4. Error and error correction

This chapter is directed at the operators of the equipment.

This chapter assumes general skills in dealing with drying systems and SPS (PLC) control units.

This chapter assumes that the “start-up” description has been read and understood.

It should be ensured in each and every case that the operators have the relevant skills.

&An alarm is indicated by flashing light of the button “Alarm”.

If the alarm message is acknowledged by pressing the button “Alarm”, but the failure is not yet eliminated, the flashing changes to steady light. If the failure is repaired the light is off.
