15.1 Overview: Troubleshooting

This chapter describes what you have to do in case of problems.

It contains information about:

▪

Solving problems based on symptoms

▪

Solving problems based on error codes

Before troubleshooting

Carry out a thorough visual inspection of the unit and look for obvious defects such
as loose connections or defective wiring.

15.2 Precautions when troubleshooting

WARNING

▪

When  carrying  out  an  inspection  on  the  switch  box  of  the  unit,  ALWAYS  make
sure that the unit is disconnected from the mains. Turn off the respective circuit
breaker.

▪

When  a  safety  device  was  activated,  stop  the  unit  and  find  out  why  the  safety
device  was  activated  before  resetting  it.  NEVER  shunt  safety  devices  or  change
their values to a value other than the factory default setting. If you are unable to
find the cause of the problem, call your dealer.
