient temperature
• A drain fault
The dryer remains running. Alarm LED (5) is lit. The alarm disappears automatically when the abnormal
condition ends.
Dew point temperature warning
If the dew point temperature is lower than the programmed value (default value -0.1 °C (31.8 °F), see section
Calling up/modifying low dew point setting
) or if it exceeds the warning level (see section
flexible alarm and fixed alarm
), alarm LED (5) will light up and the related pictograph (dew point) starts
flashing.
Main screen with dew point temperature warning
In the example shown, the dew point is 20 °C (68 °F) and the dew point icon is flashing.
If the dew point becomes normal again, the alarm will disappear.
High ambient temperature alarm
If the ambient temperature is higher than the programmed value (default value 50 °C (122 °F), see section
Calling up/modifying high ambient temperature setting
) during at least 25 seconds, but still below 60 °C (140
°F), alarm LED (5) will light up and the related pictograph (ambient temperature) starts flashing.
Main screen with ambient temperature warning
In the example shown, the dew point is 30 °C (86 °F) and the ambient temperature icon is flashing. See section
Calling up ambient temperature
to check the temperature.
If the ambient temperature drops again below the programmed value, the alarm will disappear.
