Alarm messages are displayed in plain language on the screen of the op- erator device.

The display of alarm messages in the operator device can only be erased by pressing the ”ACK” key. The failure is not repaired.

A failure is given by flashing of the LED “alarm”. If the alarm message is acknowledged by pressing of the “ACK” key, but the failure is not yet eliminated, the flashing changes to steady light.

If a cooling appliance is present: If the temperature inside the switch box is higher than +50 °C (122°F), the lamp ”alarm - temperature inside switch box” goes on. If the temperature is still too high after 30 minutes, the dryer is switched off.

Failures must be repaired immediately.

LED “ALARM”:

flashes in case of an error;

is on if the error has been acknowledged but not yet eliminated; is off if there are no errors

Press the ”K2"-key.
