What you should do in case of a malfunction depends on the type of malfunction. First, check if the problem occurs in one of the following common situations:

• System no longer communicates:
  ➤ Check if the voltage is at least 6 volts
  ➤ Restart the system (turn off the power and turn it back on)
  ➤ If this does not help, replace the card reader and send the old one to our RMA department

• Fill level remains at 0% or starts too high:
  ➤ Check the set depth of the container
  ➤ The service desk can assist with reading the correct depth

• Lock behaves strangely (stays open or closes immediately):
  ➤ The magnetic sensor may be misaligned
  ➤ The sensor must make/break contact at the correct drum position

• Card does not work:
  ➤ Check if the card reader responds
  ➤ Watch for error codes such as N04 (not in whitelist) or E99 (too low voltage)
