CHAPTER 7 – TROUBLE SHOOTING
7.1
Introduction
The general working principle of any Konfort equipment is essentially
based on the information (physical quantities) which come from the
sensors, the load cells and the pressure transducers.
The most efficient method for diagnosing any potential failure of the
equipment is determined by a good knowledge of the tool and by a
careful analysis of the different phases of its operation: these two
prerequisites are fundamental in order to be able to isolate the possible
cause of the problem.
For example, if the equipment is showing a problem related to an
inaccurate measurement of the quantity of refrigerant during the charge
phase,
the
replacement
recommended; conversely, if the Konfort equipment never ends the
recovery phase, the carry out of a calibration of the main load cell is not
strictly necessary.
In order to determine whether, during a certain phase, the sensors
involved in it are faulty or inaccurate, the correctness of their measured
quantities
should
appropriate sample quantities, which must be known and which can be
taken as a reference.
In this regard, a useful aid is provided by the equipment's Service menu,
in particular by the Power outputs function.
In the next paragraphs, some of the most common problems, which
might
be
encountered
equipments, will be listed. For each individual critical situation, all the
steps needed for the quick identification of the cause of the problem and
for its correct solution will be described.
