This alarm indicates excess pressure or too low value in the hydraulic circuit for proper operation.
This error normally `is related to the hydraulic circuit pump and appears during a treatment process.
If the unit beeps intermittently before the alert appears, it indicates that there is excess pressure in
the circuit due to possible obstruction of one of the applicators. If the alarm appears without previous
beeps indicates that there is no pressure in the circuit and the pump is not working.
To check these values and identify the problem in SW versions equal or higher than xx.15, it is
necessary to access to code screen, enter the code 0004 and press the light icon (marked on the
image in red). This code drives the pump and the current pressure value appears in the display.
On the other hand, if on the machine is installed SW versions olded than xx.15, the pressure value of
the pump could be checked directly on the treatment screen.
Option 1 - Versions higher or equal to xx.15:
