Fault Source Identification and Diagnostics

Description of FASIT has been described in the beginning of this guide. This screen can be displayed
behind the screen No.6 ( right arrow).
For correct evaluation the speed must be defined. The instrument can do it automatically or by user
manual entry.
As it has been described in Screen No.1 section, the machine condition is divided into 3 levels, which
have the same colours like traffic lights. The same approach we also use for fault detection.
In the left bottom corner you see the Machine icon. The vertical bar displays the overall machine
condition. This condition can be evocated by many reasons. The unit evaluates severity of 3 sources,
which are the most occurred in the practice:
- Unbalance (circle with heavy spot icon),
- Looseness (shoe icon)
- Misalignment (clutch icon).
Correspondent faults horizontal bars are in middle.
On the right bottom corner you find the rolling bearing icon. The vertical bar displays the bearing
condition. The meaning of Machine and Bearing bars was described in Screen No.1.
The temperature bar is displayed quite on right side. The ranges of colours are for less than 30°C -
green, 30-45°C - yellow, 45-60°C - orange, 60-75°C - red and for greater than 75°C – dark red.
What do the colours means in fault bars of machine and bearing?
GREEN COLOR
It may surprise somebody, because why to think about faults when the colour is green. But also from
low level signal the procedure can read the beginning of the fault. But the operation is without
restrictions.
YELLOW COLOR
The beginning level of defect is found on the machine. It is possible to operate with paying more
attention and planning of repair.
RED COLOR
There is the serious defect level found on the machine. Machine shouldn't be in operation.
